Raw materials for biomass pellets include wood residues (sawdust, wood chips, bark, branches), agricultural residues (straw, rice husks, corn stalks, sugarcane bagasse, cotton stalks, nut shells), and certain types of municipal solid waste (cardboard, waste paper). These materials are compressed under high pressure into dense, uniformly shaped pellets, which serve as a renewable fuel source.
