Current European policies identify the efficient management of Construction and Demolition Waste as a priority area. With regard to this, circular economy principles and present research trajectories encourage the less demanding manufacturing patterns as the ones enhancing resource efficiency, recognising the advantages of reusing as compared to recycling. However, the heterogeneous nature of EU norms concerning reclaimed building elements generates multiple inconsistencies. Uncertainties related to the waste management process, together with a legal vacuum, prevent reuse strategies from spreading, affecting both market competitiveness and its shift towards the sustainable resource management.

Starting from the European regulatory framework for reclaimed products and components in the architectural perspective, the paper discusses possible improvements towards a more circular built environment. It analyses how existing legal vacuums and inconsistencies prevent the implementation of reuse processes in the architectural field, adding barriers to a value chain already lacking driving forces. The examined regulatory context highlights how the reuse of building elements is subordinate not only to proper deconstruction activities, but also to the uncertain application of the CE marking and the unclear requirements for the element specific use. As a consequence, the legal framework worsen the existing obstacles to the use of reclaimed elements: the results show how time frames, costs, performance assessment, and end users perception are the more involved criticalities in the conflict between the enactment of reuse processes in architecture and the related regulatory context. The discussion reports possible actions and improvements on the regulatory and policy levels to simplify the procedures for architectural reuse practices. It also highlights how academic and professional research could represent a lever in promoting innovative and site-specific strategies fostering the reuse of building elements as a sustainable process.

当前的欧洲政策将建筑和拆除废物的有效管理确定为优先领域。在这方面，循环经济原则和目前的研究轨迹鼓励要求较低的制造模式作为提高资源效率的模式，并认识到再利用与回收相比的优势。然而，欧盟关于回收建筑元素的规范的异质性产生了多种不一致。与废物管理过程相关的不确定性以及法律真空，阻止了再利用策略的传播，影响了市场竞争力及其向可持续资源管理的转变。

从建筑角度对回收产品和组件的欧洲监管框架开始，本文讨论了朝着更加循环的建筑环境可能进行的改进。它分析了现有的法律真空和不一致如何阻止在建筑领域实施重用过程，为已经缺乏驱动力的价值链增加障碍。审查的监管背景强调了建筑元素的再利用如何不仅服从于适当的解构活动，而且还服从于 CE 标志的不确定应用和对元素特定用途的不明确要求。因此，法律框架加剧了使用回收元素的现有障碍：结果显示了时间框架、成本、性能评估、在架构中重用过程的制定与相关监管环境之间的冲突中，最终用户的看法是更重要的关键。讨论报告了在监管和政策层面上可能采取的行动和改进，以简化架构重用实践的程序。它还强调了学术和专业研究如何成为促进创新和特定地点战略的杠杆，促进建筑元素的再利用作为一个可持续的过程。
