Recycled polyethylene terephthalate RPET

As PET is nonbiodegradable, recycling is an appropriate use of the resource. PET bottles have been recycled since the 1970s (Awajaa and Pavelb, 2005). However, the quality of the resulting recycled polyethylene terephthalate (RPET) depends on whether the bottles to be recycled contain contaminants including dust, colouring, acids and water (Awajaa and Pavelb, 2005). 

In the Master s dissertation entitled Effect of natural and accelerated ageing on the properties of PET/PC (80/20) blend , recycled polyethylene terephthalate (rPET) was blended with PC (80/20 wt/wt), and then submitted to natural ageing in the city of Rio de Janeiro [17]. For comparison purposes, we also monitored the accelerated ageing of the blend in an appropriate chamber under the same conditions, 2,000 h of exposure were performed. The Fourier-Transform infrared spectroscopy revealed the tendency of the PET and PC carbonyl indices to decrease upon an increase in... 

Fibre was the original outlet for recycled polyethylene terephthalate (rPET) and it still consumes a very large tonnage. In 2001, 144,000 tonnes of rPET (62% of all European supply) were used in fibre applications whereas in 2008, 363,000 tonnes of rPET (45% of all European supply) were used in fibre production. Early uses of...
