Waga Energy was set up on January 28, 2015 in Meylan (Isère), an industrial area on the outskirts of Grenoble, by a group of engineers, three of whom previously worked for the Air Liquide Group: Mathieu Lefebvre, Nicolas Paget, and Guénaël Prince. Five years later, this young, innovative company has become an industrial SME with 40 employees and subsidiaries in the United States and Canada.

Resolutely committed to energy transition and tackling climate change, WAGA energy has already injected over 11 million cubic meters of biomethane into the gas grid, providing enough energy to run 10,000 cars for a year!

Waga Energy operates nine units, which currently supply 20,000 French households with clean, local, renewable gas produced from their waste, while also avoiding 30,000 tonnes of CO2 emissions per year.

These photos look back at some of the highlights of five years in which we’ve given it full gas!


Waga Energy won the circular economy category of the Future Investments Program (PIA) run by Ademe. The associated funding and an innovation loan from Bpifrance were used to complete development of the WAGABOX® technology and build the first unit. Two years later, Bruno Léchevin, President of Ademe (pictured above), said the following words at its official opening: “WAGABOX® is one of the jewels in the crown of the PIA program. It is a highly innovative project combining the three cornerstones of sustainable development – economy, ecology, and social cohesion. It is also a fine example of French gas engineering expertise”.


Waga Energy presented its technology at Pollutec, the environmental innovation event held every two years in Lyon. Waga Energy won the prize for tackling climate change awarded by Ademe and the French Ministry of Ecology, Sustainable Development, and Energy, and was one of three winners of La Vitrine de l’Innovation [Innovation Showcase] (with Lancey Storage and Fluidion, left and centre in the photo).


Activation of the first WAGABOX® unit at the Coved Environnement site (Paprec Group) in Saint-Florentin (Yonne) – this saw Waga Energy performing the first injection of biomethane sourced from a waste storage site into the European domestic gas grid.

Philippe Maillard, Deputy Managing Director of Suez, officially opened the WAGABOX® unit in Saint-Maximin (Oise). This was the first contract with the Suez Group, a major global waste processing operator. Others were to follow!

September 2017

The Wagateam moved from the Tarmac incubator (in Meylan) to a 280 m2 open space. Senior management took this opportunity to invest in a strategic asset essential to any self-respecting start-up – a table football table!

June 2018

Francis Dupouey, President of Trigone, officially opened the third WAGABOX® unit at the Pavie storage site (Gers). This made Trigone the first French local authority to recover biogas from its facility as biomethane injected into the grid. It was joined by the Lorient Urban Community (Morbihan) and the Multi-Purpose Intercommunal Syndicate (SIVOM) for Saint-Gaudens, Montréjeau, Aspet, and Magnoac (Haute-Garonne).

December 2018

The WAGABOX® unit in Saint-Palais (Loiret) was officially opened by Bernard Harambillet, Managing Director for Recycling and Recovery at Veolia France, Karine Vernier, Director of the Energy and Circular Economy Program, Arnaud Leroy, Chairman of the Board of Ademe, and Aymar de Germay (President of SDE38). This was Waga Energy’s first contract with Veolia, a global leader in optimized resource management.

December 2018

The Solar Impulse Foundation set up by solar aviation pioneer, Bertrand Piccard awarded the WAGABOX® technology the Efficient Solution label. This label created for COP 23 identifies 1,000 solutions that help protect the environment cost-effectively at global level. Waga Energy was one of the first companies to receive it!

October 2019

Waga Energy took part in the South Summit start-up competition, an innovation event held in Madrid, Spain. It won the Energy & Sustainable Development category.

November 2019

Waga Energy raised €10 million to boost its growth in Europe and North America. This included investments from the three shareholders that have contributed to the venture’s success from the outset: ALIAD (Air Liquide Venture Capital), Ovive and Starquest Capital. They were joined by two new investors – the funds Noria and Tertium Invest (left to right in the picture: Nicolas Paget and Mathieu Lefebvre, co-founders, Stéphane Assuied and Pierre Grand-Dufay, Tertium directors).

We would like to say a big thank you to everyone who has contributed to Waga Energy’s success
and the fight against climate change
