Throughout 2021, our Gedian-based branch company bought externally-sourced steam instead of direct use of petrochemical energy, successfully bringing SO2 and NOx emissions down to 0. In Jiangxia, continual use of renovated low NOx boilers helps reduce NOx emissions and maintain SO2 emissions at 0 continually. The replacement of coal with natural gas improves thermal efficiency and thereby reduces total carbon emissions. There’s waste gas monitoring all year round and fermentation tail gas and after-treatment tail gas are gathered, treated and reduced using the water wash system and photolysis system. In 2021, we spent ¥1.355M in energy conservation and emissions reduction as well as ¥5.6413M in environmental protection.
