A Review on Various Thermochemical Technologies for Resource Recovery from Sewage Sludge
Municipal sewage sludge (MSS) disposal is a major problem in different countries worldwide. Renewable energy recovery from waste is an efficient alternative to waste management options. Recovering energy from sludge increases resource efficiency as a renewable option and replaces fossil fuel in the long run. Using sewage sludge for production of energy will surely have a positive socio-economic effect. In the last few years, several efficient technologies have been invented for treating MSS and generalise energy. The objective of this study is to review different technologies of production of bioenergy from sewage sludge. Their utilisation in different Asian and European countries are shown and also to look into their supply chain sustainability is an important part of this area of work. The supply chain sustainability of these processes focusing on the operational and economical aspects is examined. An attempt at making these processes green is also studied. Finally, the paper gives a future research scope on cost-effectiveness and planning strategies in the technologies used. Very few reviews have been done on this topic. The work has great importance towards environmental and economical aspect.
