Biofuels are liquid or gaseous fuels primarily produced from biomass,

Biofuels are liquid or gaseous fuels primarily produced from biomass, and can be used to replace or can be used in addition to diesel, petrol or other fossil fuels for transport, stationary, portable and other applications. Crops used to make biofuels are generally either high in sugar (such as sugarcane, sugarbeet, and sweet sorghum), starch (such as maize and tapioca) or oils (such as soybean, rapeseed, coconut, sunflower).
Categories of biofuels
Biofuels are generally classified into three categories. They are
First generation biofuels - First-generation biofuels are made from sugar, starch, vegetable oil, or animal fats using conventional technology. Common first-generation biofuels include Bioalcohols, Biodiesel, Vegetable oil, Bioethers, Biogas.
Second generation biofuels - These are produced from non-food crops, such as cellulosic biofuels and waste biomass (stalks of wheat and corn, and wood). Examples include advanced biofuels like biohydrogen, biomethanol.
Third generation biofuels - These are produced from micro-organisms like algae.
Biodiesel and its benefits
Bio-diesel is an eco-friendly, alternative diesel fuel prepared from domestic renewable resources ie. vegetable oils (edible or non- edible oil) and animal fats. These natural oils and fats are primarily made up of triglycerides. These triglycerides when reacted chemically with lower alcohols in presence of a catalyst result in fatty acid esters. These esters show striking similarity to petroleum derived diesel and are called "Biodiesel". As India is deficient in edible oils, non-edible oil may be material of choice for producing biodiesel. Examples are Jatropha curcas, Pongamia, Karanja, etc.
The benefits of using biodiesel are as follows
It reduce vehicle emission which makes it eco-friendly.
It is made from renewable sources and can be prepared locally.
Increases engine performance because it has higher cetane numbers as compared to petro diesel.
It has excellent lubricity.
Increased safety in storage and transport because the fuel is nontoxic and bio degradable (Storage, high flash pt)
Production of bio diesel in India will reduce dependence on foreign suppliers, thus helpful in price stability.
Reduction of greenhouse gases at least by 3.3 kg CO2 equivalent per kg of biodiesel.

Sorghum
Sorghum (S. bicolor) is the most important millet crop occupying largest area among the cereals next to rice. It is mainly grown for its grain and fodder. Alternative uses of sorghum include commercial utilization of grain in food industry and utilization of stalk for the production of value-added products like ethanol, syrup and jaggery and bioenriched bagasse as a fodder and as a base material for cogeneration.
For more information click here(218)
Pongamia
There is several non edible oil yielding trees that can be grown to produce biofuel. Karanja (Pongamia) is one of the most suitable trees. It is widely grown in various parts of the country.
Salient features of Pongamia
It is a Nitrogen fixing tree and hence enriches the soil fertility
It is generally not grazed by animals
It is tolerant to water logging, saline and alkaline soils,
It can withstand harsh climates (medium to high rainfall).
It can be planted on degraded, waste/fallow and cultivable lands
Pongamiaseeds contain 30-40% oil.
It helps in controlling soil erosion and binding sand dunes, because of its dense network of lateral roots.
Its root, bark, leaves, sap, and flower have medicinal properties. Dried leaves are used as an insect repellent in stored grains.
Properties of Pongamia Oil
Non edible oil is largely extracted from seeds.
The collected seeds consist of 95% kernel
The oil content varies between 27 - 40%.
When mechanical expellers are used for recovery of oil from the kernels, the yield of oil is reported to be about 24 to 26.5%
The crude oil is yellow orange to brown in color, which deepens on standing. It has a bitter taste, disagreeable odour, and it’s non-edible.
Apart from use as a biofuel, the oil can be used for lighting lamps, lubricant, water-paint binder, pesticide, and in soap making and tanning industries
The oil is known to be used for the treatment of rheumatism and human and animal skin diseases.
The press cake (left over after oil extraction) is rich in Nitrogen and hence can be used for improving soil fertility. The press cake when applied to the soil, also has pesticidal value, particularly against nematodes.
Pongamia seed oil Vs standard petroleum/diesel
Pongamia seed oil as a bio- fuel has physical properties very similar to conventional diesel.
It is, however a clean fuel (eco friendly) than conventional diesel

