Biofuels are a type of renewable fuel that is derived from biomass, often plant matter or another kind of biological material. They are used to partially or completely replace petroleum-derived fossil fuels. Kinds of biofuels include solid biomass, liquid fuels and biogases. Specific examples include bioethanol, made from sugar and starch crops, and biodiesel, made from vegetable oils, animals fats and other recycled greases.
The food production giant is exploring how the waste in its operations -- namely inedible fats and greases -- could become a source of renewable energy.
