2 About Bangladesh Independence: 1971 Area: 147,570 sqkm Population: million (UNFPA) Rural population: 70% Urban population: 30% Temperature: Religion: Muslim 88.3% Per capita income: US$ 400 Language: Bengali

3 Status of Biogas in Bangladesh 1972: Dr. M A Karim constructed the first biogas plant at Agriculture University : EPCD constructed 250 floating dome and 119 fixed dome biogas plants Engineers of LGED and Scientists of BCSIR constructed 300 biogas plants : LGED constructed 5,000 plants : BCSIR constructed 22,000 plants 2005-onward: GS constructed 23,000 plants 2006-onward: IDCOL constructed 24,000 plants : M/O Youth constructed 3,000 plants : Others constructed 3,000 plants : BCSIR constructed 3,000 plants

4 Systems for IDCOL Plants Size: to gas production capacity per day Subsidy: US$ 109 Loan: 85% of the plant cost excluding subsidy Design and supervision by company Purchase of materials and payment of workers by the plant owner Warranty: 2 years After sale service: Company staffs visits customers house every month to supervise the plant Success rate: 98%

5 System followed by others Plant size above 6m 3 No loan and subsidy Design and supervision by GS engineers Purchase of materials and payment of workers by the plant owner Warranty: 2 years After sale service: GS staffs visits customers house regularly to supervise the plant Success rate: 98% Technical fee: 10% of the plant cost

7 Impact of Credit Support Initial investment reduced, hence the technology becomes affordable The implementing agency must ensure quality to achieve recovery of loan The staffs of the implementing agency must visit customers house at least once a month to collect monthly installment, when they can ensure supervision, give necessary instruction to the customer

8 Problems in existing model Cannot shift when needed High cost of construction Takes long time to construct Highly dependent on skilled manpower Cannot work during monsoon A good numbers of plants stopped due to construction fault Sub-soil water creates problem

9 Power Generation Using Biogas Power generation using biogas was unknown in Bangladesh In 2006 Grameen Shakti installed one 2KW capacity petrol generator and converted to run with biogas Seeing its success, many biogas plant owners installed petrol, diesel, natural gas generators to run with biogas At present about 300 generators are running with biogas of size upto 260KW. Some of those are made for biogas.

29 Recommendations Identify more portable models at home and abroad Identify five models for field test Construct 5 plants of each type through 5 Pos Record performance for one month Analyze data and share experts opinion Identify one or more models for wide replication
