Have I got this right? I pay $0/m, I chuck my food scraps in the garbage. OR I pay $33/m, I fart around with some device in my kitchen, then send them by post to some company and get nothing in return. And from an environment point of view, it is a device that needs high energy to produce. I actually compost. It cost say $33 one off for the bin, which sits on soil, and can take probably couple years worth of waste. I am not in an appartment, but surely the solution there is a compost on common outdoor or rooftop area, where the cost is lower because it can be shared.