sun watcher, India’s Aditya-L1

sun watcher, India’s Aditya-L1
Made in India probe prepares to study solar phenomena
Sometime in 2019 or 2020 India will send ISRO’s solar mission Aditya-L1 to a vantage point in space, known as the L1 Lagrange point, to do imaging and study of the sun. This launch will happen in the early part of the next solar cycle - an occurrence in which sunspots form on the face of the sun, growing in size and number and eventually diminishing, all over a period of eleven years. It will be a mission of many firsts.
The so-called L1 point is 1.5 million kilometres away. Here, due to the delicate balance of gravitational forces, the satellite will require very little energy to maintain its orbit. Also it will not be eclipsed from the sun. The 1,500-kg class satellite will be programmed to orbit this point and image the sun’s magnetic field from space for the very first time in the world. Scientists hope to capture the close-ups of the sun from here, uninterrupted by eclipses for years.
Few other space agencies have successfully placed their satellites at this location. Among the few, the Solar and Heliospheric Observatory (SOHO), a NASA-ESA collaboration involving America and Europe, and NASA’s Advanced Composition Explorer (ACE) are at L1 exclusively to study the sun and space weather, respectively. Aditya-L1 is expected to be the very first to study from space two months from the time of launch, the magnetic field of the sun’s corona. The corona is the outer layer that we see during total solar eclipses. It will be the first 100% Indian mission which will not only negotiate a challenging orbit, but will also benefit the global scientific community in understanding the sun.
Deeper look
Earlier, the NASA-ESA mission SOHO was launched in 1995, and while it made many discoveries, its coronagraph, meant to image the sun, broke down shortly after the mission commenced. Hence there is currently no satellite imaging the sun from space. Aditya-L1 will not only fill this gap it will also literally, look deeper into the sun than SOHO. “The nominal mission lifetime is expected to be five years, though it is expected to go on for much longer, perhaps even ten,” says Dipankar Banerjee from Indian Institute of Astrophysics (IIAP), Bengaluru, which is collaborating with ISRO on this project.
The mission will carry seven payloads,consisting of a coronagraph, equipment that will image the sun using ultraviolet filters, X-ray spectrometers, and particle samplers all being made within the country.
The largest payload, or instrument, aboard the satellite, will be the Visible Emission Line Coronagraph (VLEC). This can view the sun more closely than has been done before even by SOHO.
With this advantage, the instrument has the capacity to observe the loop-like magnetic structures that form in the corona, the outer layer of the sun. “This will be the first experiment to measure the coronal magnetic field from a space platform. This was not even done by SOHO,” says Dipankar Banerjee, the Science Working Group Chair of VELC.
Between them, the three payloads — VLEC, the Solar Ultraviolet Imaging Telescope (SUIT) and the X-ray spectrometers — can image the sun in all wavelengths.
Like seasonal changes on the earth, the sun experiences approximately eleven-year-long cycles during which sunspots, caused by the sun’s magnetic field, start forming, increase in the ascending phase and decrease in the descending phase towards the end of the cycle.
“Studying coronal mass ejections [a phenomenon that would correlate with high sunspot activity] is not the only objective. This study can also help us understand the coronal heating problem,” says Prof. Banerjee. The ‘coronal heating problem’ refers to the fact that the photosphere, a deeper layer of the sun, is at a much lower temperature than the outer layer, the corona. Since it is believed that the heating process happens from within, what causes this heating of the outer layer, the corona, remains a mystery. Observations by Aditya-L1 of the magnetic fields bubbling out of the photosphere into the corona will help shed light on this.
First proposed in 2008 as a 400 kg-class satellite with one scientific instrument, a coronagraph, the project has since changed and grown in size and scope. Aditya-L1 will carry seven payloads. Each of these will either image the sun or sample the space around it for traces of charged particles spewed out by the sun during coronal mass ejections.
The payloads alone will weigh close to 250 kg. The biggest of these is the VLEC, about 170 kg. The next is SUIT, weighing around 35 kg; others are much lighter. Orbiting about the L1 point, due to a play of gravitational forces acting on it, Aditya-L1 will require little energy to keep it in place.
The ultraviolet (UV) imaging payload will capture the sun using UV filters, something that is not possible from Earth. the wavelength range 200-400 nanometres. This is The range of ultraviolet light to be observed is prevented from entering the lower layers of the earth’s atmosphere by the ozone layer in the stratosphere. Ozone depletion can lead to this radiation filtering through to lower levels where it can have harmful effects. Since this radiation is stopped at the stratosphere, images of the sun in this wavelength cannot be obtained on earth. Therefore, this will be the first time a UV imaging of the sun will be done.
Durgesh Tripathi and A.N. Ramaprakash of Inter University Centre for Astronomy and Astrophysics (IUCAA) are the principal investigators for the SUIT payload. “When it was decided that the project expanded and the satellite was to be placed in L1 point, ISRO called for proposals for developing more instruments. The original payload was also improved to form the VLEC and six more payloads were added,” says Prof. Tripathi.
Apart from this, the two in situ particle-detection payloads - Aditya Solar wind Particle EXperiment (ASPEX) and Plasma Analyser Package for Aditya (PAPA) will study aspects that affect space weather. the origin of solar wind ions, their reaction to coronal mass ejections, the distribution of these in the heliosphere – the space around the sun that extends up to Pluto - and so on. The various payloads in Aditya-L1 will also study space weather.

On antibiotic resistance

On antibiotic resistance
around the time the UN Climate Change Conference drew to a close in Bonn last week, so did the World Antibiotic Awareness Week, a World Health Organisation campaign to focus attention on antibiotic resistance. The global threats of climate change and antibiotic resistance have much in common. In both cases, the actions of people in one region have consequences across the globe. Also, tackling both requires collective action across multiple focus areas. For resistance, this means cutting the misuse of antibiotics in humans and farm animals, fighting environmental pollution, improving infection control in hospitals, and boosting surveillance. While most of these goals need government intervention, individuals have a critical part to play too. This is especially true for India, which faces a unique predicament when it comes to restricting the sale of antibiotics — some Indians use too few antibiotics, while others use too many. Many of the 410,000 Indian children who die of pneumonia each year do not get the antibiotics they need, while others misuse drugs, buying them without prescription and taking them for viral illnesses like influenza. Sometimes this irrational use is driven by quacks. But just as often, qualified doctors add to the problem by yielding to pressure from patients or drug-makers. This tussle — between increasing antibiotic use among those who really need them, and decreasing misuse among the irresponsible — has kept India from imposing blanket bans on the non-prescription sale of these drugs.
When policymakers did propose such a ban in 2011, it was met with strong opposition. Instead, India turned to fine-edged tools such as the Schedule H1, a list of 24 critical antibiotics such as cephalosporins and carbapenems, whose sale is tightly controlled. But even Schedule H1 hasn’t accomplished much: pharmacists often flout rules, and drug controllers are unable to monitor them. Thus, the power to purchase antibiotics still remains in the hands of the consumer. It is up to consumers now to appreciate the threat of antibiotic resistance and exercise this power with care. These miracle drugs form the bedrock of modern medicine today, and are needed for everything from prophylaxis for a complicated hip surgery to treatment for an infected knee scrape. Losing these drugs would mean that even minor illnesses could become killers, and the cost of health care will soar. Consumers need to remember that not all illnesses need antibiotics, and the decision on when to take them and for how long is best left to a doctor. Multi-resistance in some tertiary-care hospitals to bugs like Staphylococcus aureus has grown to dangerous levels. But the experience of countries like Australia shows that cutting down on antibiotics can reverse such trends. The National Action Plan on Antimicrobial Resistance aims to repeat such successes in India. Meanwhile, awareness must be built among consumers so that they see the coming crisis and take up the baton.

bacteria can power batteries

bacteria can power batteries
Unlike conventional solar cells that operate only when exposed to light, cyanobacteria can generate an electric current both in the dark and in light.
Scientists from the Imperial College London have printed electronic circuits using cyanobacteria — microbes that can turn light into energy. Using a simple inkjet printer, they printed a carbon nanotube electrode surface and also the bio-ink of cyanobacteria on top of it.
Unlike conventional solar cells that operate only when exposed to light, cyanobacteria can generate an electric current both in the dark and in light.“Our biophotovoltaic device is biodegradable and in the future could serve as a disposable solar panel and battery that can decompose in our composts or gardens,” said Marin Sawa, author of a paper published recently in Nature Communications.
“Cheap, accessible, environmentally friendly, biodegradable batteries without any heavy metals and plastics - this is what we and our environment really need but don’t have just yet, and our work has shown that it is possible to have that,” said Dr. Sawa.
Biophotovoltaic cells contain cyanobacteria or algae that converts light into energy. Currently one of the biggest challenges facing biophotovoltaic cells is producing them on a large scale.
Researchers showed that nine connected cells can power a digital clock or generate flashes of light from an LED. The researchers also showed that the cells can generate a continuous power output over the course of a 100-hour period consisting of light and dark cycles.

