Sustainability must be fully incorporated into material design

To the general public, the plastic problem is all about disposable single-use packaging. We are exhorted to use fewer plastic carrier bags, and products are sold as eco-friendly on the basis that they are packaged in paper, glass or steel – a sometimes questionable claim. But it’s essential to realise that demonising polymers and plastics is not the solution. They are more than simply packaging.
