Description of Project ActivityLaemchabang landfill site (approx. 6ha) in Laemchabang City, Chonburi Province, Thailand was appointed as the project site. The site has been owned and managed by Laemchabang Cityand currently been in operation, though a part of the landfill site has been completed and cloased. Since the landfill site has conventionally applied open dumping method, it is apparently assumed that the landfill site is in an anaerobic condition and it is expected that a large amount of methane gas (CH4) is emitted from the site. This project is to improve the anaerobic condition to a semi-aerobic condition by installing vertical and horizontal pipes for ventilation and drainage in the site. This will accelerate the degradation of waste and inhibit the emission of CH4. By the implementation of this project, it is expected to reduce the greenhouse gas by 14,499tCO2 per year on 6-year average from 2011 to 2016. The project will be implemented by SPC established in the host country, and the construction work will be completed at the end of 2010.

Category of Project ActivityWaste Management
Duration of Project Activity/ Crediting PeriodFrom 2011 to 2016/ From 2011 to 2016 (6 years)
Methodology to be appliedApply the new methodology for semi-aerobic improvement prepared in reference to NM0314 and AM0083.
Baseline ScenarioApply the current baseline scenario where "greenhouse gas is not recovered or burned, or partly recovered or burned."
For the project boundary, the situation before/after the implementation of the project is not changed, and the target is only the methane gas emitted from the landfill site.
Demonstration of AdditionalityThe proposals of "improvement without CDM," "gas power generation/gas distribution," and "excavation to retreat waste" are possible as a baseline scenario, but it does not expect to implement from economical and technical viewpoints. The only applicable option with additionality is "not to recover or burn greenhouse gas, or partly recover or burn it." This option may earn credits by applying CDM.
Estimation of GHG Emission Reductions86,993tCO2 per year
Monitoring PlanApply the monitoring method based on the new methodology newly submitted.
Measure the gas emission at vertical vent pipes and the earth surface. Also measure the quality of leachate from the landfill site and the odor of the surrounding area to check the situation of the neighboring environment.
For the emission amount from vent pipes, measure the flow rate and the concentration at all vent pipes.
Measure the emission amount from the earth surface by sampling using the chamber method.
Since the local climate condition is tropical and classified in wet and dry seasons, take the measurement in each season.
Environmental Impact AnalysisThere will be no adverse environmental impact because methane gas from the site will be reduced, and the situation of leachate and odor from the site will be improved by the implementation of this project. There will also be no adverse impact on economic and social aspects.
Project FeasibilityThis project does not earn any profits other than selling CER. Therefore, the unit price of CER is the key to make the project feasible.
If the unit price of CER is around 1,800 yen/tCO2, the project becomes feasible.
Pollutants Emissions ReductionSince the project improves the situation of leachate and odor, it may contribute to the needs for environmental improvement in the host country. In the field of co-benefit, it corresponds to the "implementation of reasonable waste disposal."
