Analysis on Consciousness for Utilization of Energy Derived fromSewage Sludge in Sewage Treatment Secotors

Abstract

In this paper, awareness, consciousness and acceptance were analyzed for sludge-derived energy utilization by a questionnaire survey to sewage treatment sectors. As a result of the survey, it was revealed that: almost half of sewage works agree to utilize sludge as energy resources; value of the sludge as a fuel is estimated around 1,100 yen per a ton of dewatered sludge; large sewage works showrelatively defined acceptance of using sewage sludge fuel.
