The principles of solid waste handling include many methods, such as incineration, sanitary landfills,
and municipal waste composting. However, incineration and sanitary landfills have adverse
environmental impacts. Thus, nowadays the focus of solid waste handling is to reduce the quantity of solid wastes. Composting of municipal waste is a widely used method, but it involves the subsequent
handling of rejected material. The rejected material consists of a large amount of resistant organic matter
that cannot be transformed in the composting process and must be disposed of. Therefore, if it can be
utilized to produce beneficial things such as solid fuel briquettes[1], it will significantly reduce
unnecessary use of landfills.
