How Canadian Technology Is Tackling The Food Waste Crisis

How homegrown Canadian tech is tackling our $31 billion food waste crisis.

The issue of food waste has grown from your parents telling you to finish what's on your plate into one of the defining challenges of our era. Despite rising food insecurity, $31 billion of it is wasted every year in Canada, a number soaring to $1 trillion worldwide as 30 per cent of food goes uneaten.

Yes, some of that is still your fault if you put leftovers in the trash instead of Tupperware, but the vast majority of food waste happens at production, processing and retail levels rather than on the consumption side.

To help address this, France famously passed unanimous legislation requiring supermarkets to either give unsold food to charity or send it to farmers for use as feed and fertilizer. Here in Canada, food rescue organizations like Second Harvest help get unspoiled food from retailers, manufacturers, restaurants and caterers to charities, delivering ingredients for over 22,000 meals daily.

But we live in hi-tech times, so technology is also being used as a weapon in the war on food waste. Here's a look at how homegrown Canadian tech is trying to tackle our food waste crisis.
