Usach researchers develop technology incorporating recycled material in yogurt containers
Currently, dairy packaging waste made of high impact polystyrene (PS) is not recycled to produce new containers for the same product, because this material has a particular chemical composition that causes its strong deterioration with recycling, hindering its performance for producing new resistant and safe containers for safe food preservation.
PS is a hard-to-replace petrochemical polymer due to its low cost, light weight and impact resistance which prevents container breakage.
