Proposal titlePRODUCTION OF EASILY RECYCLABLE CO-EXTRUDED SHEETS BASED IN THE

USE OF A RENEWABLE BIOPOLYMER AS INNER LAYER

AbstractComplex co-extrusions offer good barrier properties against water vapour, gasesand

aromas, together with outstanding mechanical properties. During extrusion andvacuum

forming a lot of waste is produced. For several years now the SME proposershave been

looking at different technical solutions to efficiently separate thedifferent co-extruded

layers in order to recover and thus reuse valuable polymers,such as polystyrene. The

proposed RTD work will focus on the production of easilyrecyclable co-extruded sheets

based in the use of a renewable biopolymer as innerlayer. The use of a biopolymer as inner

layer in the food container sheets, canselectively facilitate the adhesion of layers - by

dissolving it in hot water, forinstance. A broad range of separation techniques is then

available to separate thedifferent layers. In this way, fabrication losses can directly be

recycled and reprocessed internally leading to a reduction in waste (up to 40 %).
