Germany-headed biogas producer and technology provider EnviTec Biogas AG has announced that it has signed its first contract for the construction of a biogas upgrading plant with carbon dioxide liquefaction in Belgium.
The contract is with Byont, a leading Dutch energy provider based in Hengelo, that develops, operates, and invests in biogas projects across the Benelux region and Germany.
The company focuses on converting organic residues into renewable gases such as biomethane aka renewable natural gas (RNG), and liquefied biomethane (bioLNG), thereby actively contributing to a decarbonized energy future.
The plant will be connected to an existing biogas facility and, upon its scheduled completion in July 2026, will inject 735 Nm³/h of biomethane into the Belgian gas grid, said Maurice Markerink, Managing Director of EnviTec Plant Construction.
Furthermore, 24 tonnes of liquefied biogenic carbon dioxide (bioLCO2) will be produced on-site per day.
This enables us to actively contribute to promoting the supply of green energy and the circular economy of CO2, said Roel Slotman, CEO of Byont.
In addition to implementing the planned EnviThan gas upgrading system with carbon dioxide (CO2) liquefaction, the German biogas plant manufacturer will also be responsible for the conversion of the existing biogas facility.
This ensures that the entire plant will comply with the latest standards, Maurice Markerink explained.
Two more biogas plants operated by Byont are in the planning and approval phase.
We also intend to convert these two Dutch plants to biomethane production, combined with CO2 liquefaction technology, utilizing EnviTec Biogas’s engineering expertise, revealed Roel Slotman.
