New Zealand beer company DB Breweries has installed bottle crushing machines that turn their DB Export Beer bottles into usable sand for construction and even pharmaceuticals. This saves the extra step of sending the empty bottles to be processed in a recycling centre.
Simply drop in your used beer bottle and the machine turns it into 200 grams of powder. The process of turning glass bottles into sand involves the removal of silica dust, which results in the sand substitute. It accounts for 2 tonnes of total sand substitute ever year in New Zealand.

Beach sand has been heavily used in construction for decades and with the increase in demand, it’s causing 70% to 90% of our beaches eroding. Two-thirds of New Zealand’s glass already go back to glass manufacturing but this project is helping make the remainder useful again.
This project aims to replace the sand with beer bottle sand, which will not only preserve our beaches but also prevent the glass bottles ending up in landfills. This project is helping to increase the recycling rate for consumer glass and making it useful for construction and roading.
