What are the different plant materials used as biofuel?

Various plant materials are used as biofuels, including agricultural residues like corn stover and wheat straw, dedicated energy crops such as switchgrass and miscanthus, and oilseeds like soybeans and canola for biodiesel production. Additionally, organic waste from food processing and forestry, such as wood chips and sawdust, can be converted into biofuels. Algae is also gaining attention for its potential to produce biofuels due to its high oil content and rapid growth rates. These materials can be processed into bioethanol, biodiesel, and other biofuel forms.
