Phosphorus Behavior during Supercritical Water Gasification of Sewage Sludge

T. Yanagida, Y. Unami, M. Kanna & Y. Matsumura
Supercritical water gasification (SCWG) is a potential new technology for wet biomass such as sewage sludge, livestock manure, and it can quickly and efficiently convert organic materials in the feedstock into fuel gases. Sewage sludge mainly comprises organisms and microbes which contents phosphorus (P). In Japan, almost all phosphorus as phosphate rock is imported from China, Morocco, South Africa and Jordan. Therefore, the recovery and reuse of P from sewage sludge is important. However little...
