 GreenBottle has an estimated 10% of the carbon footprint of glass and weighs just one sixth of an average wine glass bottle, making it much more fuel efficient to transport both in bulk and for consumers.Glass is often regarded as a green form of packaging but its production process is highly energy intensive and whilst 62% of glass is recycled in the UK, only 50% of this is remelted.The balance is either destined for land fill, road aggregate or fibreglass insulation manufacture.
