Dairy cows are the ultimate upcyclers thanks to their four-chambered stomachs because they can eat things that would normally end up in landfills. In fact, U.S. dairy cows upcycle up to 306 million pounds of food waste every day. This may include dried distiller’s grain leftover from the ethanol industry, sweet corn cannery waste, and even unsellable chocolate! Dairy farmers work hand-in-hand with nutritionists to determine the ideal mix of byproducts, grains, vitamins, and minerals for their dairy cows to ensure they are being fed the best they can. By consuming inedible byproduct feedstuffs, dairy cows reduce the amount of food going to landfills, therefore reducing the greenhouse gases produced by landfills.
