Embedding the Circular Economy in EPDs

The concept of a circular economy in construction revolves around rethinking the traditional linear model of ‘take, make, dispose’ and transforming it into a sustainable cycle of ‘reuse, recycle, and recover’.

This approach emphasizes minimizing waste, extending the lifecycle of materials, and reusing resources to create a more sustainable and environmentally friendly construction industry.

By prioritizing sustainable materials, efficient design, and innovative recycling methods, the circular economy aims to reduce environmental impact and foster a more sustainable future in construction. This shift not only benefits the environment but also presents new economic opportunities and encourages innovation in building design and material usage.

Environmental Product Declarations (EPDs) have evolved to become crucial in providing environmental information based on the life cycle of products. Globally, they are being integrated into policy frameworks to support circular economy principles.

In 2022, the EPD platform’s Circular Economy Task Group was established to create a standardized approach for assessing products’ alignment with circular principles. The task group aims to integrate these standards into EPDs by early 2025.

1. Develop recognized methods for circularity assessment.
2. Propose integration of circularity information in EPDs.
3. Create verification guidelines for circularity in construction products.

The Task Group analyzed existing circular economy methods to develop a comprehensive circularity assessment framework.

Comparative Analysis of Circularity Methods

• Material Circularity Indicator (MCI) by Ellen MacArthur Foundation
• New Circularity Index by NLX and ICMQ

A pilot study with a sliding door manufacturer highlighted the usability and data collection aspects of the MCI and NLX & ICMQ methods. Future steps include further engagement with Green Building Councils and manufacturers for method refinement.

Integrating circular economy principles in EPDs is vital for aligning construction projects with global sustainability goals. The Circular Economy Task Group’s efforts will ensure EPDs accurately reflect a product’s sustainability credentials, leading the way to a resource-efficient future.
