An investigation was carried out to find the effect of climate on bio-gas production and composition of four different substrates viz. Ruminants (Cattle and goat) and non-ruminants (Pig and poultry). The results revealed thatSeason had profound influence on bio-gas production. The bio-gas production in summer season was significantly higher (0.0376 ± 0.32 m3)compared to monsoon (0.0366 ± 0.29 m3) and winter(0.0328 ± 0.24 m3) seasons. The methane concentration was higher and carbon dioxide concentration was lower in summer compared to monsoon and winter. The biogas composition was significantly different (p<0.01) during different seasons. In high altitude areas, where the mean ambient temperature variation is between 20–24ºC, for optimum bio-gas production and higher methane content, thermal insulation of all types of digesters are essential.
