A new biogas plant in Germany has been commissioned and has been supplying to the public grid since May.
The Weltec Biopwer facility, based in the industrial region of Altmark, took eight months to construct and consists of four digesters, six digestate storage units and a liquid reservoir. It produces 1,650m3 of raw biogas an hour, 250m3 exclusively for the heating needs of the plant itself.
The rest of the biogas is converted, via chemical amine treatment, into 700m3 of processed biomethane an hour. This amount can supply 5,000 homes with heat and power. It uses feedstocks including maize silage, dry chicken dung and sugar beets.
‘This refinery demonstrates that we must provide the right answer to the growing demand for biomethane for the various utilisation paths,’ Jens Albartus, director of Weltec Biopower, was quoted as saying.
