Abstract
This paper presents a review on different aspects
influencing the development of household anaerobic digesters.
Biogas technology has recently been considered as one of the few
most promising renewable and sustainable energies. However,
there exists certain challenges to household digester’s
dissemination. Some of these challenges are very critical to the
appreciation of anaerobic digestion processes as well as systems.
The type of waste, feeding regime, temperature, pressure,
retention time, hydrogen ion concentration and the carbon-tonitrogen
ratio are considered to be very important factors for
optimum anaerobic digestion processes. The plant sustainability
and the quality of anaerobic digestion bi-products are also
considered very important during design and implementation
stages.
