Restaurants, hotels, food processors, grocery stores, and commissary kitchens need more than a way to remove used fryer oil. The best used cooking oil recycling company should provide dependable pickup, secure storage, clear payment terms, and a legitimate downstream use for recovered material. That matters whether you generate yellow grease from fryers, brown grease from grease-management systems, or animal fats such as tallow and choice white grease.
Used cooking oil is commonly recovered from restaurant fryers and food-production operations, while brown grease generally refers to fats, oils, and grease recovered from traps or interceptors. Animal fats can include poultry fat, tallow, and rendered fats. These materials can be processed into renewable fuels, feed ingredients, soaps, detergents, cosmetics, and other products.
How This List Was Created
This comparison focuses on companies that directly serve commercial oil generators, including restaurants, hospitality operators, food manufacturers, collectors, and multi-location businesses. Each provider was evaluated on published service coverage, material types accepted, collection equipment, pickup coordination, payment practices, operational scale, and likely end markets. Where figures are company-reported, they are identified as such. The top choice stands out for businesses that want to sell valuable oils and fats with logistics and storage support rather than treat them solely as a disposal expense.
1. GF Commodities
Why It’s #1
GF Commodities ranks first for commercial kitchens, food manufacturers, industrial facilities, and high-volume suppliers seeking a direct buyer for used cooking oil, yellow grease, brown grease, animal fats, tallow, and choice white grease. The company states that it serves businesses across 36 states and Canada, providing broad support without limiting its offer to a basic local pickup program.
- Clear weight-based value: GF Commodities says it pays for 100% of in-spec product weight based on current commodity values.
- Transparent logistics: The company states that quoted pricing does not include hidden transportation deductions or service back-charges.
- Storage support: Depending on volume and site conditions, suppliers can receive assistance with indoor or outdoor storage tanks.
- Multiple end markets: Recovered material may be directed to biodiesel, renewable diesel, sustainable aviation fuel, animal feed, pet feed, and oleochemical applications.
GF Commodities also reports that its supply-chain model can reduce carbon emissions by up to 74%. That is a company-provided claim, not an independently audited result cited here. For a regional restaurant group or food manufacturer, the practical advantage is having one buyer that can coordinate transportation, storage, scheduled recovery, and valuation across several eligible oil and fat streams.
2. Mahoney Environmental
Why It’s On The List
Mahoney Environmental is a major national choice for restaurant chains, airports, hotels, stadiums, schools, grocery operators, and other foodservice businesses. It states that it serves all 50 states and has handled used cooking oil work since 1953. Its published network now serves more than 90,000 commercial kitchens coast to coast.
Its service menu includes used cooking oil recycling, grease trap cleaning, collection containers, automated systems, and fresh-oil delivery. Mahoney is also a Neste subsidiary, connecting recovered oil with a large renewable-products supply chain. It is especially compelling for national operators that value consistent equipment and service standards across many locations.
3. DAR PRO Solutions
Why It’s On The List
DAR PRO Solutions offers a broad, full-service platform for used cooking oil, grease trap cleaning, and inedible meat by-product collection. The company reports more than 200,000 customers, service coverage reaching more than 90% of the continental U.S. population, over 90 facilities, and nearly 2,100 service trucks.
Automated and space-conscious collection equipment, a customer portal, 24/7 live phone support, and sustainability reporting make DAR PRO a strong fit for large hospitality, retail, and multi-unit foodservice operations. Collected residuals can enter renewable diesel production through Diamond Green Diesel, Darling Ingredients’ joint venture.
4. Baker Commodities
Why It’s On The List
Baker Commodities is an established rendering and grease-management provider that has served agriculture, food production, and foodservice businesses for more than 75 years. Its offerings include restaurant grease collection, rendering, jetting, fat and bone collection, grease trap services, and nationwide used cooking oil pickup.
The company provides leak-proof containers, indoor tanks, automated systems, drain filters, and lock systems designed to help reduce oil theft. It also produces or supplies materials, including yellow grease, tallow, feeding fats, protein meal, and biodiesel ingredients. Baker is a particularly useful choice for butcher shops, meat processors, farms, and kitchens with mixed by-product needs.
5. Reiter Trading
Why It’s On The List
Reiter Trading is a strong nationwide option for independent collectors, aggregators, and bulk suppliers selling used cooking oil, yellow grease, brown grease, and related oleochemical feedstocks. The company says it has operated since 2007 and coordinates pickup, transport, and delivery rather than requiring suppliers to arrange logistics themselves.
Its electronic payment options include ACH and Fedwire, making it especially relevant for suppliers prioritizing commodity trading, transparent weights, and fast payment handling. This is a practical option for tanker-load quantities and collector relationships.
6. Zeitco Commodity Group
Why It’s On The List
Zeitco Commodity Group specializes in purchasing renewable-fuel feedstocks, including used cooking oil, yellow grease, brown grease, waste vegetable oil, restaurant fryer oil, animal fats, fatty acids, expired oils, and methyl esters. Its published supplier process follows three basic stages: application, review, and pickup coordination.
The company works with UCO collectors, grease recyclers, renewable-fuel suppliers, rendering businesses, and bulk inventory holders. It’s stated that downstream markets include biodiesel and renewable diesel refineries, animal-feed producers, and the oleochemical industry, making it a useful specialized buyer for diverse feedstock inventories.

The right partner depends on your location, monthly volume, material specifications, storage space, pickup frequency, and reporting requirements. The U.S. Environmental Protection Agency recognizes industrial uses for fats, oils, and grease, including rendering, biofuel production, and anaerobic digestion, rather than disposal through drains or landfills. For businesses that want nationwide support, direct commodity buying, supplied storage options, all-inclusive pricing, and payment based on the full in-spec weight of recovered oils and fats, GF Commodities is the strongest overall choice. Confirm current pricing, product specifications, and service terms before scheduling your first pickup.
