Real-life testing of a closed-loop kitchen bio-waste system in the Górnośląsko-Zagłębiowska Metropolia (GZM), covering resident engagement, separate household collection, collection validation, transport conditions and analysis of the municipal organic kitchen waste stream. The pilot covers about 4 000 households in multi-family buildings in Chorzów.
To test and validate an effective closed-loop model for separate kitchen bio-waste collection in multi-family housing and use the results to refine the GZM climate transition roadmap.
Górnośląsko-Zagłębiowska Metropolia (GZM): pilot lead and metropolitan authority.
Urban Technology Alliance: roadmap development, pilot-related coordination and methodological support through the MICAD project.
GZM is one of five metropolitan authorities in MICAD (Metropolitan Inclusivity in Climate and Digital Transitions), each developing a local climate and digital transition roadmap with a common framework from Kentyou and UTA.
GZM is linking its roadmap to a bio-waste collection pilot for 4 000 households in multi-family buildings in Chorzów. In September 2026, its updated roadmap was awaiting internal approval.
Resident awareness and education, household source separation, dedicated collection arrangements, monitoring of collection quality, transport to treatment facilities, waste-stream analysis and subsequent valorisation of bio-waste.
Validated procedures for separate kitchen bio-waste collection; improved understanding of resident behaviour and collection quality; evidence on logistics and waste-stream composition; and practical input for the GZM Kitchen Bio-Waste Closed-Loop Roadmap.
Expected benefits include increased separate bio-waste collection, reduced disposal of kitchen waste in mixed waste, improved waste-stream quality, stronger resident engagement and better conditions for circular use of bio-waste-derived products.
Pilot results will inform the final GZM roadmap and may support wider implementation of the closed-loop model across GZM municipalities and other metropolitan areas.
