Waste-based ethanol production and a sound material-cycle society -Case studies on construction and food wastes in Japan-

This paper examines whether waste-based ethanol production can contribute to the realisation of a sound material-cycle society and what facilitates and hinders the implementation, based on two case studies conducted in Japan. Each of the selected projects is recognised as being the first projects of its kind in the world: ethanol production from construction waste timber and from food waste. Based on the analyses, policy implications are drown on how to utilise biofuels towards a sound material-cycle society.
