Coffee brewing is in the midst of a revolution, and Im not talking about the AeroPress. It comes in the form of a small 2-by-2-inch single-serving pod that requires a special machine. Keurig, owned by Vermont-based Green Mountain Coffee, makes the most popular pods, called K-Cups. At the press of a button, the Keurig brewer punctures a small hole into the aluminum lid of an individual plastic cup filled with grounds, flushes it with steaming water, and, voila! Out comes one hot cup of joe.
But critics warn that the packaging needed for these systems comes with environmental and health-related costs. By making each pod so individualized, and so easy to dispose of, you must also exponentially increase the packagingpackaging that ultimately ends up in landfills.
