#27 Recycling Plastic into Roads
After 844 trial tests, and setting his own street on fire,
founder of Scottish start-up MacRebur Toby McCartney finally hit on a viable
solution for repairing potholes. His idea sought to resurface roads using recycled
plastics, and the result is a form of polymer modification of asphalt that uses
a mixture of waste plastics and additives to create an alternative to bitumen. Bitumen
is the sticky, fossil fuel derived substance that binds together the aggregates
that surface our roads, and although Toby’s new business can’t eliminate it, it
can replace a proportion of it, lowering the road’s carbon footprint and
finding a practical use for waste plastics that are polluting our planet.
According to MacRebur this could be the start of a new type
of circular economy with local councils using local plastic waste to pave their
highways. Department for Transport trials are underway to assess the long-term
performance of the new recycled plastic roads.
