Tesco & Asda have signed up to an initiative designed to reduce the amount of glass waste from the wine industry. Government-funded WRAP, said it would be working with British Glass to encourage more wine importers, brand owners & retailers to bulk import wine & bottle it in lighter glass bottles made in the UK. WRAP had already been working with Coors Brewers to bring to market a new lightweight 300ml Grolsch beer bottle that weighs 15% less than its predecessor. It will now be conducting a series of commercial trials involving wine that is sold at Tesco & Asda. The UK is the largest importer of wine in the world with over a billion litres imported each year, 80% of it already bottled, according to WRAP. By encouraging lightweighting, WRAP is aiming to reduce the amount of UK glass waste by 20,000 tonnes.
