Add scrunched up card egg boxes to compost bins/heaps as this will create air pockets and help with decomposition.
Use boxes for planting seeds. Plant out individual sections containing the seedlings and the card will rot away.
Cardboard egg boxes can be recycled with card. See CARD/CARDBOARD.
Buy eggs in cardboard packaging rather than expanded polystyrene as this material is not recyclable or compostable.
Please do not put into Paper Points. The cardboard fibres cannot be recycled into paper.
