Birds Eyewear puts people and the planet at its core. The frames are made with sustainable materials, which are never derived from or exploit animals, establishing a sustainable and ethical manufacturing process. Materials include certified woods, bio-based acetate, renewable cork and recycled aluminum. Bio-based acetate is fully bio-degradable. Furthermore, all dyes used in the frames and cases are plant-based. Each pair of Birds gives back by working to distribute solar light to families in Zambia and Malawi. Overall, the brand supports circularity in its operations by designing frames that are built to last using ethical labor, are recyclable or repairable, and pairs of frames are reused. They offer a recycling program to take back preloved frames, and will give you a discount on your next pair of Birds when you send them in. All packaging is also recyclable and biodegradable. The brand aims to be carbon negative by 2025.
