Economic Evaluation of Different Size of Biogas Plants In Chhattisgarh (India)

Abstract

In order to determine the working efficiency and economical size of biogas plants in respect of house hold cattle and family members, a study was carried out during 2007-08 in Chhattisgarh State, India. Fifteen blocks were selected randomly covering 117 biogas plants. Out of them, 99 plants (85 %) were found in working condition for which economic analysis was carried out. Survey results revealed that economically different sizes of biogas plants i.e. 2- 8 m3 were useful in the study area. On an average, the whole initial investment could be recovered in an about 3- 8 years. The annual income of different size of biogas plants from 2 m3, 3 m3, 4 m3, 6 m3 and 8 m3 will be Rs 3620, Rs 5273.6, Rs 4215, Rs 4565 and Rs 4612, respectively. The cost of operations of different size of biogas plants (2-8 m3) were observed in the range 2.73- 4.0 Rs/h. The size of most economical biogas plant was 3 m3 (B/C= 1.23) followed by 2 m3 (B/C= 1.06).

“…Table 8 gives the amount of organic fertilizer that would be produced and the revenues that could be achieved from its sales. The cost of a 50 kg NPK fertilizer is about 28 USD 30 . Hence, this value was used to calculate the cost of organic fertilizer that would replace the chemical fertilizers.…”

“…The cost of a 50 kg NPK fertilizer is about 28 USD. 30 Hence, this value was used to calculate the cost of organic fertilizer that would replace the chemical fertilizers. After the costs of removal of processing, labor, packaging, quality assurance, marketing and other costs estimated at 50% of the gross earnings from organic fertilizer sales 31 and marketing, the net revenue was estimated.…”
