Gloria S.A. (a Peruvian firim) has developed a new method for making Chinese-type biodigesters having a capacity of 10-15 m3. The technology is suitable for rocky areas or htose abundant in expanding clay. The biodigester requires an area of no more than 24 m2 and is installed below the ground. Manure and vegetable waste mixture is used as feed (about 9 % solid content). A 15 m3 capacity digester can produce 3.75 m3 biogas per day along with 130 litres of liquid organic fertilizer. Annual production of biogas is estimated to be 3 metric tonnes. Cost of construction and installation is 375 USD. The technology is available for transfer.
