Redefining Leak Proof Storage.

See what makes us different.

​Onken’s Incorporated serves many industries in the areas of grease storage and recycling and oil storage and recycling. These include rendering, biofuel, biodiesel, used oil recyclers, antifreeze recyclers, industries needing lubricant bulk storage, and many others.

Our company’s founder, Don Onken, created the first-of-its-kind bulk grease collection bins and bulk grease collection trailers. This system dramatically increased efficiencies in the storage, collection, and recycling of used cooking oil. Next came the modification of this system to modernize oil filter recycling and collection. This “bulk” system uses Onken’s trailers and filter bins to more efficiently collect oil filters for recycling.
