Up to 12,000 barrels of renewable diesel every day - and growing
Diamond Green Diesel is one of the world’s pioneering renewable energy projects. It is a sustainable biofuel facility that is helping meet America’s growing renewable energy demands. At the Diamond Green Diesel refinery in Norco, Louisiana, we produce at capacity, up to 12,000 barrels of renewable diesel every day.
An outstanding carbon lifecycle performance
The Norco plant converts approximately 1.3 billion pounds of fats and oils into approximately 160 million gallons of green diesel per year, and is currently expanding production to 275 million gallons annually by the start of 2018. Renewable diesel is a molecular match to petroleum-based diesel fuel and can be dropped into the pipeline for distribution. Importantly, our biofuel has a carbon life cycle low enough to meet the most stringent low-carbon fuel standards in effect today. Diamond Green Diesel's renewable diesel meets the requirements of California's Low Carbon Fuel Standards (LCFS), which mandates the lowering of greenhouse gas emissions of at least 10% by 2020 in an effort to lower the carbon footprint of transportation.
Creating resources, not depleting them
Our biofuels are made from food residuals – animal fats, used cooking oil and other feed stocks. Rather than placing these materials in landfills or putting them to no use, we are producing sustainable fuel without diminishing the world's food supply, using fertile land space, or diminishing nature’s resources.
In short, Diamond Green Diesel creates, rather than depletes, resources our growing world needs.
Biofuels like Diamond Green Diesel can reduce greenhouse-gas emissions, improve energy security and bring jobs and investment opportunities
A superior product with a higher cetane index
Like conventional diesel, Diamond Green renewable diesel is a hydrocarbon that meets ASTM International’s standard for Diesel Fuel Oils (D-975).
- Renewable diesel’s molecular structure differs from that of biodiesel, which is a methyl-ester
- Renewable diesel is superior to typical ultra-low sulfur diesel (ULSD), having a higher cetane index
- Unlike biodiesel, renewable diesel has an energy density value equivalent to ULSD
- Renewable diesel can be distributed through the established petroleum pipeline system, while biodiesel requires truck or rail transport
- Renewable diesel has no cold-flow issues and won’t thicken and clog engines in cold weather
Diamond Green Diesel began as a joint venture of Darling Ingredients and Diamond Alternative Energy LLC, a subsidiary of Valero Energy Corporation. It was our first move into the mass-scale production of renewable diesel.
