As the global steel industry advances low-carbon development, the maximum utilization of steel scrap will be the most practical approach to help reduce carbon emissions in the near- to medium-term future, suggests Zhong Shaoliang, chief representative of the Beijing office of the World Steel Association (WSA).
At present, the global steel industry still emits massive carbon-containing pollutants, with the total emissions reaching around 3.4 billion tonnes in 2020, according to WSA data Zhong shared with delegates at the China International Metal Recycling Conference 2022 in Kunming in Southwest China’s Yunnan province on July 28.
From China’s iron and steel industry development and policy perspective,based on the coupling method of the whole process of analysis and scenario analysis,China’s steel industry low-carbon development model the related policies were analyzed,combined with China’s current carbon reduction technologies mature;moreover,the future of China’s steel industry CO2 emission reductions and the optimal route optimization techniques were discussed.Results show that up to 2020 on the condition that optimal techniques routes or scenarios would come true,coking,sintering,iron making,converter,electric furnace and steel rolling process can reduce the amount of CO2 emissions for 77.33,4.4,7.13,54.36,116.2and 42kg/t,compared with 2010respectively;if integrated considering various end-processing-technology implementation,to 2020 carbon dioxide emissions would be 1.49 t only.These also indicate that currently in order to reduce CO2 emissions of steel industry in China,the key task is to adjust and construct policy to promote energy-saving and carbon-reducing technology implement.
