DAR PRO Solutions offers used cooking oil collection and grease trap services to restaurants, supermarkets and others in the hospitality industry. These FAQs focus on used cooking oil in a general sense - how is it used, how to dispose of it safely, and do we recycle your Thanksgiving turkey grease (sorry, but no).  For more information on our UCO services and how we collect used cooking oil from our customers, see our Restaurant FAQs.

How much used cooking oil is generated in a year?

According to the National Renderers Association, approximately 4.4 billion pounds of used cooking oil is collected annually from restaurants, grocers, hotels and casinos, and other foodservice providers in the US and Canada.

How do I dispose of used cooking oil?

Whether you are a homeowner or a business owner, used cooking oil should never be disposed of down the drain, as it can clog pipes causing problems that can be costly to fix. Overflows from clogged pipes can also result in fines for business owners who incorrectly dispose of their grease. Businesses should contact a reputable service provider to provide collection bins or tanks and who will pick up your used oil on a regular basis.

What happens to my used cooking oil after it’s picked up from my store?

After our service tech has removed the used cooking oil from your store, we take it to one of our processing facilities located coast-to-coast. There it is put through strainers to remove contaminants (grill bits and debris), heated to remove water and kill off any pathogens, and marketed as yellow grease, a commodity whose value is tracked and published daily. Most of the yellow grease is used as a nutritional animal feed or pet food ingredient, or used to produce biofuel. Our biofuel production process (we own and operate 3 biofuel facilities) also yields valuable co-products – glycerine, methyl-esters, naphtha, renewable propane – that are used in a wide array of consumer and industrial products.

How do homeowners dispose of their kitchen grease?

NEVER pour used grease down your kitchen drain unless you like to personally support the local plumbers. If the used grease is strained and stored in a cool place, it can safely be reused a few times. Once the oil is spent, contact your city; many offer used cooking oil drop-off points, particularly during the Thanksgiving and Christmas holidays. If no drop-off is available, put the used oil in a disposable container and discard in your trash.

Can I put used cooking oil in my compost pile?

Avoid adding used cooking oil to your compost pile; small amounts may not be problematic, but too much can emit an unpleasant odor attracting rodents and animals and can encourage pathogens. Too much grease can also slow down or even halt the compost action.

Will you pick up my turkey grease?

We are not able to collect used cooking oils from homes. To adhere to sourcing and tracking requirements of the materials we use in the fats, oils, proteins and greases we produce, our company can only collect from contracted customers. Check with your city or local firefighters. During the holidays, there are often special drop-off spots for the grease that deep fried that yummy turkey on your Thanksgiving table.

Do you recycle motor oil?

No, we only recycled used cooking oils from businesses, industrial, institutional and commercial establishments. If you have motor oil to discard, contact your city or local automotive retailer and ask if they have drop off locations. Many cities offer periodic hazardous waste collection days; store your old motor oil safely and drop it off at those events. Motor oil contains chemicals that could be dangerous to groundwater, vegetation, or water supplies, so should never be poured onto the ground or down a drain.
