[Digestion] Biogas at Flower Farms

[Anand Karve]

Dear Vianney,
any type of green plant waste can be converted into biogas. The lignin
in the biomass would keep accumulating in the digester. You would have
to provide the digester with a drain valve near the bottom, which
would be opened once every 3 months. When you open the drain cock and
allow some of the fluid to drain out, the accumulated debris would
also flow out of the digester along with the water.
Yours
A.D.Karve
