However, because the WTE incineration process burns materials to create energy, ash is produced as a by-product. In general, the residual incineration ash is approximately 10% the volume of the input waste and 30% its mass (as the ash tends to be denser than the original material). Thus, WTE incineration, while sustainable in the sense that it ...
