A biogas plant located in Szarvas, Hungary, was initially designed to process regional waste. Following acquisition by the MOL Group and subsequent technical upgrades, the facility now also produces green biomethane. This biomethane is currently being supplied directly into the local gas network in Szarvas. The plant effectively utilizes waste material from the surrounding area, converting it into a renewable energy source. This represents a significant step toward sustainable energy practices in the region. The upgraded facility demonstrates a commitment to waste reduction and resource recovery. The success of the Szarvas plant showcases the potential of biogas technology for greener energy solutions.