Hyderabad is all set to roll out the red carpet for the Global Entrepreneurship Summit (GES-2017), a gathering of hundreds of budding, ambitious and well-known entrepreneurs as well as investors and supporters of the eco-system.
Prime Minister Narendra Modi will inaugurate it on Tuesday evening in the presence of United States President’s Adviser Ivanka Trump and Telangana Chief Minister K. Chandrasekhar Rao.
The eighth edition of the GES, which is coming for the first time to South Asia, will serve as a forum to celebrate and nurture entrepreneurship and provide opportunities to network.

A neutral Internet

A neutral Internet
The Telecom Regulatory Authority of India (TRAI) finally came out with clear guidelines in favour of Net neutrality that are consistent with its earlier stand on Facebook’s Free Basics proposal. After consultation papers issued in May 2016 and this January, the regulator reiterated that there cannot be discriminatory treatment of websites on the Internet by service providers. In particular, TRAI warned providers against the practice of blocking certain websites and tinkering with content speeds. This, in a nutshell, means that service providers such as telecom companies cannot stand in the way of a consumer’s access to content that would otherwise be provided to her without any undue hindrance. They cannot, for instance, charge consumers for access to certain content, or receive payment from websites promising greater promotion of their product over the rest. Quite notably, TRAI’s decision comes in the wake of international focus on the U.S. Federal Communications Commission’s decision to scrap regulations on service providers imposed during the Obama administration. While batting for the right to an open Internet, however, TRAI has been careful to allow some exceptions that allow companies to discriminate between content if it helps them regulate the flow of traffic or offer “specialised services”.
While TRAI’s new guidelines will help the cause of building the Internet as a public platform with open access to all, the concerns of service providers should not be dismissed altogether. The Internet has spread all over the world, so widely that many believe it is now an essential good. But the infrastructure that serves as the backbone of the Internet has not come without huge investments by private service providers. So any regulation that severely restricts the ability of companies to earn sufficient returns on investment will only come at the cost of the welfare of the public. In this connection, TRAI has been open to adopting a nuanced view that differentiates between various forms of content instead of imposing a blanket ban on all forms of price differentiation. The new policy, for instance, will still allow companies to justify the costs incurred in providing niche content to consumers. At the same time, TRAI’s measured response is likely to effectively address the problem of anti-competitive practices adopted by certain providers. Interestingly, it has left it, with important caveats, to the government to decide on services that count as “specialised” and deserve exceptional treatment by regulators. To this end, a proper mechanism needs to be instituted to make sure that the exceptions are not used as loopholes by the big Internet players. Policymakers will also need to think hard about creating an appropriate legal framework to prevent the capture of regulation by special interests.

Ethanol Blended Petrol (EBP) Programme

Ethanol Blended Petrol (EBP) Programme is being implemented by the Government of India to promote the use of alternative and environment friendly fuels. This intervention is also sought to reduce import dependency for energy requirements and provide necessary boost to the agriculture sector.
To support the aforesaid programme, Oil PSUs have decided to set up 12 Second Generation (2G) Ethanol bio-refineries in 11 States of the Country as an effective tool for development of rural economy. One such plant is being set up by Bharat Petroleum Corporation Ltd. (BPCL) in village Baulsingha, Tehsil- Bhatli, District Bargarh (Odisha) with a proposed investment of Rs. 750 crores. BPCL has already appointed Project Management Consultant for early commencement of developmental activities at the site.
BPCL has requested the State Government of Odisha through Industrial Promotion & Investment Corporation of Odisha (IPICOL) for allocation of land during November, 2016. Even after elapse of almost of one year, land allotment for the project has not been done. This is adversely affecting the project which is being pursued in the interest of the people of Odisha. In this regard, Shri Dharmendra Pradhan, Minister of Petroleum & Natural gas; Skill Development & Entrepreneurship, Government of India has written a letter to Shri Naveen Patnaik, Chief Minister of Odisha, seeking his intervention for immediate handing over of the land so that work on the project could be started at the earliest.
With the setting up of this bio-refinery, there will be an increase in the overall economic activity in the surrounding area. This bio-refinery will also necessitate setting up of around 10 decentralized biomass collection depots in a radius of 50km. There will be quantum jump in the labour and transportation activities from the agricultural fields to the biomass collection depots to the bio-refinery and movement of finished product. The demand for equipment such as bailers, compacters, loaders, tractor trolleys will also rise. During the construction of the bio-refinery, employment opportunities will also be created for the locals.
Feedstock for the plant will be agricultural waste, crop, residues from the adjoining area which will be converted into ethanol and bio-manure. While ethanol produced from this bio-refinery will supplement the EBP Programme promoted by Government of India, bio-manure will get consumed in the nearby areas thereby improving the soil fertility. The estimated feedstock consumption for this plant is 1,30,000 MT per annum. This is expected to generate a value of Rs. 8 crore per annum for the adjoining farmers for their agricultural waste which otherwise requires spending by the farmer for its disposal. Additionally, this venture will provide opportunity for rural entrepreneurs to generate direct and indirect employment for 800- 1000 persons thereby generating additional income of Rs. 10- 12 crores per annum.

