A Soybean Hull-based Cat Litter Performs Better Than Some Commercial Products, but Peoria Ag Lab is Having Difficulty Finding a Producer

Scientists at the Peoria Ag Lab have improved upon their recipe for a better kitty litter. Now they just need to find a company interested in bringing it up to a commercial scale.

Plant physiologist Steve Vaughn says soybean hulls may be the key ingredient for a better cat litter.

Previously, Vaughn's team tried out litters based on dried distillers' grains and Eastern red cedar flakes. But two years ago, they received a grant to find a use for soy waste products.

"And we come up with a formulation that is actually as good in every respect are better in some factors than anything that's on the market," he said.

The soybean hulls are combined with guar gum and mineral oil to create the right mix for an effective kitty litter.

Test results published this year show the soybean hull-based litter works as well or better than four of the leading commercial litters in reducing dust and odors. But Vaughn says it's been hard to sell companies on their idea, so far.

Video: Independent Seed, National Impact | On The Brink: Episode 9

A survey of 200 independent seed businesses reveals what Canada's seed sector actually contributes — and what it stands to lose.

On the Brink, Justin Funk, a third-generation agri-marketer, shares the findings of a national survey conducted in early 2026. The numbers reframe the conversation: independent seed companies in Canada represent upwards of $1.7 billion in dedicated seed infrastructure, approximately 3,000 full-time equivalent jobs in rural communities, and an estimated $20 million in annual community contributions. And roughly 90% of Canada's cereals, pulses, and other small pollinated crops flow through them.

The survey also asked how dependent these businesses are on public plant breeding to survive. The answer was unambiguous. For policymakers evaluating the future of publicly funded breeding programs, Funk argues the economic case for this sector and the case for public plant breeding are the same argument.

On the Brink is a cross-country video series exploring the future of plant breeding in Canada. Each episode features voices from across the industry in an open, ongoing conversation about innovation and long-term investment in Canadian agriculture.
