Some of you may have known that using things made of cardboard, such as fiber drums, shipping cardboard boxes, etc., is a good thing to do since cardboard is recyclable. However, it is a different case for a cardboard packaging that is contaminated with greasy food products, like pizza box. The oil stuck on the pizza box will actually ruin the whole recycling process since recycling paper products normally includes mixing the recycled items with water. And we all know water is never oil’s best friend. This only concludes one thing: greasy cardboard is not recyclable.
That leaves to a question: should we just throw away the pizza box as soon as we’re done eating the food?
We don’t necessarily have to. You see, it’s the part that is greasy that is unrecyclable. The rest is acceptable for recycling. So what we can do is to tear off the contaminated part, keep the clean one, collect these recyclable clean cardboard boxes and send them off to the recycling curb for further processing. Please don’t cheat by slipping one greasy cardboard into the piles as this will ruin the whole batch.
Have you recycled your pizza boxes today?
