Study of Environmental Impact Improvement for Fish Feed Production Companies

Abstract

The national fish consumption increases from 2020 to 2021 of 1.10%. The practices of fish feed production have direct environmental impacts related to emissions to air, water, and soil. The fish feed production process is divided into several stages including the intake, fine grinder, mixer, press, post pellet, dryer, cooler, sieveter, bagging off, and boiler. Considering the environmental impacts from fish feed production activities, there is a need for analysis of those impacts using the LCA method. LCA includes four stages: goal and scope definition, LCI, LCIA, and interpretation. This research is limited to the fish feed production process (gate to gate) and is based on the impact category method ReCiPe 2016 (H) with a midpoint characterization factor. Subsequently, determining environmental improvement program recommendations based on LCA study results and the AHP. The results of the LCA analysis on fish feed production indicate that the production of 1 ton of fish pellets generates 13 impact categories using the ReCiPe 2016 (H) midpoint method. The hotspot in the fish feed production process are found in the boiler unit with the global warming impact category (487,5868956 kg CO? eq/ Ton of fish pellets) and the WWTP with the freshwater eutrophication impact category (0,0003883 kg P eq/Ton of fish pellets). The global warming impact is influenced by the emission inventory of CO2, CH4, and N2O, while the freshwater eutrophication impact is influenced by the inventory data of COD and BOD5.
