Abstract

It is an environmental problem in the stadium where the sports event is held that a large amount of the paper cup is wasted along with sales of beverage such as beer and soft drinks. The returnable cup system has been carried out in Oita Big Eye for the reduction of waste and the effective use of resource. In this study, life cycle inventory of the returnable cup system in the stadium was analyzed, and the reduction effects of energy consumption and solid waste were investigated by comparing with the conventional bev-erage service using the paper cup.
As a result, it was shown that the amount of environmental loads became smaller in the beverage service by the server. In addition, it was confirmed to be able to decrease the amount of environmental loads in the beverage service with the returnable cup by increasing the number of reuse. Changing to the bever-age service with the returnable cup from the paper cup could largely reduce several environmental loads in Oita Big Eye. It was suggested that the reduction rate of environmental loads in one game was larger by changing from the beverage service by the aluminum can or the PET bottle to the server.
