Refuse-derived fuel (RDF) generally refers to the product of the mechanical (or chemical plus mechanical) processing of municipal solid waste (MSW) to produce a specification output. Densified refuse-derived fuel (d-RDF) is the product of the mechanical compaction of some form of RDF to agglomerated pieces which are sufficiently cohesive to sustain storage and handling. The term densified is used in the generic sense to include all forms of compaction, such as extrusion or rolling to produce briquettes, pellets, cubettes, etc. Generally, d-RDF is a fuel for stoker boilers analogous to lump coal. The concept of RDF and d-RDF can be extended to other waste-derived or biomass fuels. The pilot-scale preparation of d-RDF has been described. This paper is to update and expand the information and to describe the objectives and operation of some of the unit processes used and the properties of the d-RDF. It should be an objective of processing to maximize the quality of the fuel, even at the expense of quantity, so as to maintain the fuel specification. Thus, a mass of waste, m, is converted to a mass of fuel, m', so that m > m', but the heats of combustion are ..delta..H/sub m/ < ..delta..H/sub m'/, which is the objective of processing. The yield is limited by the composition of m and the limits of the law of conservation of mass-energy; also, allowance must be made for the energy input for processing. The concept of processing to maximize yield is opposite to the traditional objective of waste management of maximizing disposal.
