SCARA: a century-old agricultural cooperative. Its core business focus is the collection and marketing of grain, including wheat, barley, rapeseed and sunflower.

Committed to environmentally friendly processes, it offers a range of innovative and effective services to support sustainable agriculture.


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.
