Abstract
The aim of this work was to evaluate local conditions in Madagascar and their effects on anaerobic digestion process in order to select a
suitable technology and design for small-farm biogas production. Climatic conditions, input feedstock properties as well as limitations
and possibilities of commonly used designs for anaerobic digestion (AD) are discussed. Mesophile conditions in digester, co-digestion
of zebu dung with weed plants and agriculture residues and production of 1m3 of biogas per day were found as optimal regarding
local specifi cations. Common technologies used in developing countries are considered as inapplicable because of their need of large
amount of water for wet type of AD. Dry batch technology is recommended as suitable for the area in southwest Madagascar.
