# Metlen Protos energy recovery facility commissioning > Live situation record from CLSTR: https://clstr.news/situations/metlen-protos-energy-recovery-facility-commissioning > Updated: 2026-08-24T04:15:35.000Z. Sources: 7. Developments: 2. Metlen has reached a significant milestone at the Protos Energy Recovery Facility (ERF) in Cheshire, United Kingdom, by achieving ‘first fire on waste’. This event marks the beginning of the final stages of hot commissioning for the plant. Developed for Encyclis, the facility is designed to process 500,000 tonnes of non-recyclable waste per year. Once fully operational, it is expected to generate up to 49.9MW of electricity, enough to power roughly 90,000 homes. The project supports the circular economy by extracting ferrous and non-ferrous metals and converting bottom ash into secondary aggregates for construction. This project represents Metlen’s first venture into Waste-to-Energy. Its development involved overcoming various obstacles, including the energy crisis, inflation, and supply chain disruptions. The successful milestone also serves to validate Metlen’s strategic restructuring and the integration of its former M Renewables and M Power Projects divisions into the unified M RESET platform. ## Timeline ### 2026-08-24: Metlen achieves first waste combustion at Protos facility in the UK Metlen has reached a major milestone with the first waste combustion at its Protos Energy Recovery Facility in Cheshire, UK, marking its successful entry into the Waste-to-Energy sector. 2 sources. https://clstr.news/cluster/metlen-achieves-first-waste-combustion-at-protos-facility-in-the-uk ### 2026-08-21: METLEN achieves first fire on waste at Protos ERF plant in UK METLEN has achieved the ‘first fire on waste’ milestone at the Protos Energy Recovery Facility in Cheshire, UK, marking the final commissioning stages for the waste-to-energy plant. 5 sources. https://clstr.news/cluster/metlen-achieves-first-fire-on-waste-at-protos-erf-plant-in-uk --- Cite as: Metlen Protos energy recovery facility commissioning.
