Reuse. Regrow. Reimagine.

SEE GRASS CLOSED-LOOP SYSTEM* RECYCLED PLASTIC + GRASS FIBER + BIO GAS = SUNGLASSES REIMAGINED.

Zeal Optics See Grass frames combine 10% recycled plastics and 30% grass fibers, produced in a closed-loop system. This fibrous base is combined with recycled plastics to reuse waste material and keep it out of landfills. See Grass allows us to create beautiful, durable sunglass frames, each of which is unique, while finding alternative uses for what was previously considered trash and byproducts.*See Grass is produced at a closed-loop German biorefinery where the fibrous grasses are grown and mixed with pre-consumer recycled plastics from healthcare, pharmaceutical and cosmetic applications. The process is powered by a methane turbine that runs on decomposing organic matterand, in turn, creates fertilizer to grow the grasses, without generating any wastewater or byproducts.
