Abstract: With the recent changes in waste management policy across many EU countries, more and more efforts are now being made on wastes recycling and minimisation. In this paper, the effects of the changing compositions of wastes on the operation of incineration plants are addressed. CFD technique is used to simulate the incineration processes in grate systems and advanced mathematical models are employed. The incineration characteristics have been expressed as functions of the percentage of combustible materials in wastes taken away for recycling. To offset the deteriorated performance of incineration in some cases, alternative operation modes have been suggested and simulated.

Keywords: waste incineration; municipal solid waste; MSW; mathematical modelling; CFD; computational fluid dynamics; waste composition; waste management; simulation; recycling; burning rate; temperature profile; gas emissions; combustion efficiency.
