Waga Energy and Veolia signed a contract in early October in Paris to install a Wagabox purification unit at the Claye-Souilly (Seine-et-Marne) waste storage centre.

Commissioned in February 2022, it will produce biomethane from waste and supply renewable gas to 20,000 homes in the Paris region. Wagabox is a breakthrough technology for the recovery of biogas from landfilled waste. It separates the methane from the other components of the biogas produced by the decomposition of organic matter, to produce biomethane. This biogas is complex to purify because it contains air. In addition, its flow rate and composition vary with weather conditions.
The biomethane produced by the Wagabox unit in Claye-Souilly will be injected directly into the natural gas distribution network, to supply individuals and businesses in the Paris basin. This will prevent the emission of 25,000 tonnes of CO2 per year into the atmosphere (by replacing natural gas, which is a fossil fuel). The Claye-Souilly storage center will thus actively participate in the ecological transition.
The construction of the unit and its connection to the natural gas network represent an investment of 10 million euros which will be supported by Waga Energy. The Veolia group will make the necessary arrangements to accommodate the equipment on its site for an amount of 1 million euros.
The Claye-Souilly project is the third green gas injection project undertaken by Waga Energy and Veolia: a first Wagabox unit has been in service since November 2018 at the Saint-Palais (Cher) waste storage centre and a the second is currently under construction in Le Ham (Manche). In total, ten Wagabox units are in operation in France. Offering a total capacity of 200 GWh / year, they supply 32,000 homes with renewable gas and prevent the emission of 40,000 tonnes of CO2 per year into the atmosphere.
Since 2006, the Veolia facility in Claye-Souilly has been recovering biogas from waste in the form of electricity and heat, using engines and turbines. In 2009, Veolia also developed the first biomethane fuel production unit from waste biogas (Meth'OD). The Wagabox unit will replace part of this equipment and purify 3,000 m3 / h of biogas, with superior energy and environmental efficiency.
“Bringing net CO2 emissions to zero by 2050, as the European framework sets out the ambition, requires the implementation of large-scale industrial solutions” said Hélène Lebedeff, Territory Storage & Recovery Director of Veolia, Recycling and Waste Recovery activity, in Ile-de-France. “The recovery of biogas from landfilled ultimate waste is one of the key levers in our activities to contribute to this objective. This major project with Waga Energy is an emblematic illustration of this in terms of its size and impact. A true example of industrial and regional ecology, it will make it possible to produce local, renewable and carbon-free energy ”.
