What Is Yellow Grease?

Yellow Grease is obtained from the used cooking oil that remains after food is deep-fried. The term also refers to lower grades of cow or sheep tallow available from animal rendering plants. Yellow grease is different from brown grease, which accumulates in drain lines, grease traps and interceptors. Because brown grease contains a mixture of gray water, animal fats and vegetable oils, the spent oil is not suitable for reuse.

Yellow grease must undergo a chemical process known as transesterification to become biodiesel. The reaction separates the molecules into smaller parts, which lowers the thickness and makes the product a practical alternative fuel for diesel engines.

In addition to biodiesel, manufacturers use yellow grease to produce clothing, detergents and rubber. The product contains essential fatty acids that supplement the nutritional value of animal feed as well.

The National Biodiesel Board (NBB) reports that biodiesel produces four times more energy than is required to manufacture the product. In addition to supplying fuel, biodiesel lubricates moving parts in automotive engines, which eliminates the use of petroleum-based products that contain sulfur.

Less than 40 percent of the United States’ oil products are produced in the country. The NBB suggests that biodiesel can create tens of thousands of jobs and add millions of dollars to the national economy. Because biodiesel is a domestic fuel, it can also reduce the country’s reliance on imported oil. Biodiesel production can boost the farming industry while creating new green jobs and lowering the nation’s carbon footprint.

What are the Benefits of Biodiesel?

Environmental programs and economic concerns have increased the interest in alternative sources of fuel. Biodiesel is a great way to improve the nation’s environment and economy. The fuel is a biodegradable product that provides significant benefits whether used individually or in combination with petroleum-based diesel fuels.

Biodiesel has a lower impact on the environment because it consists of renewable resources. The product has minor traces of sulfur and nearly 80 percent less carbon emissions than conventional diesel fuels when used alone. The fuel lowers the level of dangerous toxins released into the air, such as carbon dioxide, particulate matter and unburned hydrocarbons, when mixed with petroleum-based diesel products.

The U.S. government mandated that petroleum-based diesel fuels have lower sulfur content. Decreasing environmental pollutants has an overall health benefit for society because it reduces exposure to harmful chemicals, which can cause or worsen medical condition, such as respiratory ailments and cancer. Recycling yellow grease to produce biofuel reduces the burden on disposal sites as well.
