CSRC complies with various waste disposal laws and regulations to ensure that all waste generated is properly disposed of. In order to live up to the spirit of responsible production and circular economy, each plant has kept abreast of the source, type, and quantity of various waste resources, and ensured that their disposal methods and flows are in compliance with all environmental laws and regulations, to further achieve the goals of cleaner production, resource recycling and industrial waste reduction to achieve the goals of pollution reduction, waste reduction, and environmental protection. In 2023, the Group achieved a waste recycling rate of 80.4%, of which 87.9% in Greater China, 72.0% in India, and 51.4% in the United States. All are expected to achieve short-term targets ahead of schedule.

In 2023, the Group's total waste generated was 6,767.5 tons (Note), a significant decrease of 13% from 7,742.8 tons in 2022. In Greater China, Anshan uses incineration method to dispose of general solid waste, which has led to significant reduction of waste.

Note Total waste generated = non-hazardous waste + hazardous waste

CSRC's waste management process

All plants in Greater China comply with local waste management regulations. In 2023, the total waste generated by Linyuan Advanced was 1,423.4 tons, of which the total waste recycling rate reached 100%. In order to reduce the waste discharged and increase the waste reuse rate, Linyuan Advanced have implemented waste classification to effectively collect and plan for recyclable resources, while reducing the cost of general waste disposal and the amount of waste incinerated. In addition, there is also an area in the plant, in which pallets recycled from customers are divided into three categories for reuse: (1) pallets with good appearance and body are sold to suppliers in need; (2) remaining pallets are selected for reuse in the plant; (3) pallets that are damaged and cannot be reused will be sent to the waste treatment process.

The waste generated by Maanshan, Anshan, and Chongqing is disposed of in accordance with the laws and regulations of China. All waste is collected and disposed of off-site, and garbage classification is carried out to sort out business waste, recyclable waste, and hazardous waste. Hazardous waste is temporarily stored in the hazardous waste temporary storage area, and legal third-party disposal companies are appointed to clear and transport the waste to hazardous waste disposal sites for legal disposal. The waste recycling rate of Maanshan was 99.3% in 2023. The waste is mainly desulfurized gypsum and sludge from sewage treatment, which are recycled and remade into cement and brick kilns. The rest of the general business waste is recycled for incineration for power plants. The waste recycling rate of Anshan in 2023 was 100%, a significant increase from 70% in 2022, mainly due to the switch to incineration treatment and the implementation of multiple recycling and reuse policies, including the recycling of desulfurized gypsum to make cement, as well as the recycling, reprocessing, and reuse of some scrap iron, scrap steel, PP bags, and pallets. The hazardous waste of Chongqing is incinerated according to the regulations, while the non-hazardous waste is still buried in landfills. The waste generated by the plant is temporarily stored in the hazardous waste temporary storage area, and legal third-party disposal companies are appointed to clear and transport the waste to hazardous waste disposal sites for legal disposal.

CCET in India has formulated relevant standard operating procedures for waste collection, removal, and disposal. Waste insulation materials, waste petroleum sorbent pads, chemical sludge, and evaporators should be placed in the specified containers, and hazardous waste should be stored in specified hazardous sites and disposed of at the TSDF facilities and incineration plants registered according to the GPCB. In order to manage waste, CCET has obtained membership from a third party authorized by the government. The total waste generated by CCET in India in 2023 was 96.9 metric tons, 57 tons of which was non-hazardous waste gypsum. The waste recycling rate in 2023 was 58.8%. CCIPL is equipped with a confined space for the storage of hazardous waste, and its disposal is outsourced to qualified hazardous waste treatment companies.

The waste removal and disposal are strictly controlled to reduce the impact on the environment. The plant implements a waste classification and packaging system and packages waste according to types and regulatory requirements to prevent leakage from causing environmental pollution. To avoid hazards to humans, personnel are required to use appropriate personal protective equipment (PPE) and follow regulations during waste handling, loading, and transport to disposal facilities. CCIPL constantly reviews and updates its waste management policy, hoping to effectively reduce waste and increase waste recycling. In 2023, the total amount of waste was 190.2 tons.

All waste generated by CCC Sunray in the United States is in compliance with laws and regulations, and qualified third parties are appointed for disposal. All waste is landfilled, and the plant does not generate hazardous waste. The same types of materials are recycled and reused in the plant to actively reduce waste output. The waste generated in 2023 was 96 tons. The waste generated by CCC Ponca in the United States is landfilled, incinerated, and recycled in accordance with the laws and regulations of the United States. The total waste in 2023 was 1,793.4 tons, and the waste recycling rate was 54.2%, mainly for hydrated lime for roadbed stabilization and agricultural use.

Waste amount of CSRC over the past three years

Note 1	Linyuan Advanced in Greater China disposes of non-hazardous waste and stabilizes other types of waste; Anshan disposes of non-hazardous waste and recycles and sells other types of waste.
Note 2	The first production line of CCET in India commenced operations at the end of 2022, so there is no data for 2021 and 2022.
Note 3	Waste recycling rate = [volume of recycled waste (including heat treatment, physical treatment, recycling, and sales of the recycled) + volume of waste incinerated with energy recovery] ÷ total waste generated.
