Environmental impact analysis of plant fibers and their composites relative to their synthetic counterparts based on life cycle assessment approach

This study analyzed the characteristics of the environmental impacts of apartment buildings, a typical housing type in South Korea, as part of a research project supporting the streamlined life cycle assessment (S-LCA) of buildings within the G-SEED (Green Standard for Energy and Environmental Design) framework. Three recently built apartment building complexes were chosen as study objects for the quantitative evaluation of the buildings in terms of their embodied environmental impacts (global warming potential, acidification potential, eutrophication potential, ozone layer depletion potential, photochemical oxidant creation potential, and abiotic depletion potential), using the LCA approach. Additionally, we analyzed the emission trends according to the cut-off criteria of the six environmental impact categories by performing an S-LCA with cut-off criteria 90–99% of the cumulative weight percentile. Consequently, we were able to present the cut-off criterion best suited for S-LCA and analyze the effect of the cut-off criteria on the environmental impact analysis results. A comprehensive environmental impact analysis of the characteristics of the six environmental impact categories revealed that the error rate was below 5% when the cut-off criterion of 97.5% of the cumulative weight percentile was applied, thus verifying its validity as the optimal cut-off criterion for S-LCA.

The Impact

Abstract Tofu is one of the processed soybean foods that are very popular with Indonesian society. Despite the popularity of Tofu, Tofu production in Indonesia is generally small and medium, reaching 500 kg per day, as in the tofu factory in Semanan, West Jakarta. The purpose of this study is to analyze the environmental impact of tofu production in West Jakarta. The life cycle assessment (LCA) approach was used to achieve this goal with SimaPro software for impact calculations. This research applies the LCA cradle to gate, which consists of soybean cultivation, transportation, and tofu production processes. The environmental impacts of tofu production analyzed in this study include global warming, ozone depletion, acidification, and eutrophication. The impact analysis showed that the acquisition of soybeans, which consisted of soybean cultivation and transportation, had the most significant environmental impact with a global warming potential value of 0.882 kg CO2 eq out of a total of 0.978 CO2 eq for the whole process.
