We calculated the amount of carbon dioxide emission and cost each case of different recover rate of PET bottle material recycling, reuse and not recycling. From a questionnaire, it was made clear citizens' acceptance intention degrees toward recycle and reuse PET bottle in order to evaluate citizens' intention about recycling PET. And, we carried out integrated evaluation of each PET bottle by the amount of carbon dioxide emission, cost and citizens' intention. As a result, material recycling is the best evaluation when recover rate is over 60%. If citizens' acceptance for reuse PET bottle becomes 90%, reuse is the best evaluation over the 50% recover rate.
