Energy wastage or energy wastage is the process of generating energy in the form of electricity and / or heat from the primary treatment of waste. WtE is a form of energy recovery. Most WtE processes produce electricity and / or heat directly through combustion, or produce a combustible fuel such as methane, methanol, ethanol or synthetic fuels. Combustion of organic material as waste with energy recovery is the most common WtE implementation. All new WtE plants in OECD countries that incinerate waste (MSW residual, commercial, industrial or RDF) must meet stringent emission standards, including nitrogen oxides (NOx), sulfur dioxide, heavy metals and dioxins . Therefore, modern incineration plants are very different from the old ones, some of which did not recover energy or materials. Modern incinerators reduce the volume of the original waste by 95-96 percent, depending on the composition and degree of recovery of materials such as the metals from the ash to recycle them.
Incinerators can emit fine particles, heavy metals, traces of dioxins and acid gas, even though these emissions are relatively low from modern incinerators. Other concerns include proper handling of the waste: toxic fly ash, which must be handled at the hazardous waste disposal facility as well as incinerator bottom ash (IBA), which must be properly reused.
