The Torrance company that recently bought the former Big West refinery on Rosedale Highway said Tuesday it expects to reopen the plant by early 2022 with about 100 employees producing some 10,000 barrels per day of plant-based "renewable diesel," a fuel virtually indistinguishable from petroleum-derived diesel.

Global Clean Energy Holdings Inc. said its initial feedstock will be used cooking oil brought in primarily from Southern California. But eventually it plans to transition to using a crop called camelina, an inedible crop grown as ground cover for wheat fields in off years.
