Study on the impact of crab processing waste using LCA in Karawang Regency

Abstract

Crab is a leading commodity in the white sand area of Karawang Regency. As a crab processing center, this area produces crab wastes, including shells and by-products. This study aims to identify inputs and outputs resulting from crab processing, calculate the size of the life cycle of the crab processing industry, and reduce environmental damage. In a Life Cycle Assessment (LCA) research, this study uses the environmental impact assessment method with stages of inventory analysis, impact assessment, and interpretation and improvement. This study shows the magnitude of the environmental impact of GHG emissions and the energy efficiency of crab processing through calculated, analyzed, and proposed improvement scenarios. The impact analysis results show that 1 kg of crab products contribute to GHG emissions of 0.56 g CO2eq, with refrigerant for the refrigerator of 1.62 g CO2eq. Changing the refrigerant and making efficient water usage can reduce the impact. This research is expected to increase the use of resources and encourage further research to use LCA for waste reduction and crab waste treatment.
