Although kitchen towel and napkins do break down in landfill, low-waste lifestyles are about avoiding all unnecessary landfill! Many coloured ones also contain chemical dyes that are toxic for the environment. Consider going back to fabric napkins for your dinner times, and use cloths and tea towels to wipe up spillages. To avoid bacteria spreading, cut up some old tea towels or other cloth and keep them in a jar. Once you've used them, pop them in the washing machine!
If you prefer a more aesthetic look in your kitchen and don't mind investing a little more into a product, consider reusable kitchen rolls! You can use them just like ordinary kitchen roll, but instead of throwing them away when you are done, you wash them and reuse! If you are particularly crafty and/or have access to a sewing machine, you can also make these yourself.
