Recycling is so much more than tossing out your empty kombucha bottle and separating your plastics from your paper products. And even if those things have become second nature in your regular routine, there are things we often overlook in the recycling process — like our makeup.   It's easy to rack up on loads of compacts, lipstick tubes, and foundation bottles, only to toss them in the trash when you're done. But more brands are trying to make your beauty routine more eco-conscious. For example, Seed Phytonutrients offers shower-friendly hair products made from recyclable material. Brands like Le Labo and L'Occitane offer refillable services at discounted prices, so customers can re-up on product without extra waste. And companies like TerraCycle work with beauty brands, like Garnier and Burt's Bees, to help recycle empty packages.   MAC Cosmetics also gives customers rewards for recycling. When you return six completely used containers to the MAC counter, you can walk away with free makeup. "Because we share your commitment to the environment, customers returning to a MAC counter or MAC Cosmetics online, you can receive a free MAC Cosmetics lipstick, or, lipgloss, or eyeshadow if you're part of the MAC Lovers program," a representative for the brand tells Refinery29. Qualified containers include blush compacts, eyeshadow pots, foundation bottles, lipstick tubes, and more. And once the products are returned to MAC through this program, they get recycled by the retailer.   So, instead of tossing that taupe shadow you just hit pan on or the Ruby Woo you've smeared to the last drop, save your empty tins. You'll be cutting back on the staggering cosmetic waste problem (have you heard of "dumpster diving"?), saving money on your next MAC purchase, and you'll be minimizing your carbon footprint.
