Until now glass has been crushed and put into landfill, but Fulton Hogan has been trialling a scheme since the beginning of the year at its Renwick crushing plant, where the glass is added in with the aggregate as it starts the crushing process.
The base course material has passed Transit New Zealand roading requirements, and more importantly, has been sold for use in roads, carparks and driveways.
Regulations allow for up to five percent glass material in base course for roading.
About 2000 cubic metres of the base course material has been processed, and a lot has been used in roading around Shakespeare Bay.
The marketing test means the project has been a success, and recycling of the glass into roading material will continue.
It also means people will not have to separate coloured glass at the Marlborough District Council's Wither Rd transfer station.
Fulton Hogan divisional civil contracting manager Wayne Barnett said a couple of people had specifically asked for the glass material because they wanted to support the recycling initiative.
