Assistant: That’s an interesting question.  It turns out that the way coffee grounds decay depends a lot on whether or not they are exposed to oxygen.  So one way to lengthen the life of coffee grounds is to use oxygen-free glass jars, which won’t allow oxygen to interact with the grounds and cause them to decompose.

Assistant: It sounds like you’re asking about composting coffee grounds.  Composting is a simple process that is useful for turning coffee grounds, food scraps, and plant material into a nutrient-rich material that plants can use.  You’re right that coffee grounds don’t stay fresh indefinitely; coffee grounds can start to stink pretty quickly.  Composting is a great way to preserve the nutrients in coffee grounds before they start to stink.
