Describe (to the extent possible) how the activity is compatible with and supportive of national economic development and socio-economic and environment priorities and strategies

As energy supply and demand issues and protection of the global environment have become the focus of worldwide interest, NEDO is promoting energy conservation model projects in Asian countries including China to contribute to the effective use of energy and improvement of environmental pollution.

In China, as strong national policy for energy conservation and environmental protection, relating laws have come into effect.

As a joint project between Japan and China, this project will contribute to reductions in local and regional pollutants such as SOx, NOx and dust as well as greenhouse gas mitigation such as CH4, CO2.

The economic benefits of the project include reduction in energy consumption in textile factory .

E. Calculation of the contribution of activities implemented jointly projects that bring about real, measurable and long-term environmental benefits related to the mitigation of climate change that would not have occurred in the absence of such activities

1) Estimated emissions without the activity (project baseline):

Description of the baseline or reference scenario, including methodologies applied:

(Baseline)

In Harbin city, the municipal waste is not incinerated, but landfilled. At the existing textile factory, they get steam for power generation, for processing and for the heating by the existing boilers, which are fueled by coal. The landfilling causes huge amount of methane(CH4) emission from the site, and combusting coal at the factory generates carbon dioxide(CO2).

The AIJ project in Harbin city aims to build the Garbage Incineration Plant of Harbin City, to recover the heat from incineration and to supply the heat to the existing plant. In this way, CH4 emission from the landfill site should decrease and also CO2 emission should be reduced by reducing consumption of coal at the existing plant.

We shall define our baseline as below.

Present condition: The municipal waste to be combusted by the Harbin city project is now landfilled and so generating CH4.

2. Present condition: At the textile factory in Harbin city, combusting coals for generating steam causes CO2 emission.

(Calculation)

1 . The amount of CH4 emission from the municipal waste landfill( ECH4 )

ECH4 = G × f1 × f2 × f3 × f4 × 16/12 = 2,164.5 t-CH4/a

G : Annual amount of municipal waste (the waste expected to be incinerated after

executing the project); 57,646 t-waste/a

f1 : ratio on treating waste by land-filling ; 1.0

f2 : the content of organic carbon in waste ; 0.1788

f3 : ratio on gasification of organic carbon in landfill ;0.63

f4 : fraction of C as CH4 to C as biogas ; 0.25

2 . CO2 emission from the existing boilers (ECO2 )

Eco2 = W1 × C1 × Bf1 × 44/12 = 95,642.8 t-CO2/a

W1: coal consumption by the existing boilers (average consumption of the local coal for the latest three years ) W1=(69,000 t/a + 61,000 t/a + 58,000 t/a) / 3 = 62,666.7 t/a C1 : the carbon content of the local coal (Hegang coal) ; 48.4 % Bf1: the burning efficiency of the existing boiler ; 86 %

(Results)

By the calculation above, CH4 and CO2 emissions at baseline are:

( 1 ) CH4 emission

ECH4 = 2,164.5 t-CH4/a

( 2 ) CO2 emission

Eco2 = 95,642.8 t-CO2/a

2) Estimated emissions with the activity:

Description of the scenario, including methodologies applied:

(Concept)

Although IPCC Guideline suggests that CO2 emission caused by incinerating waste derived from biomass raw material should not be considered as net anthropogenic CO2 emission, both Japanese participants and Chinese participants agreed to take note on the view that some part of decomposed carbon from municipal waste derived from biomass raw material will not degrade to form CO2 but stay as carbon in the municipal waste landfill, therefore, when the municipal waste is incinerated, net CO2 emission will occur.

Therefore, both parties agreed to calculate in two ways, one according to IPCC Guideline, the other taking non-degrade carbon into account.

Since the difference between two methods exists in the calculation of CO2 emission generated by incinerating waste derived from biomass raw material, calculation according to IPCC Guideline is given first as follows:

In the calculation below, we consider only municipal waste which will be incinerated after completion of the Harbin project. The rest of the municipal waste will be landfilled as it has been landfilled in the baseline case, and will give the same amount of GHG emissions for the baseline case and the project case.

