Biofuel is all about trash! To make Biofuel you have to burn all you trash into a fuel, then contain it so you can use it so you don't waste our precious resources. The cool thing about Biofuel is that you don't just throw away your trash you use it for some thing you can use for the better.
A biofuel is a fuel that is produced through contemporary biological processes, such as agriculture and anaerobic digestion, rather than a fuel produced by geological processes such as those involved in the formation of fossil fuels, such as coal and petroleum, from prehistoric biological matter. Biofuels can be derived directly from plants, or indirectly from agricultural, commercial, domestic, and/or industrial wastes.
