Lots of things. Like composting for example. In fact, nothing irks me more than seeing people toss their coffee grounds into the trash can. Did you know that around 12% of the waste stream going to landfills is food waste? Reusing coffee grounds is a good way to knock that number down, and that’s good for us and the environment.

Coffee grounds are perfectly easy to reuse, and I discuss a few ways in my coffee column this week on The Kitchn. Consider it your guide to zero waste coffee consumption.
