South Korea: All nine domestic cement producers and the Ministry of Environment have agreed on measures to reduce NOx emissions. Asia Cement, Halla Cement, Hanil Cement Manufacturing, Hyundai Cement, Korea Cement, Sampyo Cement, Ssangyong Cement Industrial, SungShin Cement and Union Corporation have agreed to invest in upgrades to filters or new high-efficiency filters and process improvements, according to the Korea Times newspaper. There was also an agreement to set NOx emissions reduction targets for the allocation of funding. The Korea Environmental Industry Technology Institute is investing US$2.93m in research towards developing methods of selective catalytic NOx emissions reduction and selective non-catalytic NOx emissions reduction.
The government aims to reduce national NOx emissions by 20% to 155,000t/yr from 195,000t/yr through subsidies to emissions reduction technologies development and uptake. The cement sector presently emits 62,500t, 32% of the domestic total.
