SECTION A. General description of small-scale project activity

A.1        Title of the small-scale project activity:

Eiamburapa Company Ltd. Tapioca starch wastewater biogas extraction and utilization project, Sakaeo
Province, Kingdom of Thailand

Version 03
03 October 20081

A.2.       Description of the small-scale project activity:

The project activity, developed by Eiamburapa Company Ltd. (hereafter referred to as EBCL), involves
the installation of a closed anaerobic wastewater treatment and biogas extraction system at an existing
tapioca starch manufacturing plant in Sakaeo Province, Thailand. The project activity involves the
treatment of organic wastewater that would, in the baseline scenario, be treated in an open lagoon system.
The collected biogas is utilized for the generation of heat and electricity, to be used on-site. By capturing
and utilizing the biogas, the project activity reduces the amount of CH4 that would otherwise have been
emitted from the existing anaerobic open lagoons. The heat and electricity generated using biogas
displace fuel oil and electricity (sourced from the Thai national grid) that would otherwise be used in the
tapioca starch production process. This contributes to additional GHG emissions reduction.

The tapioca starch production facilities are currently capable of producing 500 tons of tapioca starch per
day, and the operation of these facilities results in approximately 7,000 m3/day of wastewater with high
organic content. In the baseline scenario, all wastewater from the production processes is treated at an
open anaerobic lagoon system and sprayed as a liquid fertilizer to neighboring farmlands. The open
anaerobic lagoon system meets the effluent regulatory standards for the tapioca industry in Thailand 2.

In the project activity, part of the organic wastewater (2,470 m3/day out of total 7,000 m3/day of
wastewater generated) from the plant is sent to anaerobic digesters prior to being discharged into the
existing open anaerobic lagoon treatment system. Anaerobic digestion consistently generates methane-
rich biogas. Generated biogas is collected and utilized for both heat and electricity generation. An open
flare system is installed in order to combust any excess biogas.

Biogas is used to fuel biogas heaters to provide the necessary heat to EBCL’s tapioca production process.
In order to utilize excess biogas, two biogas engine generators each with a capacity of 0.95 MW are
installed. The electricity generated is used to supply EBCL’s on-site energy needs, thereby displacing
electricity that would otherwise be imported from the Thai national grid.

        A.4.2. Type and category(ies) and technology/measure of the small-scale project activity:

(1)     Types and categories of the small-scale project activity

In accordance with Appendix B of the simplified modalities and procedures for small-scale CDM project
activities (“SSC M&P”), the proposed project falls under the following types and categories:

AMS-III.H
Type III        : Other project activities
Category H      : Methane recovery from wastewater treatment
Reference       : Version 9, Scope 13, in effect as of Mar. 28, 2008

AMS-I.C.
Type I          : Renewable energy projects
Category C      : Thermal energy for the user
Reference       : Version 13, Scope 1, in effect as of Mar. 28, 2008

AMS-I.D
Type I          : Renewable energy projects
Category D      : Electricity generation for a system
Reference       : Version 13, Scope 1, in effect as of Dec. 14, 2007

(2)     Technology of the small-scale project activity

UASB
The technology to be implemented by the project activity is an Upflow Anaerobic Sludge Blanket
(UASB) system, an anaerobic bioreactor technology developed originally in Europe. Papop Co., Ltd.
(PAPOP), a Thai engineering consulting firm working in the field of renewable energy and
environmental engineering, has designed and constructed the wastewater treatment system as well as the
biogas extraction system. Through the utilization of this advanced technology, the project is able to
achieve approximately 90% removal of COD, significantly reducing the COD load to the open lagoons,
which subsequently receive effluent from the UASB digester.

The wastewater that will be processed by the UASB is first pretreated by a pH adjustment pond to
stabilize pH to a suitable level. In the UASB process, wastewater flows upward through a sludge blanket
composed of microorganisms that naturally form granules or particles of 0.5 to 2 mm in diameter
(“sludge granules”). When wastewater comes in contact with the granules, anaerobic decomposition of
the organic material contained in the wastewater takes place, resulting in the generation of methane-rich
biogas. The hydraulic turbulence caused by produced biogas bubbles provides mixing to the digester.
The high sedimentation velocity of biological granules formed in the digester prevents washout of the
sludge granules, leading to longer sludge retention time in the digester.

