Bottle-to-bottle recycling

Over the last years, PET bottle-to-bottle recycling increased highly over the last years.

Today, many technology suppliers provide recycling machinery able to produce food contact approved rPET. Sophisticated decontamination processes allow decontamination levels of virgin PET.

A market survey gives an overview of global suppliers of bottle-to-bottle recycling plants for food grade PET in the scope of bottle-to-flakes, flakes-to-granulate and bottle-to granulate processes. Some of the suppliers offer the complete scope.
