KEON

The founders of the KEON group have always been sure about the benefits of biomethane production and the crucial role it will play in the future. They also strongly believe that global efforts are needed for the success of such a project. That’s why employees seeking greater involvement in this innovative business venture can support its development by purchasing shares in the company.

Thanks to this virtuous business model, almost 50% of KEON’s employees and founders are now company shareholders. We would like to extend our thanks to each one of them.
