Waste incineration is defined as the combustion of solid and liquid waste in controlled incineration facilities.
Modern refuse combustors have tall stacks and specially designed combustion chambers, which provide high
combustion temperatures, long residence times, and efficient waste agitation while introducing air for more
complete combustion. Types of waste incinerated include municipal solid waste (MSW), industrial waste,
hazardous waste, clinical waste and sewage sludge1. The practice of MSW incineration is currently more
common in developed countries, while it is common for both developed and developing countries to incinerate
clinical waste.
