Sometimes, the results of USDA science show up in the most unlikely places—maybe even in your cat’s litter box.

USDA Agricultural Research Service (ARS) scientists have discovered a way to make kitty litter that’s nearly 100 percent biodegradable by processing spent grains left over from corn ethanol production.

And what’s good for you and your cat may also be good for the environment. ARS researcher Steven F. Vaughn and his colleagues have shown that litter made with these grains as the starting material may prove to be more environmentally friendly than popular but nonbiodegradable, clay-based litters that mostly end up in landfills.

Twenty years have passed since the U.S. Postal Service first started transitioning from lickable stamps to the peel-and-stick squares used today, thanks to the research by the U.S. Forest Service’s Forest Products Laboratory in Madison, Wis.

The two agencies first research collaboration focused on developing the peel-and-stick – or pressure-sensitive adhesives – that didn’t gum up the equipment used to recycle paper. By using this adhesive an additional 20 million tons of waste paper can be recycled annually. Read more »
