The natural corks that stop most wine bottles around the globe are truly things of beauty. The material is very hard to come by—a cork tree must be growing for 25 years before it’s mature enough to harvest, and that harvest can only happen once a decade. Most of the corks that are removed from bottles every year end up in landfills, even though cork can be recycled easily, and used in hundreds of eco-friendly applications. In 2008, though, America’s largest natural cork producer, Amorin, launched Re-Cork, a bold effort to salvage used or unusable corks. To find a collection spot near you, visit RECORK.org. Or, if no one in your neck of the woods has a donation spot, collect 15 pounds of cork and ship it to the organization, free-of-charge.
