[Digestion] Biogas from Begonia, Chrysanthemum and Poinsettia

[Anand Karve]

Dear Vianney,
the woody part of the waste which also includes the veins and midribs
of leaves, will remain as undigested residue in your biogas plant. You
would have to cut the biomass finely with the help of a device called
chaff cutter, which is used for shredding fodder before feeding it to
cattle. This device works very well for shredding plants before
feeding them into a biogas plant. Secondly, the digester must be
provided with a large drain valve near its base, with the help of
which you would remove the undigested debris from the digester.
Yours
A.D.Karve
