Aha, the question of whether washing by hand or using a dishwasher is better! Another person on this thread made a good point about the amount of uses a ceramic plate needs in order to offset the carbon footprint of its production.

So, I suppose the real question is can we use a dishwasher enough times to offset the carbon footprint of its production? I would say yes, and if we can assume that a dishwasher loads is less intensive than the same load washed by hand, then the dishwasher is better in the long run.

But what do we do with the dishwasher when it's no longer usable?...
