Cooking oil is an integral part of every kitchen, but disposing of it after use can pose a challenge for households and restaurants. Pouring it down the drain may seem convenient, but it can cause clogged pipes, sewage backups, and costly repairs.
Learning how to recycle used cooking oil gives you a better option. With proper handling, storage, and collection, oil that is no longer suitable for cooking can become a resource for producing biodiesel and other useful products.
Below, we explain how to recycle used cooking oil in Ohio, which materials recycling programs accept, and how Green Mountain Products can help you establish a dependable collection system.
Why Should You Recycle Used Cooking Oil?
Used cooking oil still has value after it leaves your kitchen. The U.S. Department of Energy identifies used cooking oil and yellow grease as materials used to produce biodiesel.
Recycling cooking oil offers several benefits:
- Protecting your plumbing: Keeping oil out of drains helps prevent blockages in your pipes and the surrounding sewer system.
- Supporting renewable fuel production: Collected cooking oil can be processed into biodiesel, giving it another useful purpose.
- Reducing waste: Recycling allows suitable oil to be recovered rather than discarded.
- Improving kitchen operations: A dedicated storage container and regular collection schedule give businesses a practical way to manage used oil.
Whether you produce a small amount at home or larger quantities in a commercial kitchen, proper collection is the first step.
How to Recycle Used Cooking Oil: Step by Step
Recycling used cooking oil starts before it reaches a processing facility. Following these steps helps you prepare your oil for collection while preventing spills and contamination.
1. Check What Your Recycling Provider Accepts
Before collecting oil, contact your local recycling program or cooking oil collection company. Ask which oils they accept, whether they serve households or businesses, and what containers you should use.
You should also confirm any quantity limits, fees, appointment requirements, and drop-off instructions. Not every recycling location accepts cooking oil, and a facility that collects motor oil may have different rules.
The USDA recommends checking with your local collection point to confirm whether it accepts used cooking oil.
2. Let the Cooking Oil Cool
For household quantities, allow the oil to cool completely before transferring it into a storage container. Hot oil can cause burns and damage containers that are not designed to hold it.
Commercial kitchens should follow their equipment manufacturer’s and collection provider’s instructions for safely transferring fryer oil. Use equipment intended for the task rather than carrying hot oil in an unsuitable container.
3. Remove Leftover Food Particles
Strain cooled household cooking oil to remove crumbs, herbs, and other food debris. A suitable strainer can help separate these solids before you store the oil.
For commercial quantities, ask your collection provider about its preparation requirements. Removing food particles helps keep the collected oil suitable for processing. For example, Queen Creek’s cooking oil recycling program instructs participants to strain their oil before bringing it to collection receptacles.
4. Store the Oil in a Secure Container
At home, pour cooled oil into a clean, dry, leak-proof container with a tight-fitting lid. Label it “Used Cooking Oil” so it is easy to identify and cannot be confused with fresh oil.
For commercial kitchens, use a dedicated used cooking oil collection container. Work with your provider to select a size that matches your kitchen’s output and keep the lid secured between collections.
Here at Green Mountain Products, we work with customers to determine the appropriate container size and service frequency for their used cooking oil.
5. Keep Other Substances Out
Do not mix used cooking oil with water, cleaning chemicals, motor oil, fuels, sauces, or other waste.
These materials can contaminate the oil and may prevent a recycling facility from accepting it. The Town of Cary’s collection guidelines specifically exclude water, chemicals, detergents, and other contaminants.
For businesses, make sure everyone who uses the collection container understands what belongs in it.
6. Arrange Collection or Use an Approved Drop-Off Location
Once the oil is ready, follow your provider’s instructions for pickup or drop-off. Confirm the location’s current hours and requirements before transporting household oil, and keep the container closed and upright during the trip.
Businesses that generate oil regularly should establish a collection schedule that prevents containers from becoming overfilled.

What Types of Cooking Oil Can Be Recycled?
Many cooking oil recycling programs accept vegetable-based oils, including:
- Vegetable oil
- Canola oil
- Olive oil
- Peanut oil
- Sunflower oil
- Corn oil
- Soybean oil
Acceptance depends on the collection program and the condition of the oil. Check with your provider before combining different oils or adding other cooking fats.
Can You Recycle Lard and Bacon Grease?
Lard should not be recycled with liquid cooking oil unless your recycling provider specifically accepts it. The same approach applies to bacon grease, shortening, and other solid cooking fats.
Some programs collect only liquid cooking oil and exclude solid fats. Others accept animal fats, including lard. For example, Natick’s recycling program excludes lard, while Santa Clara County’s program accepts it.
Keep these materials separate until you confirm your provider’s requirements. Never pour lard, bacon grease, or cooking oil down the drain.
Recycling Used Cooking Oil at Home
Household cooking oil recycling depends on the services available in your community. Contact your city, county, or local solid waste district to ask about collection locations and accepted materials.
Explain that you have used cooking oil, rather than simply “used oil,” so you receive instructions for the correct material.
If recycling is unavailable, follow your local waste authority’s disposal guidance. The USDA advises placing unwanted household cooking oil in a sealed container for disposal rather than pouring it into a sink.
Recycling Used Cooking Oil in Commercial Kitchens
Restaurants, grocery stores, and other commercial kitchens need a collection system that can handle larger quantities of oil.
A dependable system should include a dedicated storage container, clear instructions for employees, and pickups scheduled around the amount of oil your business produces.
It is also important to distinguish a used cooking oil container from a grease trap. Fryer oil should be collected directly for recycling. A grease trap or interceptor captures fats, oils, and grease from wastewater and requires its own maintenance. It should not be used as a disposal route for bulk fryer oil.

Frequently Asked Questions About Used Cooking Oil
Q: Can You Pour Cooking Oil Down the Drain?
A: No. Cooking oil and grease can accumulate in pipes and contribute to blockages. Collect the oil separately and follow your recycling provider’s or local waste authority’s instructions.
Q: Can Dirty Cooking Oil Be Recycled?
A: Often, yes. Used cooking oil does not need to look like fresh oil to have recycling value. However, remove food debris as directed and keep water, cleaning chemicals, and other contaminants out of the collection container.
Q: Does Cooking Oil Go in Your Regular Recycling Bin?
A: Do not place oil-filled containers in your regular recycling bin unless your local program specifically instructs you to do so. Used cooking oil generally requires a dedicated collection service or approved drop-off location.
Q: What Happens to Cooking Oil After Collection?
A: Collected oil is prepared for further processing, which can include removing food solids, water, and other impurities. Suitable oil can then be used to produce biodiesel and other products.
