Description

Porcelain recycling rate in Japan is low today because of the limited amounts and various kinds of recyclable porcelain. Companies in some porcelain producing districts have tried to develop processes that use recycle crushed porcelain. However, assessment of the environmental and economic aspects of recycling porcelain is inadequate. The objectives of this study were to assess the environmental load and production efficiency of the production system for the “Re-Seto” porcelain recycling facility, which is located in Seto city, Aichi prefecture. The environmental load was evaluated by performing a life cycle analysis (LCA), and production efficiency was evaluated by conducting a material flow cost accounting (MFCA). The results of an integrated MFCA-LCA evaluation showed that, for soil-made processes, the MFCA value decreased by 20% and the LIME value decreased by 9.2%. For the porcelain production process, the MFCA value decreased by 1.0% and the LIME value decreased by 8.6%. It therefore follows that a porcelain recycling and production system can be effective in terms of production efficiency and environmental load reduction.
