Diamond Green Diesel beginning production of renewable diesel

Diamond Green Diesel (DGD), the joint venture between Valero subsidiary Diamond Alternative Energy LLC and Darling International Inc., has reached mechanical completion and the startup process will lead to full production of renewable diesel. (Earlier post.)

Once in full operations, the 9,300 barrel-per-day plant will process recycled animal fat and used cooking oil as well as corn oil into renewable diesel fuel that has comparable properties to petroleum-based diesel using the UOP hydrotreating process. The renewable diesel can be shipped by pipeline and meets low-carbon fuel standards.

In DGD’s Low Carbon Fuel Standard application package to the California ARB, ARB staff notes that the carbon intensity of the renewable diesel will range from approximately 5.56 gCO2e/MJ to 83.70 gCO2e/MJ (including indirect effects), depending upon the type of feedstock, processing and transport required. The standard diesel baseline is 98.03 gCO2e/MJ.

Darling International Inc. is the largest and only publicly traded provider of rendering and bakery residuals recycling solutions to the nation’s food industry. The company recycles beef, poultry and pork by-product streams into useable ingredients such as tallow, feed-grade fats, meat and bone meal, poultry meal and hides. The company also recovers and converts used cooking oil and commercial bakery residuals into valuable feed and fuel ingredients.

In addition, the company provides grease trap collection services and sells used cooking oil collection equipment to restaurants.
