WASTE TECHNOLOGIES: WASTE TO ENERGY FACILITIES

Combustion (incineration) of waste is achieved by heating waste in an excess of oxygen. 'Mass burn' refers to a process that accepts raw or post recycling municipal solid waste (MSW) without any additional pre-treatment (e.g. no shredding or refuse derived fuel (RDF) production). The process can best be explained by examination
