循环经济已成为欧洲政策竞技场的核心，各成员国推动了一系列倡议和计划，从传统的线性经济转向循环经济。这对建筑部门尤其重要，因为建筑部门是废物产生量最大的部门，也是资源消耗的主要原因之一。本文的目的是分析目前的循环战略的应用水平，确定相关的障碍和驱动程序，通过采访建设利益相关者在五个欧洲国家，比利时（弗兰德斯），荷兰，英国，丹麦，和意大利。该分析侧重于建筑层面，并评估了在三个关键领域：资源和废物管理、可逆建筑设计以及建筑价值链运营商网络化业务中，循环战略在当前政策和实践中的应用水平。结果突出了所分析的国家目前采用的不同和分散的循环战略，突出了欧洲联盟委员会推动的更有效和协调的行动和政策的必要性。特别是，目前的立法框架促进废物管理战略，更侧重于回收做法，而不是再利用或资源管理。可逆建筑的设计策略通常是由私人倡议，由市场竞争驱动，而不是由公共激励。循环型商业模式的应用和价值链运营商之间循环网络的建立仍然缺乏。此外，很少使用生命周期工具来评估循环战略的环境效益（可持续性）。通过对受访建筑行业主要参与者分析和要求的各国循环经济战略当前应用情况进行比较，提出了一些建议，包括需要在政策、实践和使能工具（数字数据、平台、可追溯性）方面加强国际协调。需要改进立法框架和做法。研究的未来发展特别关注数字支持工具和环境评估（LCA），循环关系和商业模式以及与使能方面相关的新专业知识的定义/培训等领域。
Circular economy has become central in the European policy arena, and the Member States have promoted a number of initiatives and programs to shift from their traditional linear economy towards a circular economy. This is particularly relevant for the construction sector, which is the highest producer of waste and one of the main causes of resources consumption. The paper objective is to analyse the present level of application of circularity strategies, identifying the related barriers and drivers, through interviews with building stakeholders across five European countries, Belgium (Flanders), Netherlands, United Kingdom, Denmark, and Italy. The analysis focuses on the building level and assesses the level of application in current policies and practices of circular strategies in three key field: resource and waste management, design for reversible building, and business for the networking of operators in the construction value chain. The results highlight the different and fragmented circular strategies currently applied in the analysed countries analysed, highlighting the need for more effective and coordinated actions and policies promoted by European Commission. In particular, the current legislative framework promotes the waste management strategies, focusing more on recycling practices than on reuse or resource management. The design strategies for reversible building are generally in private initiatives, driven by market competitions, rather than by public incentives. The application of circular business models and the creation of circular networks among the operators of the value chain is still lacking. Furthermore, the use of life-cycle tools to assess the environmental effectiveness (sustainability) of circular strategies is rarely applied. The recommendations that emerged from the comparison of the current applications of circular economy strategies across the countries analysed and demanded by key players in the construction sector interviewed, include the need for greater international coordination in terms of policy, practices and enabling tools (digital data, platforms, traceability). Improvements in both the legislative framework and practices are needed. Future development of research regards, in particular, the fields of digital supporting tools and environmental assessment (LCA), circular relationships and business models and the definition/training of new expertise related to enabling aspects.
