Recycling & granulators | machinery feature


Recycling is of growing importance. We highlight some of the latest techniques, which were seen at the recent K2013 exhibition


Sorting out recycling


Visitors to K2013 discovered new ways to sort and recycle plastics waste, including a method to remove adhesive labels and another to recycle bioplastics. Bühler used the show to launch its Optical Sorting


Station (OSS), which integrates all the necessary elements – including plant engineering, sorting technology, pneumatic conveyors, pre-conditioners and ancillary equipment. “This will mean that processors no longer need to


source separate elements from multiple suppliers, and manage multiple relationships,” said the company. For fl ake processing, an optical sorting station


features a purifying, refi ning, sizing and grading stage which can include one or more Sortex optical sorters. These are linked together, convey the product between stages and can re-introduce it into the system for re-sorting.

collected at the other end – ready for bagging or further processing.


Charith Gunawardena, head of optical sorting at


Bühler, said: “We want to help our customers achieve the most effi cient sorting methods on plastic fl ake processing lines. We have already installed the full optical sorting station for several of our plastics customers, including Deceuninck and ITW Poly Recycling. These companies are beginning to see increased effi ciency and yield from their processing lines, which leads to higher operating profi ts.”
