| dc.description.abstract | PT XYZ is a company that produces NPK fertilizer as its main product. NPK
fertilizer has the potential to emit gases that are harmful to the environment. The
process that has a high potential for producing greenhouse gas emissions is
combustion because it produces gas emissions such as H2S, NOx, SOx, and NH3.
Based on interviews conducted, the company has not carried out an environmental
impact assessment specifically on gas emissions from the production process. The
objective of this study is to determine the environmental impact of the NPK fertilizer
production process and provide recommendations for improvements to reduce the
environmental impact caused by the company. Based on the existing problems, an
environmental impact assessment was conducted on 2 tons of NPK fertilizer using
the Life Cycle Assessment (LCA) method with SimaPro software, employing the
ReCipe 2016 database with 8 impact indicators. The results showed that the drying
process had the most significant environmental impact, affecting four indicators
that exceeded the established standard thresholds: stratospheric ozone depletion,
fine particulate matter formation, terrestrial acidification, and human noncarcinogenic
toxicity. Meanwhile, other processes such as Mixing, Granulation,
and Packaging only impacted two indicators, deemed unsafe: stratospheric ozone
depletion and human non-carcinogenic toxicity. The interpretation results suggest
several improvements: installing baghouse filters to capture dust particles before
gases are released into the atmosphere, using selective catalytic reduction
technology to reduce NO2 emissions, substituting wood fuel with natural gas to
lower emissions, using feeders to mix raw materials, and replacing the pan
granulator with a high-shear granulator. | en_US |
