vi.Lack or poor post-installation support.

Post-installation support for biogas systems has lagged demand because of a dearth of qualified experts and competent artisans. Service typically stops at the end of the "12-month guarantee period" after installation that is sometimes advertized. The farmers and operators are technologically illiterate, so they have no idea how to keep the systems working efficiently [2].

vii.Lack of standards

Biogas technology operates freely without any laid-out standards to regulate it. This makes it hard to ensure quality control measures are undertaken.

viii.Availability of cheaper and convenient alternatives

Many rural communities are accustomed to using traditional sources of energy like firewood, charcoal kerosene, which is readily available freely in most cases and is considered convenient to use compared to biogas preparation and related investment and operational costs [75].
