The Diamond Green Diesel facility in Norco is expected to return to production next week, according to joint-venture partner Darling Ingredients.
The facility has been shut down since an explosion and fire on Aug. 3. Darling said the start-up process began on Sept. 15. No one was injured in the blast.
Diamond Green, a joint-venture between Darling and Valero Energy Corp., makes diesel from used cooking oil and other feedstocks.
