Transformation of solid waste into renewable gas in Ain
Plainénergie est le premier projet en Europe à combiner deux technologies innovantes pour transformer des déchets non valorisés en gaz renouvelable.

Backed by a consortium of public stakeholders from the French Départment of Ain, industrial companies, academics and a technological platform, Plainénergie aims to transform non-recovered waste into renewable gas for eventual injection into the existing network.
For the first time in Europe, this project combines "pyrogasification" and "biological methanation" technologies. The initial, now-completed phase was to quantify and characterise the region’s gasifiable waste. Laboratory tests are promising, with gas conversion rates above 97%.
The next step involves coupling a gasifier and a larger-scale methanation unit to carry out tests on the entire chain for converting waste into synthetic methane.

PLAINÉNERGIE: transforming our residual waste into renewable gas
The Community of Municipalities of the Plaine de l'Ain (CCPA), the PPP association of the Plaine de l’Ain Industrial Zone (SMPIPA), GRTgaz, French companies Séché Environnement and ENOSIS, INSALVADOR’s tech platform PROVADEMSE, and the DEEP and LISBP laboratories of the National Institute of Applied Science (INSA) in Lyon and Toulouse have just signed a collaboration agreement to develop the “PLAINÉNERGIE” project.