ISA to become a Treaty-based International Intergovernmental organization

ISA to become a Treaty-based International Intergovernmental organization tomorrow
46 countries sign and 19 ratify the Framework Agreement of ISA
In terms of its Framework Agreement, with ratification by Guinea as the 15th country on 6th November 2017, the International Solar Alliance (ISA) will become a treaty-based international intergovernmental organization tomorrow on 6th December 2017. The ISA, headquartered in India, has its Secretariat located in the campus of National Institute of Solar Energy, Gwalpahari, Gurgaon, Haryana.
The ISA is an Indian initiative, jointly launched by the Prime Minister of India, Shri Narendra Modi and the President of France on 30th November 2015 in Paris, on the sidelines of COP-21, the UN Climate Conference. It aims at addressing obstacles to deployment at scale of solar energy through better harmonization and aggregation of demand from solar rich countries lying fully or partially between the Tropic of Cancer and Tropic of Capricorn. As of date, 46 countries have signed and 19 countries have ratified the Framework Agreement of ISA.
Signatory Countries (46)
Australia, Bangladesh. Benin, Brazil, Burkina Faso, Cambodia, Chile, Costa Rica, Democratic Republic of Congo, Comoros, Cote d’Ivoire, Djibouti, Cuba, Dominican Republic, Ethiopia, Equatorial Guiana, Fiji, France, Gabonese Republic, Ghana, Guinea, Guinea Bissau, India, Kiribati, Liberia, Madagascar, Malawi, Mali, Mauritius, Nauru, Niger, Nigeria, Peru, Rwanda, Senegal, Seychelles, Somalia, South Sudan, Sudan, Tanzania, Tonga, Togolese Republic, Tuvalu, UAE, Vanuatu, and Venezuela
Ratifying Countries (19)
India, France, Australia, Bangladesh, Comoros, Cuba, Fiji, Guinea, Ghana, Malawi, Mali, Mauritius, Nauru, Niger, Peru, Seychelles, Somalia, South Sudan, and Tuvalu
ISA Interim Secretariat has been operational as a de-facto organization since 25th January, 2016. Three programmes - Scaling Solar Applications for Agriculture Use, Affordable Finance at Scale, and Scaling Solar Mini-grids - have been launched. These programmes will help in achieving the overall goal of increasing solar energy deployment in the ISA member countries for achieving universal energy access and speeding up economic development. In addition to the existing 3 programmes, ISA has initiated plans to launch two more programmes: Scaling Solar Rooftops and Scaling Solar E-mobility and Storage.
Further, ISA has also been developing a Common Risk Mitigating Mechanism (CRMM) for de-risking and reducing the financial cost of solar projects in the ISA member countries. The instrument will help diversify and pool risks on mutual public resources and unlock significant investments. An international expert group has been working on the blue print of the mechanism and it will be rolled out by December 2018.
Another major initiative is establishment of Digital Infopedia which will serve as a platform to enable policy makers, Ministers and corporate leaders from ISA countries to interact, connect, communicate and collaborate with one another. The interactive platform was operationalized on 18th May 2017. Digital Infopedia will have three heads: (a) Member countries counter for investment opportunities; (b) at least 1000 best practices on solar energy (audio/visual), and (c) Member countries of ISA and the ISA Secretariat audio and visual interaction.
The Paris Declaration establishing ISA states that the countries share the collective ambition to undertake innovative and concerted efforts for reducing the cost of finance and cost of technology for immediate deployment solar generation assets. This will help pave the way for future solar generation, storage and good technologies for each prospective member countries’ individual needs, by effectively mobilizing more than US$1000 billion in investments that will be required by 2030.
India has offered to meet ISA Secretariat expenses for initial five years. In addition, the Ministry of External Affairs, Government of India has set aside US$2 billion for solar projects in Africa out of Government of India's US$10 billion concessional Line of Credit (LOC) for Africa. Government of France has also earmarked Euro 300 million soft loan for solar related projects in ISA member countries.

Toxic farming: on insecticide regulation

Toxic farming: on insecticide regulation
Reports of farmers dying from pesticide exposure in Maharashtra’s cotton belt in Yavatmal make it evident that the government’s efforts to regulate toxic chemicals used in agriculture have miserably failed. It is natural for cotton growers under pressure to protect their investments to rely on greater volumes of insecticides in the face of severe pest attacks. It appears many of them have suffered high levels of exposure to the poisons, leading to their death. The fact that they had to rely mainly on the advice of unscrupulous agents and commercial outlets for pesticides, rather than on agricultural extension officers, shows gross irresponsibility on the part of the government. But the problem runs deeper. The system of regulation of insecticides in India is obsolete, and even the feeble efforts at reform initiated by the UPA government have fallen by the wayside. A new Pesticides Management Bill introduced in 2008 was studied by the Parliamentary Standing Committee, but it is still pending. At the same time, there is worrying evidence that a large quantum of pesticides sold to farmers today is spurious, and such fakes are enjoying a higher growth rate than the genuine products. Clearly, there is a need for a high-level inquiry into the nature of pesticides used across the country, and the failure of the regulatory system. This should be similar to the 2003 Joint Parliamentary Committee that looked into harmful chemical residues in beverages and recommended the setting of tolerance limits.
It is incongruous that the Centre has failed to grasp the need for reform in the regulation of pesticides, when it is focussed on growth in both agricultural production and exports. Agricultural products from India, including fruits and vegetables, have been subjected to import restrictions internationally for failing to comply with safety norms. It is imperative that a Central Pesticides Board be formed to advise on use and disposal of pesticides on sound lines, as envisaged under the law proposed in 2008. This will strengthen oversight of registration, distribution and sale of toxic chemicals. There can be no delay in updating the outmoded Insecticides Act of 1968. A stronger law will eliminate the weaknesses in the current rules that govern enforcement and introduce penalties where there are none. Aligning the new pesticides regulatory framework with food safety laws and products used in health care will make it broad-based. After the recent deaths, Maharashtra officials have hinted at the loss of efficacy of some hybrids of genetically modified cotton in warding off pests to explain the growth and intensity of pesticide use. The responsible course would be to make a proper assessment of the causes. It is also an irony that the Centre has failed to use its vast communication infrastructure, including DD Kisan, the satellite television channel from Doordarshan dedicated to agriculture, to address distressed farmers. A forward-looking farm policy would minimise the use of toxic chemicals, and encourage organic methods where they are efficacious. This will benefit both farmer and consumer.

Should robots be nationalised?

Should robots be nationalised?
What robotisation can offer to the future of work in India
As we ask ourselves how employment is threatened by technology, we should look at how labour has changed in recent decades. Before we get so attached to the current job market, and feel we must defend it from an eventual robot takeover, we should examine how unfair the labour system has become and how robotics could contribute to change that.
If properly managed, the robotic revolution could be a chance to free millions of people from a system of exploitation of labour which is unprecedentedly inhumane. Or not.
In ancient Rome, a slave worked a maximum of six hours a day. A third of the year was spent in festivities. European workers in the Middle Ages had a six-hour work day and spent 150 days in religious celebrations — almost half the entire year off!
Nothing close to the 13 to 14 hours put in by the average, always-on entrepreneur of our times. Or the 10 hours a regular employee often clocks in, which explains why overwork is causing so many deaths across Asia.
The Industrial Revolution and the continuous automation of work have morphed us into becoming increasingly less human workers. This is the central premise before looking into what robotisation can offer to the future of work in India.
Is there also a continuing percolation, in India, from the agricultural sector, through urbanisation and its consequences, into the service and manufacturing sectors? Certainly.

‘Robotics revolutionising labour market’
Could this happen in a more humane way, as easily automated jobs are slowly stolen by robots? Is farming also destined to be substituted by Artificial Intelligence (AI)? Could we then envision a future of a widely urbanised class with more leisure time thanks to robots? Utopia.
But there may be a way to go in that direction, if we think about the advantages of robotisation being equally distributed among those who will lose their jobs.
A socially sensitive policy should consider this a chance for the government to gather advantages from higher robotisation and distribute them to the work force by creating job alternatives. Or by providing subsidies and employment systems with less working hours — such as part-time and work from home. Finally, robotised work should distribute earnings to those who will permanently lose their jobs. And this could be done in very specific ways.
A kind of exploitation
First, we should consider how to capitalise from the current market. The premise for doing so requires a radical change of perspective.
When we read that in a town in Andhra Pradesh, an AI company hires women and youth and spends some of its profit on education and drinking water for the community, we should not be humbly thankful. We should be worried.
But what is passed for bringing employment to underdeveloped areas is neo-colonial exploitation at its best. Workers are paid peanuts to build the very same AI that will render them obsolete. This is not explained to them. So they are thankful for an extra little water and infrastructure, in exchange.
This trick is fooling Western underprivileged people as well. To refine conversation skills, a digital AI assistant needs to be told over and over when it has failed. There are plenty of American college students spending 10 to 30 hours a week, for $10 an hour, on phones or computers as AI supervisors, evaluating search results and chats through sites such as Clickworker. If they understood the ramifications of their work, they might demand to be paid much more.

Robots that steal human jobs should pay taxes: Bill Gates
This is policy recommendation number one: enforce a high international minimum wage for all data-entry and data-supervision workers. Help people who are “feeding the machine” be better paid for contributing to coding reality into its virtual version.
There is a more serious issue in the Indian job market. In 1810, the agricultural sector was 90% of the U.S. economy. In 1910, it was down to 30%. In 2010, it was 2%.
Is this what’s in store for India, where agriculture is still occupying half of the work force? Will it happen faster here? How do we retrain farmers? And where are they to relocate?
What will happen to “the rejected” as Pope Francis called them, “the forgotten,” as U.S. President Donald Trump labelled them during his campaign?
A new era
More interestingly, will we move into a “humanistic intelligence” era in which we transform our workers, first with wearable computers (smartwatches and Google glasses are a beginning, the new smartphones operating according to moods, gaze and gestures are the next step), and then with deeper integration, like the Swedish company Biohax, implanting chips under the skin of their employees’ wrists?
It is called “shortening the chain of command”— from the smart screen era, to the cyborg era.
At first, technology might not immediately take all our jobs, it will take over our bodies. Of course, it’s already doing that. For example, I wear a hearing aid. Would I wear a bionic eye for sensory and visual augmentation, or for, say, drone operation? Maybe.
Is this how humans will compete with robots in an intermediary phase? What does it mean for society and its sense of identity, our relationship to our bodies?
There might be a lot of jobs for our new cyborg selves out there, in what is called the aug-mediated reality. Humans, some argue, are not to be defended, but expanded. So, will we be become transhumanistic, pimped-up cyborgs, with mechanical elements expanding our physical limitations? Isn’t this already happening? Is this the Nietzschean Übermensch we are supposed to become? Shouldn’t policy regulate that as well?
The focal question here is: as labour is being transformed at its roots, should economic forces be the only thing that matters? Aren’t we in front of an ethical and political, rather than an economic, question? And what if the answer is simply that everyone must benefit from the capital generated by robotisation?
Shouldn’t we begin to think of an alternative form of ownership of the robots? Shouldn’t they be public property, since they are objects that occupy and operate on public grounds, impacting public economy and nation-wide employment?
Shouldn’t they be owned by everyone? Should India consider nationalising robots? As ludicrous and anachronistic as it may sound in the post-neoliberal zeitgeist, it is something at least worth opening up for reflection.
Or could robots owned by private companies be allowed to operate only by purchasing a costly state licence, benefitting society at large or, specifically, displaced workers, thus funding unemployment?
Is it conceivable to create “job permits for robots” so that 30% of the revenue they raise with their work goes directly to finance the pension funds of the workers made redundant by robotisation?
This may not be the specific solution, but discussion should begin on these topics, as one of the ways to avoid famine and death possibly brought on by massive unemployment in a relatively short time.

Carbon dioxide levels hit record high in 2016: WMO report

Carbon dioxide levels hit record high in 2016: WMO report
Concentration of carbon dioxide in the earth’s atmosphere rose at a record-breaking speed in 2016 to reach the highest level in 800,000 years
Concentration of carbon dioxide in the earth’s atmosphere rose at a record-breaking speed in 2016 to reach the highest level in 800,000 years, a report by the World Meteorological Organization (WMO) said. The development, it said, has the potential to initiate unprecedented changes in climate systems, causing severe ecological and economic disruptions.
The WMO’s ‘Greenhouse Gas Bulletin’, released on Monday, said the abrupt changes in the atmosphere witnessed in the past 70 years are without precedent.
As per the report, globally averaged concentrations of CO2 reached 403.3 parts per million (ppm) in 2016 up from 400.00 ppm in 2015 because of a combination of human activities and a strong El Niño event. Concentrations of CO2 are now 145% of pre-industrial (before 1750) levels.
The report emphasized that the last time the Earth experienced a comparable concentration of carbon dioxide was 3-5 million years ago when the temperature was 2-3°C warmer and sea level was 10-20 meters higher than now.
It warned that rapidly increasing atmospheric levels of CO2 and other greenhouse gases have the potential to initiate unprecedented changes in climate systems, leading to severe ecological and economic disruptions.
It underlined factors like population growth, intensified agricultural practices, increases in land use and deforestation, industrialization and associated energy use from fossil fuel behind the unprecedented increases in concentration of greenhouse gases in the atmosphere since the industrial era, beginning in 1750.
According to the report, the rate of increase of atmospheric carbon dioxide over the past 70 years is nearly 100 times more than that at the end of the last ice age.
Methane, another major greenhouse gas, reached a new high of about 1853 parts per billion (ppb) in 2016 and is now 257% of the pre-industrial level.
The levels of nitrous oxide, another greenhouse gas, too reached new highs. Its atmospheric concentration in 2016 was 328.9 parts per billion which is 122% of pre-industrial levels.
“Without rapid cuts in CO2 and other greenhouse gas emissions, we will be heading for dangerous temperature increases by the end of this century, well above the target set by the Paris climate change agreement. Future generations will inherit a much more inhospitable planet,” said WMO secretary-general Petteri Taalas in an official statement.
“CO2 remains in the atmosphere for hundreds of years and in the oceans for even longer. The laws of physics mean that we face a much hotter, more extreme climate in the future. There is currently no magic wand to remove this CO2 from the atmosphere,” he added.
The report comes ahead of the UN climate change negotiations that are scheduled to be held from 7-17 November in Bonn, Germany.

