(Including running cost)

  1. Costs of the project are provided by Japanese side, including cost of project design and other transaction cost.
  2. Cost of AIJ component refers to costs of the hardware including all equipment and facilities provided by Japan side, which were evaluated jointly by experts on both sides.
  3. It is defined here as life cycle yearly averaged incremental cost for CO2 emission reduction against the given baseline.
  4. Case 1: CO2 emission from the degradable organic carbon (DOC) combustion, that is not degraded in the municipal waste landfill, is taken into account. It will result in less GHG emission reduction and higher avoided cost.
  5. Case 2: It is opposite to the Case 1. Such CO2 emission is not taken into account for the reason that the net emission from biomass combustion is zero according to IPCC Guideline in 1996. Similarly, CO2 emission from those biomass related municipal waste incineration that originally form CH4 in the landfill in the baseline case, is also not taken into account. The results based on carbon balance calculation in this case 2 are shown in the parentheses in the report.

5) Mutually agreed assessment procedures:

Describe the procedures, including name of organizations involved :

Basic Agreement concerning the execution of this project was concluded between NEDO and SDPC and PCHLJ on September 3, 1998.

NEDO entrusted EBARA to execute this project on Japanese side on December 4, 1998.

EBARA and PCH concluded the Execution Document (ED) that described the concrete specification of this project on March 12, 1999 and started the design and engineering work.

As determined in ED, HMWIP shall have responsibility to record and provide technical and economic data. These data will be necessary for calculation of the GHG emission level both for baseline and the AIJ project and for the emission reduction cost, as well as for the subsequent reporting period.

HMWIP and EBARA shall submit the report on the data listed as above to MOST and NEDO before and after completion of the test run for review.

Based on the data available, ITEESA, Tsinghua University shall make feasibility study on the eligibility of the AIJ project and on assessment of the environmental benefits relating to the GHG emission reduction, as well as on the methodological issues in close co-operation with HMWIP and EBARAs’experts, with a view of preparing study report and draft report in uniform reporting format, to be submitted to both governments.

a) Please ensure that detailed contact information for all organizations mentioned is reported under section A.2 above.

a. In the case of joint reporting, the report is submitted by the designated national authority of one participating Party with the concurrence of all other participating Parties as evidenced by attached letters issued by the relevant national authorities;

b. In the case of separate reporting, the reports are submitted separately by the designated national authority of each and every participating Party. Information will only be compiled once reports have been received from all participating Parties.

For the activity:

* This report is the first report covering the activities at AIJ project feasibility study and AIJ project design stage, and copies of letters of endorsement by each designated national authority of Parties are attached.

Describe:

MOST and NEDO signed the "Memorandum of Understanding on Cooperation in The Model Project for Utilization of Waste Heat from Incineration of Refuse in Harbin of China as an AIJ Project under the Pilot Phase" on September 25, 1998.

The Ministry of International Trade and Industry of Japan (MITI) approved this project as Activity Implemented Jointly - Japan Program on June 17, 1998.

The Japanese government confirmed this project as Activity Implemented Jointly (AIJ) under pilot phase on June 23,1999.

MOST authorized by Chinese government, confirmed this project as Activity Implemented Jointly (AIJ) under pilot phase on July 9,1999.

2) This report is a joint report:
  • Yes, forward copy of agreement/endorsement by the designated national authorities involved
    No, this is a separate report. The reports are submitted separately by the designated

national authority of each and every participating party.

3) General short comment by the government(s) if applicable:

This is the first project report. The system boundary design and technical basic data were preliminary checked among the Chinese and Japanese experts. The environmental benefits and methodological and technical issues were addressed on the project specific basis. On the other hand, due to insufficient data availability and lack of uniformed methodology guidelines the results reported here may be subject to modification. Hopefully with the further progress of the project activities, more monitoring information on emissions and experiences in methodologies will be built up, and therefore the subsequent reports could be updated later on.

C. Compatibility with and supportiveness of national economic development and socio-economic and environment priorities and strategies

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 environment.

In China, strong national policies, laws and regulations for energy conservation and environmental protection have come into effect. The urban waste disposal and its compre-hensive utilization have been listed as one of the focused issues for environment protection and social development in urban planning in China.

As an AIJ pilot project between Japan and China, this project will contribute to efficient use of energy and consequent protection of the local environment in China as well as CH4 and CO2 emission mitigation by adopting advanced technology and equipment provided by Japan in the Harbin Municipal Waste Incineration Plant. Therefore the AIJ activity is compatible with and supportive of national socio-economic environment priorities and strategies.

