Lidl, Tesco, Waitrose, Greggs, Morrisons, M&S, and Asda have switched to Greiner Packaging UK & Ireland’s K3 r100 self-separating packaging for their own-brand instant porridge pots, aiming to increase recycling efficiency across waste management systems.An evolution of the original K3 cardboard-plastic cup, K3 r100 is designed to enhance recyclability by allowing materials to separate automatically before reaching near-infrared (NIR) detection at recycling facilities. Greiner Packaging says the integration of NIR technology ensures proper material detection and sorting, with cardboard and plastic correctly assigned to their respective recycling streams.
