Road Science united with Kiwi beer brand DB Export in its latest recycling effort - using bottles to make a man-made sand - an effort the companies hopes will help preserve our beaches.
New Zealanders use sand to make roads, pathways and pipelines, even build homes - and sourcing it from our coastlines is causing erosion, damaging ecosystems and marine life habitats.
The average Kiwi consumer uses more than 200kg of sand each year, most of which comes from beaches. It's a non-renewable resource and is also used to make glass.
Every year 27 per cent of glass waste makes its way into New Zealand landfills.
Through its recycling initiative DB Export aims to convert its used bottles to 100 tonnes of sand substitute. That's equal to about 500,000 beer bottles.
The company hopes the programme will help cut down the amount of sand dredged from beaches.
