"Stretcho": Biodigester at Tamera Solar Village

Biodigester "Stretcho" is a IBC tank system that was built during the Solar CITIES Biogas Workshop at Tamera, Portugal in April 2015. As part of the Experimental Week, that took place in August 2015, the IBC tank was wrapped with two layers of stretch foil with an airspace in between to increase internal temperatures of the tank. The results are amazing! Two layers of stretch wrap increase the temperatures significantly and decrease internal temperature fluctuations caused by the daily high and low ambient temperatures.
