Dear Jeff, the flesh of the pumpkin consists of sugars and starch. The seeds are also digestible, having starch, protein and fats. So pumpkins should work as feedstock for generating biogas. You may have to shred it or pulp it. Before using anything as feedstock, one should ask a simple question, "would an animal eat it ?".If the answer is "yes", one can use it as feedstock. Bones are an exception. About two years ago, I helped a building contractor friend of mine in Montana State constructing a biogas plant having a digester of 5000 litres. We used two plastic water tanks, purchased from a local building material shop. It was an indoor biogas plant. My friend put a hot water pipe at the base of the digester. It was bent in a circle and it was connected to the hot water system of the household. It is still working, even in winter. It is however not in regular use but serves only as a demonstration.
