The construction industry significantly impacts the environment through natural resource depletion and energy consumption, leading to environmental degradation. Circular Economy (CE) material efficiency strategies-such as material reuse, design for disassembly, prefabrication, and recycling-offer promising solutions for reducing resource consumption and waste. This paper explores stakeholders' perspectives on the costs and benefits of implementing CE material efficiency strategies in the construction industry, using the 3-R (Reduce, Reuse, Recycle) framework. By analyzing data from 382 participants, it assesses perceptions of costs and benefits, uncovering regional differences. The findings highlight that studied European stakeholders prioritize reuse and design for disassembly, while studied non-European countries focus on offsite production and material reuse optimization. Despite these differences, both groups view waste reduction as a key benefit, due to the cost savings it provides. By highlighting regional drivers and barriers to CE adoption, this research establishes a foundation for developing targeted policies and collaborative strategies to advance CE implementation in construction worldwide.
建筑业通过自然资源消耗和能源消耗对环境产生重大影响，导致环境退化。循环经济（CE）的材料效率策略，如材料再利用、可拆卸设计、预制和回收，为减少资源消耗和废物提供了有前景的解决方案。本文使用3R（减少、再利用、回收）框架，探讨了利益相关者对建筑业实施循环经济材料效率策略的成本和收益的看法。通过分析382名参与者的数据，评估了对成本和收益的认知，发现了地区差异。研究结果表明，参与研究的欧洲利益相关者将再利用和可拆卸设计列为优先事项，而参与研究的非欧洲国家则侧重于场外生产和材料再利用优化。尽管存在这些差异，但两组都将减少废物视为一项关键收益，因为这能节省成本。通过突出采用循环经济的地区驱动因素和障碍，本研究为制定有针对性的政策和合作策略奠定了基础，以推动全球建筑业循环经济的实施。
