Modeling the impact of the COVID-19 pandemic on air emissions indicators of climate change originating from solid waste management in coastal settlements

Abstract

COVID-19 was first reported in Indonesia on March 2, 2020. Several actions have been taken, such as limiting population mobility and prohibiting almost all activities that can be avoided. This policy has environmental consequences, especially the amount of solid waste generation. This study provides a view of the effect of COVID-19 on the amount of solid waste generation and composition in coastal settlements, the impact on air quality which has implications for climate change, and provides the most efficient solid waste management solution. Measurement of solid waste data using SNI 19-3964-1994 and air emissions analysis using the IWM2 software. On the basis of this quantitative analysis, we reached the following conclusions: (1)the reduction of solid waste generation is 15,47% with the composition during the pandemic namely organic 41,4%; wood 3,4%; fabric/textile 1,1%; rubber/leather 13,4%; plastic 21,3%, iron 5,5%; Glass 3,9%, paper 0,2% and residue 6,8%, (2) the resulting air emissions decreased by parameters CO2 of 32.33 tons/year (37.97%), CH4 of 14.37 tons/year (38.14%), and Global Warming Potential (GWP) of 334.01 tons/year (38.12%), (3) the most efficient management of solid waste for coastal settlements during the COVID-19 pandemic period is the process of recycling, biological processing, and bringing residues to landfill.
