Members of the UK bottled water association, the Natural Hydration Council (NHC), have reduced the amount of plastic in their bottles by an average of 12% since 2008. In a recent survey conducted by the NHC, its members revealed that they all have been making significant strides in light weighting, with a particular trend in reducing the amount of Polyethylene Terephthalate (PET).
Other areas NHC members have highlighted include secondary packaging, transportation and the increasing use of recycled PET (rPET) for primary packaging.
Bottled water is the lowest impact packaged drink in the soft drinks sector, whether judged by its carbon footprint or its water footprint, since there are no agricultural water inputs and limited water processing inputs. In the manufacturing stages, on average only an estimated 0.53 litres of water is needed to produce a litre bottle of water.
