In addition, SL Corporation collects all landfill gas (LFG) generated by the natural decomposition of landfill waste and uses it as fuel for a 50 MW power generation facility. Last year, the company produced and sold a total of 188.7 GWh of electricity, which is equivalent to the annual electricity consumption of approximately 50,000 households and the power consumption of three data centers.

The total amount of waste brought into the Sudokwon Landfill Site last year was 1,072,000 tons, a decrease of about 17% compared to the previous year (1,293,000 tons). The amount of waste received decreased by 39% in 2022 and by 27% in 2023, with the downward trend continuing last year.

The total area of the Sudokwon Landfill Site is 16 million square meters. The first and second landfill sites are currently under post-closure management after the completion of waste landfilling. As of the end of May, the landfill utilization rate of the currently operating Section 3-1 was 64%.

Song Byeongeok, President of SL Corporation, stated, "The Sudokwon Landfill Site is establishing itself as an environmental platform that goes beyond a simple waste treatment facility, encompassing resource circulation, renewable energy production, and greenhouse gas reduction."
