How to Dispose of Used Cooking Oil

In the hustle and bustle of a commercial kitchen, managing used cooking oil can often be an afterthought. However, proper disposal of this common kitchen byproduct is crucial for maintaining a clean and efficient operation.

If you run a commercial kitchen, you’re likely familiar with the role of a grease trap in controlling oil and grease output. As a refresher, check out our article on how grease traps work and the difference between a grease trap and grease interceptor.

Read on for a brief guide on environmentally responsible ways to dispose of used cooking oil (sometimes referred to as UCO)—for both residential and commercial kitchens.

Why You Can’t Pour Cooking Oil Down the Drain

Pouring used cooking oil down the drain might seem like a quick and easy solution, but it comes with a host of problems.

Clogged Pipes

The most immediate concern is the potential for clogged pipes. As the oil cools and solidifies, it can create blockages, leading to expensive plumbing issues. Over time, these blockages can accumulate, causing backups and even damage to the municipal sewage system.

Likewise, you shouldn’t just dump used cooking oil in the trash. It goes without saying that cleanup could get really messy. You also risk bad smells and attracting pests.

Environmental Impact

Beyond the impact on your kitchen’s plumbing, pouring used cooking oil down the drain has severe consequences for the environment. When grease enters water systems, it can coat aquatic life and disrupt the balance of ecosystems. Additionally, the process of treating water contaminated with grease is both costly and energy-intensive for water treatment facilities.

Commercial vs. Residential Kitchens

Naturally, there are distinct requirements for commercial kitchens that don’t necessarily apply to residential kitchens—making it important to know what approach is best in your situation. In this case, your city’s official website is your friend. Take a look at the city of Houston’s guide to recycling used cooking oil for example.

In commercial kitchens, the sheer volume of cooking oil used on a daily basis requires a more robust disposal strategy. Since most commercial kitchens are governed by city codes, they are often legally required to have grease traps installed and serviced regularly. That’s where grease trap cleaning services come in, which we’ll cover later on.

Proper Cooking Oil Disposal Methods

Fortunately, there are responsible and eco-friendly methods for disposing of used cooking oil that not only safeguard your plumbing but also contribute to a more sustainable future. Let’s explore these proper disposal methods and learn how simple choices in your kitchen can make a significant impact on the environment.

The main methods for proper disposal of cooking oil are:

• Recycling centers
• Local collection programs 
• Reuse

Recycling Centers

One of the most environmentally friendly methods is to recycle used cooking oil. Many recycling centers and local waste management facilities accept used cooking oil. They can repurpose it into biofuel, reducing our reliance on non-renewable energy sources.

Using Houston as an example again, you can find a recycling center directory that advises folks on where they can recycle their used oil. All you need to do is wait for the oil to cool, bottle it, and bring it to a designated recycling location.

Local Collection Programs

Some communities offer collection programs specifically for used cooking oil. Check with your local municipality or waste management facility to see if such programs exist in your area. Certain pickup programs are generally reserved for larger operations like restaurants, but a quick search for “local cooking oil collection” should reveal some options.

Yes, You Can Reuse Cooking Oil!

If the oil is still in good condition, consider reusing it for future cooking. However, it’s important to consider and prevent cross contamination when doing so. Strain out any food particles and store the used cooking oil in a sealed container for later use. This not only saves you money but also minimizes waste.
