Circular economy research focuses on transforming linear “take make dispose” systems into closed loops that keep materials, products and value in use for as long as possible. It integrates ideas from industrial ecology, ecological economics, design, and systems thinking.

A core theme is decoupling economic activity from resource extraction and environmental harm. Studies highlight strategies such as product life extension, reuse, repair, remanufacturing, recycling, and new business models like product as a service. These approaches aim to reduce waste, conserve resources and lower greenhouse gas emissions while maintaining or improving economic performance.

Research emphasizes design for circularity, where products are created to be durable, modular, easy to disassemble and made from materials that can be safely cycled. Attention is also given to biological and technical cycles, in which biodegradable materials safely re enter natural systems and technical materials circulate in industrial processes at high quality.

Scholars analyze enabling conditions: regulation, economic incentives, digital tracking of materials, collaboration across value chains and consumer behavior. Case studies explore sectors such as electronics, construction, plastics and textiles, revealing both potential and practical barriers, including technological limitations, current pricing of virgin materials, and institutional inertia.

Work on metrics and indicators seeks to measure circularity, from material flow analysis to life cycle assessment and broader sustainability indicators. Recent research stresses that a circular economy is not automatically sustainable: rebound effects, social equity and planetary boundaries must be considered. The emerging view is that circularity is a key part of a broader transition to sustainable, resilient and low carbon societies.
