Disposable may be a dirty word when you’re trying to ease your burden on the planet, but when’s the last time you carried two dozen cups to the park for a BBQ or had 30 glasses on hand for hosting book club? The next time you're entertaining a giant group, go green and stay sane: Swap traditional plastic cups for Repurpose’s compostable version.

Traditional throw-away plastic cups are manufactured from petroleum—meaning they won’t biodegrade and will hang around landfills hundreds of years after you’ve polished off that glass of sangria. Repurpose’s eco cups are made from plants, are biodegradable, and compost completely in 90 days. “We’ve found they’re really popular on college campuses,” says Lauren Gropper, who co-founded the company. Beer-pong with an eco-conscious? That’s a game we can get behind.
