Energy
Biomass refers to all the matter that can be obtained from photosynthesis. Most vegetable species use solar energy to create sugars from carbon dioxide and water. They store this energy in the form of glucose or starch molecules, oleaginous, cellulose, and lignocellulose .Biomass appears to be an attractive feedstock for three main reasons. First, it is a renewable resource that could be sustain ably developed in the future. Second, it appears to have formidably positive environmental properties, notably the recycling of carbon in the biological processes, resulting in no net releases of…
Present study was aimed to increase latex yield in Euphorbia antisyphilitica. It was observed that GA3 supported maximum above ground plant height and fresh weight and biomass yield of the plant while the auxins (NAA and IAA) promoted growth and biomass yield over control and the hexane extractables and concluded that the application of growth regulators on Euphorbia antisyphilitica is beneficial to obtain raw material.

ABSTRACT : Calotropis procera is a potential plant for bioenergy and biofuel production in semi arid regions of the country. At the global level, according to recent estimates by FAO the annual tropical deforestation rate for the decade 1981 to 1990 was about 15.4 million…
While delivering a lecture at Centre for community economics and development consultants society Jaipur (www.cecbedecon.org) the orgniser Dr Alka Avasthi and participants posed some interesting questions which need answer.Can Jatropha be grown on the sandy soils. What is its water requirement available and realtime, its nutrient requirement, pest management, and yield potential in areas other than its habit and habitat. Are there some non toxic strains available . Some of these questions need answers from experts around the globe and replies and iteractions are welcome.
Vegetable oils can be chemically reacted with an alcohol (methanol is the usual choice) to produce chemical compounds known as esters. Biodiesel is the name given to these esters when they are intended for use as fuel.
India imported about 2/3rd of its petroleum requirements last year, which involved a cost of approximately Rs. 80,000 crores in foreign exchange. Even 5% replacement of petroleum fuel by bio-fuel can help India save Rs.4000 crores per year in foreign exchange.
It is important that the options for substitution of petroleum fuels be explored to control this burgeoning import…
A large number of plants around the world are unexplored Some of which could sereve as bioenergy plants and still have medicinal value. Let us compile the world list of such plants from each regions. This would explore new possibilities of developing biomass resources and help in keeping our enviornment intact for our future generations.
Solid biomass.
The characterization of plant diversity was another aspect of study on plant community. 230 plant species were recorded. Out of the 230 plant species 60 plant species were selected for biomass production in their natural habitat.…

ABSTRACT:
In Rajasthan, Jatropha grows wild in south east Rajasthan which lies on south east side of Aravalli hill range which roughly divides the state in semi-arid and arid regions. A detailed survey was carried out in these areas. Nursery techniques for large scale plantation of elite…
Biodiesel
There is nothing to stop biodiesel making an immediate impact in reducing the world's dependence on fossil fuels that contribute to global warming. Using biodiesel requires no major changes to either existing diesel engines or to the current distribution infrastructure of storage tanks and petrol stations that delivers diesel fuel to consumers.
Petroleum diesel produces high levels of carbon dioxide (CO2), a greenhouse gas that contributes significantly to global warming. But burning biodiesel produces only a marginal increase in CO2 emissions, because the crops from which it is…
Worldwide energy consumption is projected to grow by 59 percent over the next two decades, according to International Energy Outlook 2001 (IEO 2001), released by US Energy Information Administration EIA. One half of the projected growth is expected to occur in the developing nations of Asia ( Including China, India and South Korea) and in Central and South America, where strong economic growth is likely to spur demand for energy over the forecast period. Renewable energy use is expected to increase by 53 percent between 1999 and 2020, but its current 9 percent share of…
The Jatropha plant or shrub like tree can grow in a wide variety of climates. Its seeds contain about 40% oil that can be extracted for energy as feedstock for renewable biodiesel production. Currently, the early stage Jatropha emerging market is growing at 18% annually. This promising biofuel feedstock receives about $600 million invested annually in targeted Jatropha developments.
Today, there are 242 Jatropha cultivation projects worldwide totaling roughly 930,000 hectares. The plantation production capacity is rapidly growing and should reach 13 million hectares exceeding well over $1…
