A garage inventor has built a "tornado in a can" that is an amazing way of drying and pulverizing just-about anything.
Each year, the U.S. poultry industry generates about 4 million tons of blood, feathers, heads, feet and entrails, including some 300,000 tons on the Delmarva Peninsula. An additional 50,000 tons of dissolved solids such as fat are skimmed from the wastewater stream, much of it sprayed on farm fields as fertilizer. And much of the 300 million tons of shells produced by laying hens each year is worked into the soil…
Running that material through a drier and then through Polifka's machine could produce a powder form of those poultry byproducts that could be sold as a flavoring or nutritious additive to pet foods or fertilizers, Winsness thought.
"The single most important quality of the tornado in a can is whatever goes into it comes out with its nutritional value," he said. "You can get four times the price of nonedible waste."
(Thanks, Henry!)
