A new version of the Circularity Package has been released after the database and methodology went through a successful third party review by Jim Goddin, co-author of the ISO 59020:2024 for measuring and assessing circularity performance and the Material Circularity Indicator (MCI). You can read the review statement here: /wp-content/uploads/2026/08/Circularity-Package-Review-Statement-2026.pdf
Main changes compared to v3
- Updated the script that helps calculate MCI indicator (integrated within the database)
- Wood from sustainable production is now traced with the indicator for renewable material (M_renewable) rather than virgin material (V).
- Methodology is third party verified.
