[Digestion] A D Karve_pl send your case study regading AD study

[Anand Karve]

Dear Kiran,

The biogas producing organisms live in the intestines of animals. Therefore
they eat what the animals eat. You use dung only as a source of the
organisms at the beginning, after you have constructed a biogas plant.
Later on you use only food waste as the feedstock. Dung is not required at
all.

Yours A.D.Karve
