The use of biogas digestion ha s definite advantage on environment and h ygene of the rural community. Unfortunately, this cannot be easily quantified. Thus co nstruction of digesters ha s to be justified economical l y on the consumption of gas and slurry alone. In the case of relatively small Thai pig farms, the energy usage in the farm household and piggery is sufficient to make small digesters economically viable . However these are not adequate to treat all the manure of the farm. Consideration should be given to other agricultural needs for energy not related to pig rearing and household sector. The other area that needs to be studied is the application of the digester slurry as a fertilizer.
