Abstract

In order to reduce the environmental effect of recycling systems, the SLCA method (Service Life Cycle Assessment) was proved to be more effective than PLCA. In this paper, we outline the SLCAmethod when used with recycling systems and make clarify the differences between the PLCA and SLCA method. We made a case study in a city by using two recycling systems with the SLCA method. The results of our study showed that recycling systems (the method of classification, collection frequency, transporting distance) must be assessed from an environmental standpoint.

Key words: recycling system, recycling, SLCA, impact assessment, vessels
