With manufacturers placing more importance on minimising carbon footprint, most have attempted to significantly lightweight their PET containers. However this might not be the reality, says plastic packaging developer Plastic Technologies Incorporated (PTI).
Recycling polyethylene terephthalate pet plastics is not new, and most end up as non-food grade pet, such as in china where they are processed into textile fibres or other utility items. However, there is an increasing opportunity for the food and beverage industry to benefit from this too as food grade packaging materials can be made from recycled pet. One such method for this is through a bottle to bottle recycling process. By Dr Thomas Friedlaender, Krones AG
