SECTION A. General description of small-scale project activity

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

Lean Biogas recovery from Palm Oil Mill Effluent (POME) ponds and biogas / biomass utilisation at

Exportadora del Atlántico, Lean/Honduras.

Version of the Document: 1

Date: December 18, 2007

A.2.

Description of the small-scale project activity:

Exportadora del Atlántico Lean is devoted to the extraction and refining of palm oil. Apart from the oil

press, its facilities include diverse industrial processes: Refining, fractionation, interesterification

process, biodiesel production and a fat and oil production plant. The Palm Oil Extraction Plant consumes

approx. 2,500 MWh/yr of electricity from the grid. The liquid effluents generated due to the fruit

processing amount to approx. 123,000 m

3

/year (year 2008), with a Chemical Oxygen Demand (COD)

load of approx. 8,000 t/year

1

. These effluents are presently led to a treatment system that consists of a set

of fat traps and 15 open lagoons. In these lagoons, anaerobic processes take place, which generate biogas

that is currently being emitted to the atmosphere. After passing the lagoons, the waste water is discharged

to a nearby river.

The planned CDM project activity will optimise the existing treatment system. The biogas will be

collected and used to generate electricity, which will partially be exported to the grid and partially be

used in the Palm Oil Extraction Plant. For doing so, a new biogas generator (two container units of

750 kW each) will be constructed.

To summarize, the project reduces greenhouse gas emissions (GHG) in the following ways:

by preventing methane emission through biogas capture,

by replacing electricity consumption from the grid by utilizing biogas, and

by replacing electricity consumption from the grid by utilizing biogas.

Contribution to sustainable development:

Besides reducing GHG emissions and helping to reduce Honduras’ dependence on fossil fuels, the

planned CDM project activity will improve the quality of the discharged water significantly by removing

organic matter from the effluent and by minimizing water pollutants such as oils, greases and particles.

Honduras has defined several indicators for sustainable development contributions

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

Categories and type of the planned CDM project activity:

The project activity belongs to the following categories as listed in the sectoral scopes

for accreditation

of the operational entities (http://cdm.unfccc.int/DOE/scopes.html):

Sectoral scope 13:

Waste handling and disposal.

Sectoral scope 1:

Energy industries (renewable- / non-renewable sources)

The project activity includes Type III (methane recovery) and Type I (electricity generation) elements of

the Small Scale CDM project categorisation.

Technology / measure of the planned CDM project activity:

1. Methane capture:

Currently, Lean’s wastewater treatment system consists of:

a 5-tank-recovery system for palm oil from the effluents from the centrifuges, grease traps, and

a set of 15 open lagoons, whose characteristics are shown in Figure 1. Without considering the

grease traps, the system has a total lagoon volume of approximately 56,000 m

3

. The average

depth of the anaerobic lagoons 1-8 is 2.66 m; the average depth of the whole system is 2 m.

Figure 1: Current lagoon system at Lean.

(8)

incompacted clay and high density polyethylene geomembrane. The covered lagoons will have a volume

of 2 x 7,500 m

3

and are expected to remove approximately 90% of the COD-load in the effluents.

Besides this, the following technical components will be constructed:

Component

Function and description

Cooling towers

Two operating units in parallel, used for reducing the temperature of

the affluent from 70

°

C to 40

°

C. With vertical flux, fed by encased

centrifugal pumps and stainless steel impeller.

Lagoon

impermeabilisation

HDPE geomembrane to avoid infiltrations (organic load losses),

phreatic water dilution, and pollution of possible subsurface water

bodies.

Sludge agitation and

drainage system

To mix and recirculate the sedimented sludge in both anaerobic

lagoons. Recirculating the sludges helps to digest them, and mixing

them prevents the filling up of the lagoons through sedimented sludge

compactation.

Auxiliary transformers

and electric system for

pumps and engines

Two units (approx. 150 kVA and 50 kVA) for feeding two engine load

centres in the anaerobic and facultative lagoons, respectively.

