A large range of sustainable phone cases have come onto the market in the past year, but how can you know which are best—and which are genuinely eco-friendly? We’ve rated the best sustainable phone cases, looking for cases that are biodegradable, stylish, durable, and ergonomic. Here are some of the top cases for your phone, giving you plenty of choices for a product that will look after both your phone and the planet. It’s durable enough to protect your phone outdoors or when hiking or playing sports, but it’s also perfect for daily use. We’d like to see the color range expanded to provide more than a handful of subdued choices, but it’s otherwise one of the top sustainable phone cases on the market today. The Pela design is slim, easy to grip, and durable. Their cases are made from a material called Flaxstic, composed of flax straw shive and plant-based biopolymers. It also meets government standards for compostability and is free from unwanted chemicals frequently found in plastics, such as BPA and phthalates. With plenty of cool designs and gorgeous colors, you can shop with pride that a portion of your purchase will go to charity, and your phone case is helping the environment. However, we recommend going for a darker-colored case, as some users report that the paler colors tend to stain easily. The case is slim and fits snugly onto your Pixel, keeping it safe, thanks to a drop-proof rating of up to two meters. It’s also QI compatible for wireless charging and it’s easy to take it on and off. Currently, there are only two color choices for the Pixel, a black and sea urchin purple. It’s also slightly more expensive than other brands, but this case will appeal to anyone looking to raise awareness of plastic pollution in our oceans, an important issue worldwide. The cases themselves are made from a combination of bamboo, cornstarch, and pellet, all organic materials that will break down 100% within a few months after it’s discarded. Even the laser used to customize the cases is free from chemicals and toxins, so you can be confident that your purchase is helping the environment. Plus, the packaging is made from recycled materials. The Custom Compostable will keep your phone secure too, with a drop rating of up to four feet and a one-piece, slim design that you can pop on and off. Bamboo is known for its strength, so it’s a natural choice to include in a phone case. If you’re looking for a versatile case that can match your style, the Casetify Custom Compostable is a great choice, if your budget allows. The Bottle Case 2 is comfortable to grip, thanks to the slightly textured feel of the fabric. Its hard shell design slips firmly onto your iPhone, guarding against scratches and drops. We also like that the case is water-resistant, if you plan on taking your phone near the pool or beach. Plus, the case allows for wireless charging. If you’re the type who enjoys using your phone as a wallet case, the Bottle Case 2 offers an exterior cardholder that can fit a card and ID. Just note that you’ll need to take the cards out to use the case with a wireless charger. It’s a great contender for your next iPhone case, available in a range of colors inspired by nature. It’s also compatible with wireless charging and offers a raised bezel around your phone’s camera and screen, keeping it protected when your phone is placed facedown. A one year warranty is also included with purchase. The neutral color palette aligns with Organicore’s environmentally-friendly ethos, but note that, like some of the other cases above, light cases may show dirt or stains over time, which can be hard to remove. Polycarbonate is both strong and recyclable, so it’s a useful material to use for a clear phone case. There are a few other notable features found in the Disc though—first, we like that it’s treated with permanent antimicrobial protection, as everyone knows how dirty phone cases can get. It’s also scratch-resistant and treated with UV light to prevent the case from yellowing over time. Your iPhone is protected from drops up to six feet. However, note that this case does tend to show fingerprints. With any Disc purchase, you get a free shipping label to post them any unwanted CDs for recycling. The Disc is probably the best clear, hardshell case on the market if you’re looking for a sustainable product.