Nasa says Earth’s ozone hole shrivels to smallest since 1988

Nasa says Earth’s ozone hole shrivels to smallest since 1988
Nasa says in 2017 the ozone hole is more than twice as big as the US, but it’s 1.3 million square miles less than last year and 3.3 million square miles smaller than 2015
The ozone hole over Antarctica shrank to its smallest peak since 1988, Nasa said on Thursday.
The huge hole in earth’s protective ozone layer reached its maximum this year in September, and this year Nasa said it was 7.6 million square miles wide (19.6 million square kilometers). The hole size shrinks after mid-September.
This year’s maximum hole is more than twice as big as the United States, but it’s 1.3 million square miles less than last year and 3.3 million square miles smaller than 2015.
Paul Newman, chief earth scientist at Nasa’s Goddard Space Flight Center, said stormy conditions in the upper atmosphere warmed the air and kept chemicals chlorine and bromine from eating ozone. He said scientists haven’t quite figured out why some years are stormier — and have smaller ozone holes — than others.
“It’s really small this year. That’s a good thing,” Newman said.
Newman said this year’s drop is mostly natural but is on top of a trend of smaller steady improvements likely from the banning of ozone-eating chemicals in a 1987 international treaty. The ozone hole hit its highest in 2000 at 11.5 million square miles (29.86 million square kilometers).
Ozone is a colourless combination of three oxygen atoms. High in the atmosphere, about 7 to 25 miles (11 to 40 kilometers) above the earth, ozone shields earth from ultraviolet rays that cause skin cancer, crop damage and other problems.
Scientists at the United Nations a few years ago determined that without the 1987 treaty by 2030 there would have been an extra 2 million skin cancer cases. They said overall the ozone layer is beginning to recover because of the phase-out of chemicals used in refrigerants and aerosol cans.

Founding Ceremony of International Solar Alliance in Bonn, Germany

Curtain Raiser Event held for the Founding Ceremony of International Solar Alliance in Bonn, Germany
A Curtain Raiser Event for the Founding Ceremony of the International Solar Alliance (ISA) was held at Bonn, Germany yesterday.
Speaking at the event, Shri Anand Kumar, Secretary, Ministry of New and Renewable Energy, Government of India hoped that, in the spirit of affirmative action, developed countries will earmark a percentage of Overseas Development Assistance (ODA) towards solar energy projects in developing countries. He suggested that Multilateral Development Banks and other financial institutions provide wholehearted support for solar projects through low cost finance, and research & technology institutions worldwide try their utmost to bring the cost of solar power and storage within the reach of all. Shri Kumar also invited corporates and other institutions to support solar energy development and deployment in every possible manner.
Recalling that the ISA initiative is the vision of Prime Minister of India, Shri Narendra Modi, Shri Kumar reaffirmed Indian Government’s continued support for the ISA. He also spoke about the Government plans to increase the share of renewable energy in India’s energy mix, especially towards achieving cumulative installed renewable power capacity of 175GW by 2022.
Secretary, Environment, Forest and Climate Change, Government of India, Shri C.K. Mishra, underlined the need for visualising solar energy in the context of sustainable development goals. He emphasised upon the need for arranging technologies, finance and capacity building for solar energy projects, as well as for developing storage technologies. He also suggested that there is a need to work in the areas of renewable power evacuation and application of off-grid solar energy.
Interim Director General of the ISA, Shri Upendra Tripathy, informed that ISA will become a treaty-based international intergovernmental organisation on 6 December 2017. 44 countries have already signed the ISA treaty, and many more are set to join. He spoke on the ISA’s three ongoing programmes: facilitating affordable finance for solar, scaling up solar applications for agriculture, and promoting solar mini-grids in Member Nations. The discussions also covered the ISA’s Common Risk Mitigation Mechanism (CRMM) project, aimed at de-risking investments into solar energy projects in developing countries, and thereby, encouraging flow of funds into the sector.
Speaking at the occasion, H.E. Ségolène Royal, Special Envoy for the implementation of the ISA, Government of France, emphasised upon five key points to accelerate global solar deployment: setting concrete goals, developing and leveraging common tools, enhancing projects, establishing decentralised PV solutions, and forging new partnerships that capitalise on complementary capabilities.
The ISA was jointly launched on 30 November 2015 by Prime Minister of India, Shri Narendra Modi, and then-President of France, H.E. François Hollande, on the side lines of the UNFCCC Conference of Parties 21 (CoP21) at Paris, France. The ISA is a treaty-based alliance of 121 prospective solar-rich Member Nations situated fully or partially between the Tropics, and aims at accelerating development and deployment of solar energy globally.

