HAZARDOUS AND TOXIC WASTE MANAGEMENT SCENARIO FROM THE DOMESTIC AND OFFICE SECTORS IN SEMARANG CITY

The hazardous and toxic waste material from domestic and office sectors in Semarang is directly disposed of in the Jatibarang landfill without further processing. Appropriate management is needed as has been implemented in the medical sector. Therefore, this study aims to simulate the appropriate hazardous and toxic waste management in Semarang City from the domestic and office sectors. This research was conducted by analysing the existing conditions of hazardous and toxic waste management, followed by establishing a scenario of waste treatment through the projection of hazardous and toxic waste produced. The total waste generation of Semarang in 2031 is predicted to be 283.08 m3/day. It is predicted that Semarang City will require 22 incinerators to treat all of the waste. The ash residue would then be dumped in a hazardous waste landfill covering 0.89 hectares. Hazardous and toxic waste management, specifically from the domestic and office sectors, is expected to prevent adverse impacts on human health and the environment.
