In November 2021, the Carbon emission ranking of China’s listed companies (2021) was released.The 100 companies on the list emit 4.424 billion tons of carbon dioxide, more than 40 percent of national emissions;The top 10 companies account for nearly 20% of the country’s emissions;The top 20 companies account for about a quarter of the country’s emissions.Among the top 20 enterprises, there are 6 cement enterprises. It is not difficult to see that the road of “double carbon” of cement enterprises is doubly difficult.Source: Caijing & AMP;Limited by raw materials and production processes, the cement industry is quite difficult to reduce carbon.However, under the trend of carbon peak and carbon neutrality, determined transformation is the only way for cement enterprises to survive, and of course, it also needs to pay arduous efforts.Fortunately, at present, from the national level to the enterprise level, have begun to make efforts to reduce carbon emissions.China’s cement industry has serious overcapacity and prominent structural contradictions, which are the direct cause of the large carbon emission base and bring great pressure to the emission reduction work.At present, from the state to local governments, relevant policies have been issued to strictly control the “two high” projects, which are strictly forbidden to blindly launch projects, the supervision group’s continuous supervision and inspection, and the immediate closure of production lines with excess capacity…Both were among the first to curb the rise in carbon emissions at source.Compared with technical transformation with high technical content, staggered peak production is the most direct and fastest means to see the carbon reduction results.At present, the staggered peak production of cement enterprises has been spread to the whole country for many years, and has received remarkable results.During the 13th Five-Year Plan period, the cement industry benefited from the peaking production policy, reducing emissions of 1.53 billion tons of carbon dioxide, 53,400 tons of sulfur dioxide, 1.96 million tons of nitrogen oxide and over 100 million tons of coal, making a significant contribution to environmental governance, alleviating the pressure of overcapacity and improving economic benefits.Second, expand the field of new energy with wind, light, electricity, biomass and other replacement of raw coal fuel, for China’s cement leading enterprises have long been familiar with.Conch Cement has built 19 photovoltaic power stations and 3 energy storage power stations, with an annual power generation of 180 million KWH, creating the first benchmark enterprise of “zero outsourcing power” in the cement industry.Tapai, Shangfeng, Evergreen and other enterprises have also carried out the layout of photovoltaic energy storage projects, coal saving and emission reduction effect is increasingly significant.Tongling Zhongyang Conch biomass alternative fuel project is the first set of biomass alternative fuel system in the domestic cement industry. After the normal operation of the first phase of the project, it is expected to save about 49,000 tons of raw coal per year, and at the same time, it can dispose of biomass “waste” such as straw about 150,000 tons per year.Carbon capture, utilization and storage technology carbon capture, utilization and storage (CCUS), that is, the carbon dioxide emitted in the production process is purified, and then put into a new production process for recycling or storage.This is to recycle carbon dioxide and generate new economic benefits.The world’s first cement kiln flue gas CARBON dioxide capture and purification environmental protection demonstration project constructed by Conch was successfully put into operation in 2018, marking the first industrialization of carbon capture and utilization.The world’s first cement kiln exhaust carbon absorption brick production line has been successfully run in Huaxin Cement Co., LTD. It is the world’s first production line that uses cement kiln exhaust gas to produce concrete products. Taking the production line with an annual output of 100 million pieces of steam cured brick as an example, it uses 26,000 tons of carbon dioxide every year, and the annual carbon reduction will reach 52 million tons nationwide.Since 2019, Taiwan Mud has helped to treat domestic and industrial wastes with the high-temperature characteristics of 1,300 degrees of cement production process.Engineering waste soil in construction industry, steelmaking reduction slag in steel industry, calcium fluoride sludge in semiconductor manufacturing industry, waste pressure molding glue in semiconductor packaging industry and recycled granules in waste incineration industry have all become alternative raw fuels in cement production process.China Building Materials Continues to strengthen the comprehensive utilization of solid waste resources, increasing the proportion of slag, steel slag, fly ash and other industrial waste to replace natural mineral raw materials, and the annual consumption of solid waste is 120 million tons.The total installed capacity is 2,375 MEGAwatts, and the annual power generation capacity is 10.3 billion KWH, equivalent to saving 1.2 million tons of standard coal and reducing 6 million tons of carbon dioxide emissions.Five, enter the carbon market, manage carbon assets while focusing on energy conservation and emission reduction technology, cement enterprises should actively participate in carbon trading, use carbon financial tools to activate carbon assets, expand the growth point of enterprise profits.In August 2021, Conch Group and Shanghai Environment and Energy Exchange signed a cooperation agreement on carbon trading market capacity building and carbon management system construction in Shanghai, and jointly promoted the efficient and professional management of carbon assets through the construction of supporting system for the national carbon market.In September, Red Lion Holdings Group Co., Ltd. successfully issued 100 million yuan of carbon neutral bonds for the first private enterprise in China in the inter-bank bond market.2022 is a key year of the “14th Five-year Plan”, a critical year to promote high-quality development in an all-round way, and a year of “double carbon” reform in the cement industry.In the 2022 work planning of major cement enterprises, the “double carbon” has been put among the top priorities: In 2022, Conch Group raised the “double carbon” work to the height of enterprise survival, and formulated carbon emission reduction target value, road map and schedule.We will strengthen the innovation chain, improve the mechanism of three-carbon research institutes, and create more innovation consortiums.In 2022, China Building Materials will firmly follow the path of ecological priority, green and low-carbon development, and do a good job in carbon reduction, carbon sequestration and carbon management.We will accelerate the implementation of the “dual carbon” initiative, and accelerate the comprehensive use of green energy.In 2022, Red Lion Group will fully implement the “dual carbon” policy, vigorously promote the research and application of intelligent manufacturing, photovoltaic + energy storage, alternative fuels and other low-carbon technologies, and continuously improve the level of energy saving and carbon reduction.In 2022, Huaxin will continue to unswervingly adhere to the “green and low-carbon” development, take precise measures, make overall plans and steadily promote various work around the node target of the company’s low-carbon development and five-year doubling plan.Green mountains are gold and silver mountains, the future, will be the cement industry to actively respond to carbon peak carbon neutrality in the future, the cement market will also be a new shuffle and adjustment, cement enterprises only keep up with the trend of continuous optimization, improve the technical content, to implement energy conservation and emission reduction, to have a bright future of sustainable development.
