Biogas Merse

Renewable biogas and biomethane, from the land, serving the territory:

A model of energy circularity that the Metano Toscana Group is rolling out on a large scale.
Clean energy for sustainable transport, sourced from agricultural biomass in the Merse Valley.

With Biogas Merse, Gruppo Metano Toscana brings a new circular energy model to life: agricultural biomass from the Merse valley is turned into renewable power for the region.

The plant converts local biomass into biogas, currently used to generate electricity. The next milestone is upgrading to biomethane—a renewable, fully certifiable energy source that can be seamlessly injected into existing grids, designed to supply the Group’s fueling stations and power sustainable mobility.

The distinguishing feature of the project is its closed-loop supply chain: energy originates in the fields, is processed locally, and returns to the community. Even agricultural vehicles will be able to run on the biomethane produced from the very biomass they help generate, reducing the use of fossil fuels.

A model in which agriculture, energy and the environment work together to create a more sustainable future.

A facility rooted in the local territory

Biogas Merse specializes in the production of renewable energy from agricultural biomass, contributing to the development of a sustainable energy supply chain that is fully integrated with the farming sector.

Today, the plant produces:

Approx. 1,000 kW/h
Over 24,000 kWh per day
Power supplied directly to the national grid

Our operations are built on the valorization of agricultural resources and a deep commitment to environmental stewardship.

From Biogas to Biomethane

Biogas Merse is entering a new phase of development: upgrading the facility for the production of biomethane from biomass.

The new configuration is projected to produce:

12,000 Smc /of biomethane per day

This evolution will enable:

A significant increase in energy capacity
Greater production process efficiency
The synergy between renewable energy and sustainable mobility
Continued contribution of energy to the national grid

A closed-loop production cycle

The project is built on a circular economy model designed to valorize every phase of the production process.

Agricultural biomass yields:

Renewable energy
Biomehtane
Digestate

Digestate, a natural byproduct of the process, is recovered and repurposed as a high-quality organic fertilizer for agricultural land. This effectively closes the loop, ensuring a tangible reduction in waste.

Clean energy and sustainable agriculture

The plant conversion delivers tangible environmental benefits:

Reduction in CO₂ emissions
Lower Nitrogen Oxide (NOx) emissions
Energy production from renewable agricultural sources
Enhancement of the local territory

Furthermore, digestate contributes to the regeneration of agricultural soils and supports certified
organic farms.
