Using biogas to make vehicle fuel and city gas The government approved the proposal, called the Kobe Green/Sweets Project. The trial project comprises the production of renewable energy and use of innovative technology at Higashinada Sewage Treatment Plant. The aim of the current project is to turn the sewage treatment plant into a supply source for renewable energy. As well as taking in biomass from food ("sweets"), which is well suited to sewage, and wood ("green") to produce more biogas, the project will demonstrate that it is possible to reduce life cycle costs (LCC) and monitor operational status via a steel digestion tank fitted with sensors. The project aims to reduce LCC further by using a heat pump to heat the digestion tank and building in a bio-natural gas conversion system. The future of biogas starts now.
