Carbon cost of recycling PET drops at AWS
July 16, 2010
A study into the carbon penalty of recycling PET by AWS Eco Plastics has shown that it is substantially less than that of producing virgin PET, and getting lower.
AWS says that the study was carried out at its Hemswell plant over the past six months and showed that the carbon cost of producing its purePET 78 food grade rPET pellet is 254 kg/tonne compared to the carbon cost of producing virgin PET, which stands at 681 kg/tonne, having only recently been revised down from 927 kg/tonne.
AWS says these figures will improve further during 2011 to 213 kg/tonne, as the plant reaches its full capacity and enjoys the associated economies of scale. Based the current agreement to supply Artenius PET Packaging Europe with 13,000 tonnes of purePET 78 annually, AWS says it will be achieving a carbon saving during 2011, of 6,084 tonnes.
