Recently, we have been facing with the environmental problems. So the social system must be transformed to a sustainable cycle-oriented social system immediately. A considerable number of studies has been conducted on environmental problems. However, those studies focused on optimizing the material flow and did not focus on the consumer's behavior. In this paper, we discuss the consumer's value creation. By the consumer's value creation, we believe that we can form the sustainable cycle-oriented social system. In this paper, therefore, we show the database, which helps the consumers to do the value creation, and we inspect our belief by means of a computer simulation.
