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

Summary of calculation of emission reductions are as follow1:

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.