A separator pond is used to divert excess wastewater that is surplus to the UASB system’s capacity. (In
the project activity the maximum wastewater flow rate from the tapioca starch processing facility
exceeds the capacity of the UASB system.) The excess wastewater will not be deemed to enter the
project boundary.

Sludge Disposal
PAPOP, the technology provider, states that in its experience to date 100% of sludge is recycled within
the UASB system and therefore there is no need for sludge disposal. In the event that surplus sludge is
generated it shall be disposed of in accordance with all applicable Thai waste treatment regulations.

Control & Instrumentation
Operation of the UASB is conducted through a SIMATIC digital SCADA (Supervisory Control & Data
Acquisition) system using a CPU model 313C-2 DP with 32 Kbyte RAM. The SCADA system is
designed by Siemens and will be operated by trained staff.

Biogas Heater
The biogas/fuel oil co-fired thermic fluid heaters are supplied by Scherrer, a well established German
manufacturer. The type 350 SI heaters are capable of running on either biogas or mineral fuel oil, and
have a maximum output of 3,250 Mcal/hr. Gas supply pressure range is 150-300 mbar.

Generator Set
Two electricity generators with installed capacity of 0.95 MW each are supplied by Guascor of Spain.
Guascor’s computerized module provides readouts of the condition of the spark plugs and allows to be
adjusted through external signals.

Flare System
As mentioned in the previous section, any excess amount of biogas is flared. For this activity, the
developer has installed a flaring system designed and manufactured by a local Thai company, Energy
Recovery Tech. The gas flow rate of the flare system has a range of 150-650 Nm3/hr at 30mBar, with a
combustion temperature of 700ºC. Flaring activity starts automatically when biogas reaches a high
pressure setting and stops automatically when biogas pressure drops to low pressure setting. The
combustion efficiency of the flare system is over 90% but for the sake of monitoring it shall be assumed
that the flare is an open type, with a combustion efficiency of 50%. This is a conservative assumption.

The effluent from the UASB system is further treated by the existing lagoon system and then applied to
neighbouring farmlands as a liquid fertilizer.

         A.4.4. Public funding of the small-scale project activity:

The project involves no ODA or public funding from Parties that are Annex I signatories to the Kyoto
Protocol.

        A.4.5. Confirmation that the small-scale project activity is not a debundled component of a
large scale project activity:

As defined in paragraph 2 of Appendix C of the SSC M&P, a proposed small-scale project activity shall
be deemed to be a debundled component of a large project activity if there is a register small-scale CDM
project activity or a request for registration by another small-scale project activity:

     By the same project participants;
     In the same project category and technology/measure;
     Registered within the previous 2 years; and
     Whose project boundary is within 1 km of the project boundary of the proposed small-scale activity
      at the closest point.

The proposed project activity is not a debundled component of any larger project activity as there is no
other small-scale project activity that fulfils the abovementioned criteria.

      The physical, geographical site of the renewable energy generation delineates the project boundary;
      The physical, geographical site of the renewable generation source; and
      The physical, geographical site where the wastewater and sludge treatment takes place.


B.4.      Description of baseline and its development:


Base line determination for wastewater treatment
For the wastewater treatment system, the baseline is described in paragraph 23(vi) of AMS-III.H. as
being the existing anaerobic wastewater treatment system without methane recovery. In the Project’s case,
the existing system is a sequence of 9 open anaerobic lagoons.
Baseline determination for heat displacement
The appropriate baseline for the projects applying AMS-I.C. is the fuel consumption of the technologies
that would have been used in the absence of the project activity times an emission coefficient for the
fossil fuel displaced as stipulated in paragraph 6 of the methodology. Therefore, the baseline for the heat
displacement component of the project activity is the continuation of the usage of fuel oil to meet the
energy demand of tapioca production.

