| Abstract | This study consists of landfill census and experimental landfill gas measurement. The landfill
census was to identify the current status and future trend of municipal solid waste management
as practiced by sanitary landfill in Thailand. The landfill census was organized and carried out
by questionnaires to all municipalities in Thailand and random survey. Based on this
information, sanitary landfill and non-engineered landfill were found 11 % and 37 %,
respectively while the rest were open-dumped sites, (52 %). Most of the disposal sites were in
small scale and suffered by operation problems such as the lack of man power and heavy
machines and from the environmental impacts such as ground water contamination and odor
problem.
The research on landfill gas migration was carried out at Kampaeng Saen landfill in Nakorn
Phatom, Thailand. Its aim was to determine landfill gas migration and methane oxidation from
cover soil. From the age of the landfill that was 6 to 7 years, it was found that the gas
production was due to slowly decomposable solid waste. A flux of methane and carbon
dioxide was measured by closed flux chamber techniques. The average vertical landfill gas
migration found from two experimental runs were 20.3 g CH4/m
2
/d and 50.8 g C02/m
2
/d. The
methane emission from Kampaeng Saen landfill was found to be 0.34 percent of total country
emission.
In order to reduce methane emission which is more vigorous greenhouse gas than carbon
dioxide, a methane oxidation in landfill cover soil was determined as an important reaction by
which methane can be converted into carbon dioxide. From the study, the characteristics of
cover soil in Kampaeng Saen landfill found to promote the methane oxidation and the
oxidation zone was 50 cm below the ground level. Due to an assumption of zero lateral gas
migration, estimated methane oxidation rate was 4.45 g/m2
/d.
In addition, the impacts of the landfill to the Kampaeng Saen community were considered by
determining number of population and the change of land use in Kampaeng Saen area since
1989 when landfill was established. It was found that the landfill had both positive from
increasing the jobs for local people and negative impacts such as odor and groundwater
contamination. By compared between positive and negative impacts of landfill establishment
to the community, it can be concluded the Kampaeng Saen community grew without any
effects from the landfill. |
