The Green Johanna is the garden compost bin with a difference. A hot composter, the Green Johanna recycles all kinds of waste food – even cooked food, bones, meat and fish – into natural organic compost. Simply install the Green Johanna in a shady, sheltered spot and fuel with a few centimetres of garden waste. Then add two layers of food waste for every layer of garden waste. To ensure food waste recycling all year round, dress your Green Johanna in her winter jacket once the average outdoor temperature drops below 5°C consistently for a number of days.  As such, a winter jacket is often not required for the majority of the UK.

The Green Johanna is a top-performing hot composter that turns food waste - including cooked food, meat, fish and dairy - and garden waste into quality compost within months.
