Comparative Estimation of Greenhouse Gas Emission from Wastewater in Thailand Using Different Methodologies

Abstract:
The study was conducted to estimate the greenhouse gas emissions from domestic and
industrial wastewater treatment in Thailand by, following the revised 1996 IPCC guideline on
National Greenhouse Gas Inventory and 2006 IPCC guidelines on National Greenhouse Gas
Inventory during 2000-2008. The aim was to assess and analyse the results between these two
methodologies, in terms of amounts of emission, data input, accessible data and the suitability
of data using. The CH4 emissions were estimated according to IPCC categories, namely
domestic wastewater and industrial wastewater, while, N2O emissions were estimated for
human sewage and wastewater effluent.
The results, following the revised 1996 IPCC guideline showed that the CH4
emissions from domestic wastewater handling were higher than when following 2006 IPCC
guideline, by about 1.69 times in 2000, 1.58 times in 2005 and 1.67 times in 2008, which
were 78.24 Gg, 75.07 Gg and 82.81 Gg, respectively. These were due to the difference of the
parameters used, namely the fraction of population income group, the degree of utilization of
treatment or discharge for each income group, recommended in the 2006 IPCC guideline.
These parameters were categorized by GPP to classify urban and rural high and low incomes.
In the estimation of CH4 emissions from industrial wastewater treatment, tier 3
(bottom up data) and tier 2 were compared, using different disaggregate levels of data. It was
found that accurate COD value, wastewater volume from individual industry (disaggregate
level) produced higher CH4 emissions, than using the average value in tier 2. The result tier 3
(bottom up data) was higher than using tier 2, by about 1.71 times in 2000, 1.74 times in 2005
and 1.75 times in 2008, which were 155.37 Gg, 194.10 Gg and 236.37 Gg, respectively.
N20 emissions from human sewage were 1.92 Gg in 2000, 1.96 Gg in 2005 and
increased to 2.00 Gg in 2008. N20 emission from wastewater effluent was 1.66 Gg in 2000,
1.70 Gg in 2005, and 1.74 Gg in 2008. The emissions have increased slightly, due to the
increase in population and the increase of average protein consumption.
In order to reduce the uncertainty and avoid the overestimating in the improvement
activity data collection system is essential. The data have to be collected systematically by the
responsible organizations, and experimental research is encouraged to obtain the country
specific emission factor.
