Recycled glass is not only use to produce beautiful home decors, but also to hasten ripening of grapes. The wine industry is doing its bit to find new uses for recycled glass. Mostly meant to head for the landfills reaching a crisis in the South Island, glass recycling is being trialed as a ripening accelerant in one Canterbury vineyard.
Christchurch recycling firm TerraNova produces huge amount of waste glass, which is crushed into fine particles and spread beneath the vines ‘ and this helps reflecting light and heat onto the grapes.
The idea is generated from the use of mussel shells in other vineyards for the same purpose. The use of shells allowed better control of sugar levels ‘ then why not that be the case with the glass!
