| Summary: | Food waste has become a global issue and a serious concern for various institutions ranging from food security agencies to environmental organizations. This study aims to identify municipal food waste, both in terms of waste generation, composition, physical and chemical characteristics through sampling, carried out through 2-stage composition referring to SNI 19-3964-1994 related to the method of taking and measuring samples of waste generation and composition of municipal solid waste, also to determine the potential impact of this type of waste in the city of Bandung, especially those that are correlated with climate change. Later, based on knowledge of the characteristics of a food waste household, this study will also provide recommendations for specific waste management based on its characteristics by considering the impact of climate change from each treatment. The results of this study founds that the waste generation of food waste in Bandung reached 0.264 kg/person/day. General waste composition are dominated by food waste and the largest composition of food waste is composed of fruits and vegetables (65%). Bandung city’s food waste has an edibility rate of 18.92%. This causes food waste to have a high water content (74.78%) which is correlated with its high volatility (90.42%). With high volatility, food waste has a high C/N ratio (24.52:1) and releases greenhouse gases that indirectly trigger climate change. Based on the existing food waste management condition, the total CO2eq emitted is 16,488,3041 Gg/year with 31.46% managed and 68.54% unmanaged emissions. Alternative food waste management to be implemented until 2030 is the “Alternative 3 – Optimistic Scenario” suggested by the author. This scenario can be predicted to reduce the environmental impact in the form of food waste generation to only 179.015 ton/year (67.86%) and unmanaged CO2eq emissions to 9,221.25 Gg/year (50.76%) both of which are in line with the Indonesia’s NDC target. The economic impact of the alternative is ‘only’ Rp 53.56 B/day, smaller than other alternatives which exceeds Rp 70 B.. |
