ESG Report 2021

Innovated the production processes to reduce water consumption, such as: Increased the awareness of water conservation among employees through strengthening the publicity of laws and regulations related to water-saving by means of meetings, videos and display boards 69 Recycle and reuse the condensate water of the whole plant, including steam pipeline condensate, machine seal cooling water, condensate water from material concentration, etc.; Recycling and reuse of bacteria residue filter fluid; and The low-temperature secondary dialysis solution is heated by the high-temperature product benzene acetic acid delivery solution to save steam. Incorporated consumption reduction indicators into the annual assessment of each production plant Strengthened the management of regular maintenance of water equipment to prevent leakage or dripping, so as to practice turning the faucet off at will Environmental, Social and Governance Report 2021 The United Laboratories International Holdings Limited Water Conservation Measures in Production Plants Water Conservation Measures in Offices Water Conservation Optimisation Projects of the Year The production plants carried out technical transformation to promote the reuse of steam condensate, and the monthly consumption of potassium salt was reduced from approximately 5,000 tonnes to 200 tonnes. It is estimated to save 57 , 600 tonnes of water each when running full capacity. Steam condensate recycling The production plants collect the secondary cleaning membrane water to the drinking water storage tank for the process section, which is used for the first cleaning operation of the nanofiltration membrane, saving 6,300 tonnes of water each year. Recycling of secondary membrane water Maintenance ponds eliminate leakage and pollution of groundwater, and avoid the risk of mixing up pressure on the discharge pipelines and freezing in winter Maintenance accident pool
