What goes around comes around at Cavendish Farms' plant 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 metric tons—the equivalent of taking 7,300 cars off the road for one year.

"We were burning about 10 million liters (about 2.6 million gallons) per year of Bunker C fuel oil," said Darren Cash, manager of safety and environmental operations at the plant.

The company further reduced its oil consumption in 2012 in the fry plant by switching the remainder of its fuel oil to natural gas.

"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.
