A Life Cycle Environmental Impacts Analysis of Porcelain Plates
摘要
Ceramic wares of various types, sizes, and shapes can be found in many homes. They are popularly used to serve food and drinks. Although they have been utilized for centuries, there is a need to assess their potential impacts on the environment. This study utilized the four steps ISO 14044 standard based Life Cycle Assessment process to evaluate the potential environmental impacts of a South African made white porcelain dining plate. Results of the LCA analysis showed that the greatest impact of porcelain plates is Global Warming (GWP), followed by acidification (AP) and then eutrophication (EP). This implies that porcelain plates have the potential to cause significant climate change, aquatic issues, and forest related environmental impacts. Furthermore, the analysis revealed a massive amount of energy and water consumption. Improvements on porcelain plates would require replacing or reducing materials and processes that significantly contribute to GWP, AP and EP at various stages in the life cycle of porcelain plates. In addition, the use of renewable energy will reduce the carbon footprint while water footprint of porcelain plates can be reduced by implementing water reuse and recycling.
