STRATEGIES FOR BIOFUEL PRODUCTION AND IMPROVEMENT IN DEVELOPING COUNTRIES: PROBLEMS AND PROSPECTS. A. Kumar Energy Plantation Demonstration project and Biotechnology Center. Bio-Technology Lab Department of Botany University of Rajasthan, Jaipur - 302 004 Email. msku31@yahoo.com ABSTRACT: A large number of hydrocarbon yielding plants like Calotropis procera, Euphorbia antisyphilitica have been reported to yield bio-fuel products. Attempts have been made to increase their growth and hydrocarbon yield potential. Studies were conducted to improve growth and productivity of these plants under…

PRODUCTIVTY OF CALOTROPIS PROCERA IN SEMI-ARID REGIONS OF RAJASTHAN AND ITS USE AS RENEWABLE SOURCE OF ENERGY Ashwani Kumar, V.R. Kumar Energy Plantation Demonstration project and Biotechnology Center. Department of Botany, University of Rajasthan, Jaipur – 302004, India. E-mail: msku31@yahoo.com ABSTRACT India has over 180 million of wasteland out of which 90 million ha is uncultivable. The degraded and denuded lands arise due to soil erosions as well as secondary salinizations. However Calotropis procera is a potential plant for bioenergy and biofuel production in semi arid regions of the…

Liquid biofuel support program launched in 1993 in France is implemented through tax exemptions to biofuels produced by agroindustrial chains. Activity levels are fixed by decree and allocated by the government to the different chains. Based on earmarked budget increase voted in the parliament, total quantity of biofuels will be increased by 50% in the horizon 2002–2003. A microeconomic biofuel activity model containing a detailed agricultural sector component, that is represented by 700 farms, is used to estimate costs and surpluses generated by the activity at the national level as well as…

SOME POTENTIAL PLANTS FOR BIO-ENERGY.   ASHWANI KUMAR AND AMIT KOTIYA Bio-Technology Lab,Department of Botany University of Rajasthan, Jaipur - 302 004 Engery Plantation Demonstration project and Biotechnology Center. Email. msku31@yahoo.com   ABSTRACT : India  has land  area of approximately 329 mha, out of which 150 mha of land area in India is uncultivable and around 90 mha. is characterized as wasteland. The arid region of India lies between 24° and 29° N latitude and 70° and 76° E longitude and covers 3,17,090 km2 area spread over seven states (Rajasthan,…

1.1 Biomass currently supplies about one third of the developing countries energy varying from about 90% in countries like Uganda, Rawanda and Tanzania, to 45 percent in India, 30 percent in China and Brazil and 10-15 percent in Mexico and South Africa mostly in traditional highly inefficient ways. Traditional uses of biomass in developing countries represents the bulk of energy; (900 to 1000 Mtoe, (38.42 EJ). The crucial questions are whether the two billion or more people who are now dependent on biomass for energy will increase. The fact that 90 percent of the worlds population will…

Jatropha curcus General introduction Jatropha is bush that grows in the warm regions of the world as it is sensitive to colder climates. Once it’s planted it grows and produces nuts that contain oil within a few years, and produces these annually for up to 50 years. Climate requirement for the plant is as altitude: 0-500 meters above sea level. mild-annual temperature: 20-28 °C.annual rainfall: 300-1000 mm., or more. Jatropha has been grown in developing countries for many years it’s been used locally for production of oil that was used in local village based industries for soap production.…

A report examining the impact of biofuels on greenhouse gas emissions during the 21st century has found that carbon loss stemming from the displacement of food crops and pastures for biofuels crops may be twice as much as the CO2 emissions from land dedicated to biofuels production. The Science Express study also predicts that increased fertilizer use for biofuels production will cause nitrous oxide emissions (N2O) to become more important than carbon losses, in terms of warming potential, by the end of the century.  Using a global modeling system that links economic and biogeochemistry…

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 produced…

The state of Rajasthan is situated between 23°3’N and 30°12’ N latitude and 69°30’ and 78°17’ E longitude. The total land area of the state is about 3,42,239 km2, out of which about 1,96,150 km2 is arid and rest is semi-arid. This arid and semi-arid wasteland is rich in biodiversity. During present investigation studies were conducted on characterization of bio-energy resources in the semi arid region of Rajasthan. 230 plants species were characterized and out of them 60 plant species were selected for dry matter production, 11 plants were characterized for non-edible oil production and 13…

        Growth and productivity of Jatropha curcas under semi arid conditions . ASHWANI KUMAR Engery Plantation Demonstration project and Biotechnology Center. Bio-Technology Lab Department of Botany University of Rajasthan, Jaipur - 302 004 Email. msku31@yahoo.com     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…
