Reclinker是一家将建筑拆除废料重新转化为水泥的初创公司，已在A轮融资中筹集1000万英镑。公司将利用这笔资金，从试验阶段迈向在加的夫全面商业化生产。公司周一表示，其工艺能将水泥排放量减半，且成本与传统水泥相同。
Reclinker, a startup that turns demolition waste back into cement, has raised £10m in a Series A round. It will use the money to move from trials to full commercial production in Cardiff. The company said on Monday that its process cuts cement’s emissions in half, at the same cost as conventional cement.
清洁增长基金和AP Ventures联合领投了本轮融资。威尔士开发银行和Kibo Invest参投，零碳资本和剑桥企业等现有投资者也继续跟投。首席执行官比尔·约斯特表示，本轮融资获得超额认购。
Clean Growth Fund and AP Ventures co-led the round. The Development Bank of Wales and Kibo Invest joined, along with existing investors Zero Carbon Capital and Cambridge Enterprise. Chief executive Bill Yost said the round was oversubscribed.
约斯特说：“本轮融资获得超额认购，是一个有力信号，表明英国投资者确实重视脱碳。”
“This oversubscribed round sends a strong signal that UK investors are serious about decarbonisation,” Yost said.
无需窑炉的水泥 据Reclinker称，水泥造成的排放约占全球二氧化碳排放量的7%，约为航空业的三倍。其中大部分来自熟料的生产，而熟料是水泥的关键成分。窑炉通过加热石灰石来生产熟料，石灰石本身以及为窑炉提供燃料的化石燃料都会释放二氧化碳。
Cement without a kiln Cement causes about 7% of global CO₂ emissions, roughly three times as much as aviation, according to Reclinker. Most of it comes from making clinker, cement’s key ingredient. Kilns heat limestone, which releases CO₂ from the rock and from the fossil fuels that fire the kilns.
剑桥大学的研究人员开发了Reclinker的工艺，并在《自然》杂志2024年发表的一篇论文中对其进行了介绍。该工艺从拆除建筑中回收废旧水泥浆体，随后将其送入原本用于回收废钢的电弧炉，在炉中重新转化为熟料。
Researchers at the University of Cambridge developed Reclinker’s process and described it in a 2024 paper in Nature. It recovers old cement paste from demolished buildings. That paste then goes into the electric arc furnaces that already recycle scrap steel, where it turns back into clinker.
这种熔炉能够同时生产再生钢和新水泥。整个工艺不需要窑炉，也不需要开采石灰石或使用化石燃料供热。Reclinker预计，初期可实现50%的减排，随着技术扩大应用，减排幅度还会进一步提高。TNW尚未对这些数据作出独立核实。
The furnace makes recycled steel and new cement at the same time. The process needs no kiln, no quarried limestone and no fossil-fuel heat. Reclinker expects a 50% cut in emissions at first, and more as the technology scales. TNW has not independently verified these figures.
其他重工业也在将自身废弃物回收利用，制成新材料。保时捷已利用由自家废旧电池包制成的再生正极材料，制造出一块电池电芯。
Other heavy industries are also recycling their own waste into new material. Porsche has built a battery cell with a recycled cathode, made from its own old packs.
从试验走向销售，Reclinker已在7 Steel UK位于卡迪夫的工厂生产了数千吨产品，并实现了首笔商业销售，瞄准供应缺口。长期以来，混凝土制造商一直使用高炉矿渣配制低碳水泥。随着钢铁企业逐步弃用高炉，这种矿渣正趋于枯竭。
From trials to sales Reclinker has made thousands of tonnes of its product at 7 Steel UK’s plant in Cardiff. It has also secured its first commercial sales. It targets a gap in supply. Concrete makers have long used blast-furnace slag for low-carbon cement blends. That slag is running out as steelmakers move away from blast furnaces.
威尔士开发银行的Gareth Mayhead表示：“通过与专业气候技术投资者共同投资，我们正在帮助Reclinker在当地建立业务并扩大发展。”
“By investing alongside specialist climate technology investors, we’re helping Reclinker establish and grow its presence here,” said Gareth Mayhead of the Development Bank of Wales.
通过英国创新署的“先进市场承诺”计划，大型混凝土用户表示，计划在未来五年内采用更多低碳材料。除卡迪夫外，这笔资金还将帮助Reclinker将其工艺推广至欧洲和美国其他电弧炉所在地。
Through the Innovate UK Advance Market Commitment, large concrete users have said they plan to use more low-carbon materials. They aim to do so over the next five years. Beyond Cardiff, the money will help Reclinker take its process to other electric arc furnace sites in Europe and the US.
今年秋季，建筑科技领域已完成多轮大额融资。9月，软银向自主建筑公司ASI投资2.25亿美元；就在一个月前，软银领投了Gravis Robotics的2亿美元A轮融资。
Construction technology has drawn large rounds this autumn. SoftBank invested $225m in autonomous construction firm ASI in September, a month after Gravis Robotics raised a $200m Series A led by SoftBank.
清洁增长基金投资合伙人Stephen Price表示：“水泥是最难实现脱碳的行业之一，其排放深度嵌入工艺化学反应和能源使用之中。”
“Cement is one of the most challenging sectors to decarbonise, with emissions deeply embedded in both process chemistry and energy use,” said Stephen Price, investment partner at Clean Growth Fund.