Baseline determination for electricity generation
The electricity baseline is determined in line with paragraph 9 (a) of AMS-I.D., i.e. a combined margin
(CM), consisting of the combination of operating margin (OM) and build margin (BM), according to the
procedures prescribed in the “Tool to calculate the emission factor for an electricity system”.


B.5.    Description of how the anthropogenic emissions of GHG by sources are reduced below
those that would have occurred in the absence of the registered small-scale CDM project activity:

In line with Attachment A to Appendix B of the simplified modalities and procedures for small-scale
CDM project activities, the Project is deemed to be additional because it faces the following barriers:

(b)    Technological barrier
(c)    Barrier due to prevailing practice

Technological barrier
Anaerobic bioreactor and biogas utilization technology is not yet widespread and is considered as a high
risk with a limited performance guarantee in Thailand. Local peculiarities associated with tapioca’s
wastewater acidity, sediment content and COD quality cause operational problems which stall production
and/or lower the biogas yield which directly affects the feasibility of the project activity. There is still a
dearth of skills and labor necessary to operationalize and maintain new wastewater treatment systems
properly. In particular initiating and maintaining the anaerobic reaction within the UASB through the
recycling of sludge granules requires expert knowledge and is fraught with uncertainty. Specialist
training in online SCADA technology, which is still relatively unknown in Thailand, is also required.

In summation there are significant performance and technology risks in anaerobic effluent treatment
which deter domestic firms from attempting it.

Korat Waste to Energy Project, which became the first Thai wastewater CDM project to register in June
2007, began its initial attempt toward acquiring CDM status in 2002 and submitted their new
methodology (NM0041) in early 2004. Since then, knowledge of the CDM became widespread among
tapioca starch owners in Korat and the surrounding area in Thailand. It triggered various tapioca starch
plant operators in Thailand to start look into anaerobic bioreactor and biogas utilization technologies as
an investment option with the aim of generating revenue from CERs and use this additional revenue to
overcome the technological risks mentioned earlier.

Likewise, the project developer, EBCL and SC, expects to overcome the above mentioned technological
barrier by utilizing CDM revenue to install more reliable equipment and provide necessary technology
training to their staff which is necessary for the optimum operation of the project activity.

Barrier due to prevailing practice
Treatment using an open lagoon system has historically been the common way of handling wastewater
from tapioca starch production in Thailand. According to the Thai Tapioca Starch Association (TTSA),
currently there are 80 tapioca production facilities in Thailand. Out of those 80 projects, 1 was registered
with the UNFCCC, 15 were approved by the Thai DNA and 17 have submitted the application to the
Thai DNA3. The majority of these projects have been materialized within the past three years, which
indicates that the project owners became aware of the CDM benefit and positive environmental impacts
that the biogas technology could bring in. This became more firm after the first successful CDM
registration of Korat Waste to Energy project on June 16, 2007. This information suggests that the CDM
incentive has been a major deciding factor for many of the tapioca plant owners to invest in anaerobic
digester and biogas utilization technology.

As the starting date of the project activity falls before the starting date of the validation, evidence is to be
provided to show that the incentive from the CDM was seriously considered in the decision to proceed
with the project activity.

In accordance with “Guidance on the demonstration and assessment of prior consideration of the CDM”,
the table below demonstrates the serious prior consideration of the CDM by the project participants. As
indicated below continuing real actions have been taken by the project participants to secure CDM status
for the project activity.

B.6.         Emission reductions:

           B.6.1. Explanation of methodological choices:

Emission reductions associated with wastewater treatment

The baseline scenario for wastewater treatment is the existing anaerobic lagoon system without methane
recovery corresponding to (vi) of paragraph 1 of AMS-III.H.version09.

The emission reduction due to the wastewater treatment (ERy,ww) is calculated as the difference between
the baseline emission from wastewater (BEy,ww) and the sum of the project emissions (PE,y,ww) and
leakage (LEy,ww).

