Before we could mold the plastic into its new form to become a product (The Ocean Cleanup Sunglasses), it required a small but necessary amount of additives, such as stabilizers and pigment. These additives allow the material to achieve the performance and technical characteristics required for manufacturing while at the same time create a beautiful, ocean-inspired aesthetic for the product. The metal in the frames was added for more stability, good display and readability of the logo and the QR code.
