The recyclability issue is discussed in the eastbayexpress article linked by anigbrowl in reply to one of the sibling comments.

Coffee companies are well aware of the problem. The second brewing system Keurig introduced, the Vue system, tried to address the issue of recyclability in what the company called "an incremental step on our environmental journey." The system doesn't work with the original K-Cup packs, which are made from number seven plastic, a blended plastic that's nearly impossible to recycle. Instead, the Vue capsules use a plastic cup made from polypropylene, number five plastic, and users can peel the foil lid and filter away from the cup.

The cups are then recyclable — in theory. The problem is the cups are too small to be captured in most recycling facilities where machinery separates objects by size and density, said Mark Oldfield, assistant director of public affairs for California's Department of Resources Recycling and Recovery. Most facilities filter out items under two-inches in diameter. In any case, number five plastic is rarely recycled in California, Oldfield said. "It's very difficult to deal with something like that," he added. "It's something where convenience is trumping our typical mantra of reducing and recycling."

After reading halfway thru the article, I was reminded about Compostable K Cups. These are a paper lid, cardboard ring, and paper mesh, without the plastic cup cover.
