Waste Management

Most of the Company's waste is not generated during the manufacturing process, but rather during fuel combustion and regular inspections. We achieve our vision of zero waste through four major directions: source classification, process waste reduction, recycling and reuse, and incineration and landfill.

Waste is declared in accordance with the law, and qualified vendors are selected for disposal. The Company also conducts annual factory visits for statutory items such as industrial waste. Plant industrial waste cleared in 2024 totaled 1,328,920 tons, in which general industrial waste accounted for 1,328,435 tons and hazardous waste accounted for 485 tons; all of which were processed off-site. There were no severe leakages of waste in 2024.

Overview of Waste Management

Of the general industrial waste, 96.40% (1,280,597 tons) was reused, including reusing sandblasting waste in cement products and reusing waste wood as fuel, 1.84% (24,410 tons) was incinerated, 0.77% (10,231 tons) was landfilled, and 0.99% (13,197 tons) was treated using other methods (e.g., physical treatment and thermal treatment). Of the hazardous industrial waste, 58.35% (283 tons) was incinerated, 0% (0 tons) was treated overseas, 41.65% (202 tons) was treated using other methods (e.g., solidification and chemical treatment), 0% (0 tons) was landfilled, and the proportion recycled was 0%.

The volume of waste cleared per unit product in 2024 was 46.92 kg/ton, a decrease of 3.27 kg/ton compared to last year. The volume of waste incinerated and landfilled per unit product was 1.23 kg/ton, down 0.14 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.

Note 2: The amount of waste cleared is calculated by adding the total amount of general waste and hazardous waste removed (calculated based on the amount of waste removed recorded in the waste triplicate form).
Note 3: All of the aforementioned waste was treated off site.
