This Standardization Roadmap aims to provide an overview of the status quo of standardization in the field of the circular economy, to describe the requirements and challenges for seven key topics, and to identify possible needs for future standards and specifications.

The HOOP project has provided Project Development Assistance to eight lighthouse cities and regions, supporting them with the development of large-scale urban circular bioeconomy initiatives focusing on making bio-based products from urban biowaste and wastewater. The partners have developed a suite of open-source tools to help cities and regions launch urban circular bioeconomy projects.
