Idea to reality: A Minnesota family company wanted to use recycled vegetable oil and glycerin from their small biodiesel plant to make green cleaning products. They needed help with glycerin purification and product formulation and testing.

AURI’s role: AURI scientists helped purify the crude glycerin and perfect the product recipes and manufacturing process for Klean Soap.

Outcome: Klean Soap now makes five all-natural cleaning products, which are being tested at the Minneapolis-St. Paul Airport. The company is also seeking green certification and setting up a distribution network.
