Brilliant recycling idea: crushed glass mulch into good wine
May 25, 2008
It all started with the idea that the sun reflecting off the glass mulch would produce better tasting grapes and better yields, so a pilot project was created to prove it.
Sandihurst director Hennie Bosman said he was ecstatic at the results because there was a noticeable improvement in the quality of the wine made from the trial batch.
“For me, it’s all in the tongue tip and the nose and there was a difference.”
Sift chief executive Linda Norris said nearly 14,000 tonnes of waste glass was produced in their area each year and most of that was sent to Auckland, China and India. However, it was becoming increasingly costly and uneconomic to send the glass out of the city and Sift wanted to find ways it could be used locally.
We hope the crushed glass will be commercialised for use in other vineyards, Ms Norris said.
