    Biodiesel is a non-toxic biodegradable diesel fuel substitute

Biodiesel is a non-toxic biodegradable diesel fuel substitute produced from renewable sources such as vegetable oils, animal fats, and recycled cooking oil. It is the only EPA advanced clean-burning alternative fuel which, when used in place of, or in blends with, petroleum diesel can reduce greenhouse gas emissions by as much as 78%.

By collecting these used oils from restaurants and other facilities, One More Time helps stop these materials from going down the drains, which prevents sewer blockages and overflows that can pollute our streets and waterways.

How It Works

One More Time collects used cooking oil from local restaurants, hotels, schools, hospitals, casinos, and other industrial kitchens throughout California. It sends its “yellow grease” (recycled vegetable oil from deep fryers), to New Leaf Biofuel, a sister company to One More Time. Once the oil is cleaned up and settled, it is pumped into a biodiesel processor where operators work 24/7 to manufacture that oil into high quality biodiesel fuel. The raw ingredients are turned into biodiesel through a chemical process called “transesterification” that replaces the glycerin with three methanol molecules that attach to the fatty acids from the fat molecule. This separates out glycerin for use in soaps and other products and leaves behind Fatty Acid Methyl Esters (FAME), which is the technical term for biodiesel.

Renewable Diesel

Renewable diesel can also be made by taking used cooking oils, tallow, yellow grease, and other recycled and rendered products and processing them as is, or in combination with crude petroleum to make a diesel fuel. This renewable diesel fuel meets the same fuel specs as petroleum diesel but is much more environmentally friendly.

Greenhouse Gases

Once the finished product is pumped out into holding tanks, it is then sold to local fleets and distributors. These fleets are using biodiesel blended with diesel in their engines, which directly displaces diesel fuel usage, thus reducing greenhouse gas emissions by up to 80% and allowing everyone to breathe a little easier!

Carbon Intensity by the Numbers

In California the Air Resources Board (ARB) has a Fuels Evaluation section that is responsible for accessing and developing transportation fuels for the California Low Carbon Fuel Standard (LCFS) as well as conducting lifecycle analysis of Greenhouse Gas (GHG) emissions. When they compare fuels they assign a Carbon Intensity (CI) number which measures the average emission rate of a given pollutant. As of 2014 these CI numbers are:bio-abstract-2-300x213

Petroleum Gasoline = 97.47
Petroleum Diesel = 96.56
Biodiesel from Used Cooking Oil = 11.76-15.80
Renewable Diesel from Tallow = 19.65-39.33

So you can see that renewable fuels made from recycled products from renderers are a much kinder to the environment than standard petroleum fuels.