PROJECT CASE:

CH4 emission from landfill becomes zero because the municipal waste is incinerated.

Further, existing boilers which has been supplied heat energy for the textile factory require less coal because some part of the heat requirement for the factory is covered by heat recovered from incineration plant.

On the other hand, the incineration plant of Harbin project requires electricity, accordingly net CO2 emission occurs.
Furthermore, coal, an auxiliary fuel for the incineration plant, is burnt when the calorific value of the waste is not enough, and net CO2 emission occurs.
When incinerating the waste which have anthropogenic origins, such as plastics and chemical fabrics, net CO2 emission occurs.

(Calculation)

1 . The amount of CH4 emission from the municipal waste landfill (ECH4 )

ECH4’= t- CH4/a

2 . CO2 emission from the existing coal fired boilers (E 1')

E1’ = W1’ × C1 × Bf1 × 44/12 = 63,497.6 t-CO2/a

W1’ : coal consumption by the existing boilers after executing the project

W1’= W1 - H1x103 /Q1 = 62,666.7- 72.98 x 103/3.465 = 41,604.7 t/a

Q2 : calorific value of the local coal ; 4.62 Gcal/t

C1 : the carbon content of the local coal (Hegang coal) ;48.4 %

Bf2 : the burning efficiency of the incineration boiler ; 99 %

Calculations above are based on the IPCC Guideline in which CO2 emission generated by incinerating waste derived from biomass raw material should not be considered as net anthropogenic CO2 emission. As written on the first part of this section, Japanese participants and Chinese participants agreed to calculate CO2 emission generated by incinerating waste derived from biomass raw material, taking non-degrade carbon into account as shown below:

  1. CO2 emission by combusting the organic carbon which is not degraded in the municipal waste landfilled (E5’)

    E5’ = G × f1 × f2 × (1-f3) × 44/12 = 13,983.3 t-CO2/a

    (0) ..for IPCC Guideline approach

    G : Annual amount of municipal waste (the waste expected to be incinerated after completion the project); 57,646 t-waste/a

    f1 : ratio on treating waste by land-filling ; 1.0

  • f2 : the content of organic carbon in waste ; 0.1788

    f3 : ratio on gasification of organic carbon in landfill ; 0.63

7 . CH4 and CO2 emissions after completion of the project

(1) CH4 emission(ECH4’)

( ECH4’) = t-CH4/a

(2) CO2 emission (Eco2’)

Eco2’=E1’ + E2’ + E3’ + E4’ + E5’ = 92,184.9 t-CO2/a

(78,201.6)

8 . Reduced amount of CH4 and CO2 emissions derived by subtracting the amount after executing the project from the baseline amount

(1) Reduced amount of CH4 (RCH4)

RCH4 + ECH4 - ECH4’ + 2,164.5 - 0 = 2,164.5 t-CH4/a

(2) Reduced amount of CO2 (Rco2)

Rco2 = Eco2 - Eco2’ = 95,642.8 - 92,184.9 - 3,457.9 t-CO2/a

(78,201.6) (17,441.2)

Transfer of environmentally sound technologies and know-how Describe briefly

Transfer of Municipal Waste Incineration Technology

The municipal waste incineration plant consists of fluidized bed type incinerator, waste heat boiler, combustion gas treatment facility and so on. Steam is recovered from waste heat generated in incinerating municipal waste.

The project demonstrates that recovered steam can replace steam generated from combustion of coal.

Capacity Building

H. Additional comments, if any, including any practical experience gained or technical difficulties, effects, impacts or other obstacles encountered

1) Any practical experience gained:

Since the Project is a Model Project, dissemination activity of the technology through demonstration operation is planned in the final stage of overall project schedule. A lager effect of energy conservation and environmental improvement would be expected through dissemination of the technology in the future

2)Technical difficulties:

Since the municipal waste incineration technology had been widely disseminated in Japan and enough practical and commercial experience has been already compiled, the technology is highly reliable. By this reason, technical difficulty does not exist.

3) Negative impacts and/or effects encountered:
