Clinker is the residue produced from the incineration of household waste, as well as the combustion of coal and coke. It represents 20 to 25% of the initial weight and 10% of the incinerated volume.
Clinker, also called HRIC (Household Refuse Incineration Clinker) consists of ferrous and non-ferrous metals, minerals such as silica, glass, or calcium and organic compounds.
This waste can be recycled to produce steel, aluminium or aggregates for building and civil engineering.
