OTIS Eco-Acetate frame is made from renewable resources widely present in nature. Derived from cotton seeds and plant matter, the acetate component of these frames is recyclable and biodegradable. 

Beyond that, OTIS use mineral glass lenses in 100% of the eyewear they manufacture. Mineral Glass is also sourced from natural elements like sand and soda ash, so they too are endlessly recyclable and environmentally friendly.
