The Green Johanna "hot" composter will compost two parts cooked or uncooked food waste (including meat, fish, bones, dairy products, vegetables and fruit) to one part garden waste and produces a rich compost all year round. Its clever design means that micro organisms, bugs and worms together with oxygen work together to create temperatures of 65°C (150°F). You can add a winter jacket to your composter that will maintain these temperatures in the colder winter months, the jacket made from foam polyethylene should only be fitted when the average out door temperature consistently falls below 5°C, and removed when the temperature is constantly above 10°C. It is essential that the winter jacket is removable during the process otherwise the compost will burn, in which event the micro-organisms die and the process is halted.
