What is used cooking oil, and what do you do with it? If you’re opening or expanding a restaurant, you may be asking this question for the first time ever.  

Restaurant management is a complicated game. There are the obvious players:  menus, ingredients, staff, and customers. You planned on these. But there are also many aspects that are much less noticeable, though just as important. Equipment, legal compliance, grease trap maintenance, food waste management—the list goes on. Properly disposing of your used grease is just one of the many vital tasks that no one ever told you about. It gets overwhelming, fast.  

At DAR PRO Solutions, we think of a restaurant back-of-house like a crowded party. We’re the face you probably don’t recognize, but our work helps make yours possible. As North American leaders in used cooking oil recycling (handling 50% of all UCO across the United States), we take pride in making restaurant management easier.   

If you’re wondering how to handle your cooking oil once it’s been in the fryer, or why it even matters, you’ve come to the right place. Here’s our complete guide to understanding and recycling your restaurant’s used cooking oil with DAR PRO.


What is Used Cooking Oil,  and Why Should You Care About It?  

Put simply, used cooking oil (UCO) is any grease, oil or fat that has finished its lifecycle as a cooking ingredient. Once oil has been in the fryer for a certain number of uses, it compromises the safety and taste of food. It needs to be disposed of and replaced. Restaurants go through more than almost any industry, using a wide variety of oils and fats to serve up tasty meals. 

After cooking, restaurants are responsible for safely disposing of their grease. Exact regulations vary from state to state, but you will be expected to keep pipes clear and avoid contaminating the area around your business.     

Though sometimes seen as a waste product, UCO doesn’t have to be. In fact, it has more potential than most other recyclable materials. From home kitchens to food processing plants, many people and industries cook with oil.  

The recycling opportunity is staggering. Just imagine, if your restaurant's fryer holds 80 lbs. of oil and you change the oil 2 times per week, you have the potential to recycle approximately 8,000 lbs annually. That's the equivalent of diverting 2,689 bags of trash from the landfill.


Why You Should Recycle UCO?

We all know that it’s a good idea to recycle as much as possible. When you repurpose a product that would otherwise end up in wastewater or a landfill, you relieve the demand for new materials and save valuable resources.   

That said, you don’t need a passion for sustainability to recycle your kitchen’s waste products. Experienced food industry businesses know that recycling your cooking oil with a responsible partner solves a world of logistical and compliance problems. Here are just a few of the top reasons why recycling your used cooking oil will benefit your business and the environment.

It’s Good for Your Business (and Ultimately, Your Wallet)  

When your waste ingredients are being automatically disposed of, you have more time to focus on running your restaurant. You will also save on repairs and fines—an all-too-common side effect of pouring your grease down the drain or throwing it out irresponsibly.  

It’s Good for the Environment  

When it’s dumped, used cooking oil is just another waste product. It’s a shame this ever happens, since UCO can be easily recycled as an ingredient in a wide array of highly-valuable products. One of the most important of these is renewable fuel. Also called “renewable diesel” or “green diesel,” it helps reduce our world’s reliance on fossil fuels. It also burns cleaner than traditional fuels, causing less atmospheric pollution. 

It’s Good for Your Reputation  

It just feels good to support ethical and sustainable businesses. We live in an increasingly eco-conscious world, and consumers are voting with their dollars, even when choosing where to go for dinner. Recycling your used cooking oil is just one way to show your customers what your values are. It might also be the most convenient sustainability practice you ever implement.

You Don’t Want to Dispose of It Yourself  

This might be the most important factor to consider. Disposing of cooking oil without a recycling partner leaves you with all of the responsibility, and very few options.   

These options can seem simpler than recycling when you’re strapped for time. But they can actually cause more complications, some of which are very expensive. Here’s why you’re better off recycling through a trusted partner.
