Observations after first trials:

  1. Liquid is formed at the bottom of composter.
  2. Odor is formed strongly.
  3. When composter rotates, waste is not freely moving and mixing , it requires to push down.

 

 

Conclusions:

  1. No. of holes for air ventilation are not enough.
  2. Central pipe diameter is also too small results in choking waste in pipe.

 

Modifications done before Second Trial:-

  1. No. of holes on the circumference of buckets are increased.
  2. Central cylinder made of Dia. 175mm.
