It’s more than a little ironic that surfing, an activity defined by being outdoors and in the ocean, can have such harmful ties to Mother Earth: the vast majority of surfboards are shaped from polyurethane foam and coated with a polyester resin, two components that don’t exactly make one with nature. But don’t let that stop you from taking to the waves—just be sure to surf the Internet before surfing the swells. Launched in 2007, Rerip.com helps you score a used board on the cheap à la Craigslist (the site lists sales for skating and snow gear as well), in addition to administering a tri-fold program for recycling boards. The Solana Beach-based company has two local drop-off sites for surfers to donate unwanted boards, which are either repaired and reused for surfing, repurposed for art, or recycled into concrete. “Even seasoned surfers don’t always think about the issue that surfboards are toxic objects, but we’re trying to inform that change,” says co-founder Lisa Carpenter. You’ve been informed, now make mother proud.
