Eh - there is actually plenty of room for pretty much all the trash humanity could possibly create. A hole ten miles square and couple of hundred feet deep could hold all of the U.S.'s trash for the next 100 years (this is not a controversial statement). And recycling is energy inefficient for pretty much everything but aluminum and steel.

Keurig solved a huge problem in offices - how to always have coffee available when people en masse are pretty bad at refilling the coffee. No amount of hand wringing will make people better at things like refilling coffee.
