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，建筑行业消耗了 30% 以上的自然资源、产生了 25% 的固体废物以及 40% 的温室气体 (GHG) 排放量。其中大约三分之一的排放来自建筑中的隐含碳。水泥和钢铁造成了大部分温室气体排放，占总量的 80% 以上。由于水泥和钢材的回收利用进一步提高材料效率的潜力有限，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组件中。 RECONSTRUCT 将 (i) 开发普通波特兰水泥 (OPC) 的低碳替代品，用于翻修和新建建筑，并尽可能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组件，并设计为模块化和可拆卸的，以便它们可以重复使用或易于拆卸和回收，(iii) 将解构主义嵌入建筑设计和施工中 循环低碳建筑在其整个生命周期中产生接近于零的车辆碰撞重量。这些目标将通过以下方式实现：（i）建筑材料、产品和建筑的数字化，（ii）广泛使用数字工具来支持循环建筑的设计、施工和解构阶段，以及（iii）通过创建涵盖循环建筑各个方面的利益相关者的区域生态系统来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领土圆形集群，并使用 RECONSTRUCT 的材料、组件和创新工具来设计和建造两座真实规模的示范建筑来展示。 RECONSTRUCT 旨在通过这样做来展示其高影响潜力（包括每年 137.12 公吨二氧化碳的温室气体减排潜力、每年避免 8500 万吨 CDW 以及每年替代 197 公吨 OPC 混凝土）及其经济可行性。
