Pizza Pizza Ltd. is collecting electronic waste products for recycling from customers in exchange for a free slice of pepperoni pizza.

The Toronto-based pizza chain said for April it is widening the scale of its Cells for Slices campaign, offering the giveaway in its 365 traditional Canadian restaurant locations in Ontario, Winnipeg and Regina, according to a news release.

The food retailer will recycle the products turned in, and all proceeds from the recycling will go the Toronto-based Food Banks Canada as part of its Phones for Food program. Electronic devices eligible for the program include mobile and smart phones, cameras, adapters, tablets and iPods.

"We're offering an easy way for people to dispose of their old and unwanted devices in a way that rewards our customers," said Pat Finelli, chief marketing officer for Pizza Pizza.

Pizza Pizza’s Cells for Slices program has collected more than 5,600 used mobile devices since being launched in 2004. The company said it has saved more than 1.25 million trees in the past 12 years by using 100-percent recycled paper for its pizza boxes.

The Phones for Food program has diverted about 500,000 wireless devices from landfills since its inception in 2003.
