biodigestoreCIPNES is currently implementing an extensive program of strategic actions with little environmental impact, aimed at increasing energy efficiency and reducing supply costs in order to support production activities, and is awaiting authorisation for an "anaerobic digestion" production plant for biomethane, produced by the treatment of organic and special non-hazardous differentiated urban waste, currently treated in the consortium composting structure.

This biogas derives from anaerobic digestion of biomass deriving mainly from solid urban waste,  and will be treated to achieve the biomethane and thus be introduced into the urban natural gas network for local distribution in the Olbia industrial consortium, as well as serving the new health and research centre, Mater Olbia.

The new anaerobic biodigester will be able to treat 25,000 tons of urban organic waste every year and other biomass for an additional 45,000 tons, and produce about 500 standard cubic meters per hour of biomethane from the urban waste alone, also to be used for heat generation.

The realization of this plant design has strategic importance in terms of recovery, reuse and valorisation of waste and urban and treated vegetable waste to produce clean energy and, thanks to the incentives recognized by the Energy Services Operator (GSE), will have a positive economic impact that will significantly reduce the pricing of the consortium treatment service of the RSU in the urban area of ​​Olbia.