D. Benefits derived from the activities implemented jointly project

Whenever possible, quantitative information should be provided. Failing that, a qualitative description should be given. If quantitative information becomes available, it could be submitted using the update(s). (If the amount of quantitative information is too large, the source could be indicated.)

Item Please fill in

Describe environmental benefits in detail:

CH4 emission generated from the municipal waste that would have been disposed in the landfill, otherwise, will be reduced.

Emissions of pollutants, such as SOx, NOx, soot and smoke that would have accrued from coal fired steam boiler, otherwise, will be avoided, due to the related coal fuel consumption for the steam supply will be replaced by those generated from the municipal waste incinera-tion.

Do quantitative data exist for evaluation of environmental benefits?

Yes. Total annual GHG emission reduced is estimated as 42,959.8 (62,895.8) ton -CO2 equivalent in which CH4 emission reduction is 2,164.5 ton - CH4 annually, CO2 emission reduction is –2,494.6 (17,441.1) ton -CO2 annually.

Describe social/cultural benefits in detail:

Do quantitative data exist for evaluation of social benefits?

No.

Describe economic benefits in detail:

Cost of coal consumption for steam generation will be reduced. Cost of urban waste landfill facilities will be reduced.

Do quantitative data exist for evaluation of economic benefits?

Yes.

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:

System Boundary:

This AIJ project is a waste disposal project. So the baseline case is the municipal waste landfill in Harbin city in absence of the AIJ project. According to the project specific baseline approach, the system boundary design for the AIJ project will be illustrated as in the Figure 1.

The direct emission levels from major process activities both in baseline case and the AIJ project are covered within the system boundary.

Image

Fig.1 System boundary* of the municipal waste incineration

AIJ project and its baseline case

*: Due to limited capacity of the FBC incineration boiler which can not replace the whole existing industrial boiler, but part of its capacity as shown in the system boundary diagram. While the remaining capacity of the existing boiler is still in operation both in baseline and AIJ project cases, and therefore is not shown in the diagram.

(Baseline)

The baseline of the AIJ project could be defined as below.

1. The municipal waste in Harbin city is not incinerated, but collected and put into landfill where large amount of methane (CH4) emission are accrued.

2. Meanwhile at the existing Harbin Textile Printing and Dyeing Works, where the Municipal Waste Incineration Plant will be located, the steam for heating and part of electricity demanded are generated by the existing coal fired CHP boiler in the plant which accrues CO2 emission.

3. The CO2 emission from the biomass in the municipal waste landfill is not taken into account, based on the IPCC methodology by which CO2 emission from biomass is recyclable and is regarded as zero emission. See Box 1 in detail.

In the AIJ project case, the Municipal Waste Incineration Plant will be built to recover the heat from the municipal waste incineration, and the recovered heat will replace part of process heat generated from the existing boiler. In this way, CH4 emission that would have accrued from the landfill, could be avoided and also CO2 emission that would have accrued from the existing coal fired boiler, could be reduced.

(Calculation)

1. The amount of CH4 emission from the municipal waste landfill EBCH4

EBCH4 = G ×f1 × f2 × f3 × 16/12 = 2,164.5 t-CH4/a, where

G =Amount of municipal waste to be incinerated by the AIJ project annually: 57,646 t-waste/a

f1 = the content of organic carbon in the municipal waste: 0.1788

f2 = ratio on gasification of organic carbon in landfill : 0.63

f3 = fraction of C as CH4 to C as bio-gas : 0.25

2. CO2 emission from the existing boilers (EBCO2)

E BCO2 = WB1 × C1 × Bf1 × 44/12 = 95,642.8 t-CO2/a, where

WB1= coal consumption in the existing boilers , which is estimated as average coal consumption of the boiler over the latest three years :

WB1= (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 (from Hegang coal mine) : 48.4 %

Bf1= the burning efficiency of the existing boiler : 86 %

(Results)

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

(1) CH4 emission

EBCH4 = 2,164.5 t-CH4/a

(2) CO2 emission

E BCO2 = 95,642.8 t-CO2/a

2) Estimated emissions with the activity(AIJ Project Case):

Description of the scenario, including methodologies applied:

(Concept)

Although IPCC Guideline suggests that CO2 emission caused by combusting biomass raw material should not be considered into net man-made CO2 emission, both Japanese and Chinese experts participating in the AIJ project agreed to keep two kinds of calculations at same time. One kind of calculations is made by following the IPCC guideline, and the CO2 emitted from the incineration of MSW is not taken into the net GHGs emission accrued from AIJ project.

