A type of conversion technology that turns organic wastes into usable products. Thermochemical conversion processes include combustion, gasification, and pyrolysis. Thermochemical conversion is characterized by higher temperatures and faster conversion rates. It is best suited for lower moisture feedstocks. Thermochemical routes can convert all of the organic portion of suitable feedstocks. The inorganic ash of a feedstock does not contribute to the energy products but may contribute to fouling of high temperature equipment, increased nutrient loading in wastewater treatment and disposal facilities, and in some cases by providing marketable coproducts or adding disposal cost.
