This leads to non-uniform composting. Pathogen kill is non-uniform as thermophilic conditions develop only at the core. Process can be automated 9. Requires a lot of handling of garbage 10. Process can be continued during 11.
Process has to be stopped in monsoon.
No odour as the plant is completely 12. Lots of odour and bad smell, as covered and the composting process the process is carried out in open, is carried on at optimum level, at all under sub-optimal conditions of times. The power usage is very low. The total energy usage is high. Very useful in hilly regions and 15.