ER y , ww  BE y , ww PE y , ww  LE y , ww                                                            III.H./ver09 (28)

Where

PE y , ww  PE y , power  PE y , ww,treated  PE y , s , final  PE y , fugitive  PE y , disolved       III.H./ver09 (1)

PEy,power                      = emissions from electricity or diesel consumption in year y
PEy,ww,treated                 = emission through degradable organic carbon in treated wastewater in year y
PEy,s,final                    = methane emissions from the anaerobic decay of the final sludge generated in the
                               wastewater system in year y
PEy,fugitive                   = emissions from methane release in capture and flare systems in year y
PEy,dissolved                  = emissions from dissolved methane in treated wastewater in year y

As the project activity does not use the technology transferred from or to another activity, the leakage
effects of transportation are not counted.

Emission reductions associated with heat displacement

In accordance with AMS-I.C., the heat baseline is the fuel consumption of the technologies that would
have been used in the absence of the project activity times an emission coefficient for the fossil fuel
displaced. The emission reductions due to the heat displacement (ERy,heat) is calculated as per the
following table.

Emission reductions associated with electricity displacement

The baseline for power generation is the kWh produced by the renewable generating unit multiplied by
an emission coefficient (measured in kgCO2e/kWh) calculated in a transparent and conservative manner
as a combined margin (CM), consisting of the combination of operating margin (OM) and build margin
(BM) according to the procedures prescribed in the “Tool to calculate the emission factor for an
electricity system (version 01.1)” (hereafter referred to as “Tool”).

                 (tCO2/MWh)

Step 1. Identify the relevant electric power system

As per the Tool, a project electricity system is defined by the spatial extent of the power plants that are
physically connected through transmission and distribution lines to the project activity and that can be
dispatched without significant transmission constraints.

Since there is no layer dispatch system and DNA guidance on delineation of grid boundaries available in
Thailand, for the project activity, the grid boundary system is defined at the national level.

Step 2. Select an operating margin (OM) method

The Tool offers four options for the calculation of OM: (a) Simple OM, (b), Simple adjusted OM, (c)
Dispatch Data Analysis, or (d) Average OM. Since EGAT’s low-cost/must run resources constitute less
than 50% of the total grid generation and no dispatch data is available to conduct Dispatch Data Analysis,
option (a) Simple OM method was chosen.

The ex-ante option was selected for the Project.

Step 3. Calculate the operating margin emission factor according to the selected method (OM)

The simple OM method as selected in Step 2 above is calculated as the generation-weighted average CO2
emissions per unit net electricity generation of all generating power plants serving the system, not
including low-cost/must-run power plants/units. The Tool provides the following three approaches to
calculate the simple OM.

Option A:       Based on data on fuel consumption and net electricity generation of each power
                plant/unit, or

Option B:       Based on data on net electricity generation, the average efficiency of each power unit and
                the fuel type(s) used in each power unit, or

Option C:       Based on data on the total net electricity generation of all power plants serving the
                system and the fuel types and total fuel consumption of the project electricity system.


Calculation using Option A, while being the preferred methodological choice, is not feasible as no data
on net electricity generation of each power plant is officially made available by EGAT. Option B is also
ruled out as data on the average efficiency of each power unit and the fuel type used in each power unit is
not officially available. In the Thai grid, only hydro power is considered as low-cost/must-run power
sources. There is a plan to build four nuclear power plants in the next 14 years but there is no active

OM calculation method.

                              plants/units, in year y

Step 4. Identify the cohort of power units to be included in the build margin (BM)

The build margin is calculated as the generation-weighted average emission factor of a sample of power
plants. As per the Tool, the sample group to calculate BM consists of either:

(a) The set of five power units that have been built most recently, or
(b) The set of power capacity additions in the electricity system that comprise 20% of the system
    generation (in MWh) and that have been built most recently.

According to the data obtained from the Department of Alternative Energy Development and Efficiency
(DEDE)5, 20% of the total grid generation of the Thai grid represents a larger amount of generation than
that of the five most recently built power plants. The table provided in Annex 3 of this PDD shows the
data for recent power plant capacity additions that comprises 20% of the system generation

The power plants capacity built prior to the most recent five is added in reverse chronological order until
the value equivalent to 20% of the total generation is reached. Detail data for the BM is provided in
Annex 3.

The ex-ante calculation option was chosen.

