Dear Tim
Well any size of biogas production is possible
from 250 l to 200 M3.Biodigestor of 5 Cubic meter is
the minium ECONOMIC size for a small familly
cooking gas consumption.
Composting lead to considerable loss of material
10 -20 porcent and hence a good combination of
integrated composting and ANEROBIC biodigestion(NO
LOSS) in a closed loop with water recycling ,liquid
biofertilizer,need to be studied.
If you dont think of recycling the natural
biomass residuos from animal , NATURAL BIODEGRADATION
WITH TIME making very significant amount of CO2 ,
methane gas, ALL going to atmosfere.The environment
impact will be very high if your animal production is
very high.Better you think of clean production with
environmentally friendly apropriate technology.We,in
the tropical region of north east of Brazil, RN state
, Natal city, do have a small young ecodesign team
WORKINg in this type of integrated biomass resource
INOVATIVE NOVEL technolgy for fuel, feed, fiber and
food production using biofuel FORM BIOMASS
WASTES(ANIMAL, AGRICULTURAL AND AGROINDUSTRIAL)
DETAILED STUDY NEED TO BE DONE FOR THE
INTEGRATED BIOGAS PROJECT, eventhough biogas digestor
can be simple,yet you may get very little return , if
not well designed and all resources are well utilized.
Feel free to consult here in this list forum your
project , before you put it in practice for operation.
Yours truely
