No, as the sign says - Not a Composter. And the Green Johanna is not - just - a composter.
Composting is a great way to deal with garden and vegetable based food waste and create a rich natural soil supplement for your garden. But it has its limitations as well as those advantages.

So, in terms of dealing with food waste, the Green Cone is a complete solution, the Green Johanna is a complete solution, and standard composting isn't. The Green Cone is also a heck of a lot easier to use. On the gardening side, the Green Cone doesn't replace composting, but it can work well in conjunction with it.
