French-Fry Plant Is Fuelled By Potato Scraps

What goes around comes around at Cavendish Farms in New Annan, P.E.I. — potato scraps from the french-fry plant are used at the nearby biogas facility to fuel the fry factory they came from.

According to the company, generating biogas allowed it to reduce its dependency on fuel oil by 30 per cent, reducing greenhouse gases by about 35,000 tonnes — the equivalent of taking 7,300 cars off the road for one year.

“We were burning about 10 million litres per year of Bunker C fuel oil,” said Darren Cash, manager of safety and environmental operations.

“We were burning about 10 million litres per year of Bunker C fuel oil,” said Darren Cash, manager of safety and environmental operations.

“We’ve actually been able to reduce our carbon footprint by 60 per cent,” said Cash.

Fewer trucks on the road

Cash said using the waste to create biogas also means the company isn’t trucking about a dozen loads of potato waste offsite every day — as it used to.

“So the peel, the raw material, the frozen product that’s not fit to go into a bag would all have been trucked offsite to animal feed lots,” he said.

Now, any leftover waste is turned into compost. It is still trucked offsite — sometimes to be used in the same potato fields it originally came from — but Cash said it’s now only one truck a day and reducing mileage by 1,450 kilometres per day.

“It’s a great story for a lot of reasons,” Cash said. “Taking those trucks off the road makes a big impact and also burning a cleaner fuel lowers our carbon footprint on site.”

‘A showpiece plant’

The $25 million biogas facility has been in operation for almost 10 years, and Cash said its technology is still considered state of the art today.

“It’s still a showpiece plant,” he said. “The construction of this plant would stand up — you’d do it almost the same way today, almost ten years later.”
