建筑物和施工被认为是应用循环经济原则创造和获取价值的最大潜力之一。为实现这一目标，需要在回收、再制造和再利用使用寿命结束的结构产品（如钢材、砖、混凝土）方面进行根本性转变，这些产品占材料的最大比例。与此同时，这些产品必须在为随后的拆除和拆卸而设计的新建筑和基础设施中重新使用。REBUILD是一个为期3年的英国研究项目，旨在应对这一挑战。基于我们的案例研究城市之一，提出了量化建筑物材料强度（存量和流量评估）的初步研究结果。从水泥砂浆中分离和回收砖的新技术的结果显示了技术可行性和保持结构性能的能力。详细介绍了下一阶段的规模这项工作和技术的分离和回收钢材和混凝土的简要说明。还描述了生命周期评估、价值流映射和为新形式的循环建筑和建筑系统创建产品的后续阶段。本文的结论是，虽然在回收结构产品方面存在相当大的挑战，但重新设计的循环建筑和建筑系统可以改变使用寿命结束的建筑物的价值，并为循环创新和材料和产品的流通提供新的机会。
Buildings and construction have been identified as having one of the greatest potential for value creation and capture from the application of circular economy principles. To achieve this requires a fundamental transformation in the recovery, remanufacture and re-use of end of service life structural products such as steel, bricks, concrete which make up the largest proportion of materials. At the same time these products must be re-used in new buildings and infrastructure designed for subsequent deconstruction and disassembly. REBUILD is a 3 year way UK research project to address this challenge. Initial findings on quantifying the material intensity of buildings (stock and flow assessment) are presented based on one of our case study cities. Results from new techniques to separate and reclaim bricks from cement mortar shows technical feasibility and ability to retain structural performance. Details on the next stage of scaling this work and techniques for separating and reclaiming steel and concrete are briefly described. Subsequent stage of life cycle assessment, value stream mapping and creating products for new forms of circular building and construction systems are also described. The paper concludes that whilst there are considerable challenges in reclaiming structural products that re-designed circular building and construction system could transform the value of end of service life buildings and the offers new opportunities for circular innovation and the circulation of materials and products at their highest value for the longest period.
