What Evergaz does

Evergaz is a French-headquartered integrated operator of methanization (anaerobic digestion) sites, founded in 2008 and headquartered in Courbevoie, France. The company develops, finances, supplies, operates, and maintains anaerobic digestion facilities that convert agricultural effluents, agro-industrial byproducts, and other organic waste into renewable energy and organic fertilizer. Its current portfolio comprises 22 methanization sites across three European countries — France, Germany, and Belgium — with a combined annual production capacity of approximately 1,000 GWh eq. CH4 and the ability to process 600,000 tonnes of organic matter per year. Two additional units are under construction and five cogeneration-to-injection conversion projects are in the pipeline, targeting 1,100 GWh PCS biomethane and 1.1 million tonnes of annual inputs by 2027.

The company's service offering spans four interconnected activities: project development (including co-construction with local stakeholders and structuring of citizen shareholder collectives), organic matter supply (sourcing and logistics for agricultural and agro-industrial substrates), operation and maintenance (daily plant management, biological and economic optimization, preventive and corrective maintenance), and multi-energy valorization (biomethane grid injection, cogeneration of electricity and heat, BioGNV for mobility, bio-CO2 for industry, and digestate as fertilizer). Evergaz serves five primary stakeholder segments — local collectivities, farmers, industrial and agro-industrial companies, transporters, and citizen shareholder collectives — through long-term contractual frameworks including CPB (Certificats de Production de Biogaz), PPA/BPA (Power/Biogas Purchase Agreements), and multi-year territorial co-ownership arrangements.

Revenue is generated from three main streams: sale of produced energy under long-term offtake contracts (biomethane injected into networks, electricity, heat), fees for processing organic waste, and sales of digestate as organic fertilizer, with project development and site-recovery services as additional managed-service revenue. Following a €60 million capital increase in December 2024, Meridiam became the majority shareholder alongside SWEN Capital Partners and historical shareholders, reinforcing the company's long-term industrial positioning as a European integrated biogas platform.

Revenue model

1. Methanization Site Operations: Evergaz develops, operates, and maintains methanization sites that convert organic waste into renewable energy. Revenue comes from selling the energy produced (biomethane injected into networks, electricity from cogeneration, heat) under long-term contracts (CPB, PPA/BPA). The company also generates revenue from processing fees for organic waste treatment and from selling digestate as fertilizer.
2. Project Development and Reprise Services: Development of new methanization units for territorial projects, including project structuring, financing, and shareholder collective organization. Also includes takeover and optimization of existing sites.
3. Industrial Organic Waste Processing: Processing industrial organic waste, co-products, and byproducts from agro-industrial companies, providing long-term biogas supply contracts (BPA - Biogaz Purchase Agreements) and waste treatment solutions.
