I have been raising quails for past six months and wanted to figure out a way to recycle or repurpose quail poop. I checked if quail poop could be fed into biogas plant and and the answer is YES!. I went ahead and made a biogas plant.
General misconceptions about the biogas plant is ...will it smell?
No it doesn't. Its an airtight system. except while feed the plant and removing slurry, it doesn't smell at all.
It not dangerous if if you necessary precaution and it should work fine. Note that you need a specials burner for this gas. The link is given below if you would like to purchase it
