One of the early pioneers in the UK used chicken dung as the main feed for his biogas system. There are plenty of biogas systems in Bangladesh that use chicken dung. It helps to start the system with some cattle dung (it contains the right microbes), but you do not need more when it is working properly.<o:p></o:p></span></div></div><div><div style="margin-right: 0in; margin-left: 0in; font-size: 12pt; font-family: 'Times New Roman', serif; color: rgb(64, 0, 64); margin-top: 0in; margin-bottom: 0.0001pt; "><span style="font-size: 11pt; font-family: Verdana, sans-serif; "> <o:p></o:p></span></div></div><div><div style="margin-right: 0in; margin-left: 0in; font-size: 12pt; font-family: 'Times New Roman', serif; color: rgb(64, 0, 64); margin-top: 0in; margin-bottom: 0.0001pt; "><span style="font-size: 11pt; font-family: Verdana, sans-serif; ">The effluent that come from the plant is a very good fertiliser, is smell-free and does not attract flies. You could dry it, bag it and sell it. A bag digester will work, there are plenty of examples, but it will not last as long as masonry systems. There are some good biogas engineers in East Africa who can build these, but you need to look for them. If you have already ordered a plastic tube, you should start with that. Details of how to use it can be found at:<a href="http://www.adelaide.edu.au/biogas/poly_digester/" style="color: blue; text-decoration: underline; ">http://www.adelaide.edu.au/biogas/poly_digester/</a>.<o:p></o:p></span></div></div><div><div style="margin-right: 0in; margin-left: 0in; font-size: 12pt; font-family: 'Times New Roman', serif; color: rgb(64, 0, 64); margin-top: 0in; margin-bottom: 0.0001pt; "><span style="font-size: 11pt; font-family: Verdana, sans-serif; "> <o:p></o:p></span></div></div><div><div style="margin-right: 0in; margin-left: 0in; font-size: 12pt; font-family: 'Times New Roman', serif; color: rgb(64, 0, 64); margin-top: 0in; margin-bottom: 0.0001pt; "><span style="font-size: 11pt; font-family: Verdana, sans-serif; ">A 35 deg.C system is much easier to use than a 55 deg.C system. Kyle is a bit vague on temperature, it is better to run at close to 35 deg.C. However, it is very expensive to find a way to heat a digester, so most people run them at ambient temperature. The compost will be improved if it is left to mature. If it is fairly liquid when it comes from the plant, it can be absorbed into dry biomass (e.g. straw) and allowed to compost further. This will help kill pathogens and weed seeds. <o:p></o:p></span></div></div><div><div style="margin-right: 0in; margin-left: 0in; font-size: 12pt; font-family: 'Times New Roman', serif; color: rgb(64, 0, 64);

In Kenya we operate digesters at this temperature with no problem though 15˚C is too cold to start a digester we have found). Heating will just increase cost. If you want to get more gas out of the system, just get a larger bag digester. They are really cheap. Q energy in Uganda sells 300 meter cubed digesters for around $10,000. 150-300 meter cubed digester should be a good size for you.
