Atlante Gestion participated last July in the financing of two territorial methanization projects in France whose development is ensured by the CVE Group, for an amount of 3 058 000.

Two projects of territorial methanization under construction

The key player in the biogas and renewable energy sector – CVE – has partnered with Atlante Gestion to finance the construction of two projects, which consist in the installation of two territorial methanization units: Equimeth – developed in partnership with Ile-de-France Energies – and De Breuilh. These projects are currently under construction and have obtained all their administrative authorizations, i.e. a building permit, a connection offer and a secure gas purchase tariff. They have also already get bank financing.

Located respectively in the Dordogne and Seine et Marne departments, the De Breuilh and Equimeth methanization units are designed to treat and recycle organic matter in the region. They will produce biomethane, which by 2022 will be injected locally into the natural gas distribution network, as well as an organo-mineral fertilizer, which will also be recovered locally via Regener (the CVE service offering dedicated to agronomic solutions).

Contributing to financing the Ernergy Transition

The investment follows the public objectives of improving the energy performance of the territories by financing projects that reduce energy consumption and contribute to the Energy Transition.


More than 40,000 metric tons of organic matter will be processed each year by the two facilities, which will produce around 40,000,000 kWH of biomethane per year*. This is equivalent to the annual gas consumtion of nearly 3,440 french households**. Thanks to the installations, 10,000 tons of CO2 will be avoided per year.

How does methanization work ?

Methanization is a phenomenon that produces biogas energy, through the decomposition and fermentation of organic matter. This natural process is due to the action of micro-organisms that digest organic matter. The digestion occurs naturally in certain environments, for example in marshes.


It can also be reproduced by human action, by heating and stirring the organic matter in hermetic enclosures called digesters with total absence of contact with oxygen. The process must be controlled at all times in terms of temperature and pressure, and lasts from 20 to 40 days. Methanization is used for energy production and sale, and also provides a natural and organic amendment for agriculture: the digestate.

The biogas produced by methanation is a 100% renewable energy, which contains between 40 and 60% methane (CH4) for almost as much carbon dioxide (CO2).

The project developer – CVE, a committed producer and supplier of renewable energies

CVE is an independent producer of multi-energy and multi-country renewable energies, active in the solar photovoltaic, biogas and hydroelectricity markets. 50% of its business is conducted in France from the headquarters in Marseille, but the group also realizes operations in Chile and in the United States and is expanding in Africa.

CVE defends a market vision based on decentralized energy production and a direct energy sales model. The group’s objective is to respond to the energy and environmental needs of companies and communities through the services provision.

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.
