In the age of rapid global change and heightened awareness of sustainable business practices, the transition to a circular economy has become increasingly crucial for companies looking to thrive in a competitive market. However, our extensive engagement with businesses has revealed a recurring challenge: many companies lack clarity on their current stage of circular economy adaptation and struggle to identify potential opportunities for improvement. This observation aligns with barriers identified in the existing literature, demonstrating the need for a comprehensive and user-friendly tool that enables companies to navigate the complexities of the circular economy. To address this gap, we have aligned with Loughborough Business School, co-developed the Circular Economy Assessment Tool — a groundbreaking solution designed to assist businesses in evaluating their current practices, quantifying their results, and identifying areas for growth.
