|Main Implementing Entity||Joint Venture of Mitsui Consultants and Japan Environmental Consultants|
|Study Partners||Carbon Finance Unit (CFU) of Ministry of Environment of Moldova, Japan Weather Association (JWA)|
|Location of Project/Activity||Moldova|
|Category of Project/Activity||Biomass Utilization|

|Description of Project/Activity||Many communities in poor rural and agricultural regions are experiencing difficulty securing a source of heating in the winter season due to the rising price of fossil fuels in Moldova. To respond this problem, Japan International Cooperation Agency (JICA) and United Nations Development Programme (UNDP) have begun a program to assist these communities in switching from fossil fuels such as coal to biomass fuel in Moldova. Straw-fired boilers funded by the Grant Aid for Grass-roots Human Security Project program of the Japanese Ministry of Foreign Affairs and the World Bank (WB) and pellet boilers funded by Moldova Social Investment Fund (MSIF) were selected as target facilities for this study. Green House Gas (GHG) emissions will be reduced by switching from fossil fuels such as coal to biomass fuel.|
|Eligibility Criteria||[Criteria 1]|
Fossil fuel used for boilers shall be replaced by biomass residues.
The project activity involves installation of (a) new boiler(s) to make energy use of biomass residue including biomass pellet for heat generation whose capacity is larger than 45 kW and energy efficiency is higher than 80%.
The biomass residue would otherwise be unutilized without the project activity.
The heat generated in the boiler would not be used for power generation.
|Reference Scenario and Project/Activity Boundary||Identified alternative scenario regarding how to handle generated heat and biomass residue and established the most appropriate reference scenario by barrier analysis.
Project boundaries are as follows.
|・ Without the project, existing boilers would continue to operate using the same fossil fuels.|
・ Without the project, biomass residue would be thrown away or left in a farm field to decompose under aerobic conditions or burned without management and not utilized for energy.
|・ GHG emissions related to operation of agricultural machinery to collect, bale, and transport biomass residue used for the project.|
・ GHG emissions related to the transportation of biomass burned in a boiler.
・ GHG emissions related to the operation of a pelletizing system (crushing, drying, pelletizing)
・ GHG emissions related to use of electricity or consumption of fossil fuel at the project site – e.g. use of a tractor to place biomass residue into a boiler, or a shredder for biomass residue. However, fossil fuels mixed with biomass is not included.
|Calculation Method Options||Four different calculation methods were prepared as follows.|
|1-1: Use heat meter to estimate reference emission. Use default values for emissions related to transportation process etc.|
|1-2: Use heat meter to estimate reference emission. Use project specific value for emission related to transportation process etc.|
|2-1: NOT use heat meter to estimate reference emission. Use default values for emission related to transportation process etc.|
|2-2: NOT use heat meter to estimate reference emission. Use project specific value for emission related to transportation process etc.|

- Boiler efficiencies
Existing boiler (values were provided by CFU)
0.92 (natural gas)
Straw boiler (based on manufacturer catalog)
0.81 (Hirtopul Mare G*)
0.80 (Hirtopul Mare K*)
0.815 (Viisoara G., Chiscareni L)
Biomass pellet boiler (based on manufacturer catalog)
0.86 (Moldagrotechnica, Fundurii Vechi Comminity Center and Balatina Community Center)
[*G=Gymnasium, K=Kindergarten, L=Lyceum]
Taking into account of variations in boiler efficiency caused by the operational variation of boilers, we adopted 0.5 as the correction factor of boiler efficiency and multiplied the boiler efficiency by the factor.
|Monitoring Method||Cumulative heat generated by a boiler (QBM,y)[GJ/yr]: Measured continuously via heat meter.|
Weight of biomass residue inputs (PCBM,y)[t/yr]: Count straw bales or pellet buckets fed into boiler after determining average bale weight or bucket weight of pellets.
|Result of Monitoring Activity||The monitoring period is divided into two periods. During the first monitoring period, outside temperature was higher than usual. For this reason, there were sites where boilers was operated only intermittently.
First Monitoring Period
|・Hirtopul Mare Gymnasium: November 27 - November 30, 2012|
・Hirtopul Mare Kindergarten: November 7 - November 30, 2012
・Viisoara Gymnasium: November 14 - November 30, 2012
・Chiscareni Lyceum & Gymnasium: November 14 - November 29, 2012
・Moldagrotehnica: November 8 - November 30, 2012
Second Monitoring Period
|・Hirtopul Mare Gymnasium: December 1, 2012 – January 23, 2013|
・Hirtopul Mare Kindergarten: December 1, 2012 – January 23, 2013
・Viisoara Gymnasium: December 1, 2012 – January 23, 2013

|GHG Emissions and its Reductions||Emission reductions based on second monitoring period data (unit: tCO2) |
Hirtopul Mare Kindergarten
[RE=Reference Emissions, PE=Project Emission, ER=Emission Reductions]
(2): Second monitoring period (54 days)
Yearly value: calculated by set the boiler annual operation date as 160 days.
|Method and Result of Verification||We entrusted the verification of the monitoring results to East-Europe Consulting Associates (EECA) and Rina Simtex Organismul de Certificare (Rina). As EECA had no experience of CDM related project, the outputs were not sufficient. On the other hand, Rina has experience enough to do the verification. Verifiers had commented on the monitoring reports prepared by CFU and all of them were solved with evidences provided by CFU.|
|Environmental Impacts||<Smoke Particulate Matter >|
Due consideration must be given to straw boiler smoke stack height and selection of boiler sites because there is a possibility that the concentration of smoke/particulate matter may exceed European Union (EU) standards. In the case of pellet boilers, environmental impact is minimum due to the provision of a dust collector.
Boiler ash is to be utilized as fertilizer in farm fields.
|Promotion of Japanese Technology||Establishment of a long-term fuel supply chain and maintenance service system will work to promote Japanese technologies. The supply chain and service system are both assisted and funded by JICA's Grant Aid project due to superiority of Japanese pellet boiler technology.|
|Sustainable Development in Host Country||

- Creation of new industry
- Job creation
- Positive economic impact of domestic investment as outbound currency flows are reduced
