清捕零碳 CLEANCO2 清捕零碳的碳捕集利用與封存技術的創新之處？ How Innovative is the Technology of Carbon Capture, Utilization, and Storage (CCUS)? 1 循環利用建築廢物 發展項目在建造過程中產生廢棄混凝土，清捕零碳將這 些廢棄混凝土破碎成骨料，並通過名為「二氧化碳礦化 強化工藝」的技術，製成低碳 RCA ，以代替混凝土原料。 低碳 RCA 的特性較傳統骨料優勝，有顯著的減排潛力。 Upcycle Construction Waste Waste concrete from development projects is crushed into aggregate and used for low carbon RCA through a carbon dioxide mineralization process. The low carbon RCA has significant potential to reduce emissions compared to normal aggregate when used as raw material for concrete. 2 源頭着手減少隱含碳排放 清捕零碳通過使用工業副產品粉煤灰和高爐渣粉代替 水泥，並以其專有的「二氧化碳礦化養護工藝」打造 「固碳混凝土實心磚」，其隱含碳排放預期將較傳統 燒結磚低 87.5 ％。 Reduce Embodied Carbon Emissions at Source CLEANCO2 low carbon concrete bricks use cement, fly ash and other solid waste together with CLEANCO2’s carbon dioxide mineralization process. The embodied carbon emissions of the low carbon concrete bricks are expected to be 87.5% lower than conventional shale bricks. 清捕零碳開發的技術源自浙江大學清潔能源利用 國家重點實驗室（ CEU ）。為響應國策， 2020 年清 捕零碳與 CEU 展開合作，建設了「浙江大學― 清捕零碳二氧化碳礦化利用技術聯合研發平台」， 這是中國首個可實現大規模工業生產驗證的二氧 化碳礦化利用試驗基地。 產品自身 減少碳排放 Built-in carbon emissions reduction capabilities 提升養護效率 降低成本 Improve maintenance efficiency and reduce costs 有效封存 利用廢棄 CO 2 Effective storage and utilization of waste CO 2 實現碳滙增加 額外收益 Achieve carbon sequestration to increase additional income 工業廢料 循環利用 Recycle industrial waste CO CO CO 87.5 % RCA % The technology developed by CLEANCO2 originated from the State Key Laboratory of Clean Energy Utilization (CEU) of Zhejiang University. In 2020, CLEANCO2 and CEU jointly built the “Zhejiang University-CLEANCO2 United Laboratory of CO 2 Mineralization Utilization Technology”, the first CO 2 mineralization utilization experimental base in mainland China, with the potential to achieve large- scale industrial production globally. 低碳 RCA 的特點 The Feature of RCA 5 專 題 故 事 F E A T U R E S T O R Y
