Since the 1980s, waste combustion has developed at the expense of landfilling, but it has some drawbacks with the formation and release into the atmosphere of fly ash containing heavy metals, soot, sulfur and nitrogen oxides, chlorinated compounds, dioxins and also large quantities of CO ₂ . The resulting slags also contain hydrogen and polyaromatics. This technique, in order to meet increasingly stringent environmental standards, involves costly filtering...
