Glass container manufacturer Rockware Glass has produced what it is calling the UK's first-ever 70cl spirit bottle made with less than 300g of glass. The new bottle, weighing in at 298g, is now available for Rockware's customers to purchase, & with less glass means less waste would be produced once the bottles are used. According to Rockware marketing communications manager Simon Morgan, the new bottles could be on supermarket shelves in 2007. Rockware believes it is the first bottle of its kind in the UK, although it said that there was a company in Japan working on a similar product. Rockware has spent the last 18 months designing the bottle in collaboration with WRAP as well as retailers & bottle fillers. The company say the bottles are as sturdy & as aesthetic as heavier ones.Lightweighting has been achieved by altering the distribution of the glass.
