Used Cooking Oil Pickup and Recycling in Chicago, IL
Mahoney Environmental has collected and recycled used cooking oil for foodservice operations since 1953, and Illinois is where the company started. Our professionals service restaurants, hotels, stadiums, airports, grocery stores, and institutional kitchens throughout the Chicago metro, including the Loop, the West Loop, Fulton Market, Hyde Park, Evanston, Naperville, and Schaumburg.
Mahoney controls each stage of the recycling process, including the equipment installed in your kitchen, the collection route, the processing plant, and the renewable fuel produced at the end. That control is what allows us to recover more value from your used cooking oil and return it through your pricing. Operations of every size, from a single storefront to a fifty-unit group, receive the same scheduled service.
Mahoney’s Chicago Area Facilities
Mahoney is based in the Chicago area. Our headquarters is in Woodridge, and our operations are on Mound Road in Joliet. Local facilities mean a shorter drive to your back door when a trap needs attention before lunch service, and technicians who work under the same regulations your inspector enforces.
The Challenge of Fats, Oils, and Grease Management in Chicago
Fats, oils, and grease (FOG) leave a commercial kitchen warm and liquid, then cool and harden inside the drain line. Fryer grease and food particles gradually narrow the pipe until a drain runs slow, an unpleasant odor develops near the dish area, or wastewater backs up through a floor sink during service. Chicago and Cook County both regulate grease disposal and grease trap maintenance, and a food service establishment that cannot produce a cleaning record may face fines or a temporary closure.
Mahoney Environmental serves a wide range of industries across the Chicago area:
Used Cooking Oil Collection and Recycling Services
Cooking oil has a limited working life, and once it is spent it should be transferred into a sealed container rather than held in open buckets. Our professionals pump the used cooking oil (UCO) from that container into the collection vehicle without your staff handling it, then deliver it to a Mahoney processing plant. Mahoney Environmental holds licensed EPA recycler status, and the volume collected from your kitchen is documented on a report available for audits and compliance filings.
Our Cooking Oil Collection Services Include:
- Routed pickups: Collection frequency set by your frying volume rather than a standard interval
- Tank level tracking: Monitoring that keeps your storage container from reaching capacity between visits
- Licensed hauling and processing: Transport from your back door to a Mahoney plant under full EPA licensing
- Equipment specification and installation: Handling and storage systems selected, installed, and serviced by our team
- Volume reporting: Documented gallons for audits, compliance filings, and sustainability reporting
Mahoney also delivers bulk fresh oil, so the same schedule that empties your used oil container fills your fryers. One vendor covers both ends of the cycle.
Benefits of Professional Cooking Oil Recycling
Working with a licensed recycler removes hot oil handling from your staff’s daily routine and eliminates the search for a drop-off site. Your back of house stays cleaner, injury risk goes down, and the oil collected from your fryers is refined into renewable diesel and sustainable aviation fuel (SAF) rather than sent to a landfill.
Commercial Grease Trap Cleaning and Installation Services
A grease trap sits between your kitchen and the municipal sewer system, and Chicago commercial kitchens are required to maintain one. Baffles inside the trap slow the flow of wastewater long enough for grease to rise, solids to settle, and only the water between those layers to reach the outlet pipe. Separation continues until the trap fills. After that point, grease travels toward the sewer line and flow through the plumbing system begins to restrict.
Consequences of Neglected Grease Traps
- Kitchen flooding and plumbing backups during service hours
- Odors near the dish area that carry into the dining room
- Sanitation citations at your next health inspection
- Emergency pump-outs billed at emergency rates
- Penalties from the city for an incomplete cleaning record
Our Grease Trap Cleaning Service Includes:
- Scheduled cleaning: Service intervals set by your frying volume and trap capacity
- Complete pump-out and repair: Full removal of accumulated FOG and solids, plus repairs to baffles, lids, and worn components
- Rodding and jetting: Clearing of drain lines and sewer lines that have already restricted
- Interceptor service: Maintenance for the larger underground units behind high-volume kitchens
- Condition reporting: A written report on every visit, creating a service history that identifies developing problems
- Emergency response: Around-the-clock coverage for overflows and unexpected backups
Commercial Used Cooking Oil Containers and Automated Systems
Transferring hot oil by hand from the fryer to a storage container is where most back-of-house burns and spills happen. Mahoney Environmental designs and installs handling systems that take that step away from your staff.
- Direct Connection Recycler System: Connects your fryers to indoor or outdoor storage. Staff transfer oil by turning a lever or flipping a switch.
- Indoor System: An indoor storage tank connected to your fryers, with a portable filter machine for UCO filtration.
- Heated Outdoor Bulk Container: Insulated and heated for Chicago winters, with anti-theft locks, a filter screen, and a level sensor. (Available in select markets.)
- Standard Storage Systems: Sealed bulk containers with screens over the opening, sized for manual deposit.
- Custom Equipment: Tanks, piping, and controls built around your kitchen layout.
Equipment Options: MES Inside 183, MES Inside 352, DC 48, DC 72. Caddies and shuttles are available for moving oil between the fryer bank and the storage tank.
Our outdoor equipment uses ported access rather than an open lid, so oil cannot be pulled out the way it can from a standard container. Mahoney also runs a theft prevention program built as a partnership between our customers, law enforcement, and our team. We help identify theft when it happens, educate local agencies on how UCO theft works, and pursue prosecution. Customers who help us catch it are eligible for rewards.
