Competition for waste cooking oil to convert into car fuel is so stiff that suppliers are beginning to look overseas for supplies - which could push up the price for consumers.
Wellington company Envirocar manufactures a conversion kit that allows vehicles to run on environmentally friendly vegetable oil, which isgathered from restaurants and fast food outlets and recycled into a fuel.
Car conversion costs just under $4000 and means the vehicle can run on diesel, recycled or new plant oil, bio diesel or a combination of the options. Envirocar director Robert Kornfeld said the company was importing small amounts of test oil from the Indian subcontinent and Africa, and researching the viability of growing plants for fuel oil in New Zealand.
