Reports of CDM/JI Feasibility Studies: FY2007


* The study result was revised in Feb. 2009.
Title of Feasibility Study (FS)Biogas Electricity Generation through Anaerobic Digestion of Waste
FYFY 2007
Main Implementing EntityTaisei Corporation
FS Partner(s)The People’s Committee of Can Tho City, Hokkaido Electric Power Co., Inc., Sojitz Research Institute, Ltd.
Location of Project ActivitySocialist Republic of Viet Nam
Summary of FS ReportPDF (443KB)
Description of Project ActivityIn the proposed project the municipal wastes delivered to Tan Long disposal center from Can Tho City as well as from the neighboring regions will be segregated for mechanically recovering biogas to generate electric power to be supplied to the external grid network eventually. The disposal treatment process enables stopping the selected organic residues from being land-filled, resulting in decreasing methane gas emissions if the proposed project not implemented.
Targeted GHGCH4、CO2
Category of Project ActivityWaste Management
CDM/JICDM
Duration of Project Activity/ Crediting Period2009-2020/ 2010-2019
Baseline Methodology/ AdditionalityIn the proposed project, the approved methodology AM0025 “Avoided emissions from organic waste through alternative waste treatment processes” may be applied.
Substitute scenarios are shown as under:
<For Waste Disposal Treatment>
  • M1:The project activity (anaerobic digestion and electricity generation) not implemented as a CDM project;
  • M2: Disposal of the waste at a landfill where landfill gas captured is flared;
  • M3: Disposal of the waste on a landfill without the capture of landfill gas.
<For Electric Power Generator>
  • P1: Power generated from by-product of one of the options of waste treatment as listed in M1 above, not undertaken as a CDM project activity.
  • P2: Existing or Construction of a new on-site or off-site fossil fuel fired cogeneration plant.
  • P3: Existing or Construction of a new on-site or off-site renewable based cogeneration plant.
  • P4: Existing or Construction of a new on-site or off-site fossil fuel fired captive power plant.
  • P5: Existing or Construction of a new on-site or off-site renewable based captive power plant.
  • P6: Existing and/or new grid-connected power plants.
It is demonstrated that the baseline option for waste treatment is M3 and the baseline option for power generation is P6, therefore the baseline scenario is applicable to the methodology. The baseline scenario for the project activity is described as “the disposal of the waste in a landfill site without capturing landfill gas and the electricity obtained from the grid”.
Estimation of GHG Emission ReductionsApproximately 101,200t-CO2e/10years
Monitoring MethodologyMonitoring mandates will be employed by ACM0025(Version 10) specifications.
The special purpose company (SPC) will commission the operation and maintenance of the waste treatment plant to Urban Public Works Company (UPWC), which is the project participant of the Host Country. UPWC is in charge of monitoring as well.
Environmental Impact AnalysisThe following environmental impacts are expected from the proposed project activity;
  • impact on air quality,
  • impact on water quality,
  • impact of noise,
  • impact of vibration.
The project activity will be designed in consideration of environmental impact and mitigation measures will be proposed in EIA when the project activity does not meet any relevant environmental standards in Vietnam.
Issues and Tasks for Project RealisationThe projected IRR will be minus when this project is completed in 2020 (10th year after CER revenue is fixed), and the prospective effect of this project will not be worth its investment cost. Therefore, it is concluded that this project will not be a successful CDM project, and that this project should be resigned to implement.
