In order to enhance the standardized management level of hazardous waste in the company, effectively prevent and control environmental risks, and reduce the 
impact of hazardous waste on the environment, the company has taken multiple measures to continuously improve the standardized management level of 
hazardous waste, effectively prevent environmental risks, maintain ecological environmental safety, and ensure the health and safety of all employees:

1. Build a compliant hazardous waste warehouse that meets the "four preventions" and other construction requirements, ensuring the storage needs of hazardous 
waste are met.
2. Some hazardous wastes are regularly disposed of by qualified third parties, ensuring clear inventory, compliant disposal, definite whereabouts, and standardized 
management.
3. In the synthesis workshop, two sets of condensers are used to condense and recover the exhaust gas from equipment venting.
4. Install activated carbon adsorption devices, ensure standardized operation, and perform adsorption treatment on volatile organic compounds generated by 
equipment venting in the synthesis workshop and distillation workshop.
5. To ensure that exhaust emissions meet the standards, an exhaust gas condenser has been installed on the company's main exhaust pipe, and the company 
entrusts external qualified institutions to conduct annual testing on exhaust emissions.
6. The equipment department conducts regular equipment maintenance to ensure the normal operation of environmental protection equipment, thereby ensuring 
that pollutant emissions meet the standards.
