A Japanese company will invest $800 million to plant castor beans and refine castor

oil into bio-diesel fuel. The Biwako Bio-Laboratory Co, Ltd will plant castor beans

on 48,000 hectares of land in Kampong Speu and Kampong Cham provinces and then establish

a factory to refine castor oil into bio-diesel as a gasoline substitue, CEO Mitsuo

Hayashi told local media. The 48,000 hectares of castor plants can yield 100,000

tons of castor oil annually and 40,000 tons of bio-diesel after refinement.
