PTI has developed the PET Packaging Recycling Calculator app so that users can see how the material, barrier, additive, closure, labels, etc. decisions they make can potentially impact the next generation of PET (rPET) that is produced from these recycled containers. The calculator has been designed as a screening tool that can help users determine whether or not they should consider more in-depth testing.
The free download can be quickly located in the iTunes App Store or Google Play (formerly the Android Market) by searching for “Recycle Calc” and looking for an icon with the familiar PETE resin identification logo.
Users select the PET resin type from listed options, indicate if the package is multilayer, indicate whether or not additives, coatings or labels have been used, does the label release in a hot caustic wash, do inks bleed or transfer onto the PET during the wash, does the container have a closure, seal, other attachments, and do they float in water.
Users are then taken to a summary screen where they have the opportunity to modify any of their previous answers. When they are finished, they press the submit button which takes them to a conclusions screen. Answers fall into one of three categories: recycle guidelines appear to be met; some components appear to be problematic for recycling; or the package appears to be problematic for recycling.
