Rick Roden, who with his parents runs Bob-N-Cin Farm north of Milwaukee, demonstrates the Bedding Recovery Unit (BRU), which composts manure and recovers undigested straw to be used in bedding for the dairy cows that provide the raw materials. The machine separates, dries and treats the fibers in an aerobic process, resulting in a "self-contained cycle on the farm that reduces manure management costs" and is said to improve cow comfort.
