Don't be alarmed if you find Greenfill and his friends in your package. They may look like polystyrene but are in fact made from GM-FREE STARCH making them 100% BIODEGRABLE.
To dispose of Fill and his friends run them under warm water in your sink. Fill and his friends will gently dissolve away as they are made from maize starch which has been extruded using heat and high pressure.
Alternatively, as Fill and his friend conform to EN13432, they can go on an adventure courtesy of your food waste bin, or on your compost heap if you have one.
Or keep hold of them to use again when packing delicate items.
