Biomethane

Zero-mile Biomethane

The production of a resource such as biomethane brings both economic and environmental benefits. Italy is heavily dependent on foreign countries for the supply of methane: according to data from the Ministry of Economic Development in 2018, Italy produced 5,448 million Sm3 (standard cubic metres) of methane, while it imported 67,872 million, 92.6% of the total. The production of biomethane from organic matrices would instead be entirely national, activating a zero-mile supply chain.
According to the most recent ISPRA Report, the Metropolitan City of Milan produces approximately 215,000 tons of damp waste per year and currently has an anaerobic treatment plant capacity of 90,000 tons. Thanks to our plants, an additional 107,000 tons of damp waste could be treated annually, without the need to build new facilities or new production plants.
In particular, the amount of biomethane produced by our plants in Pero, Bresso, Robecco sul Naviglio, Sesto San Giovanni, Peschiera Borromeo, Cassano d 'Adda, Trucazzano, would be able to supply about 39,000 cars, 2.5 times the number of methane-powered cars on the road in the Metropolitan City of Milan.
In March 2018, for the first time at national level the Division Office formally approved the investment plan of the Integrated Water Service including a plant aimed at the production of biomethane from the anaerobic digestion of treatment sludge.
More specifically, this is the Bresso/Niguarda treatment plant we operate. CAP Group's 7 digesters are potentially able to produce 11,383,194 Sm3 per year of biomethane, covering about 20% of future demand.
