Wensleydale Cheese Producing Biogas
More and more businesses are coming to realise the benefits of going green. One that’s recently taken the plunge is Wensleydale Creamery in Yorkshire.
The company is best known for its Wensleydale cheese, and now it’s also helping to power local homes using a by-product of the cheese production process.
Leftover whey will now be sent to an anaerobic digestion plant in North Yorkshire, that’s run by Iona Capital, to produce 10,000 MWh of energy per year. This will be turned into thermal power that’s used to heat 800 homes in the region.
David Hartley, managing director of Wensleydale Creamery, commented: “The whole process of converting local milk to premium cheese and then deriving environmental and economic benefit from the natural by-products is an essential part of our business plan as a proud rural business.”
Co-founder of Iona Mike Dunn added that what’s left of the whey after it’s been converted into green gas will be fed onto neighbouring farmland to improve the quality of the topsoil.
“This shows the real impact of the circular economy and the part intelligent investment can play in reducing our CO2 emissions,” Mr Dunn added.
And it’s not only farm waste that can be used for anaerobic digestion. Sewage and sludge from wastewater can be a valuable source of biogas, according to one expert.
Speaking to Environment Journal Online recently Tim Broadhurst, CCO of CooperOstlund, explained that sewage and sludge can produce ten times the energy it takes to treat it.
If you’re considering commissioning your own anaerobic digestion plant for your farm or business, make sure you invest in high-quality vacuum relief valves.
