This will serve as a good example for future startups where taking one concept from one market does not always work in another market. Keurig managed to make a great product at an affordable price range, both the machines ($80-$250) and the K-Cups (~$0.85 per pod). However, a $400 machine, that just squeezes the pack for juice, and each juice pack running several dollars is enough to kill anyone's wallet. I liked how they made an attempt to promote a sustainable healthy lifestyle, but ultimately there are cheaper alternatives.
But how is it sustainable to grow fruit, pick it, wash and peel it, then cut it up and put it into some sort of disposable bag, then ship it to each individual who wants it, then require them to own an appliance that likely runs on fossil fuels to get the product out? They could have just shipped bottle of juice to the local supermarket and cut out the machine entirely. The waste would have been less because the bottles would have been recyclable, and they'd own the machines and use them in place in bulk. The shipping would be more sustainable because of the scale of doing all shipping to fewer grocery stores than all their customers (or at least all they hoped to reach eventually). The whole thing is wildly wasteful.
