Oth er Benef it s

Integration of Bio-digester` Total water Generated (Kitchen waste @0.25 kg, Night soil@ 0.2 kg/person) = 45 kg` Gas Production (Kitchen waste @0.03m3/kg, Night soil@ 0.05 m3/kg) = 1.75 m3` Size of Bio-digester = 9.04 m3` Adopted Bio-digester = 10 m3` Biogas Consumption of Stove (BSP Model)= 0.44 m3/hr` Biogas burning hour = 3.98 hr

It is sufficient to meet the cooking energy need of family with 6 members.
