If you hear the words rubber roads a number of things come to mind. As a amateur racing driver, I think potentially more “grip”. There is a new phenomena taking place. The concept of recycled plastic containers and bottles being combed from our seas and waste dumps, to be converted and substituted for the bitumen that binds our road asphalt. India has been doing it since 2002, and the Netherlands is now actively pursuing it. We have also done some pilots in the UK. This is a brilliant example of recycling. Plastic materials have very long bio-degradation times, and it can take 450 years for a plastic bottle to fully degrade. Anything that can take plastic away from is a real is a real positive. Furthermore, by removing them from the sea and rivers we can further protect fragile marine life. Plastics have a high calorific value, and waste plastic has been considered as an alternative for fossil fuels, but of course this would increase COx. Re-utilising is also a powerful way to reduce landfill, and head to the UK goal of zero landfill by 2020. It also fits in with the framework of the new 6R sustainability system that goes beyond reduce, reuse, recycle to recover, redesign, and re-manufacture.

These are now being pioneered in the UK, and an enterprising company in Scotland has developed the plastic pellet blend that will bind the aggregate. The roads are are pothole free and more hard-wearing, which is solving 2 problems in one. Potholes are a massive issue on UK roads, and these plastic repairs are more robust. This is where Lean thinking is definitely helping sustainability.
