Putting tyre rubber in the road rather than on it is a multi-million-dollar opportunity for an Auckland recycling business.
Pacific Rubber takes tyres destined for the landfill and processes them into small granules for use in everything from sports turfs to road surfaces.
Co-founder Andrew Christie said the biggest market for recycled rubber was for use in roading projects. Rubber milled to the texture of black sand is blended into the top inch of the road to create rubberised asphalt concrete.
In the United States rubberised asphalt concrete, which has the added bonus of creating quieter roads, is the second largest single market for recycled rubber accounting for 12 million tyres a year.
Christie said Australian roading contractors were just beginning to use the product and the market was estimated to be worth around A$15 million ($19 million).