Step 5. Calculate the build margin emission factor

The build margin emissions factor is the generation-weighted average emission factor (tCO2/MWh) of all
power units during the most recent year for which generation data is available, calculated as follows:

Project emissions

(a) Project emissions from electricity or diesel consumption (PEy,power)

It is expected approximately 415 MWh of electricity will be consumed by the equipment installed as part
of the project activity. As stipulated in AMS-III.H. paragraph 13, the emission factor for this electricity
consumption is set to zero because the recovered methane is used to power auxiliary project equipment.
Project emissions associated with electricity consumption are calculated as follows;

PE y , power  415MWh  0tCO 2e / MWh
         0 tCO 2 / year

No diesel consumption is expected in the Project, and is not estimated ex-ante.

However, any additional consumption of either electricity or diesel associated with the project activity
will be monitored as they arise and calculated ex-post.

A comprehensive Thai-language monitoring manual is being developed for use at EBCL and will be in
place by the start of the crediting period. The CDM monitoring manual, in conjunction with this PDD,
will be the definitive reference source for monitoring the project activity during the crediting period. All
monitoring equipment will be installed by experts and regularly calibrated to the highest standards by
EBCL. EBCL will form a team to maintain and operate the project activity and monitor the parameters
required by the methodology. The team will be composed of a plant manager, a Production/Biogas plant
supervisor, a Genset/biogas heater supervisor and operational staff. Figure 3 outlines the structure of
operation and management of the project activity.

SECTION D. Environmental impacts

D.1.    If required by the host Party, documentation on the analysis of the environmental impacts
of the project activity:

Thai law mandates all CDM projects which are submitted to Thai DNA approval process to conduct an
Initial Environmental Evaluation (IEE) and prove no adverse environmental impact results from
implementation of the project activity. To this end EBCL has commissioned a survey as to the possibility
of any environmental impact, and it has been confirmed that the project activity results in no ill effects.
The IEE, conducted by Advanced Energy Plus - an energy and environmental consultancy firm based in
Bangkok - concluded the following:

CDM – Executive Board




        Impact assessment of the new wastewater treatment operation compared with the old
        system operation shows a satisfactory result. Most environmental aspects are actually
        expected to improve after implementing the UASB system. Only gas safety will have
        negative impacts compared to the anaerobic lagoons, but such impacts is not significant
        as explained before, and mitigations measures are, therefore, not required except for
        putting up an appropriate warning sign. All staff working at the biogas plant should also
        receive adequate training on fire safety. In addition, the starch plant shall supply
        sufficient fire fighting equipment located within the gas storage area and maintain them in
        good condition.6

EBCL shall comply with the recommendations provided in the IEE and provide adequate equipment and
staff training to ensure fire safety.

Thai law does not require an Environmental Impact Assessment (EIA) for implementation of project
activity. However, the expected environmental impact of the project activity was considered thoroughly
prior to the project implementation. It is found that the project activity in fact has rather positive impact
to the neighboring environment as well as to the overall health of the neighboring residents. As the result
of the project activity an advanced wastewater treatment technology is introduced. Water quality flowing
into the existing lagoons is improved significantly and the risk of pathogenic organisms proliferating in
the water body is significantly reduced. Moreover, the strong odor resulting from decomposition of
organic materials in the wastewater will be minimized.


D.2.    If environmental impacts are considered significant by the project participants or the host
Party, please provide conclusions and all references to support documentation of an environmental
impact assessment undertaken in accordance with the procedures as required by the host Party:

As described above, no significant adverse environmental impacts are expected to result from the project
activity.

impact of the project, and to share opinions. EBCL was represented by their staff, and the CDM project
developer was represented by Advance Energy Plus Co., Ltd. The technology supplier and CDM experts
were also present, to answer the questions regarding the biogas technology and CDM-related issues
respectively.