The second kind is made according to the actual GHGs emission in the baseline and AIJ project, which is not following the IPCC guideline. The carbon balance is shown in Figure 2. The DOC(Degradable Organic Carbon) in the MSW can be divided into three parts, one part is not degraded in landfill, the second part is degraded and converted into CH4 emission and the third part is also degraded and converted into CO2 emission. When the AIJ project is implemented, all DOC is incinerated and converted into CO2 emission. Chinese side experts think it is more reasonable to estimate the emission according to the second kind methodology.

Image

Seven parts GHG emission from AIJ project are included:

  1. CH4 emission from the municipal waste in the landfill will be avoided by incinerating the municipal waste in the FBC boiler.
  2. CO2 emission from the existing coal fired boilers: The CO2 emission from existing coal fired boilers in the textile printing & dyeing works will be reduced, due to some coal substitution by municipal waste incineration for process heat.
  3. CO2 emission from additional electricity consumption necessary for operation of the municipal waste incineration: In the operation of the municipal waste incineration process additional electricity are demanded from power grid, that will make the net CO2 emission reduction smaller.
  4. CO2 emission from by incinerating man-made sources (plastics and chemical fabrics) in the municipal waste: during the waste incineration, some man-made origins, such as plastics and chemical fabrics, will also bring about CO2 emission that will make the net CO2 emission reduction smaller again.
  5. CO2 emission by combusting coal as auxiliary fuel at the municipal waste incineration plant in Summer season: Coal as auxiliary fuel will still be used during the Summer season, when the calorific value contained in the waste for incineration is not high enough to provide sufficient heat. Thus also lead to the net CO2 emission reduction smaller.
  6. CO2 emission from incinerating DOC(in the municipal waste) that is not degraded and being kept in landfill for the long term in the baseline case:
  7. CO2 emission from incinerating DOC(in the municipal waste) that originally forms CH4 in the landfill in the baseline case.

( = 78,201.7)

9. Total and CO2 emissions reduction against the baseline

To indicate the extent to which the CH4 emissions contribute to total radioactive forcing, we calculated its CO2-equivalent emissions in the baseline case by using the Global Warming Potential (GWP) values for a time horizon of 100 years taken, where reported, from the most recent IPCC assessment report (IPCC, 1996a). For CH4 the GWP =21.

(1) CH4 emission reduction (RCH4)

RCH4 = EBCH4 - EACH4 = 2,164.5 - 0 = 2,164.5 t-CH4/a

RCH4 (in CO2 equivalent) =2,164.5 × GWP = 45,454.5 ton-CO2

(2) CO2 emissions reduction (RCO2)

RCO2 = EBCO2 – EAIJCO2 = 95,642.8 - 98,137.3 = - 2,494.6 t-CO2/a

(78,201.6) (17,441.1)

Transfer of environmentally sound technologies and know-how Describe briefly

Transfer of Municipal Waste Incine-ration 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

By implementing the project, following capacity building can be attained:

  1. AIJ Project management
  2. Operation of the municipal waste incineration plant

3. Operation of the municipal waste collecting and transport system

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 demonstration project, dissemination activity of the technology through demonstration operation is planned in the final stage of overall project schedule. A larger 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 has been widely disseminated in Japan and enough practical and commercial experience has been already compiled, therefore the technology is highly reliable. For this reason, technical difficulty does not exist.

3) Negative impacts and/or effects encountered:

Suggestion on monitoring, verification and reporting of CO2 emission reduction in the project operation.

5.1. CO2 monitoring tasks

The overall task of the monitoring is to make the carbon balance monitoring within the entire system boundary of the project, in order to determining the real CO2 emission level and the corresponding CO2 emission reduction. So it can be done by the following monitoring tasks.

5.1.1. Energy balance monitoring

All energy consumed, including coal, electricity, steam, waste gas, for all process, including the municipal waste incineration, heat supply and electric supply, will be measured regularly, and the measuring data will be acquired and recorded during the project operation.

5.1.2. CO2 emission monitoring

Based on the energy efficiency and technical data available for those processes, the CO2 emission balance could be calculated or measured.

5.2 Baseline determination

Similarly, the CH4 and CO2 emission balance for the baseline case, i.e. in the municipal waste landfill case, should be measured or compared. In case some data are not available, some additional on-site surveys are required.

5.3 Personnel training

(1) The key staff member of the plant will be educated to enhance their public awareness on the CO2 emission mitigation, climate change and AIJ pilot phase under UNFCCC.

(2) The professional training will be done for the technical engineers and workers who will be involved in the monitoring tasks.

The training course could be given three months in advance of the plant’s commission.
