Since 2005, PET producers have made considerable efforts to improve the efficiency of PET resin manufacturing and have succeeded in significantly reducing its environmental impacts.
In particular, production of Purified Terephthalic Acid (PTA) has benefited from major technological upgrades, while the efficiency of the polycondensation step (PET production) has also been optimized.
Nestlé Waters utilizes the international database from Plastic Europe to assess the environmental impacts of PET. In April 2010, a new eco-profile study of PET was consolidated with data provided by major European PET and PTA producers.
The report confirmed noteworthy changes in the environmental performance of producing 1kg of primary uncompounded PET resin.
The updated figures are shown in the following schema :
As PET bottles represented three quarters of our 2010 production, such an improvement in PET production process has been one of the major contributors.
