Our company is pleased to announe its participation of €2,3M in the financing of a territorial methanization project in France, whose development is ensured by the CVE group.

A territorial methanization project under construction

After partnering with CVE and contributing last July to the financing of the two methanization units Equimeth and De Breuilh, Atlante Gestion has allowed the financing of the construction and commissioning of the Montbrison power plant (42), located in Auvergne-Rhône-Alpes. This project was developped by CVE in partnership with Sem’Soleil and with the support of the local authorities : Loire Forez agglomeration and the City of Montbrison.

This project has been under construction since January 2021 and has obtained all the administrative authorizations. i.e. a building permit, an administrative authorization to operate a connection offer and secure gas purchase tariff. It has also already obtained bank financing as well as financial support from the European Regional Development Funds for the Auvergne-Rhône-Alpes Region, the Auvergne-Rhône-Alpes ADEME and the Loire-Bretagne Water Agency for a total of €1.075.000.

Contributing to the financing of the Energy Transition

The objective of this unit is to treat and valorize the organic materials of the territory. It will produce biomethane, which will be injected locally into the natural gas distribution network by the end of the summer of 2022, as well as an organo-mineral fertilizer, which will also be recovered locally.

Up to 25,000 tons of organic material will be treated each year the facility, most of which will come from a supply radius of less than 40 km. This is equivalent to the annual gas consumption of nearly 3,800 French households.



€61 million

Sociale Infrastructure

Sarthe region

Lead investor in the construction and rehabilitation of four middle schools in the Sarthe region, located in Arnage, Coulaines, Le Mans and Noyen-sur-Sarthe to receive 2,300 students.

The project is in the operation phase since 2019.


The project was subject to carbon assessment. Seeing the results, in end-January 2018, CERTIVA awarded MAINE COLLEGES 72 permanent HQE (high environmental quality) certifications for the “Programme Design” phase for each of the schools. The permanent HQE certification for the “Development” phase was awarded in November 2019 for all the schools.

As of November 2019, MAINE COLLEGES has also been awarded the Effinergie + label. This label testifies to the improvement in the buildings’ energy efficiency in relation to the 2012 Réglementation Thermique (the 2012 Heat Regulation).

Water management

Wastewater is let into the wastewater sewerage systems of the towns concerned.

A rainwater harvesting system is planned for sanitary use, so as to cover 10% of the water requirements for toilet bowls and urinals in the toilet facilities.

Waste management

Implementation of waste segregation.

All materials used in the construction have zero or very low VOC (Volatile Organic Compounds) levels.

Energy efficiency

The schools were equipped with low temperature radiators that require 30% less energy to provide the same thermal comfort given their much larger contact surface with the ambient air.

Ceiling radiant panels that allow a more accurate monitoring of power consumption, have been installed in the canteens.

PV solar panels will be installed horizontally on the roof, covering a total area of 57.12 m2.

The kitchen appliances run on electricity and are equipped with an energy optimiser.


The project complies with contractual commitments in terms of first-time employment, namely 20,000 work hours, and in employing SMBs for which the recruiting rate is 40%.

Asbestos removal and demolition works are carried out during school vacations and the floors are hosed in case of heavy dust.
