以废代原”减碳更实在 | 大家谈 如何当好“碳路先锋

Core Viewpoint - The chemical industry is positioned as a key player in achieving carbon peak and carbon neutrality in China's green low-carbon economy, emphasizing the potential for waste utilization to balance carbon reduction and development [1][2] Group 1: Carbon Reduction Strategies - The chemical industry can leverage waste materials to replace traditional raw materials, thus achieving both carbon reduction and economic development [1] - Shanxi Huayu Energy Chemical Co., Ltd. transforms gasification coarse slag into a substitute for red clay in brick production, saving 10,000 tons of standard coal annually and reducing CO2 emissions by 24,500 tons [1] - The company also utilizes low-sulfur waste alcohol, distillation waste gas, and dried sludge in boilers, saving 1,000 tons of standard coal per year [1] Group 2: Utilization of By-products - Chemical enterprises can synchronize carbon reduction and cost reduction by effectively utilizing by-products [2] - The Luan Chemical Fengxi Group's project produces 5 tons of low-grade steam per hour as a by-product, which was previously wasted; after implementing a technology upgrade, this steam generates 9,600 kWh of electricity daily, reducing CO2 emissions by approximately 7.06 tons per day [2] - The project also recycles condensate for reuse in the system, reducing desalination water preparation and achieving dual cost savings [2]
