The state’s largest biodiesel producer gave a glimpse into the continued expansion of its local plant Wednesday, as it continues attempting to increase its production by 50 percent.

Crimson Renewable Energy, located south of Highway 223 in southwestern Kern County, is in the process of creating a facility designed to distill and purify the biofuel it produces from a variety of used oils and animal fats. The project began in December 2019 and is expected to be operational by summer 2021, according to Chris Dixon, Crimson’s quality manager.
