Group 1 - Cement companies are actively responding to the national "dual carbon" strategy by implementing ultra-low emissions and energy-saving carbon reduction modifications, utilizing distributed photovoltaic power generation and waste heat power generation technologies as effective means for energy conservation and emission reduction [1][2][3] - Waste heat power generation technology recovers medium and low-temperature waste heat from kiln emissions to generate electricity, converting thermal energy produced during clinker production into electrical energy, thus achieving resource recycling and reducing carbon emissions [1] - In 2024, Taipai Group reported a waste heat power generation output of 34.374 million kilowatt-hours, resulting in a reduction of approximately 330,000 tons of carbon dioxide emissions [1] - Shengfeng Cement utilized waste heat power generation to produce 473 million kilowatt-hours in 2024, leading to a reduction of 389,800 tons of carbon dioxide emissions [2] - Yatai Group implemented pure low-temperature waste heat power generation measures, reducing carbon dioxide emissions by 115,600 tons in 2024 [3] - Wanyanqing has ten operational waste heat power generation units with a total installed capacity of 80.30 MW, which can meet about 50% of the electricity demand for the company's kiln system [3] - A waste heat power generation project by Xinjiang Tianshan Cement, contracted by China National Materials Group, has a capacity of 10 MW and is expected to generate 44.08 million kilowatt-hours annually, reducing carbon emissions by an average of 3,700 tons per year [3] Group 2 - Analysts indicate that waste heat power generation has become an important factor for downstream concrete and construction companies in "green procurement" and ESG ratings, enhancing the image of cement companies and increasing their social responsibility [3]
