With about 1500 biogas production plants, Italy is now the third largest producer in the world with a installed capacity of 1.400 MW

Biomethane is a renewable energy source derived from agricultural biomass (dedicated crops, by-products and agricultural waste and animal waste), agro-industrial (waste from the food processing chain) and the Organic Fraction Municipal Solid Waste (OFMSW). Biomethane is obtained in two phases: raw biogas production - predominantly through anaerobic digestion of biomass - and subsequent removal of non-compatible components (CO2), a process also known as "upgrading".

Biomethane, a renewable and programmable source of energy, can answer to emission reduction goals by exploiting existing gas networks and contributing to increasing domestic methane production. This perspective would also have a positive impact on the agri-food sector by promoting an economic model based on sustainability and resource-friendliness.

The contribution of biomethane to the decarbonisation objectives is not limited to the energy consumption phase only. Its production process can help to significantly reduce emissions in the farming sector (14% of climate changing gases) and restore organic matter to the soil. In fact, the digested material (what remains after the anaerobic digestion of the agricultural matrices) is an excellent natural fertilizer. Farms could therefore substantially reduce their production costs and increase their competitiveness. In addition, biomethane produced with sustainability criteria can increase the ability to absorb and preserve soil carbon.



It is

  • Renewable: it is generated from agricultural biomass
  • Sustainable: CO2 neutral and could significantly reduce agricultural sector emissions (7% GHC emissions in Italy)

Its use is:

  • flexible: suitable for all energetic needs (also as a fuel for transportation)
  • programmable: assimilable to natural gas, it may use already in place transportation and storage facilities
  • efficient: suitable in the distribution

Support to national biomethane valuechain

Snam, together with the Consorzio Italiano Biogas and Confagricoltura, has developed and presented a manifesto to the public in support of the Italian biomethane supply chain.

The document, directed at the government and the European Commission and circulated on the occasion of the 2016 edition of Biogas Italy, an event in the sector sponsored by the Ministry of the Environment and the Protection of Land and Sea, highlights the strategic role of biomethane in the energy transition to an economy based on sustainability and the circular use of resources.

The first Snam workshop entirely dedicated to biomethane was held in December 2016 at San Donato Milanese. The event, which was attended by around one hundred people, representing over 50 gas transport system operators and associations, helped to take stock of the situation in view of the injection of the first flows of biomethane into the Snam network expected at the start of 2017.

For more information on Snam's contribution to sustainable development, consult a dedicated document or Sustainability Report 2016.

Biomethane starts to flow

A new renewable, clean and efficient energy source now flows through Snam’s pipelines. On Friday 30 June, the first biomethane has been injected in the national pipeline network by Montello SpA, an Italian and European leader in bio-waste recovery and recycle.
