In an ideal world of circularity, nothing would be waste.

All products would be taken back by their manufacturer and be recycled to produce more of the same - they would all be made of recycled materials and be 100% recyclable. Consumer products would have carbon-neutral footprints and those of the companies making them would be negative. All raw materials would be responsibly sourced and all plastics would have been replaced with bio-based alternatives. Manufacturers would mine metals from landfill and extract plastics from the ocean to undo the damage we have caused.
