Although several uses for spent solid residue from solid-state fermentation (SSF) waste management systems have been proposed, treatment of the residue has not been studied thoroughly. Ensilage of solid-waste products is an acceptable treatment method used by other systems and was studied on a SSF system. Spent solids were obtained from a pilot plant, using SSF to produce cellulase with Trichoderma harzianum. After enzyme removal, the substrate dry-matter (SDM) content of the remainder was adjusted to about 33 or 45% before being sealed in plastic bags for six months. The higher SDM content silage was of poor quality because of highly volatile fatty acid levels. Use of additives decreased the SDM contents slightly. The best-quality silage was obtained with the higher initial SDM (43%) and 0.3% ensiling additive.
