8.2.3 Waste Disposal The Group has strict monitoring and control on Company considers recyclable wastes as the wastes generated during the production resources, and collects and delivers them to the process. Apart from complying with the national qualified units for reuse, so as to effectively laws and regulations, Inner Mongolia Company minimize the amount of wastes disposed. For also formulates management measures and example, waste diatomite and sludge could be emergency plans for handling different types of used to produce organic fertilizer and waste glass wastes. The wastes generated by Inner Mongolia could be used for recycling. Company could be classified into two types, In order to reduce the costs of sludge generation namely non-hazardous wastes and hazardous and outsourcing utilization, the company wastes. invested RMB4 million to upgrade the original The non-hazardous wastes include waste sludge horizontal screw centrifugal dewatering diatomite, sludge and glass generated during technology to the "concentration + high-pressure production, as well as the general garbage diaphragm filter press dewatering" technology. generated in daily operation. Inner Mongolia Project Design generation. The project is to build a two-storey steel structure factory with a single storey building 2 area of 912m . The project will add major equipments including two sludge concentrators 3 with a processing capacity of 110m /h, two 3 sludge tanks with a volume of 75m , two PAC 3 dosing tanks with a volume of 25m , and four high-pressure plate and frame filters with a 2 filtering area of 450m . The design processing capacity is 2,000 tons per day (for sludge and water mixture), aiming to reduce sludge High-pressure Plate and Frame Sludge Dewatering Project. Waste Disposal Strategy Achieving waste reduction at the source, reducing waste generation Increasing the rate of waste disposal and recycling rate Waste Disposal Targets Key Results of Waste Disposal for This Year Reduce waste generation by by 2030 based on 2020 levels 30% Hazardous waste decreased by compared to last year Non-hazardous waste decreased by compared to last year. 21% 29% 76 Environmental, Social and Governance Report 2022 The United Laboratories International Holdings Limited
