Onkens 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 companys 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 Onkens trailers and filter bins to more efficiently collect oil filters for recycling. Over the next 30+ years, the recycling industry has grown and changed, and Onkens has been there every step of the way, creating new products and adapting existing products to the diversified needs of the industries it serves. We have improved our grease trailers and grease containers over the years, and have added grease caddies, inside grease storage tanks, new and used motor oil storage containers, including double wall tanks, and several other items to our product line.
