Observations after first trials:
- Liquid is formed at the bottom of composter.
- Odor is formed strongly.
- When composter rotates, waste is not freely moving and mixing , it requires to push down.
Conclusions:
- No. of holes for air ventilation are not enough.
- Central pipe diameter is also too small results in choking waste in pipe.
Modifications done before Second Trial:-
- No. of holes on the circumference of buckets are increased.
- Central cylinder made of Dia. 175mm.
