Instead of throwing them in the trash or down the garbage disposal, compost used tea bags and coffee grounds. Most people start the day with some sort of coffee or tea. Hopefully you make that at home to save both money and the environment. Take those grounds or tea and put it in your compost bin. (If you don’t have a compost bin, you may want to check out this post that includes an award winning video of our children teaching people how to compost.) Because the tea leaves and coffee grounds are already ground up they turn into compost very quickly.
