In this paper; an attempt has been made to design and test the performance of a portable floating type biogas plant of volume capacity 0.018 m3 for outdoor climatic condition of New Delhi; India. The field study has been carried under the monsoonal season of New Delhi; India. In this experiment; we have taken an aluminium made digester of 30 Kg slurry capacity for batch system. In the batch system; the slurry has been added once to the digester for whole duration of the process. The rate of biogas production with slurry temperature has been observed.

It has been observed that (i) the biogas production depends strongly on slurry temperature and (ii) the retention period is nearly 85 days. The range of slurry and ambient temperature of atmosphere recorded during the observed period have been found as 26 to 42 ºC and 30 to 40 ºC respectively. Physical and chemical analysis of biogas and slurry have also been carried out. Further; the CO2 mitigation and carbon credit has also been evaluated for the present system.
