Globally, the Construction industry is responsible for over 30% of the extraction of natural resources, 25% of solid waste generated and 40% of Greenhouse Gases (GHG) emissions. Around a third of these emissions come from embodied carbon in construction. Cement and Steel are responsible for most of the embodied GHGs, representing >80% of the total. With recycling of cement and steel having a limited potential for further improving material efficiency, the focus is on replacing them with low-carbon alternatives and/or embedding them in reusable construction components. RECONSTRUCT will (i) develop low-carbon alternatives to Ordinary Portland Cement (OPC), to be used in both renovations and new buildings, and incorporate Construction & Demolition Waste (CDW) and other waste as much as possible, (ii) manufacture construction components that use such materials and are designed for modularity and dismantling so they can either be reused or easily disassembled and recycled, (iii) embed deconstruction in building design and construct circular low carbon buildings that produce near-zero CDW across their lifecycle. These objectives will become possible through (i) the digitization of construction materials, products and buildings, (ii) the extensive use of digital tools to support the design, construction and deconstruction phases of the circular building and (iii) the regionalization of the construction value chain through the creation of regional ecosystems of stakeholders covering all the aspects of circular construction. The RECONSTRUCT concept will be demonstrated by setting up to Territorial Circular Clusters, in Brussels and Barcelona, and using RECONSTRUCT's materials, components and innovative tools to design and construct two real-scale demonstrator buildings. By doing so, RECONSTRUCT aims to demonstrate its high impact potential (including a GHG reduction potential of 137,12 Mt CO2 per year, avoidance of 85 million tonnes of CDW per year and substitution of 197 Mt of OPC concrete per year) and its economic feasibility.

在全球范围内，建筑业占自然资源开采量的30%以上，产生的固体废物的25%和温室气体（GHG）排放量的40%。这些排放量中约有三分之一来自建筑中的隐含碳。水泥和钢铁产生了大部分的温室气体，占总量的80%以上。由于水泥和钢材的回收利用在进一步提高材料效率方面的潜力有限，因此重点是用低碳替代品取代它们和/或将它们嵌入可重复使用的建筑构件中。RECONSTRUCT将（i）开发普通波特兰水泥（OPC）的低碳替代品，用于翻新和新建筑，并尽可能多地纳入建筑和拆除废物（CDW）和其他废物，（ii）制造使用此类材料的建筑部件，并设计为模块化和拆卸，以便它们可以重复使用或易于拆卸和回收，（iii）在建筑设计中融入解构主义，建造循环低碳建筑，在整个生命周期内产生接近零的CDW。这些目标将通过以下方式实现：（i）建筑材料、产品和建筑物的数字化;（ii）广泛使用数字化工具，以支持循环建筑的设计、施工和拆除阶段;（iii）通过创建涵盖循环建筑所有方面的利益相关者区域生态系统，实现建筑价值链的区域化。RECONSTRUCT概念将通过在布鲁塞尔和巴塞罗那建立区域环形集群来展示，并使用RECONSTRUCT的材料，组件和创新工具来设计和建造两个真实规模的示范建筑。通过这样做，RECONSTRUCT旨在展示其高影响潜力（包括每年减少1.3712亿吨CO2的温室气体排放潜力，每年避免8500万吨CDW，每年替代1.97亿吨OPC混凝土）及其经济可行性。