basics of whisky in india

ndia consumes 48% of the world’s whisky. It is the fastest-growing market and the largest producer of the spirit. But what exactly are we making and drinking?
Whisky is decidedly the spirit of choice in India—we consume almost half the whisky produced worldwide. From the cheapest Indian-made foreign liquor (IMFL) variant—whisky makes for almost 90% of IMFL—to limited-edition single-malt Scotch, people are drinking more whisky today than ever, spending anywhere between Rs50 per 25ml peg for a McDowell’s at a Paharganj bar in Delhi to Rs1,500 for a small Johnnie Walker Blue Label at a five-star hotel. While gin is going through something of a resurgence, it is still whisky that racks up the numbers, with a more-than-healthy lead over every other alcoholic beverage.
Whisky, in the classical understanding, is an alcoholic beverage made from fermented grain mash. These grains—barley, maize, wheat, rye, etc.—are malted and fermented, and can be used in various combinations or on their own to make whisky.
Ground malted barley is soaked in warm water to extract sugars. The sweet liquor called wort is drained and transferred to fermentation tanks. Yeast is added to this to break down the sugars to alcohol. The fermentation results in a liquid called wash, which is then distilled. Most companies distil the liquid twice but sometimes it is distilled thrice. The distilled whisky is then stored in wooden barrels for maturation.
In India, most of the whisky is made from molasses—the dark, viscous by-product obtained by refining sugar from sugarcane. Fermented molasses are boiled to extract alcohol, which is distilled. The distillation results in a neutral spirit with 96% alcohol by volume, which forms the base of all IMFL. This is blended with a small amount of Scotch for flavour, and voila, we have Indian-made whisky.
“The major difference between the molasses-based and grains-based whisky is at the distillation stage,” says Nikam of Amrut, which makes both kinds of whiskies. “When we use the molasses base, we distil the alcohol till it becomes neutral and doesn’t have any characteristic flavour. For grains, we do an incomplete distillation so part of the flavour from the grains is there before it goes into barrels to mature.”
Amrut, which was established by Radhakrishna Jagdale in 1948, produces spirits from vodka to gin, including Amrut single malt whisky, which is exported to more than 25 countries.
According to Nikam, Amrut produces about 6 million nine-litre cases of liquor annually, 35,000 of which are single malt whisky. The company exports at least 60% of its single malts. As the company tries to expand beyond its key southern markets, Amrut is planning to increase its single malt production to 100,000 cases by 2022, half of which Nikam hopes will be consumed in India.
Globally, making whisky is a strictly regulated business. For example, in 2008, Europe passed a directive asserting that whisky was an alcoholic drink produced exclusively by the distillation of a mash made from malted cereals. This immediately excludes most “Indian whiskies” from the category.
Scotland took this a step further the next year, introducing the Scotch Whisky Regulations 2009 (SWR). The new regulations gave the precise definition of different kinds of whisky and the difference between a single grain and a single malt. The document has stringent guidelines on regional and geographical indications, production and maturation of Scotch. According to the SWR, Scotch can’t be made or matured outside Scotland. For a whisky to be called Scotch, it has to be made in Scotland, with set raw materials, and has to be aged within the country for three years or more.
Much of the whisky-producing world—from the US to Japan and Australia—has stuck to similar guidelines regarding the product and its manufacturing process. American bourbon whiskey, for example, must mature in new oak barrels, which are then used to age Scotch. In India, however, there are multiple regulations governing consumption age, on obtaining liquor licences and the tax structure—leading to arbitrary and exorbitant prices. But there are hardly any rules that benefit the end user, such as differentiating whisky from rum, or even country liquor for that matter.
The only stricture, according to a 2005 Bureau of Indian Standards publication, is that whisky should be made either from a neutral spirit that matches its standards, or a Grade I rectified spirit, or a mix of both. It is this laxity on the part of the Bureau of Indian Standards that allows for so many different spirits, many of which are artificially coloured, to be bottled and legally sold as whisky.
Yet last year, for the first time, the Union government standardized alcohol as a consumable product beyond tax purposes, and the Food Safety and Standards Authority of India (FSSAI) came up with the draft Food Safety and Standards (Alcoholic Beverages Standards) Regulations, 2016, which defined various kinds of alcohol and their types.
According to the draft, “Whisky is an alcoholic beverage made from neutral grain spirit or rectified grain spirit, or neutral spirit or their mixture or is made by distilling the fermented extract of malted cereal grains such as corn, rye, barley; or molasses.”
At the same time, both rum and country liquor are defined by the FSSAI in pretty much the same way. Going by this definition, it’s hard to establish the difference between these three kinds of alcohol.
ost whisky made in India is aged briefly because the higher temperatures result in quicker evaporation of the spirit during the maturation stage, a phenomenon known as “the angels’ share”. The draft regulations require that whiskies in India, when labelled matured, “shall be matured for a period of not less than one year in wooden oak, wooden vats or barrels”. This means that much of the whisky that falls in the IMFL category is not aged at all.
Understandably, there has been retaliation, mostly in Europe, against the rise of India-made “cheap whiskies”. In its 2013 annual report, the Scotch Whisky Association (SWA) urged European Union-wide action against the “extremely worrying” quantities of cheap Indian blends being imported into the EU.
“There is no compulsory definition of whisky in India, and the Indian voluntary standard does not require whisky to be distilled from cereals or to be matured,” according to a 2014 PTIreport which quoted the SWA report. “Very little Indian ‘whisky’ qualifies as whisky in the EU owing to the use of molasses or neutral alcohol, limited maturation (if any) and the use of flavourings. Such spirits are, of course, considerably cheaper to produce than genuine whisky.”
Whisky distillation came to India with the British in the 19th century. Edward Dyer, father of Reginald Dyer, the infamous British colonel who ordered the Jallianwala Bagh massacre, was the pioneer of whisky-making in India. Dyer senior set up a distillery in Kasauli in the 1820s. Kasauli, in the Himalayan highlands at 6,000ft above sea level, has climate similar to Scotland, with the added advantage that there was fresh springwater nearby. The distillery later moved to Solan.
Dyer brought equipment and copper stills from Scotland, some of which are still in use. The distillery’s Solan No.1 was the best-selling whisky in India for over a century but today, the only malt whisky from the Himalayas is struggling to find takers.
How molasses took over grains is actually quite an interesting story.
Across the world, people use agricultural surplus to make alcohol. Barley in Scotland; wheat, corn and rye in the US; rice in some Asian countries; and sugarcane in India. This is why molasses became prominent in Indian alcohol production.
In 1947, entrepreneur Vittal Mallya bought United Breweries, a group of five breweries in south India that made beer for British troops. At one time, United Spirits Ltd, the group’s alcoholic beverages company, was the largest spirit producer in India, with around 60% of the market share. Its brands included locally produced Bagpiper, Royal Challenge, McDowell’s No.1, and Antiquity, Jura and Dalmore single malt Scotch whiskies.
Diageo Plc., the world’s largest producer of spirits, now owns USL and the business is now called Diageo India.
“Diageo India is a market leader in both Scotch and IMFL segments and our brands are all available at distinctive price points in the overall whisky category,” says Thomas. “With each brand attracting a different set of consumers driven by varying taste preferences and affordability, we see sufficient interest across all the segments.”
But if you want to reach the masses, pricing your product at Rs300 per 750ml bottle, it simply isn’t possible to make it with grains, says Nikam. “At that price point, the product can only be made from neutral spirits,” he says.
Entry-level whisky is the most volatile space of the market. “Those people who were consuming country liquor will slowly move up to entry-level IMFL,” says Nikam.
“If you take the whiskies in the Rs300 price range and change the price by Rs5, you’d suddenly gain or lose 50% of your market share,” says drinks consultant Anand Virmani. “Frankly speaking, at that range, you can’t really make a good whisky.”
But consumers are upgrading as a result of increased exposure, better knowledge and more disposable income. Brands are taking notice. “Several brands in the Rs600-800 range have repackaged themselves,” says Virmani. “Many now have a limited edition kind of product too in the mix. It is an evolving market.”
IMFL has its place. “It is okay in the context in which it is being consumed,” says London-based whisky writer Joel Harrison. “Even though it isn’t the drink of the connoisseur, it is sweet and accessible, and can be easily consumed neat or mixed into a long drink.”
“There’s been significant improvement in the distillation technology and, therefore, even the alcohol made from molasses in most cases is of extremely good quality and does not make much of a quality difference,” says Sridhar Pongur, joint managing director at Goa-based John Distilleries Pvt. Ltd, which makes the Paul John brand of single malt whiskies. “However, since maturation is not normally done in India, there is definitely a difference in taste and flavour.”

