Off the coast of Catalonia, an intriguing experiment in the circular economy is taking place. Dozens of fishing vessels are heading out to sea and bringing back tonnes of plastic waste alongside their usual haul. About 10kg of waste is collected for each pair of glasses it sells. Sea2see separates what it can use for the glasses and the rest is sold off to other companies for use in different processes such as manufacturing nylon thread. The plastic is then used as the raw material to make recycled designer sunglasses for Barcelona-based company, Sea2see. Thanks to agreements with 22 Catalonian port authorities, the company helps fishermen across the region bring in around a tonne of plastic waste every three days.
