Until then, a much cheaper way of hot composting for those who never heard about it.

One hot composting method, the Berkeley method, developed by the University of California, Berkley, is a fast, efficient, high-temperature, composting technique which will produce high quality compost in 18 days.

The requirements for hot composting using the Berkley method are as follows:

Compost temperature is maintained between 55-65 degrees Celsius
The C:N (carbon:nitrogen) balance in the composting materials is approximately 25-30:1
The compost heap needs to be roughly 1.5m high
If composting material is high in carbon, such as tree branches, they need to be broken up, such as with a mulcher
Compost is turned from outside to inside and vice versa to mix it thoroughly.

With the 18 day Berkley method, the procedure is quite straightforward:

Build compost heap
4days – no turning
Then turn every 2nd day for 14 days