Why wind energy?

Why wind energy?

The project is environment friendly.
India has good wind potential to harness wind energy.
A permanent shield against ever increasing power prices. The cost per kwh reduces over a period of time as against rising cost for conventional power projects.
The cheapest source of electrical energy. (on a levelled cost over 20 years.)
Least equity participation required, as well as low cost debt is easily available to wind energy projects.
A project with the fastest payback period.
A real fast track power project, with the lowest gestation period; and a modular concept.
Operation and Maintenance (O&M) costs are low.
No marketing risks, as the product is electrical energy.
A project with no investment in manpower.
A country like India or any region where energy production is based on imported coal or oil will become more self-sufficient by using alternatives such as wind power. Electricity produced from the wind produces no CO2 emissions and therefore does not contribute to the greenhouse effect. Wind energy is relatively labour intensive and thus creates many jobs. In remote areas or areas with a weak grid, wind energy can be used for charging batteries or can be combined with a diesel engine to save fuel whenever wind is available. At windy sites the price of electricity, measured in Rs/kWh, is competitive with the production price from more conventional methods, for example coal fired power plants.

Limitations
Wind machines must be located where strong, dependable winds are available most of the time.
Because winds do not blow strongly enough to produce power all the time, energy from wind machines is considered "intermittent," that is, it comes and goes. Therefore, electricity from wind machines must have a back-up supply from another source.
As wind power is "intermittent," utility companies can use it for only part of their total energy needs.
Wind towers and turbine blades are subject to damage from high winds and lighting. Rotating parts, which are located high off the ground can be difficult and expensive to repair.
Electricity produced by wind power sometimes fluctuates in voltage and power factor, which can cause difficulties in linking its power to a utility system.
The noise made by rotating wind machine blades can be annoying to nearby neighbors.
People have complained about aesthetics of and avian mortality from wind machines.

Biofuels

Biofuels are liquid or gaseous fuels primarily produced from biomass, and can be used to replace or can be used in addition to diesel, petrol or other fossil fuels for transport, stationary, portable and other applications. Crops used to make biofuels are generally either high in sugar (such as sugarcane, sugarbeet, and sweet sorghum), starch (such as maize and tapioca) or oils (such as soybean, rapeseed, coconut, sunflower).

Categories of biofuels

Biofuels are generally classified into three categories. They are
  1. First generation biofuels - First-generation biofuels are made from sugar, starch, vegetable oil, or animal fats using conventional technology. Common first-generation biofuels include Bioalcohols, Biodiesel, Vegetable oil, Bioethers, Biogas.
  2. Second generation biofuels - These are produced from non-food crops, such as cellulosic biofuels and waste biomass (stalks of wheat and corn, and wood). Examples include advanced biofuels like biohydrogen, biomethanol.
  3. Third generation biofuels - These are produced from micro-organisms like algae.

Biodiesel and its benefits

Bio-diesel is an eco-friendly, alternative diesel fuel prepared from domestic renewable resources ie. vegetable oils (edible or non- edible oil) and animal fats. These natural oils and fats are primarily made up of triglycerides. These triglycerides when reacted chemically with lower alcohols in presence of a catalyst result in fatty acid esters. These esters show striking similarity to petroleum derived diesel and are called "Biodiesel". As India is deficient in edible oils, non-edible oil may be material of choice for producing biodiesel. Examples are Jatropha curcas, Pongamia, Karanja, etc.
The benefits of using biodiesel are as follows
  • It reduce vehicle emission which makes it eco-friendly.
  • It is made from renewable sources and can be prepared locally.
  • Increases engine performance because it has higher cetane numbers as compared to petro diesel.
  • It has excellent lubricity.
  • Increased safety in storage and transport because the fuel is nontoxic and bio degradable (Storage, high flash pt)
  • Production of bio diesel in India will reduce dependence on foreign suppliers, thus helpful in price stability.
  • Reduction of greenhouse gases at least by 3.3 kg COequivalent per kg of biodiesel.

Biofuels

Jatropha

Jatropha curcas is multi purpose non edible oil yielding perennial shrub. This is a hardy and drought tolerant crop can be raised in marginal lands with lesser input. The crop can be maintained for 30 years economically.

Sorghum

Sorghum (S. bicolor) is the most important millet crop occupying largest area among the cereals next to rice. It is mainly grown for its grain and fodder. Alternative uses of sorghum include commercial utilization of grain in food industry and utilization of stalk for the production of value-added products like ethanol, syrup and jaggery and bioenriched bagasse as a fodder and as a base material for cogeneration.

Pongamia

There is several non edible oil yielding trees that can be grown to produce biofuel. Karanja (Pongamia) is one of the most suitable trees. It is widely grown in various parts of the country.
Salient features of Pongamia
  • It is a Nitrogen fixing tree and hence enriches the soil fertility
  • It is generally not grazed by animals
  • It is tolerant to water logging, saline and alkaline soils,
  • It can withstand harsh climates (medium to high rainfall).
  • It can be planted on degraded, waste/fallow and cultivable lands
  • Pongamiaseeds contain 30-40% oil.
  • It helps in controlling soil erosion and binding sand dunes, because of its dense network of lateral roots.
  • Its root, bark, leaves, sap, and flower have medicinal properties. Dried leaves are used as an insect repellent in stored grains.
Properties of Pongamia Oil
  • Non edible oil is largely extracted from seeds.
  • The collected seeds consist of 95% kernel
  • The oil content varies between 27 - 40%.
  • When mechanical expellers are used for recovery of oil from the kernels, the yield of oil is reported to be about 24 to 26.5%
  • The crude oil is yellow orange to brown in color, which deepens on standing. It has a bitter taste, disagreeable odour, and it’s non-edible.
  • Apart from use as a biofuel, the oil can be used for lighting lamps, lubricant, water-paint binder, pesticide, and in soap making and tanning industries
  • The oil is known to be used for the treatment of rheumatism and human and animal skin diseases.
  • The press cake (left over after oil extraction) is rich in Nitrogen and hence can be used for improving soil fertility. The press cake when applied to the soil, also has pesticidal value, particularly against nematodes.
Pongamia seed oil Vs standard petroleum/diesel

  • Pongamia seed oil as a bio- fuel has physical properties very similar to conventional diesel.
  • It is, however a clean fuel (eco friendly) than conventional diesel
