Converting cheese waste into biomethane
At Wyke Summerset, the United Kingdom, the waste of cheese and milk production is digested and upgraded to green gas with a Carborex®MS system. The green gas (pure natural biomethane) is distributed to households in the remote rural area. The installation of DMT’s upgrading technology provides gas for 6000 to 8000 households every year, making heating and cooking in these houses more sustainable and possibly fossil free.
The area of Wyke Farms is very well known for its Cheese. The waste of the production of this famous cheese is digested to biogas and upgraded to green gas with a Carborex®MS system. The green gas, a renewable energy source, is distributed to households in the area of Aspatria. Additionally, the upgraded biogas can be further treated and used as vehicle fuel. This can be done through compressing it to CNG, Compressed Natural Gas or liquefying the upgraded biogas to LNG, Liquified Natural Gas.
By applying these technologies, Cheese producers can create a truly circular economy benefitting the environment and their business case. Cheese waste will help produce biogas. It includes whey and is process together with other agricultural waste products and helps develop sustainable farming practices.
Carbon footprint reduction
Biogas can be a very valuable by-product of decomposing animal waste in cheese production. The biogas is produced when the organic fraction of the waste of the cheese-making process decomposes anaerobically ( in the absence of oxygen). Biogas produced in an anaerobic digester typically contains 60 to 70 percent methane, the primary constituent of natural gas. The other 30 to 40 percent is carbon dioxide and is separated from the methane. Biogas recovery systems at agricultural sites, like at Wyke Farms, can be a cost-effective source of renewable energy that reduces greenhouse gas emissions.

Learn more about the project
This project does not only reduce waste but it also reduces the carbon footprint significantly it also produces energy that can be used on site and is injected into the national gas grid. The methane produced at Wyke Farms has the same quality as natural gas in the national gas grid displacing conventional fossil fuels.
