Do Not Recycle
Unused paper napkins cannot be recycled because the fibers are too short to be made into new paper. Used paper napkins also cannot be recycled because they are usually soiled with food or grease, which contaminate the recycling process.
Ways to Reduce
Use Cloth Instead of Paper Napkins
Rather than use paper napkins, especially at home, buy a set of cloth napkins and use those instead. Linen napkins are more eco-friendly than cotton, but both are better than relying on single-use paper napkins.
