Soybean straw is a lignocellulosic agricultural stalk. It’s plentiful, inexpensive, and a renewable resource. Over 16 million

but most of soybean straw is arbitrarily discarded or set on fire.
These disposals must result in resource loss and environmental
pollution. The exploitation and utilization of soybean straw must
bring obvious economic and social benefit to mankind
