ESG Report 2021

75 Environmental, Social and Governance Report 2021 The United Laboratories International Holdings Limited The circulating fluidised bed boiler of Inner the emission concentration of sulfur dioxide is Mongolia Company has been put into not more than 35mg/Nm ³ , the emission operation since 2014. It adopts bag dust concentration of dust is not more than c o l l e c t o r s , l i me s t o n e - g y p s um we t 10mg/Nm ³ and the emission concentration of desulfurization, SNCR denitration and other nitrogen oxides is not more than 50mg/Nm ³ . technologies for exhaust gas treatment. The In order to comply with and cooperate with concentration of the main discharge outlet of the action plan, Inner Mongolia Company the chimney meets the requirements of the actively implemented the transformation of Emission Standard of Flue Gas Pollutants for ultra-low emission technology, transformed Thermal Power Plants. Since the release of the flue gas treatment facilities in the the “2020 Action Plan of Bayannur City to workshop, and reduced the emission Win the Blue Sky Defense War”, the concentration of flue gas pollutants to emission of the workshop of Inner Mongolia improve the air quality of the environment in Company has been required to meet the Bayannur. emission standards set out in the plan, and Background Inner Mongolia Company invested in the construction process, including the treatment design, installation, commissioning and of boiler flue gas emissions, the discharge of construction of ultra-low flue gas emission production wastewater to the Company's civil engineering. The project transformed the reclaimed water reuse system for recycling, boiler desulfurization system and induced and the use of silica acid aluminum sound insulation in the flue. fans in five 260 - tonne circulating fluidised bed boilers, and added 5 sets of external SCR denitrification equipment and supporting facilities. In addition, the Company also allocated funds for the procurement, installation and commissioning of online monitoring equipment. The total investment of the project was RMB64 million. Environmental protection measures are in place during the Project Status Objectives and Effectiveness After the renovation project is implemented, the emission from the production plants will be cleaned, the air quality of the area will be improved, and the national and local environmental objectives will be achieved. The transformation of boiler flue gas system is in line with the Company's operation, and its annual operating cost will not cause economic burden. The unit pollutant emission reduction cost is only RMB6.27 per kilogram. This project is a demonstration of Inner Mongolia Company Ltd. to build an environmental-friendly circular economy, and has contributed to the sustainable development of the local society and economy.
