Incineration is a waste treatment process that involves the combustion of substances contained in waste materials. Industrial plants for waste incineration are commonly referred to as wastetoenergy facilities. Incineration and other hightemperature waste treatment systems are described as "thermal treatment".Incineration of waste materials converts the waste into ash, flue gas and heat.

Ferrock is made by combining steel dust waste with silica. A chemical reaction between the iron in the dust and the carbon dioxide in the air causes the mixture to turn into iron carbonate. Once this is mixed with water and exposed to carbon dioxide, it hardens into a solid form, similar to concrete. In this article, we will discuss the process ...
