Watch A Waste-Reducing Community Fridge In Action

"A community fridge is a space where local people can exchange food," says Tessa Tricks, creative partner at UK-based environmental non-profit Hubbub. Food insecurity takes many forms, which is why it's called a community fridge rather than a food bank or pantry. The difference is that instead of relying on large donations of bulk supplies, the community fridge has a constant turnover of people giving and taking fresh food. Whether it's a glut of garden arugula at the end of the summer or a leftover portion of that evening's pasta you suspect nobody will finish, small donations to the fridge add up in a big way.

The town of Swadlincote in Derbyshire, England is a great example of how an everyday kitchen appliance placed in the right spot can positively affect your neighbors' lives while reducing your community's food waste. Check out a video of Hubbub's initiatives:
