ESG Report 2018

For the exhaust gas with peculiar smell generated in sewage treatment process , the factories adopt a measure to collect the odor source in a sealed way. The collected exhaust gas is deodorized through the process of “multi-level alkali spraying + ozonation” to reduce the impacts on the surrounding environment . 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 carbon fiber 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 workshops and the peculiar odor emitted from phenylacetic acid recycling process , Inner Mongolia Company adopts treatment processes such as the “cooling + alkali spraying + carbon fiber absorbing” to effectively prevent peculiar odor from spreading. EXHAUST GAS TREATMENT FACILITIES AND SYSTEMS 10 Environmental, Social and Governance Report 2018 The United Laboratories International Holdings Limited EXHAUST GAS TREATMENT The air pollutants generated by Inner Mongolia Company are mainly the exhaust gas with peculiar smell generated from sewage treatment process , the exhaust gas generated from production process , the phenylacetic acid exhaust gas generated from fermentation process of phenylacetic acid recycling , smoke of coal - fired boiler and the exhaust gas emitted by the used motor vehicles . In regard to the various types of exhaust gas , Inner Mongolia Company has set corresponding treatment facilities and system to undergo recycling or purification treatment , so as to ensure that all exhausted gas have reached the emission standard required by laws before emission . In order to ensure that the amount of emission does not exceed the legal standard, Inner Mongolia Company has formulated systems related to pollutant monitoring, and has also commissioned a third party to regularly monitor the gas from pollution sources in every quarter . During the Year , all gas emission of Inner Mongolia Company was found to be within the standard limit . Types of Air Pollutants Unit Nitrogen oxides ( NO ) x Sulfur oxides ( SO ) X Particulate matter ( PM ) Tons Tons Tons 1 Standard 477 337 80 820 805 246 1 . The standard follows the amount of air emission stated on the pollutant discharge license. 2 2017 2018 524 356 80 2 . Inner Mongolia Company started to use data extracted from the automatic monitoring system of exhaust gas as disclosure during the Year to more accurately present the situation of air pollutant emissions. Data of 2017 have been restated accordingly.
