Biogas Bag Installation Manual

This manual has been prepared to support practitioners with the installation of small bag digesters for the production of biogas. Together with its partners, FACT Foundation hasdeveloped a sturdy but low‐cost digester that can be easily installed by individuals with little or no background in biogas technology. It is intended for application in developing countries, in households or institutional setting. The digester bag is made from fibre‐reinforced PVC; it can be installed using materials that can usually be sourced in developing countries (e.g. PVC pipes, connectors, hose, valves).
A first batch of the digester bags was manufactured in November 2010; the first installation was implemented at the site of Mali Biocarburant in Koulikoro, Mali, in December. For a short video on the installation of the digester, please visit www.fact‐foundation.com.
