Researchers at the University of Alicante have developed a procedure that removes printed ink on plastic films used in flexible packaging getting a product free from ink and suitable for recycling. This new technology developed and patented by the UA Waste, Pyrolysis and Combustion Research Group, allows the removal of printed ink through a physical-chemical treatment and retrieves the plastic film clean, increasing the added value of the recycled product, plus pigments obtained can be used in other applications.
