Acronym – Refuse Derived Fuel -recycled municipal solid waste, which has been processed prior to combustion to increase the calorific value of the waste. It is produced by mechanically removing the non-combustible materials such as metal and glass and then processing the remaining waste into coarse (c-RDF) or densified RDF (d-RDF) pellet or briquette.
