The UK construction sector accounts for around 40% of the national raw materials use (Eurostat, 2019). The sector produced over 10 million metric tons of carbon dioxide emissions in 2021, of which 80% came from materials use and on-site activities. This was an increase of about 12 percent from the previous year and accounted for some 2.4 percent of the total UK carbon dioxide emissions that year (Statista, 2022). As a result, it is critical to transition from a linear to a circular economy in the UK construction industry to decarbonise in line with the national emission reduction targets of 68% by 2030 and 78% by 2035\.Within the construction industry in the UK, aggregates constitute 60% of material usage, followed by concrete at 22%, asphalt at 10%, and iron and steel at 4%. Building and demolition site waste accounts for 62% of the total waste generated in the UK. This construction waste consists mainly of reusable building components and debris from construction activities. Concrete and rubble can often be recycled into aggregate for reuse. Wood can be recycled into engineered wood products like furniture. Metals like steel, copper, and brass are also valuable resources to recycle or reuse.Reusing high-value waste construction materials from building or demolition projects that otherwise would be discarded as waste is a key strategy for achieving a circular construction economy. However, this potential for reuse is often hindered by a critical access and real-time information gap on construction waste around the country. Against this backdrop, this project aims to initiate a digital platform that fosters the attainment of net zero in the UK construction sector by minimizing building materials waste through a recycle or reuse framework. It has the following specific objectives:1\. Use open-source data sets to synthesise a framework for the characterisation and assessment of recovered materials for reuse or recycling, and document well-established processes for generating and using such information.2\. Use the framework from the above to drive circularity for Net Zero in construction by developing an online marketplace for stakeholders to procure and trade construction waste.3\. Pilot the aforementioned marketplace with a select group of participants. This is to include construction companies, contractors, recycling facilities, and potential buyers, ensuring that participants represent diverse segments of the construction industry.

英国建筑业约占全国原材料使用量的 40%（欧盟统计局，2019 年）。 2021 年，该行业的二氧化碳排放量超过 1000 万吨，其中 80% 来自材料使用和现场活动。这比上一年增加了约 12%，约占当年英国二氧化碳排放总量的 2.4%（Statista，2022 年）。因此，英国建筑业从线性经济向循环经济转型，以实现脱碳，以符合到2030年68%和2035年78%的国家减排目标至关重要。 ，骨料占材料用量的 60%，其次是混凝土，占 22%，沥青占 10%，钢铁占 4%。建筑和拆除工地废物占英国产生的废物总量的 62%。这种建筑垃圾主要由可重复使用的建筑构件和建筑活动产生的碎片组成。混凝土和碎石通常可以回收成骨料以供再利用。木材可以回收制成家具等工程木制品。钢、铜和黄铜等金属也是回收或再利用的宝贵资源。对建筑或拆除项目中原本会作为废物丢弃的高价值废弃建筑材料进行再利用是实现循环建筑经济的关键战略。然而，这种再利用的潜力往往受到全国各地建筑垃圾关键获取和实时信息差距的阻碍。在此背景下，该项目旨在启动一个数字平台，通过回收或再利用框架最大限度地减少建筑材料浪费，从而促进英国建筑行业实现净零排放。其具体目标如下： 1．使用开源数据集综合一个框架，用于表征和评估回收材料以供再利用或回收，并记录生成和使用此类信息的完善流程。2\。使用上述框架，通过开发供利益相关者采购和交易建筑垃圾的在线市场，推动建筑领域净零的循环。3\。与一组选定的参与者一起试点上述市场。这包括建筑公司、承包商、回收设施和潜在买家，确保参与者代表建筑行业的不同领域。
