Samtse: The National Jersey Breeding Centre (NJBC) in collaboration with the Bhutan Bio-gas Project installed a 75 cum bio-gas digester, one of its first kinds in the country. This is in keeping with the core values of the Gross National Happiness on ‘Self Reliance and Inclusive Green Socio-Economic Development’.
Unlike bio-gas digester, dung collected and stored in the tanks were not able to trap methane gas and reduced greenhouse gas emissions. By capturing methane and using it as fuel, it is being prevented from releasing into the atmosphere and at the same time creating renewable and clean energy. It will also reduce water contaminations (surface, run-off and ground water resources) as most of the dungs will be collected and diverted into the digester, further reducing foul smell during winter.
Ten households of livestock attendants were connected with the gas supply line and have been enjoying clean and uninterrupted supply of cooking gas since installation. With such initiative, it is estimated that every household will save the cost of one commercial gas cylinder or 15 litres of kerosene oil every one and half month period.
The planning, drawings and design for digester were prepared by the Bhutan Bio-gas Project with technical support from SNV and fund support from RGoB and ADB.
Considering the success, the centre plans to expand the gas supply line to another eight households, if budget commitments are met. At present, the gas is used only for cooking and heating water by the livestock attendants.
