"after the flue gas from the coal-fired boiler is discharged, it goes through purification, adsorption, analysis and other processes to capture and purify the carbon dioxide, which can then be used as a raw material for the production of acetic acid." niu wenping, administrative manager of hebei jiantao energy development co., ltd., enthusiastically introduced that the company has currently formed a stably operating carbon capture and carbon utilization production line.

walking into the carbon capture area of ​​hebei jiantao energy development co., ltd. in neiqiu county, xingtai city, hebei province, the reporter saw that near the towering coal-fired boilers, metal pipes crisscrossed and connected several huge blue towers. on the big screen next to it, real-time data on the entire process of carbon generation and carbon capture were displayed.

"in the past, companies needed to purchase 100,000 tons of carbon dioxide every year. now, through carbon dioxide capture and recycling, we not only save raw material costs, but also achieve considerable environmental benefits. it is estimated that the amount of carbon dioxide recycled by companies each year is equivalent to the total carbon absorption of nearly 10,000 acres of forest in one year." niu wenping said.

from "big carbon emitters" to "pioneers in carbon capture", in recent years, many companies in hebei have begun to explore and promote carbon capture, carbon utilization and carbon storage. wang yunjing from the climate change and foreign cooperation division of the hebei provincial department of ecology and environment told reporters that at present, hebei is promoting the development of the carbon industry through pilot demonstrations, building technical platforms, strengthening financial empowerment, and establishing a carbon reduction product methodology system. it has included relevant demonstration projects in the scope of provincial carbon emission reduction projects, carried out emission reduction verification and registration, and promoted the realization of the value of corporate carbon emission reduction assets.

as a traditional industrial province, hebei's carbon emissions are mainly concentrated in key industries such as electricity, steel, and building materials. among them, the steel industry has the largest emissions, accounting for more than half of the carbon emissions in the industrial sector.

in the laboratory of beijing university of science and technology, the reporter saw a sample of "negative carbon stone" produced by using carbon dioxide and steel slag. "this is a steel slag carbon fixation project jointly carried out by us and beijing university of science and technology. steel slag can be used to directly capture and utilize carbon dioxide in flue gas to produce antique building materials and other negative carbon materials. each ton of steel slag can fix about 180 kilograms of carbon dioxide." tian jinglei, director of the sustainable development research center of hesteel group, said that the group has currently built a thousand-ton industrial demonstration project of steel slag carbon fixation in tangshan new district.

"we are currently focusing on the research and development of low-cost, large-scale carbon capture, carbon utilization and carbon storage technologies around steel production scenarios." tian jinglei said that at the same time, the group is actively creating a carbon data management platform and strengthening the construction of a carbon emission reduction accounting system in the steel industry to prepare for entering the national unified carbon market.
