Biodiesel - America's Advanced Biofuel

Biodiesel is a renewable, clean-burning diesel replacement that is reducing U.S. dependence on foreign petroleum, creating jobs and improving the environment. It is made from a diverse mix of naturally occurring oils and fats, including waste oils. Meeting strict technical fuel quality and engine performance specifications, it can be used in existing diesel engines without modification and is covered by all major engine manufacturers’ warranties, most often in blends of up to 5 percent or 20 percent biodiesel.


Increasing consumption of Biodiesel significantly lessens U.S. dependence on imported oil, bolstering national security and reducing our trade deficit. At the same time, biodiesel’s growth boosts the U.S. economy, not just by creating jobs but also by reducing our dependence on global oil markets and vulnerability to price spikes.


The EPA has recognized biodiesel’s environmental benefits by classifying it as an Advanced Biofuel. According to the EPA, biodiesel reduces greenhouse gas emissions by at least 57 percent and up to 86 percent (using recycled waste oils) when compared to petroleum diesel – making it one of the most practical and cost-effective ways to immediately address climate change. In addition, biodiesel sharply reduces major tailpipe pollutants from petroleum diesel, particularly from older diesel vehicles. This is important because the EPA has consistently cited diesel exhaust – primarily from older trucks, buses and other vehicles – as one of the nation's most dangerous pollutants.


Biodiesel is better for the environment because it is made from renewable resources and has lower emissions compared to petroleum diesel. It is less toxic than table salt and biodegrades as fast as sugar. Produced domestically with natural resources, its use decreases our dependence on imported fuel and contributes to our own economy.


Southeast Biodiesel, LLC

Since 2007, Southeast Biodiesel LLC has produced biodiesel at our North Charleston, SC, manufacturing facility. Constructed on brownfield property on the former Charleston Navy Yard our facility is capable of converting up to 5,000,000 gallons per year of waste cooking oils and other waste feedstocks into high quality fuel suitable for use in all diesel vehicles and engines.

We have a highly qualified and experienced operations team and are engaged in a program of continuous improvement and expansion of our production. 


Although biodiesel can be made from vegetable oil, its finished properties are very different. Raw vegetable oil cannot meet biodiesel fuel specifications, it is not registered with the EPA, and it is not a legal motor fuel. In the biodiesel manufacturing process glycerol is removed and a new injector-friendly mono-alkyl ester is created. This must comply with strict industry specifications (ASTM D6751) in order to ensure proper performance. Biodiesel that meets ASTM D6751 and is legally registered with the Environmental Protection Agency is a legal motor fuel for sale and distribution. 


Southeast Biodiesel’s fuel is registered with EPA and complies with all technical and quality requirements of ASTM D6751. Our commitment to integrity and quality is backed up by a diverse range of external agencies and partners.
