A commercial vegetable grower on Rarotonga in the Cook Islands is recycling canola oil as fuel for its vehicles.
The president of Titikaveka Agricultural Association, Teava Iro, says they want to be more sustainable in their fuel use, in the same way, they aim to reduce the country's food imports.
He says the oil is what restaurants and take-away bars want to discard.
Mr Iro says the company is refining the oil but he is still experimenting on the best way to do this.
He spoke with Don Wiseman who began by asking about the focus of Titikaveka Agricultural Association's growing efforts.
