Japanese environmental systems operator Kanadevia is set to construct a new wet anaerobic digestion (Wet AD) biogas plant in Castelvetrano, Sicily. The project, developed under Italy's DM2022 biogas decree framework, will utilize Kanadevia Inova's proprietary technology to convert over 63,000 tonnes annually of organic waste, including municipal solid waste and food waste, into grid-quality biomethane.
Kanadevia Inova will hold a 90% ownership and controlling interest in the local project company, Sicily Biomethan S.r.l., and will be responsible for the plant's engineering, procurement, and construction under a turnkey EPC contract. The plant is designed to have a biogas production capacity of approximately 4,420,000 Sm³/y and will feature a membrane-based upgrading system. It is projected to produce around 45.1 GWh of biomethane annually, contributing to sustainable energy supply and the circular economy in the region.
Kanadevia Inova has also been involved with the Pianfei biogas plant, which reached commercial operation in September 2025. This plant benefits from a 15-year feed-in-premium tariff and received Capex Grant recognition from the GSE, the Italian agency for energy efficiency and renewables. Kanadevia Inova designed, built, and operates the Pianfei plant under a Build, Own, and Operate (BOO) model, utilizing its own biogas upgrading technology.
