“Sao Paulo” is one of the two biodigesters that were built during the Experimental Week at Tamera Solar Village in August of 2015. The system was inspired by Solar CITIES’ 3 IBC tank system in Sao Paulo. At this site, we modified the dual-gas holder system to avoid the use of a water pump. Instead, pressure is created by feeding the fertilizer and gas pipe. These pipes are as high as the the water displacement tank which is on top of the gas storage tank. The digester itself is insulated with straw bales and coated with a light straw mixture.
