 Plastic bottles require up to 4.5 times the amount carbon to produce compared to a milk GreenBottle.Most plastic, even if it has been recycled several times, is eventually bound for landfill where it persists indefinitely.In 2010, there were warnings that the UK had just eight years of landfill remaining  and the EU Landfill Directive legally binds the UK to reduce its municipal waste, by 2020, to 35% of 1995 dumping levels.
