Short Abstract

This contribution provides insights on citizen science initiatives in waste valorisation as collected within the EU-funded AGRIMA project. The contribution will share reflections on types of waste and technologies used, as well as levels of citizen participation in the circular economy transition.

Abstract

The transition to a circular economy requires not only technological innovation but also active citizen involvement. Yet the role of citizens in waste valorisation is often underexplored. The AGRIMA project (Erasmus+ KA2, 2024–2026, https://web2learn.eu/portfolio/agrima/) addresses this gap by documenting and analysing citizen science (CS) projects on waste management and valorisation in the agri-food sector.

In particular, the AGRIMA collection of such CS projects brings together diverse initiatives across Europe, focusing on four key features: (i) levels of citizen participation, from data gathering to co-creation of solutions; (ii) technologies used, ranging from composting to AI and machine learning; (iii) types of waste valorised; and (iv) fields of application, such as agriculture, pharmaceutics, and packaging. This systematic mapping provides insights into how CS initiatives on waste valorisation contribute to the circular economy by producing relevant data, raising awareness, and fostering behavioural change. It also reveals the challenges of scaling up, ensuring inclusivity, and embedding citizen-driven practices into policy frameworks.

By showcasing the AGRIMA collection, this contribution aims to demonstrate that CS can act as a catalyst for waste reduction, resource efficiency, and civic participation in sustainability transitions. The presentation will discuss lessons learned from the collected projects, as well as opportunities for expanding citizen involvement in circular economy strategies. This contribution presents results of Work Package 4 Activity 1 (WP4A1, led by Web2Learn) of the EU-funded project AGRIMA (Agri-food Waste Management for Sustainable bio-economy through Higher Education curricula and upskilling).
