About Us
Mahoney Improves Your Bottom Line and the Environment
Since 1953, Mahoney Environmental has helped foodservice operators turn used cooking oil (UCO) into a recoverable resource instead of a disposal problem. We run the full recycling process, from equipment setup to collection to processing to finished product, so more value comes back to your kitchen. Oil leaves your fryers as a problem and returns to the world as renewable fuel.
That focus has made Mahoney one of the most established cooking oil recycling companies in the country. We serve more than 90,000 food service establishments through a coast-to-coast network, and we have done one job since 1953: take the oil off your hands and turn it into something useful.
What We Recycle
Mahoney handles the back-of-house oil that any commercial kitchen produces every day. Our work centers on cooking oil and grease, not the automotive or industrial side of oil recycling. That includes used cooking oil collection and recycling, grease trap cleaning that keeps fats, oil, and grease (FOG) out of your pipes, grease theft prevention, fresh oil delivery, and the collection containers and equipment that hold it all.
Used cooking oil is a valuable resource, not garbage, and we never treat it like hazardous waste. Most of it is vegetable oil, and every gallon we collect becomes raw material for renewable fuel. Treating it that way keeps oil waste out of your drains and out of landfills, and it gives restaurants, food trucks, and institutional kitchens a cleaner way to handle proper disposal.
How Our Used Cooking Oil Recycling Process Works
Cooking oil recycling only works if the oil is collected, cleaned, and tracked the right way. Here is what happens after we pick up your oil:
- We handle cooking oil collection from your location on a set schedule, using trained drivers and the right equipment.
- At our processing facility, incoming oil is screened for contaminants and heated to separate water and fine particles.
- Heated settling tanks and a centrifuge separate clean oil from solids and water.
- Finished oil, often sold as yellow grease, is tested for quality and tracked for full traceability across everything we sell.
- Nearly 100% of the UCO we collect is sold as feedstock for renewable fuel, including sustainable aviation fuel (SAF) and renewable diesel.
This closed-loop recycling process turns a waste product into something useful and cuts the greenhouse gas emissions tied to fossil fuel. Improper disposal sends oil down the drain or into a landfill. Recycling sends it back out as renewable diesel.
What Makes Mahoney Different From Other Cooking Oil Recycling Companies
Plenty of cooking oil recycling companies will haul oil away. Fewer control the whole chain the way Mahoney does.
- One provider, start to finish. We own every step, from collection to processing to finished product. Fewer handoffs mean more reliable service and more value back to you.
- 70+ years and 90,000+ customers. We’ve managed cooking oil collection for commercial kitchens since 1953, with a coast-to-coast network that still feels like a local business when you call.
- Compliance built in. We help your kitchen stay on the right side of environmental regulations, with documentation that meets and exceeds Environmental Protection Agency standards.
- Verified sustainability. We participate in the ISCC EU and CORSIA certification programs, which confirm the oil we collect as genuine residue for renewable fuel.
- Part of Neste. As a Neste company, the used cooking oil we collect feeds one of the world’s leading producers of renewable diesel and sustainable aviation fuel.
Whatever your kitchen’s specific needs, our recycling service is built to be a hassle-free part of your week, with a real positive impact on both your costs and your carbon footprint.
