Nepal has a history of over 50 years of modern biogas technology development. The country saw the introduction of the first biogas digester in 1955. Father B.R. Saubolle built a demonstration biogas plant at St. Xavier’s School, Godavari, Lalitpur ( Two 200-litre metal oil drums were used, one as a digester and the other as a gas holder). It took almost 20 years to get the government’s attention towards biogas technology. In 1975/76, the first biogas promotion programme was launched by a government agency. With the success of this brief programme, the number of biogas plants started to grow in the country. The biogas sector got momentum as the government with support from the Government of the Netherlands initiated the Biogas Support Programme (BSP) in 1992. This section tries to document major events in the development of the biogas sector in Nepal. In doing so, the effort has been made to highlight development in three aspects, viz. institutional development, policy/programmes, and technological development.
