Woolworths has changed the packaging for its Own Brand sliced bread to bags made from 30% recycled plastic. Using advanced recycling technology (via the mass balance approach1), the bread bags’ recycled plastics have added to the tens of thousands of tonnes of virgin plastic Woolworths has removed from its supply chain. In-store bakery clam shells and lids that are made from 80% recycled plastic and are now recyclable. In the case of plastic packaging, mass balance refers to the proportion of material coming from processing recycled plastic versus that coming from virgin sources during the manufacturing process of plastics. This means you can’t trace how much recycled plastic makes its way physically into the packaging of each individual bread bag.
