Are coffee grounds compostable?

QUESTION: Are coffee grounds compostable? And what about the filters? -Rick G

ANSWER: Coffee grounds can be added to compost and are a great source of nitrogen, once broken down. Adding coffee grounds can also help increase the moisture content in your compost pile. Used coffee filters can also be added to the compost mix, because limited amounts of paper also break down over time. Keep in mind when adding coffee grounds to your compost that, even though they are brown in color, coffee grounds are considered green compost material that are rich in nitrogen, and will need to be balanced with some sort of brown compost material that is rich in carbon. If you use K-cups for making coffee, you can open up the cups and empty the grounds into your composter before you throw the cup out.
