To date, the landfill is overcrowded due to an increase in the amount of waste coming in. The landfill has 450,000 tons; as of 1 January 2021, there are 710,714 tons of garbage. Landfill overflow contributes to the spontaneous combustion of waste. Waste fires occur during the rotting process and the release of biogas, which reacts with oxygen to ignite a fire.
