A: Most fibrous and powdered biomass and feed ingredients work: sawdust, wood chips, straw, rice husk, corn stalk, grass, peanut shells, soybean meal, and mixed feed formulas. Moisture control and pre-processing (chipping, hammer-milling, drying, mixing) are important — typically wood raw materials perform best at about 10–15% moisture and feed formulas around 12–18%.
