A report on the production of carrier bags made from recycled rather than virgin polythene concluded that the use of recycled plastic resulted in the following environmental benefits:
* reduction of energy consumption by two-thirds
* production of only a third of the sulphur dioxide and half of the nitrous oxide
* reduction of water usage by nearly 90%
* reduction of carbon dioxide generation by two-and-a-half times
A different study concluded that 1.8 tonnes of oil are saved for every tonne of recycled polythene produced.
