Life cycle assessment of powder milk production in Indonesia

Abstract

The industry is a human activity established to process resources or materials into goods or products that humans can utilize. The dairy processing industry is one of the industries that process raw milk into various products, such as milk powder. The process of dairy processing industry activities not only produces a product but also contributes to environmental impacts. The main objective of this research determines the most potential environmental impact caused by the production process. The research will be conducted on milk powder products manufactured by PT X. The products chosen in this research are a product with a size of 40 grams per-sachet (product A) and product with a size of 200 grams per-sachet (Product B). The LCA research boundary is “gate to gate,” such as materials transportation from supplier, manufacturing process and management waste. The method used to determine the potential environmental impacts is life cycle assessment (LCA) method. Software SimaPro v.9.1 calculates the impact assessment. The calculations showed potential environmental impacts on product A and product B, such as Marine Ecotoxicity, Freshwater Ecotoxicity, and Human Toxicity. Based on the process stages of product A and product B, the potential environmental impact arises from the manufacturing process.
