Relevant dates for the project activity:
The project activity was registered as a CDM project on 06/06/2012.
The start date of the CDM crediting period is 06/01/2013.
Duration of this monitoring period: 06/01/2018 – 05/01/2020
1. General description
This Monitoring Report has been developed for the purpose of the Gold Standard verification
exercise for greenhouse gas emission reductions achieved by the project activity titled “Avoided
methane emission through aerobic composting at Vietstar municipal solid treatment facility” as
per relevant requirements for the period 06/01/2018 – 05/01/2020 (both days are included).
The proposed project activity -Vietstar municipal solid waste treatment facility - is located
within the territory of Tay Bac Solid Waste Treatment Complex Zone, in Ho Chi Minh city, Viet
Nam. The project is invested and operated by the private owned entity namely Vietstar Joint
Stock Company, specializing in economical wastewater treatment technology and investment in
residential solid waste plants.
The main purpose of the proposed project is to produce aerobic compost from MSW that would
have been left to decay anaerobically in waste landfills. The project activity is implemented in
two phases. The first phase has completed construction and started operating from December
2009. The designed capacity of phase one is 216,000 tons of solid waste per year (600 tons per
day, assuming 360 days per year) and the proposed product of organic compost is 26,420 tons
annually. The second phase has started operating from 24 November 2014; the treatment
capacity is doubled with the total designed capacity of 432,000 tons of solid waste per year with
daily waste reception of 1200 tons and the proposed product of organic compost as 53,568 tons
annually. About 4.66% of the total waste is recyclable plastic portion that will be recycled by
utilizing the Japanese advanced technology to produce expectedly 5,400 tons of recycled plastics
per year. The inert portion separated from composting process and the non-degradable waste is
designed to be transported and disposed in Phuoc Hiep landfill site number IA (hereafter called
as PhuocHiep IA) close to the MSW treatment plant site. The final product of organic compost
will be sold as bio-fertilizer to users.

In the absence of the project activity collected municipal waste containing approximately
70.81% organic matter on average would be disposed in dumpsites. The project reduces methane
emissions by establishing and operating composting facilities to treat organic matter collected
from municipal waste. The project results in the avoidance of a large quantity of methane (CH4)
that otherwise would have been released into the atmosphere due to the anaerobic decay of
organic waste in landfills. A total expected CO2 equivalent emission reduction is 1,814,928tCO2
over the fixed crediting period of 10- year period.
2. Calculation of emission reductions

3. Sustainable Indicators and Parameters monitored according to the monitoring plan
According to the requirements of the Gold Standard, the project activity must be assessed against
a matrix of sustainable development indicators. The contribution of the proposed project activity
to the sustainable development of the country is based on indicators of local/ global
environmental sustainability, social sustainability & development and economic & technological
development.
Five indicators were added to the monitoring plan. All documents regarding these additional
parameters will be presented to the DOE during the on-site visit.
a. Monitoring procedures for “Quantitative employment and income generation”
Indicator No.1 Quantitative employment and income generation
Monitored parameter: Employment creation/household income
Description: The project creates jobs by employing people during the
construction and operation phase.
A number of waste-pickers are directly employed by the
project proponent at the sorting facility. They are provided
with proper safety equipment and health insurance. They
