Abstract

With the advancement of technologies and sustainability awareness, sustainable manufacturing has formed a trend and transformation in manufacturing industry is becoming inevitable. In order to cope with the manufacturing transformation, this study proposes a collection-recycling-manufacturing (CRM) model to envision the process simulation as well as the process improvements. In this transformation, reduction of materials, cost, transportation and energy, and elimination of CO2 emission are the objectives, and innovation is the key to drive the solutions into a concrete foundation. By applying simulation techniques in the optimization of recycling facility management, this study produces generic formula in Materials Recycling Facilities (MRF) topology design and transportation distance calculation. The formula is expected to predict operation through an optimization of MRF counts at the cost of transportation, energy consumption, and CO2 emission. This study also proposes solutions to fill-in the gap of Additive Manufacturing (AM) before becoming the industry mainstream. This study suggests an expansion of materials recycling coverage, and take full advantages of AM to penetrate market. Meanwhile, it identifies AM limitations supported by enhancement plan to streamline the transformation and to support sustainable manufacturing.
