HOTBIN is an aerobic compost bin. It relies on the composting bacteria having access to an oxygen supply in order for them to survive and work efficiently.
The addition of Bulking Agent assists airflow within the unit and helps to eliminate the need for turning or rotating your waste. When added to the bin, the structure of the bulking agent's woody particles create lots of little air pockets which allows air to circulate through your HOTBIN.
As a rough guide, generally a 75ltr bag will last approx 6 months. (consumption will vary user by user)
