Circular11 turns low-grade plastic waste into building materials and home products, in order to create an end-market for the contaminated and film-based plastics that make up between 50 and 80% of global packaging waste. Especially in emerging markets, most of this is openly burnt or leaked into the ocean. We use composite and biocomposite technology to valorise this waste, creating locally useful products that can be recycled again and again, and thereby making closed-loop, local circular economies that are accessible to communities anywhere in the world.
