1. Waste Management.
All waste generated during the activities, products, and services in the factory has a certain impact on the environment. Therefore, during the activities, storage, removal, and treatment processes, it complies with environmental protection regulations and reaches the waste efficiency level. control management.
a. Storage: Before disposal, waste is stored in specific locations or storage container facilities to prevent leakage and environmental pollution.
b. Removal: All waste is entrusted to a removal and treatment agency approved by the government agency for proper final disposal.
c. Reduction: Reduce waste output by improving the process or changing the materials used (source reduction).
d. Recycling: It can be recycled through direct or indirect intermediate processing within the factory or outsourcing.
Waste output
The waste produced in the factory is divided into two categories: general industrial waste and hazardous industrial waste. The quantity leaving the factory is recorded by weighing . The total output of all types of waste in 2023 is 1106.4 metric tons, and the amount of waste from general enterprises is 328.7 metric tons, of which the weight of waste belonging to disposal and transfer is 266.9 metric tons, accounting for 81%, and the weight of direct disposal waste is 61.8 metric tons; hazardous enterprises The amount of waste was 777.7 metric tons, of which 776.2 metric tons, or 99%, were transferred for disposal , and 1.5 metric tons were directly disposed of. The overall reuse rate is 94%.

2. Wastewater Management.
For the wastewater generated during the production process, the factory has two sets of complete wastewater treatment system facilities. It uses wastewater separation, chemical coagulation, activated carbon adsorption tower and other equipment to reduce heavy metals and other substances in the wastewater to comply with current environmental protection regulations. Require emissions to reduce environmental pollution load.
The total wastewater discharge in 2023 will be approximately 146.5 million liters, an increase of approximately 12% from 2022.
Environmental monitoring：
a. Self-testing: Wastewater and discharged water should be analyzed and tested daily for water quality. The testing items are pH,COD, Cu, water temperature.
b. Outsourcing testing: In accordance with the provisions of environmental protection laws and regulations, a testing company licensed by the central environmental protection agency is commissioned to conduct water quality testing once every three months. The testing items include pH, COD, SS,Cu, BOD, water temperature.
c. Exhaust gas management.
The factory is equipped with seven washing tower equipment, six bag dust collector equipment, and one activated carbon adsorption tower equipment to effectively treat the waste gas emitted during the manufacturing process, ensure the normal operation of the control method, and improve the efficiency of air pollution prevention. , to reduce the environmental impact caused by exhaust emissions.
Environmental management plan
In order to comply with the spirit of ISO14001, we set goals to promote management plans and achieve environmental policies in terms of pollution prevention, compliance with regulations, and continuous improvement.
1. When replacing equipment, priority will be given to models with first-level energy efficiency certified by the state.
2. Prioritize the purchase of new energy vehicles when replacing official vehicles.
3. When replacing mechanical equipment, priority should be given to the frequency converter type. If the replacement period is not reached, a frequency converter should be installed.
4. Recycling of a full range of waste.
5. Increase the recovery rate of precious metals from wastewater.
Environmental certification.
