Which raw material is used to prepare bio-fuels?

Biofuels are primarily produced from biomass, which includes a variety of raw materials such as agricultural crops (like corn and sugarcane), vegetable oils (such as soy and palm oil), waste materials (like animal manure and food scraps), and dedicated energy crops (like switchgrass and miscanthus). These materials can be converted into biofuels through various processes, including fermentation and transesterification. The choice of raw material often depends on local availability, economic factors, and sustainability considerations.
