Truong Van Minh, a local farmer, said his family has applied thetechnology since 2012 and can save 400,000-500,000 VND (19-24 USD) permonth.
It has also created a healthy environment for not only his family but also his neighbours, he added.
The province has so far constructed over 1,100 biogas plants, eachworth 10 to 25 million VND ( 235- 1,190 USD). The plants are not onlyeconomically efficient but also environmentally friendly.
The biogas technology is one of the effective measures to createclean energy sources as well as reduce deforestation for firewood andgreenhouse gas emissions. Biogas is produced from the decompositionprocess of animal and plant waste in the absence of oxygen.
With more than 760,000 heads of cattle and 2.3 million fowls, theprovince should expand the model among people, especially ethnicminorities, in an effort to solve environmental pollution and graduallydrive back epidemics.-VNA
