The two projects in Tartu and Vinni give the company an important foothold in the Baltic market for its EnviThan technology. Both gas upgrading units will be built as extensions to existing biogas facilities. During the roughly six-month construction project, customer AS EG Ehitus—a subsidiary of gas network operator AS Eesti Gaas—completed the necessary pipe laying work themselves. The raw gas components, including the purification and gas upgrading systems, were pre-fabricated as custom parts in Saerbeck. Rated at 465 Nm3/h, the gas upgrading plant in Vinni is scheduled to be operational this summer, and will run on biogas from wet and solid manure, flotates, and vegetable, harvest and food residues. Inputs for the 425 Nm3/h EnviThan plant in Tartu will include biogas from wet and solid manure, and harvest residues. Both plants will feed their biomethane into the existing natural gas network.
