1. Wastewater Management

The wastewater produced includes domestic sewage, industrial wastewater from laboratories, etc. We ensure the compliance of sewage discharge and clarify the waste water management process in accordance with the Management Measures of Environmental Protection. We discharge it into the municipal pipeline network after relevant treatment in accordance with the requirements of the local government and conduct regular monitoring to prevent excessive discharge. In 2021, we strengthened the management of wastewater discharge. We installed flow meters and detection devices in industrial wastewater discharge outlets and strengthened the management of the emission concentration, rate, total amount and operating time of treatment facilities for each emission factor. Data of wastewater discharge is expected to be disclosed from 2022.

2. Exhaust Gas Management

We manage exhaust emissions from the overall level in accordance with the Management Measures of Environmental Protection requiring each subsidiary/branch to select processes and equipment that do not generate or low generation of exhaust gas. We shall test the exhaust gas and strictly control the emission of pollutants. We shall not violate the emission permit and exceed certified emission limits. We equip the laboratory with corresponding ventilation facilities in accordance with regulations. The R&D and production operations involving volatile organic compounds are all carried out in a fume hood or exhaust hood with local ventilation. At the same time, we cover various containers for storing chemicals in time to minimize the volatilization of volatile organic compounds. We properly handle the exhaust gas generated during the experiment and discharge it after the treatment reaching the standard. It is strictly forbidden to directly discharge the exhaust gas that does not meet the standard to the environment. For construction projects, we are equipped with reasonable processing technology and technical personnel as to comply with local government requirements to do a good job of monitoring.

Note: The data covers 23 sub/branches with industrial emissions.

3. Waste Management

Hazardous and non-hazardous waste generated by our business operations mainly includes chemicals, test samples, organic waste, waste liquid, paper, plastic, office waste, electronic waste, etc. We generate less waste than traditional industries. The amount of different wastes produced varies according to the business that each laboratory focused. However, we still pay close attention to the generation and treatment process of these wastes and strictly require the laboratory to carry out special personnel management and special warehouse storage of the samples after testing. We regularly hand them over to professional institutions for processing.

In 2021, we established a waste management data statistics mechanism. We managed the general solid waste generated throughout the process. In the management process of collection, identification, weighing, storage, and disposal, pollution must be strictly avoided. For example, when storing and processing waste materials, the materials should be put into the designated waste material transfer channel. When they are stored outside the laboratory, they should be placed in designated temporary storage locations. The cleaning management and protection should be done well.

Hazardous chemical waste management

Due to the particularity of our business, we need to use hazardous chemicals for testing. Therefore, in accordance with national regulations and policies such as the Regulations on the Safety Management of Hazardous Chemicals, we have formulated a number of systems such as the Measures for the Safety Management of Hazardous Chemicals to standardize the use and disposal of such chemicals. In accordance with relevant laws and regulations, we organize HSE training for legal persons, general managers, chemical procurement personnel, and chemical users to ensure that relevant personnel have sufficient capabilities to use and handle chemicals in an appropriate, safe and standardized manner.

Medical Waste Management

Medical waste is also the waste that we focus to control. In accordance with the Management Regulations of Medical Waste, they are uniformly processed by a specialized medical waste treatment company and strictly record the treatment process to ensure that all wastes are disposed of in the correct way.
