The life cycle of a polypropylene stacking chair is assessed in order to represent the environmental impact of a plastic product. The analysis is categorized into two phases, manufacturing and disposing. The manufacturing process of a chair concerns a prime material, polypropylene (PP) granulate, an injection molding process and a resource, electricity. According to the assessment, the PP granulate seems to contribute the highest impact on the environment in term of the fossil fuel used. Afterwards, the landfill method is used in the disposal scenario of waste, and the analysis shows that the highest impact comes in the form of carcinogens followed by ecotoxicity.

Full mold casting is a casting process in which a mold made of wood or metal is substituted for a styrofoam model. This metal casting process is advantageous for the production of large-sized castings because it uses a foamed model. However, this unique process of melting a foamed model causes a problem which is the foamed model remains dissolved in the casting. This is called foam residue defect and is specific to full mold casting. In this study, we propose a new casting design called a residue trap to reduce these residue defects. This residue trap collects the residue of foam models included in the molten metal, which tends to be generated when the temperature of the molten metal becomes low by being attached to the product part in the same way to overflows. We also optimized the shape of the residue trap in terms of easing of post-treatment and increasing efficiency of collecting foam residue. Eventually, the effectiveness of the residue trap was verified by actual full mold casting experiments.
