Who Buys Used Cooking Oil?
Used cooking oil, also known as waste cooking oil (WCO), is a valuable resource that can be transformed into various products. It is estimated that the United States alone generates over 6 billion pounds of WCO annually. So, who buys used cooking oil and what do they do with it?
Biodiesel Producers
Biodiesel: A Renewable Energy Source
Biodiesel is a renewable energy source that is made by combining WCO with other ingredients and processing it into a diesel fuel substitute. Biodiesel producers purchase WCO from restaurants, food processing facilities, and other industries that generate large amounts of used cooking oil. The WCO is then refined and converted into biodiesel, which can be used as a cleaner-burning alternative to traditional diesel fuel.
Table 1: Benefits of Biodiesel
| Biodiesel | Traditional Diesel Fuel | |
|---|---|---|
| Emissions | Greenhouse gas emissions: 68% reduction, particulate matter: 47% reduction, nitrogen oxides: 20% reduction | |
| Performance | Comparable to traditional diesel fuel | Higher emissions, poorer performance |
| Cost | Competitive price with traditional diesel fuel | Higher cost |
Biodiesel Production Process
The biodiesel production process involves several steps:
- Collection and sorting of WCO
- Pre-treatment of WCO (filtration, degumming)
- Transesterification (conversion of WCO into biodiesel)
- Filtering and purification
- Blending with diesel fuel
Animal Feed Manufacturers
Animal Feed: A Valuable Resource for Livestock
Animal feed manufacturers also purchase WCO to produce animal feed products. The WCO is rendered and processed into various feed products, such as animal meal and animal fat, which are used as a nutritious supplement for livestock.

| Animal Meal | Animal Fat | |
|---|---|---|
| Composition | Protein-rich, fiber-rich | Energy-rich, fatty acid-rich |
| Applications | Poultry feed, swine feed, cattle feed | Poultry feed, swine feed, aquaculture feed |
Cosmetic and Soap Manufacturers
Cosmetics and Soaps: A New Life for Used Cooking Oil
Cosmetic and soap manufacturers purchase WCO to produce various personal care products, such as soaps, lotions, and creams. The WCO is processed into glycerin, which is a key ingredient in many personal care products.

| Soaps | Lotions | Creams | |
|---|---|---|---|
| Ingredients | Glycerin, moisturizing agents, pH adjusters | Glycerin, moisturizing agents, emollients | Glycerin, moisturizing agents, humectants |
Biofuels and Chemicals
Other Uses for Used Cooking Oil
Used cooking oil can also be converted into other biofuels, such as ethanol and methanol, or used as a feedstock for the production of chemicals, such as biodegradable plastics and detergents.
Conclusion
Used cooking oil is a valuable resource that can be transformed into various products. Biodiesel producers, animal feed manufacturers, cosmetic and soap manufacturers, and other industries purchase WCO to produce a range of products, from renewable energy sources to personal care products. The benefits of recycling used cooking oil are numerous, including reduced greenhouse gas emissions, improved air quality, and a reduction in waste disposal costs. As the demand for sustainable and environmentally friendly products continues to grow, the market for used cooking oil is expected to expand, providing new opportunities for entrepreneurs and industries alike.
