Our vision

We are committed to working with you as part of a virtuous, circular economy approach

“Evergaz is a company devoted to the production and uses of renewable gases. An independent company, created and run by entrepreneurs, Evergaz develops and manages long-term treatment solutions for organic waste generated by the Territories, recovered as renewable energy and natural fertiliser.

Drawing on local partnerships for each unit and our platform of shared skills is our challenge for ensuring the sustainable performance of our facilities. Our aim is to become a major Biomethane operator in Europe, which constitutes a key sector as part of the ecological transition”.

Philippe SPANNAGEL – CEO of Evergaz

Our values

Independence

Because every project is unique, we are agile and determined to provide the solution best suited to the local context, through technological independence and partnerships.

Entrepreneurship

We join forces with other entrepreneurs to encourage the emergence of local projects. Initiative and creativity are our company’s DNA to constantly adapt to the issues of the territories where we operate.

Commitment

It takes years to get a biogas facility off the ground, and the purchase prices of our green energy are guaranteed for 15 to 20 years. This is why we pursue a long-term strategy, committed to fighting for ecological transition over several generations.

Optimism

The renewable gas sector requires technical and regulatory adaptability over time and space. Evergaz stays the course over time and adapts to the dynamic of a high-growth market.

Our shareholders

Evergaz is an independent company majority-owned by Meridiam.

In the territories, we set up project companies with local stakeholders such as farmers, local authorities or local businesses willing to invest in biogas.
