The Green Johanna™ compost bin is different from a standard compost bin because it is designed to be rodent proof and is well insulated. This means that the composting process is quicker than in a standard compost bin and you can put in all types of food waste, including cooked food, bones, fish and meat, which should not be added to a standard compost bin.

The Green Johanna is offered with an aerator and winter jacket (optional) which can be used to accelerate the composting process.
