New Zealand“s wine industry is requesting major changes to the way glass is recycled. Until two years ago, a plant in Onehunga recycled 98% of collected glass – melting it down and turning it into bottles again. But at present, after the takeover of recycling collections and introduction of large wheelie bins, many of the bottles collected are being crushed into roads, rather than being made into new bottles. Despite the use of larger collection bins, the recycling of glass back into bottles has decreased to 50% in Auckland. A bottle that is made from 100% recycled glass has about half the emission of a bottle that“s made from 100% raw material, a spokesman said. Moreover, recycling glass also uses less energy than using raw materials. However, much of the glass is being crushed into materials for roads or buildings, but not one bottle collected is made into another bottle. The glass used by a winery for its bottles is essential for its environmental reputation, and needs a high recycled glass content to keep its carbon emissions low. The wine industry has therefore requested the collection company involved to justify the mountain of glass it has stockpiled.
