Abstract/ Executive Summary:

Khulna is located in the southwestern part of Bangladesh. Khulna is the third-largest city of Bangladesh where the livelihood depends on mostly agricultural practices and livestock farming. Thus there might have significant potential for biogas production. From this point of view the present study has been taken into consideration. A structured questionnaire survey was conducted to investigate the plenty of livestock resources, their energy consumption pattern, biogas production, and replacement of traditional energy consumption with biogas in 80 households which is selected randomly. The study found that total manure production is 3080125.5 kg/yr and residues production is 102252.34 kg/yr. 94 percent of the households are still using mud stoves as their first priority. Useful cooking energy demand in the case of the surveyed area comes out to be 77420 kWh per year. The total biogas demand of the study area to provide cooking gas and electricity is 56981.5 m³ per year whereas the total potential biogas production is 125838.18 m3/yr in the study area. The potential produced biogas will completely fulfill the biogas demand in the study area.

Program Area: Farm Mechanization

Commodity: Energy, Bio fertilizer, Livestock

Objectives:

To find out the biomass potential in the surveyed area i.e. cow dung and agricultural waste to calculate the amount of biogas that could be produced from the available resources in the study area.

Methodology:

Survey Procedure: For the present study Gangarampur Union was selected. Total 80 households from Gangarampur Union were selected randomly. A structured questionnaire survey was conducted to investigate the plenty of livestock resources, their energy consumption pattern, biogas production, and replacement of traditional energy consumption with biogas. The survey was conducted to the owner of the households. In some cases the comments from the housewife was also investigated. Biogas Calculation: In order to estimate biogas production, the biogas production rate from various sources developed by Ahmed and Bahauddin [9] has been used. Report showed that manure production rate respectively for cow/buffalo, goat/sheep/pork and hen/duck is 20 kg/d.c, 3 kg/d.c and 0.1 kg/d.c and human excreta production rate is 0.4 kg/d.c whereas biogas production rate is 0.037 m³, 0.052 m³, 0.074 m³, 0.074 m³ and 0.072 m³ per kg of manure from cow/buffalo, goat/sheep/pork, hen/duck, human excreta and organic waste respectively. The manure and biogas production rate from different sources is given.

Achievement/Findings:

The study and its findings are based on a household survey in the rural village of Bangladesh. The main purpose of the survey was to find out the cooking and lighting energy demand of the study area. These findings are also meant to be used as baseline information for biogas poly generation project. The study shows that among the total energy demand (cooking and lighting), cooking energy has the major share and lighting energy consumption is quite nominal in comparison, reason of which is the limited use of kerosene by the majority of households. Cooking energy consumption of households is observed to increase with an increase in income of households.
