It’s an issue that’s estimated to cost Canada more than $21 billion per year -- nevermind the environmental impacts. But how much thought have you really given to the problem of food waste and spoilage, and how it could be hampering our country’s effort to reduce emissions? Whenever wasted or spoiled food ends up buried in a landfill instead of decomposing while exposed to air, it generates methane — a potent greenhouse gas with 86 times the warming power of carbon dioxide. And it just so happens that Canada is one of the worst countries on the planet when it comes to wasted food. So what can be done about it?

On this episode of Disruptors, an RBC podcast, co-hosts John Stackhouse and Trinh Theresa Do wrap up their special, three-part series called “The Growing Challenge”, with an in-depth examination of how both food waste and spoilage represent a huge and often overlooked obstacle to our nation’s sustainability efforts. They’ll also discuss new technologies and tactics helping food producers to address the issue — as well as how we as consumers all need to change our attitudes when it comes to things like best before dates, portion sizes, and so-called “rescued food.”

In addition to some familiar voices from earlier episodes in the series like Sonya Hoo, Evan Fraser, and Kristjan Hebert, John and Theresa will also hear from Meeru Dhalwala, author, chef, and the co-owner of Vij’s and Rangoli restaurants in Vancouver; Randy Huffman, the Chief Food Safety and Sustainability Officer at Maple Leaf Foods; Kevin Groh, Senior Vice President of Corporate Affairs at Loblaw Companies Limited; as well as Jeremy Lang, the founder and Vice-President of Sustainability at Pela Earth, which makes a smart, countertop-based composting system called Lomi.
