What does the incineration process convert sludge into?

The incineration process primarily converts sludge into inert ash, which is the solid residue remaining after the combustion of organic material. During incineration, the high temperatures effectively destroy the organic components of the sludge, resulting in the reduction of volume and the transformation of materials into ash and gases. The inert ash produced is typically composed of non-combustible minerals and serves as a relatively stable final product. This process helps to minimize the amount of waste that needs to be managed in landfills and can also reduce the risks associated with pathogens and odors often present in untreated sludge. Thus, the conversion of sludge into inert ash is a key aspect of waste management in wastewater treatment and contributes to overall environmental sustainability.
