Study Report

Note: JCM proposed methodology, and calculation sheet are the result of the study. They have neither been officially approved, nor are guaranteed to be officially approved under the JCM.
Description of Project/ActivityThe proposed project will set up the source separation and collection system of organic waste within Binh Dien Market in Ho Chi Minh City, Vietnam. All the organic waste that would be transported to Da Phuoc waste treatment complex will be treated by way of anaerobic digestion. The biogas from anaerobic digestion would be utilized for heat and power generation. The residual waste from the digestion will be composted and the compost will be distributed to nearby farmers.
JCM MethodologyEligibility Criteria
Criterion 1Anaerobic digesters and the cogeneration system that is fuelled by the biogas are to be installed.
Criterion 2The project has a maintenance plan that outlines a checklist, responsibility guidelines and safety guidelines.
Criterion 3The materials to be fed into the anaerobic digesters are organic waste that would have been disposed at a landfill site in the absence of the project activity.
Criterion 4Biogas recovery rate of the anaerobic digesters is not less than 30 Nm3/ a tonne of organic waste. The manufacturer conducts a test and the results from the test are to be validated by a third-party which then is submitted to TPE for project validation.
Criterion 5Overall efficiency of the cogeneration system is not less than 80%. For JCM validation, a catalogue on product specifications must be provided to the TPE for confirmation that the efficiency advertised is achieved.
Criterion 6Air tightness test is to be conducted to prove that there is no biogas leakage from the anaerobic digesters.
Criterion 7The plant has a treatment capacity of more than 50 tonnes/day.
Criterion 8The plant has a desulfurization apparatus before the gas enters the cogeneration system.

Calculation of Reference EmissionsREy = RECH4,SWDS,y + REEC,y * EFe,y + (EGthermal,ythermal )*EFFF,CO2

REy Reference CO2 emissions during the period of year y [tCO2/y]
RECH4,SWDS,y Reference emission occurring in year y generated from waste disposal at a SWDS during a time period ending in year y [tCO2/y]
REEC,y The quantity of net electricity generation that is produced as a result of the implementation of the project activity in year y [MWh/y]
EFe,y CO2 emissions factor of electricity in year y [tCO2/MWh]
EGthermal,y The net quantity of steam/heat supplied by the project activity during the year y [TJ]
EFFF,CO2 CO2 emission factor of the fossil fuel that would have been used in the reference plant [tCO2/TJ]
ηthermal The efficiency of the plant using fossil fuel that would have been used in the absence of the project activity
Monitoring Method
  • Wx Amount of waste input Continuously
  • REEC Amount of electricity generated (Electricity) Continuously
  • EGthermal Amount of heat/steam generated Continuously
  • PECy Project electricity consumption (electricity) Continuously
  • PFCy Project fuel consumption Monthly
  • fy Fraction of methane captured at the SWDS Annually
GHG Emission ReductionsERy = REy -PEy
980=1,019-38.9
Environmental ImpactsThe project will reduce the number of transportation of waste to the landfill and thus reduce the emissions of CO2, NOx and PM associated with the waste transportation.
Project and its Financial PlanThe total amount of initial investment and first year operational cost is JPY720,700,000 The project participants intend to invest JPY390,700,000 and seek financial support for JCM models projects.
Promotion of Japanese TechnologiesWe believe that the introduction and popularization of the large scale methane fermentation facility that this project promotes is holistically important for the policy making and planning of the subject city’s waste management system. The economical and environmental benefits of reducing organic waste are indicated and we feel that cooperating with the regional area’s People’s Committees would be the most effective in planning and implementing.
Sustainable Development in Host CountryThis project will not only contribute to the reduction of GHG emissions but, reduction of solid waste, improves the management level of MSW and contribute to the energy supply.
