|Title:||Prospects of biofuels production and pollution control from crop residues|
Joshi, H C

|Abstract:||Unsustainable utilization of natural resources, increasing human exploitation and industrial activities, accelerate the pollution rate and climatechange that are arising as major problems on global scenario. Vehicular and industrial activity depends upon 75% imported petroleum that isgrowing with 5-6% annual rate, is directly responsible for the increasing pollution level, global warming and heavy burden on nationaleconomy. According to an estimation the energy demand can be fulfilled by the renewable energy sources likewise- biofuels, hydro, solar,wind energy and geothermal energy. Biofuels are most prevalent substitute of fossil fuels because biofuels are responsible for less pollution,green house gas emission besides their eco-friendly nature, thus globally much research being continued. Among the second generation biofuelsources, lingo-cellulosic material mainly, crop residue (straw, leaves and stalk) and other different biogenic residues that are obtained from theprocessing units can be utilized for the generation of biofuels viz., bioethanol, methane and biohydrogen etc. for transport and industrialapplications which are very beneficial from environmental point of view. Biofuels generation from crop residues does not impose any dangerfor the food security. Alternative fuels from the crop residues have enormous opportunities for pollution abatement. For instance, bioethanolis an oxygenated fuel that contains 37% oxygen by weight that helps in complete combustion; produces less harmful gases during, thereforehelpful in pollution control. Alternative biofuels from crop residues can be capable in the generation of least pollution, energy dependency,holistic utilization of resources, minimum environmental loss and in keeping balance with environment.|