E.2.    Summary of the comments received:

The main comments received concerned two main issues: volume and odour of wastewater and safety.
The comments and questions of the participants are summarized below:

Q: What is the maximum capacity of the biogas plant?
A: According the design figure, the flow rate of the influent entering to biogas system is 2,500 m 3 per
   day, however the wastewater volume can be increased to 120% of the design capacity which is
   around 3,000 m3/day

Q: What is the portion of wastewater that be reused in the starch plant?
A: Eiamburapa re-uses the waste water from the last pond for washing process around 500 m3/day

Q: What is the retention time of wastewater in the acid pond?
A: The retention time in the acid pond is 2 days. Acid pond had constructed with concrete and coated
   with acid resistance substance to ensure that there is no leakage in this pond

Q: Before start up the biogas plant, do you test the safety equipment? After start up, do you check these
   safety equipments?
A: This question answer by biogas supplier, before start up, all safety equipment will be tested to
   confirm that all equipments can work properly. We also have to maintenance all of the equipments
   according to supplier manual.

Q: Can existing open lagoon receive all of wastewater form the starch plant during the rainy season?
A: Yes, sure. The existing open lagoon can receive all of wastewater from the starch plant. The
   wastewater from the last pond will be reused in the plant and also be given to the farmer for
   plantation.

Q: Do you test the quality of wastewater from the last pond?
A: Yes, we usually test the wastewater from the last pond by our own lab.

Q: Where is the raw water uses in the starch plant come from?
A: Raw water comes from the natural river and we also have raw water collecting pond near the starch
   plant.

E.3.    Report on how due account was taken of any comments received:

At the beginning of the meeting, the project developers explained the complete details of the project to
the participants. The key benefits from the biogas plant (reduced air and water pollution, and reduced
foul smell compared to the existing open lagoon system) were also explained, which the participants
understood well. There was hence no serious comment on the environmental impacts or safety aspects.

None of the participants had a negative view of the project.

Grid CEF calculations

As instructed in the methodology, Thai grid CEF was calculated based on AMS-I.D. because the installed
capacity of the project is less than 15 MW.

Based on AMS-I.D., a combined margin (CM), consisting of combination of operating margin (OM) and
build margin (BM) according to the procedures prescribed in the “Tool to calculate the emission factor
for an electricity system” was calculated for Thai national grid.

The data sources used for the grid emission factor are as follows:

- EPPO: EGAT grid generation & fuel consumption 2005-2007
http://www.eppo.go.th/power/data/data_website_spp.xls

- DEDE: Generation and fuel consumption of recently built plants 2006
http://www.eppo.go.th/power/data/data_website_spp.xls

- DEDE: Energy content of fuel (Net calorific value) 2006
http://www.dede.go.th/dede/fileadmin/usr/wpd/static/thail_ele_2006/54CONVERS.pdf

-   EGAT Power Development Plan 20047

 Used to estimate power generation from individual build margin SPPs where more recent data is unavailable. Where fuel
consumption for SPPs is unknown, emissions are conservatively assumed to equal zero

What is Green House Gas effect and what is CDM or Clean Development Mechanism? In our daily life,
people have many activities that produce Carbon Dioxide (CO2). The CO2 which is released to the
atmosphere causes the atmospheric temperature to rise, which is called the greenhouse effect. In the 1997
Kyoto Protocol (a part of the United Nations agreement), a number of nations reached an agreement to
reduce the emissions of greenhouse gases in to the atmosphere. As per the agreement, some countries are
obliged to reduce the emission of greenhouse gases over the coming several years. These are called
Annex I countries, which include Europe, North America, other OECD nations, the former Soviet Union
and Eastern Europe. To allow them to do this, a flexible mechanism called Clean Development
Mechanism (CDM) was introduced. CDM permits the activities to be undertaken in non-Annex I
countries. The CDM will allow Annex 1 countries to develop projects in non-Annex 1 countries, which
will reduce greenhouse gas emission. EIAMBURAPA project is developed as one of such projects in
Thailand. The gases that are defined as greenhouse gases are:
       Carbon Dioxide (CO2)
       Methane (CH4)
       Nitrous Oxide (N2O)
       Hydro fluorocarbons (HFCs)
       Per fluorocarbons (PFCs) and
       Sulphur Hexafluoride (SF6)

The actual issuance of the credits or CERs (Certified Emission Reductions) is made by the CDM
Executive Committee of the United Nations.


(ii) How the EIAMBURAPA project is related to CDM and how the project can reduce greenhouse
gases?

