In the US alone, the Department of Agriculture estimates 30 to 40 % of food ends up in landfills. It's both an environmental and economic problem, with food waste being one of the leading causes of greenhouse gas emissions.

A startup called Wasteless thinks machine learning can play a part in addressing the issue.

The company has developed an AI-powered system for automatically reducing the price of perishable food items as they spend more time on store shelves. The closer a product is to its best before date, the cheaper it will be to buy.

And you'll see all of that reflected in the price tags grocery stores have on their shelves.

A Spanish retailer ran a pilot with Wasteless which reported a nearly third less (32.7%) overall waste. Wasteless says its machine learning algorithms are developing all the time and are on track to hit an 80% reduction in food waste.
