The Technology

Achieving consistent pathogen-free compost within a reasonable timeframe on a large scale requires an appropriately engineered solution.

The equipment should

• Provide sufficient oxygen for continuous aerobic degradation .
• Facilitate a sustained elevated temperature while maximising heat release to prevent overheating and ensure rapid conversion of putrescible waste to stable compost .
• Ensure that all material is sufficiently and evenly treated and that no short-circuiting or treated product contamination can occur .
• Contain all odours and potentially hazardous aerosols.

HotRot is an enclosed U-shaped vessel with a central tine bearing shaft.  The shaft is rotated periodically to maintain porosity and redistribute heat and moisture by mixing.

HotRot's unique rotating shaft, process control and other design features ensure efficient, fast composting.

Mixing
Redistributes heat and moisture ensuring even composting with no edge effects and no leachate 

Odourfree
Efficient composting results in low odour concentrations.  Control of airflow allows for an 'odourfree guarantee'.

Optimal particle size
Continual lofting of the material maintains good porosity, ensuring that better and faster composting of smaller particles is achieved.  Optimal particle size can be achieved via integration of shredders or chippers

Prevention of waste balling
HotRot's tines prevent balling and conglomerates forming.  Composting is achieved via both biological and physical erosion.

Modularity
This allows for flexibility in plant capacity and the ability to extend a plant by adding additional units. 

Continuous processing
Waste is processed continuously and inoculated by material already in the unit.  There is no need to wait for a pile to heat up or empty the entire vessel at any stage.  Composting is simpler and faster.

Safety
The self contained design means workers are not exposed to the composting atmosphere or moving machinery.