What will happen when the wastewater flows through the open lagoon? The bacteria in the lagoon act
upon and digest the organic materials in the wastewater. Aerobic digestion takes place on the surface of
the lagoon while anaerobic digestion takes place beneath the surface. Anaerobic digestion reaction will
generate Biogas which is composed of methane (CH4), carbon dioxide (CO2) and Hydrogen Sulphide
(H2S) gases. The biogas has a heating value of approximately 9,000 kcal/ m3; therefore 1 m3 of biogas
can generate electricity 1.85 kWh or replace 0.6 litre of bunker oil, 0.5 litre of gasoline, 0.6 kg of LPG,
1.9 kg of rice husk as fuel. In the process of treating wastewater through the open lagoons, there are two
issues. One is the natural discharge of biogas from the pond system, which will be considered as GHGs,
into the atmosphere. This is a naturally occurring by-product of organic decomposition. The second is
the odour from the biogas that is immediately apparent as a result of aeration.

New wastewater treatment system based on Upflow Anaerobic Sludge Blanket (UASB), which is closed
system, where the gas generated in the process is not allowed to escape. Biogas is collected and replace
fuel oil at boiler. The amount of GHGs reduction from the project activities will be considered as
Certified Emission Reductions (CERs) which could be registered under CDM activity.

Eiamburapa Co., Ltd. (EIAMBURAPA) has the capacity approximated to 500 tons of native starch per
day and has wastewater generated from the starch plant around 4,000 m3 per day.

To tackle the wastewater issues, EIAMBURAPA has decided to construct a new wastewater treatment
system based on Upflow Anaerobic Sludge Blanket (UASB) system. This technology will use anaerobic
bacteria to digest the organic materials in the wastewater. The system will use bacteria that already exist
in the wastewater in a natural biological process. We can see this process occurring in all wastewater
ponds, animal farms and kitchens where food is allowed to decay. The UASB system is a closed system.
Biogas is collected and then used as a fuel to replace fuel oil at heating generation equipment for starch
plant

The UASB system has a number of benefits: it reduces the release of methane (which is one of the
GHGs) into the atmosphere; generates biogas as a by product (which can be used as a fuel in the plant);
and maximizes the conversion of organic material into biogas, thereby accelerating the digestion process.
The technology has a high reliability and requires low maintenance.

The environmental effects of the UASB system are very beneficial: cleaner wastewater within a shorter
period of time; no odour; no leakage of wastewater to the ground water

Thank you everyone and if anybody has any questions, please feel free to ask.

Summary of comments received during forum:

Q & A session was announced at the event, where questions were invited from the related parties. The
questions were basically answered by the AEP and EIAMBURAPA. The questions and answers are
listed in the following sections:

Q: What is the maximum capacity of the biogas plant?
A: According the design figure, the flow rate of the influent entering to biogas system is 2,500 m 3 per
   day, however the wastewater volume can be increased to 120% of the design capacity which is
   around 3,000 m3/day

Q: What is the portion of wastewater that be reused in the starch plant?
A: Eiamburapa re-uses the waste water from the last pond for washing process around 500 m3/day

Q: What is the retention time of wastewater in the acid pond?
A: The retention time in the acid pond is 2 days. Acid pond had constructed with concrete and coated
   with acid resistance substance to ensure that there is no leakage in this pond

Q: Before start up the biogas plant, do you test the safety equipment? After start up, do you check these
   safety equipments?
A: This question answer by biogas supplier, before start up, all safety equipment will be tested to
   confirm that all equipments can work properly. We also have to maintenance all of the equipments
   according to supplier manual.

Q: Can existing open lagoon receive all of wastewater form the starch plant during the rainy season?

A: Yes, sure. The existing open lagoon can receive all of wastewater from the starch plant. The
   wastewater from the last pond will be reused in the plant and also be given to the farmer for
   plantation.

Q: Do you test the quality of wastewater from the last pond?
A: Yes, we usually test the wastewater from the last pond by our own lab.

Q: Where is the raw water uses in the starch plant come from?
A: Raw water comes from the natural river and we also have raw water collecting pond near the starch
   plant.
