Abstract

SP-36 fertilizer is a single fertilizer that has a phosphorus content in the form of 36% of P2O5 and it’s made of phosphate rock. The principle of the process of making SP-36 fertilizer is reacting phosphate rock with sulfuric acid and phosphoric acid, which in this case is called mixed acid. With a high production capacity, it is possible that there are emissions/by-products of the production process that have an impact on the environment. In this study, an approach with the Life Cycle Assessment (LCA) method was applied to the SP-36 fertilizer production process. LCA is a method that can analyze the impact of a product’s life cycle on the environment. The aim of this study is to identify the amount of environmental impacts from the SP-36 fertilizer production. This research using software Sima Pro 9.0.0 to help calculate the magnitude of the impact. The scope of research is gate to gate or during the SP-36 fertilizer production process, this research conducted in midpoint with the TRACI method which will review the impact categories of ozone depletion, global warming, smog, acidification, eutrophication, human health (carcinogenic, non-carcinogenic, and respiratory effect), ecotoxicity, and fossil fuel depletion.Based on the analysis results, the biggest impact during the SP-36 fertilizer production process comes from the reaction unit. It’s because the use of phosphoric acid chemicals as raw material for SP-36 fertilizer. The impact category that had the highest value during the SP-36 fertilizer production process was carcinogenic.
