food waste

Americans throw away about a third of our available food.

But what some see as trash, others are seeing as a business opportunity. A new facility known as the Heartland Biogas Project is taking wasted food from Colorado's most populous areas and turning it into electricity. Through a technology known as anaerobic digestion, spoiled milk, old pet food and vats of grease combine with helpful bacteria in massive tanks to generate gas.

Gleaning is an ancient word for a practice that dates back to Biblical times. Farmers allowed peasants to take leftover crops after the harvest was over. The practice has been making a comeback in recent years as a way to fight hunger locally and cut back on food waste. 

At Clean Greens Farm in Duvall, Washington, a field of kale is overflowing. It's been picked before, but it just keeps on coming, says farm manager Tommie Willis, as he leads a group of volunteers to one patch and shows them how to glean.

Imagine your weekly grocery trip. You come home with four bags, but instead of putting it all away, you throw out one full bag of food.

That’s effectively what the average American household disposes of each week.  And the habit is costing us money, and maybe even our sanity.
