Circular Economy Strategies for Reducing Environmental Footprints: Global Policies, Practices, and Barriers

Unofficial AI-generated summary based on the public title and abstract. Not an official translation.

🔬研究者:This review offers a structured synthesis of barriers and measurement challenges in circular economy, serving as a foundational reference for designing empirical studies on circularity outcomes and policy effectiveness.

🏢実務担当者:Corporates can leverage the identified leverage points and barrier analysis to refine circularity strategies in product design, supply chain, and waste management, supporting alignment with emerging disclosure standards on resource use.

🏛政策担当者:Policymakers can use the integrative framework to assess the effectiveness of existing policy instruments like EPR and eco-design requirements, and to design evidence-based interventions that address technological and economic constraints.

The circular economy is an innovative concept of both production and consumption. It can reduce wastage, preserve resources, and minimize environmental effects with the help of recycling, recovering resources, and extending the life of products. It works as a pathway to reduce environmental footprints by redesigning production-consumption systems. This review critically examines global circular economy strategies, policy approaches, and persistent barriers that shape environmental footprint outcomes across major sectors. Drawing on a structured narrative review and thematic synthesis, we integrate findings on key circular economy practices, Eco-design, product life extension, reuse, re-manufacturing, recycling, and resource recovery, and assess how they interact with policy instruments such as extended producer responsibility, eco-design requirements, and waste governance reforms. The analysis highlights that reported benefits (e.g., reduced material throughput, waste generation, and emissions) are frequently constrained by technological limitations (complex material streams, low-quality recyclate, energy-intensive processing), economic conditions (high upfront costs, weak markets for secondary materials, commodity price volatility), and institutional and behavioral factors (regulatory fragmentation, limited enforcement capacity, low consumer acceptance). We further synthesize methodological challenges in measuring “circularity” and footprint reductions, emphasizing boundary choices, rebound effects, and trade-offs such as increased energy demand or land and water pressures in bio-based substitution. By linking circular economy strategies, barriers, and outcomes in an integrative conceptual framework, the review clarifies why circular transitions often deliver partial gains and identifies leverage points for scaling effective, evidence-based policy and practice.
