| Summary: | Food waste can be considered as a global sustainability challenge due to its extensive environmental consequences and the fact that humans are unable to avoid food waste generation. This study aims to review food waste disposal technological approach available in Asian countries and also its environmental impact towards the technology treatment. A significant amount of food waste can contribute to global warming while the use of disposal technologies may cause significant environmental issues, inspiring researchers to conduct various studies. Regrettably, previous findings about the effectiveness of food waste disposal were not stated clearly. As a result, this study explained how the use of food waste disposal technology treatment affects the environment. A systematic search strategy based on the guidelines of the Priority Report on Systematic Review and Meta-Analysis Review Protocol (PRISMA) was developed and implemented using three databases: ScienceDirect, Scopus, and Web of Science. 17 publications were yielded from the search attempt and will be studied in depth. The results summarized five common food waste disposal technology approach which is landfilling, aerobic digestion (composting), anaerobic digestion, incineration and animal feeding. These technologies have adverse effects towards the environment global warming potential, climate change damage and also towards soil, water and air pollution. Hence, more research is needed to investigate these issues. © Penerbit UMT
