|Location of Project Activity
|China (Beijing City)
|Summary of FS Report
|Description of Project Activity
|The purpose of this research is realizing the project where project participants will avoid the methane emissions from municipal solid waste (MSW) landfill site in Beijing city in China as a CDM project. The target MSW landfill site is already closed from waste disposal and landfill surface is covered by soil. For avoidance of methane emissions from the degradable waste landfill body in anaerobic condition the project participants will set air injection and water circulation equipments and keep appropriate temperature of landfill body in aerobic condition.

|Duration of Project Activity/ Crediting Period
|2010 – 2016 / 2010 – 2016
|Baseline Scenario (including Methodology to be applied)
|Demonstration of Additionality
|Project participants could not make any direct revenues by methane emissions avoidance project itself with on-site aeration technique. There is no law or regulation to stipulate for application of on-site aeration technique in closed landfill site in China. Considering that investment costs would stand even 35.8 in millions of RMB, it would not realistic that this project could be realized without CER revenues. Untreated landfilling is common practice and the project activity without CER revenues or other public fund is implausible. Therefore the proposed project activity is additional and is eligible as a CDM project.
|Estimation of GHG Emission Reductions
|Annual average: 113,700t-CO2, Total: 795,900t-CO2/7years
|Monitoring Plan (including Methodology to be applied)
|Existing organic waste sampling
The baseline emissions of anaerobic methane generation could be calculated based on the FOD model. The characteristics of existing wastes such as the fractions of degradable organic carbon (DOCj) could be identified based on the existing organic waste sampling. The waste samples could be obtained by open excavation survey and/or on-site boring survey.
Monitoring of residual methane emissions
The amount of landfill gas emissions from each venting pipes could be measured monthly or at least quarterly. And the fraction of methane in the LFG should be measured with a continuous gas analyzer. Besides the average amount of landfill gas emissions from each surface capping area and the methane concentration could be measured by using flux box survey.
|Environmental Impact Analysis
|Discharge water from the closed landfill site should be collected and circulated by the on-site aeration technique applied in this project. Then quality of discharge water should be kept in appropriate condition and be prevented from water contamination. Chinese authority does not have any law or regulation as to operational modification of closed MSW landfill site for additional environmental impact assessment such as discharge water quality evaluation.
|Issues and Tasks for Project Materialisation
|The China government and the Beijing authority accept the possible good effect of this project; however, this project is the first case to apply this technology in China so far. This technology is applied only in the US. Therefore, this project should be a demonstration case. In addition proper landfill management with co-benefits is most acceptable to Chinese authority. Therefore the realization of this project as a CDM project will contribute to proper landfill management technique as well as contribute to environmental improvement and sustainable development in both urban and local communities in China.
|The project activity will bring about both environmental and socioeconomic good effects in community areas as follows:
