[Digestion] Feedstock about ARTI compact biogas digester

[Han Haitao]

Dear all,

Recently I noticed the feedstock of ARTI compact biogas digester is mainly
organic material like food waste, damaged grains and etc.
the ARTI compact biogas digester would generally  require about 1 kilograms
of dry materials per day, I think that's a large amount.
Rural families don't have so much food waste. Even If they do have some, it
will be used to feed pigs and chickens.
Maybe Urban families have much food waste,  and they don't have animals to
feed.
