Biogorivo lignocelulozne sirovine
Major energy provider (80%) for current economy and lifestyle are fossil fuels. Transport sector, a major consumer of petroleum fuels (diesel, gasoline, liquid petroleum gas and compressed natural gas, is likely to suffer badly because oil re-serves are decreasing, and therefore, there is a continuous rise of crude oil prices. Fossil fuels emit greenhouse gases (CO2, CH4 and CO) resulting in global warming and pollution. Intensive research is going on to generate clean and sustainable energy sources from renewable carbon resources. Biofuels represent ecofriendly, biodegradable, sustainable, cost competitive and promising alternative energy source for fossil fuels. The primary motivation for the development of biofuels is decreasing dependence from fossil fuels import in some countries and it is not re-duce CO2 emissions. This paper reviews methods for obtain biofuels from lignocellulosic feedstock and technologies.
