We learned that for every pound of cheese produced, approximately nine pounds of whey is made as a byproduct. Dairy producing plants are left with vast amounts of whey and factory produced wastewater and the problem of how to dispose of it. Many turn to agricultural repurposing (fertilizer), but in order to come up with a circular solution, the plant can power its own facility through whey-to-biogas conversion. When mixed with microorganisms, whey can undergo fermentation, where the process of anaerobic digestion results in biogas products from methane and carbon dioxide. These gases can then be used to generate hot water and electricity. Cheese fuel!
