Abstract

Over 50% of the approximately twenty million tons of food waste generated annually in Japan comes from kitchens and the food industry and is a type of municipal food waste which is difficult to recycle. Here we propose a novel recycling system for municipal food waste which combines fermentation and chemical processes to produce recyclable plastics from high quality poly-L-lactic acid (PLLA) . The total design of the process allows for a high yield of PLLA with high optical activity and novel recycling of all materials produced at each step, with minimal emissions and energy-savings.<BR>Evaluation of the system is discussed from the standpoints of energy balances, environmental impact, as well as sustainability of the industry, which are all important areas to consider for the establishment of a recycling-based society.
