Paper towel is an absorbent, disposable towel made from used paper and is used for cleaning, wiping liquids and greases around the house.
Why is it not recyclable?
Paper towel's fibres are weak and are not suitable for recycling, like toilet paper.
They cannot be mixed with other clean recyclable items to increase their recyclability.
Compost it, if you did not use it for harmful chemicals or anything that cannot go into your compost.
Throw it in the non-recyclable bin, if what you wiped with it can also be safely discarded in the bin (such as hazardous liquids).
