ESG Report 2025

The United Laboratories integrates clean production and green operation principles into daily management and continues to reduce the environmental impact of production and operations through multi-dimensional measures such as process optimisation, resource circulation and employee training. 7.4 Green Operation 7.4.1 Green factory Inner Mongolia Company has been recognised as a national-level “Green Factory”. It vigorously promotes cleaner production, improves production processes, formulates emergency response plans for environmental incidents, and provides environmental protection training, actively fostering environmental protection and gradually infusing the concept of green production into the corporate culture. Inner Mongolia Company has established a green factory construction implementation plan, investing substantial resources in areas such as “intensive land use, harmless raw materials, clean production, waste resource recovery, and low-carbon energy”. It systematically develops corresponding work measures and targets, normalising the operation mode of the green factory and green development management, aiming to achieve industry-advanced levels across various green factory goals. To effectively manage and maintain the characteristics of the green factory, the Company implements assessment and reward measures for employees, carrying out green environmental protection work in an orderly and efficient manner. The Group ensures capital investment in Inner Mongolia Company, strengthens technological innovation, and ensures that production technology, equipment, energy and resource inputs, products, environmental emissions, and performance all meet national green factory standards. We have always attached great importance to energy metering management, advocating energy conservation, emission reduction, and dual control of energy consumption. From standardising the data collection network to internal audits of energy metering and flow, Inner Mongolia Company adopts a rigorous approach and has established a comprehensive energy management system. During the Reporting Period, the energy metering evaluation team jointly formed by the Inner Mongolia Autonomous Region Institute of Metrology and Testing and the BayanNur Municipal Administration for Market Regulation conducted an on-site review of Inner Mongolia Company's energy metering and gave high praise to the Company's energy metering management. To cultivate energy-saving habits among all employees, the Group regularly organises electricity saving campaigns. Leaders of each subsidiary take the lead in promoting electricity conservation, setting an example and raising all employees' awareness of saving and using electricity scientifically. When lighting is sufficient, lighting power is turned off or the number of light sources is reduced, and lights are turned off when leaving a room to eliminate unnecessary lighting. Air conditioners are set at 26°C or above, and their usage time is reduced. When offices are unoccupied, office equipment and household appliances are promptly turned off to reduce standby power consumption; elevator use is minimised. The Group also avoids using high-power electrical equipment during peak electricity hours. The Group rationally controls street lighting and excess lighting, promotes the use of energy-saving products, and phases out high-energy-consumption equipment. The Group supports and cooperates with various workshops and departments in the scientific management of electricity use. For office equipment such as copiers and printers, power is turned off when not in use for extended periods. Staff turn off lights, air conditioners, office equipment, and instrument equipment when leaving the office. During the day, corridor lights and bathroom lights on each floor are turned off in a timely manner. Energy-efficient lamps and appliances are used as much as possible, and all electrical equipment is adjusted to the optimal energy-saving state. To better manage the Group's pollutant discharge process, strive to reduce pollutant emissions, and avoid adverse environmental impacts, Inner Mongolia Company continues to implement various cleaner production management requirements and continuously improves its cleaner production strategy, which focuses on the following four key areas: 7.3.3 Waste management The United Laboratories strictly supervises and controls waste generated during the production process, and formulates corresponding management measures and emergency plans for different categories of waste. Waste generated by the Group is classified into two categories, namely non-hazardous waste and hazardous waste. Handled by qualified parties for recycling and reuse (for example, waste diatomaceous earth and sludge are used in the production of organic fertiliser, and waste glass is recycled for remanufacture) Hazardous waste Mycelium residue, waste activated carbon, waste enzymes, concentrated phenylacetic acid liquor, waste mineral oil, MVR concentrate, etc. Reused in production where reusable (such as concentrated phenylacetic acid); where reuse is not possible, harmless treatment is carried out through the Group's integrated boiler disposal system or by qualified external parties Waste category Main source Treatment method Non-hazardous waste Waste diatomaceous earth, sludge, glass and domestic waste, etc. We adhere to the goal of ensuring that all waste is safely and harmlessly treated or utilised, and during the Reporting Period all waste generated was safely and harmlessly treated or utilised. To reduce sludge generation, in 2022 we invested RMB4 million to upgrade the original sludge horizontal screw centrifuge dewatering technology to a concentration plus high-pressure diaphragm filter press dewatering technology, and constructed a high-pressure plate-and-frame sludge dewatering project with a designed treatment capacity of 2,000 tonnes per day (sludge-water mixture), thereby effectively reducing sludge generation and external disposal costs. During the Year, the hazardous waste intensity (generation per tonne of product) of the Inner Mongolia Company was 5.58 tonnes, outperforming the target value of 8.50 tonnes. 49 The United Laboratories International Holdings Limited 2025 Environmental, Social and Governance Report
