Decentralized anaerobic digestion is a promising technology to handle the large organic fraction of the municipal solid waste (e.g. kitchen waste) with the additional benefit of producing biogas as well as fertilizer. This paper evaluates the suitability of the ARTI Compact biogas system as a decentralised low-tech treatment option for the organic fraction of household waste in Dar es Salaam, Tanzania.

Some possible improvements are briefly discussed, such as the use of certain comparatively clean sludge fractions and use of two-stage technology for the recovery.
