HOOP: Guidelines for Authorities
Updated on 29.07.2025
The HOOP Guidelines will guide you through the key steps to identify, design, and implement innovative valorisation routes for urban biowaste and wastewater sludge. It summarises key recommendations, as well as relevant resources and tools that can be used to produce high-quality biowaste-based products and materials. The HOOP Guidelines also aims to guide the readers through the different HOOP resources and tools available in the HOOP Urban Circular Bioeconomy Hub.
Relevance for Circular Systemic Solutions
The HOOP Guidelines target the urban biowaste and wastewater value chains, focusing on their prevention, collection, treatment, and valorisation into high-value bioproducts. The guidelines offer practical steps and tools for assessing local baselines, selecting appropriate biowaste valorisation technologies, identifying funding opportunities, and engaging citizens and stakeholders.
Notable tools include the HOOP Bio-Circularity Label for self-assessment, project maturity evaluation tools, and examples of high-TRL technologies ready for deployment. These recommendations are crucial for developing Circular Solutions by supporting collaboration across sectors to identify feedstock availability, engage stakeholders, and align technologies with local needs.
The guidelines enhance all phases (map, design, and implement) by providing a structured methodology, relevant KPIs, and real-world examples to ensure tailored, feasible, and accepted solutions.
