People are being reminded about the knock-on effect of putting greasy pizza boxes out with their recycling on National Pizza Day, February 9, as although pizza boxes can be recycled since they are made of cardboard, this is only true for pizza boxes that haven’t been contaminated with excess grease and leftover food.
Research conducted by Barratt Homes revealed that one in four people are unaware that cardboard can be recycled. The answer to “can pizza boxes be recycled?” comes down to what condition the cardboard is in before being added to your recycling.
When pizza boxes contain too much grease on them, this makes it near impossible for the cardboard to be recycled into new products. This is because oil is harder to remove during the recycling process and results in reducing the quality of the recycled material.
