Environmental Impact
Glass retains its colour on recycling, and the United Kingdom has a large surplus of green glass because it imports a large quantity of wine but produces very little. 1.4 million tonnes are sent to landfill annually.
Glass is a relatively heavy packing material and wine bottles use quite thick glass, so the tare weight of a full wine bottle is a relatively high proportion of its gross weight. The average weight of an empty 75 cl wine bottle is 500 g (and can range from 300 to 900 g), which makes the glass 40% of the total weight of the full bottle. This has led to suggestions that wine should be exported in bulk from producer regions and bottled close to the market. This would reduce the cost of transportation and its carbon footprint, and provide a local market for recycled green glass. Less radically, box wine is sold in large-size light cardboard and foil containers, though its use has been restricted to cheaper products in the past and as such retains a stigma. Some wine producers are exploring more alternative packagings such as plastic bottles and tetra packs.

Famous quotes containing the word impact:
“One can describe a landscape in many different words and sentences, but one would not normally cut up a picture of a landscape and rearrange it in different patterns in order to describe it in different ways. Because a photograph is not composed of discrete units strung out in a linear row of meaningful pieces, we do not understand it by looking at one element after another in a set sequence. The photograph is understood in one act of seeing; it is perceived in a gestalt.”
