One of the KEON Group’s flagship projects, this regional biomethane plant is equipped with several processing systems, which enable it to adapt to different feedstocks (manure, intermediate energy crops, animal by-products, etc.), producing 250 Nm³ CH₄/h. Working alongside regional farmers, TER’GREEN is designing and financing this plant, NASKEO is building it, SYCOMORE will operate it and TEIKEI will supply it with feedstock. It’s a prime example of all of KEON’s subsidiaries working in synergy!
