Separation of PVC Bottles from Other Plastic Containers

In addition to chlorine intensity being affected by the distance from the detector, the intensity will also vary across the length of a bottle. Rgure 3.3 shows the x-ray detector 

J J Separation of HOPE Base Cups from PET Beverage Bottles 

The Center for Plastics Recycling Research (CPRR) at Rutgers University was conraiissioned to develop a process for the reclamation of soda bottles that could be widely demonstrated and transferred to the public to spur increased recycling in this area. This was done because there are a number of companies in the U.S. which recycle PET soda bottles, but their methods are generally proprietary and not licensed out. The Rutgers Beverage Bottle Reclamation Process (BBRP) is not meant to separate PET soda bottle colors or other type plastics, but rather to provide clean PET flake separated from caps, labels, base cups and adhesives. 

Because there are differences in the way PET beverage bottles are produced, it was necessary to determine the composition of soda bottles collected. The primary differences among bottles is the label materials used, cap material used, and whether a HDPE base cup is used. The average composition of PET soft drink bottle constituents are shown in Table 3.3. 

The process also Hovides clean polyolefrn flakes which are mainly the HDPE base cup and PP caps, and aluminum chips from caps. The process, a schematic of which is shown in 

32 Separation of PVC Bottles from Other Plastic Containers 

The separation of PVC bottles from other plastic in sorting programs has become important due to the adverse effects of even small amounts of PVC present in other plastic, such as PET. Upon being melted with PET, which is what PVC is most often mistaken to be, hydrochloric acid can form and corrode the metal parts used in plastic extrusion machines.
