Inner Mongolia Company generates air pollutants in being emitted. In order to ensure that the amount the production process, including exhaust gas with of emission does not exceed the legal standard, a peculiar smell generated from sewage treatment Inner Mongolia Company has formulated systems process, exhaust gas generated from production relating to pollutant monitoring. In addition to process, phenylacetic acid exhaust gas generated maintaining the automatic monitoring systems for from the fermentation process of phenylacetic acid relevant exhaust gases, the company has also recycling, smoke of coal-fired boiler and the commissioned a third party monitoring institution exhaust gas emitted by the used motor vehicles. In to regularly monitor the gas from pollution sources regard to the various types of exhaust gas, Inner in every month or quarter, so as to ensure that the Mongolia Company has set corresponding emission of exhaust gas complies with the Pollution treatment facilities and systems to undergo Control Standard for Hazardous Wastes recycling or purification treatment, and has Incineration (GB18484-2001). During the Year, all implemented organic exhaust gas treatment gas emission of Inner Mongolia Company did not projects, so as to ensure that all exhaust gas have exceed the standard limit. reached the national emission standard before Exhaust Gas Treatment For the exhaust gas with peculiar smell generated in the sewage treatment process, the factories adopt a measure to collect the odour source in a sealed way. The collected exhaust gas is deodorised through the process of “ multi-level alkali spraying+ozonation ” to reduce the impacts on the surrounding environment. Exhaust Gas Treatment Facilities and Systems In regard to the technical processes of different factories and the exhaust gas released, Inner Mongolia Company handle them by adopting treatment measures such as active carbon regeneration adsorbing, active carbon fibre absorbing, low- temperature plasma, alkali spraying and catalytic oxidation, so as to greatly reduce the emission of pollutants. In order to control the phenylacetic acid generated from fermentation plants and the peculiar odour emitted from the phenylacetic acid recycling process, Inner Mongolia Company adopts treatment processes such as the “ cooling + alkali spraying + carbon fibre absorbing ” to effectively prevent peculiar odour from spreading. 65 Environmental, Social and Governance Report 2020 The United Laboratories International Holdings Limited
