Abstract

Improvement of transport efficiency in reverse logistics contributes not only to direct efficiency gains but also to promotion of waste recycling. This paper first examines the existing situation of waste management and related reverse logistics systems in Japan. Some examples of efficient reverse logistics systems in the United States are also discussed. In considering the case of the Tokyo Prefecture area, alternative transport systems for waste management reverse logistics are evaluated using a vehicle routing model based upon a genetic algorithm. The modeling results show that the milk-run type cooperative truck transport in combination with bulk-hauling railway transport is the most cost-effective option with significant benefits in terms of lower CO2 emissions.
