Diamond Green Diesel
One of the world's largest producers of renewable diesel, our 50/50 joint venture Diamond Green Diesel (DGD) produces low-carbon renewable fuel that is 100% compatible with existing engines and infrastructure. Renewable diesel utilizes recycled animal fats and used cooking oil, some of which are supplied by our Feed segment, to produce low-carbon intensity fuel with up to 80% fewer lifecycle greenhouse gas emissions than traditional fuel.
At a glance
The renewable diesel process
1. Feedstock
Rendered recycled animals fats and used cooking oil feedstocks, some of which are supplied by our Feed segment, are delivered to DGD via rail, trucks or ships.
2. Processing
First, feedstocks are treated to remove impurities. Then, hydrotreating with high-pressure hydrogen to remove oxygen and separate water. Next is isomerization, where cold-flow properties are managed to ensure compatibility with existing infrastructure and engines. Finishing involves fractionation, or separation, into finished products.
3. Distribution
Finished renewable diesel is stored for shipping to customers, primarily in low-carbon markets such as California, Canada and Europe. Renewable diesel can be transported via pipeline, rail or ship.
Sustainable aviation fuel
Upgrading sustainable fuel for aviation
Diamond Green Diesel’s next phase of growth is in the aviation market. With updates to the Port Arthur, Texas plant, DGD will have the capability to upgrade approximately 50 percent of the facility's current 470 million gallon annual production capacity to sustainable aviation fuel (SAF).
At completion of this project, DGD is expected to become one of the largest SAF manufacturers in the world.

Renewable fuel for a low-carbon world
Integrated supply chain
Our Feed segment supplies DGD with recycled animal fats and used cooking oil, making DGD the world's only vertically integrated producer of renewable diesel.
Lowering emissions without modfications
In early 2023, we announced the final investment decision on a Sustainable Aviation Fuel (SAF) project at our Port Arthur, Texas, facility. Targeted for completion in 2025, the project will allow approximately 50 percent of the plant’s nameplate capacity of 470 million gallons per year to be upgraded to SAF. This is expected to make DGD one of the largest SAF manufacturers in the world.
Positioned to meet global demands
Since 2013, DGD has been North America’s largest producer of renewable diesel from low-carbon feedstocks, providing customers with a reliable and sustainable alternative to traditional fossil fuels.
Fuel of the future
Helping to decarbonize the world
Renewable diesel is made from responsible and sustainable feedstock, such as used cooking oil, rendered animal fats and inedible corn oil. It is molecularly the same as petroleum-based diesel and it meets the ASTM International’s standard for Diesel Fuel Oils (D-975).
Diamond Green Diesel is strategically positioned to fulfill US renewable fuel standards and address global market needs. From an initial annual production capacity of 160 million gallons, DGD has expanded to 1.2 billion gallons per year since coming online in 2013.
Low carbon fuel standards
DGD's renewable diesel is 100% compatible with engines designed for petroleum-based diesel. This versatile, drop-in fuel can be transported directly via pipeline, rail or ocean carrier.
Renewable fuel produced at Diamond Green Diesel meets the most stringent low-carbon fuel standards. It is primarily sold in the large California on-road diesel fuel market to comply with the state’s Low Carbon Fuel Standard. DGD also sells significant volumes to Canadian and European customers to comply with their fuel requirements.
