Waste Management

We hope to achieve the vision of zero waste through source classification, process waste reduction, recycling and reuse, and incineration and landfill. Industrial waste cleared in 2023 totaled 1,517,891.53 tons, in which general industrial waste accounted for 1,517,451.16 tons and hazardous waste accounted for 440.37 tons. There were no severe leakages of waste in 2023.

Of the general industrial waste, 96% (1,465,345.88 tons) was reused, including reusing sandblasting waste in cement products and reusing waste wood as fuel, 2% (28,682.18 tons) was incinerated, 1% (12,529.89 tons) was landfilled, and 1% (10,893.21 tons) was treated using other methods (e.g., physical treatment and thermal treatment). Of the hazardous industrial waste, 49% (217.30 tons) was incinerated, 1% (3.30 tons) was treated overseas, and 50% (219.77 tons) was treated using other methods (e.g., solidification and chemical treatment).

The volume of waste cleared per unit of product was 50.19 kg/ton in 2023, an increase of 7.11 kg/ton compared with last year. Due to the different periodic maintenance items this year, general industrial waste increased by approximately 139,800 tons, and the volume of waste cleared per unit of product also increased. The volume of waste incinerated and buried per unit of product was 1.37 kg/ton, up 0.04 kg/ton compared with last year. Efforts are still directed in recycling for waste reduction, in order to reduce the volume of waste incinerated and buried.
