KEON

KEON is an independent French group specializing in anaerobic digestion and biogas solutions, supporting the energy transition with innovative and sustainable biogas solutions. Founded by four engineers passionate about renewable energy, KEON brings together comprehensive services across the entire methanization value chain. Through its four subsidiaries - Ter'Green (co-development and co-financing since 2019), Naskeo (design and building since 2005), Sycomore (operations and maintenance since 2014), and Teikei (sourcing and transporting organic waste) - KEON is the only French group to combine all these services. With expertise spanning more than 20 years, KEON has delivered more than 90 methanization plants in France and internationally.

The group transforms organic waste into green energy and natural fertilizer through methanization, creating jobs and synergies between local stakeholders. KEON's plants convert biodigestates into biogas and digestat, contributing to greening gas injected into networks and reducing dependence on fossil fuels. The company currently operates across France and internationally, with Sycomore alone serving 200 methanization units and generating 6 million euros in revenue in 2024. KEON continues to drive innovation in responsible biomethane projects that benefit investors, farmers, municipalities, and individuals alike.