Lagoon covering

The cover for the lagoons will be made in flexible plastic material,

resistant to gas and weathering, and equipped with a system for

evacuating the rainwater that deposits in the surface. The cover surface

for each lagoon is approx. 4,000 m

3

.

Biogas blowers

Transport of biogas; for a capacity of 900 m

3

/hour.

Biogas conduction

For a maximum daily flow of 900 m

3

/h, a conduction of 150 m is

projected, in PVC of 6” or 8” diameter. The system includes water

traps for the condensed water and various sampling points.

Biogas purification filters

The crude biogas contains approximately 0.2% (2,000 ppm) H2S. The

system considers a biologic depuration of this H2S, by means of

Thiobacillus bacteria. The depuration system consists of two parallel

sets for reducing H2S from 2,000 ppm (when leaving the lagoons) to

200 ppm. It also acts as humidity condenser.

Emergency generator

50 kVA diesel unit for the operation and starting of the system in case

of grid energy failures.

Flare

It is used for burning the excess biogas that cannot be used in any of

the components of the system, either for over-production or during

maintenance operations. The flare is open, with a flame trap and a

temperature flame detector.

Monitoring equipment and

instrumentation (SCADA

system)

Pressure meters (in “U” and electronic), biogas caudal meter,

thermometers (for effluents and biogas), pH-meters for the effluent,

contact sensors for the valves, biogas analyser (CH4, CO2, O2, H2S),

time meter in the press (extractor), blowers, compressors, cooling

tower vents, pumps, temperature flame detector. Includes PLC and

monitoring and reporting software located in control shack.

The technology will be provided Bio-Tech, a Belgium technology provider (also see section B.5 of this

document).

(9)

2. Renewable electricity generation:

A generator-system will be installed as an enclosed unit (40 feet container). This unit will comprise a

piston engine-generator, electric displays, radiators, oil tanks, electric control and power displays and

PLC. The new system will have an installed capacity of 1,500 kW (two units with 750 kW each). In

addition, a transformator (100kVA) and necessary interconnections to the electricity grid and on-site

demand point will be installed.

A.4.3 Estimated amount of emission reductions over the chosen crediting period:

Year Annual estim ation of emission reduc tions

[tons CO_{2 e}] 1 (2008/2009) 26,855 2 (2009/2010) 26,588 3 (2010/2011) 26,052 4 (2011/2012) 25,660 5 (2012/2013) 25,071 6 (2013/2014) 24,750 7 (2014/2015) 23,644

Total estimated reductions

[tons CO_2e] _178,620

Total number of crediting ye ars 7

Annual average ove r the crediting period of estimated reductions [tons

CO_2e] _25,517

It may be noted that the decrease of emission reductions over time is due to increased production in the

Palm Oil Plant (due to increased harvest from palms according to the natural growth cycle) and

responding increase of wastewater volumes.

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

Neither public funding nor official development assistance are used in the project activity. No loans from

international financial institutions (IFIs) are included. The financing will be realized by Exportadora del

Atlántico with a bank loan and the sale of generated CERs.

(10)

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

large scale project activity:

According to the CDM-regulations, a small-scale project activity shall be deemed to be a debundled

component of a large project activity if there is a registered small-scale CDM project activity or an

application to register another small-scale CDM project activity if all of the below conditions are

fulfilled:

Same project participants;

Same project category and technology/measure;

Registered within the previous 2 years; and

Project boundary is within 1 km of the project boundary of the proposed small-scale activity at

the closest point.

While there is another project seeking registration as a Small Scale CDM project by the same project

participants

3

, the project cannot be considered as a debundled component of a larger project because the

project is located 165 km from the proposed project boundaries and thus is not within the above

mentioned range.

SECTION B. Application of a baseline and monitoring methodology

B.1.

Title and reference of the approved baseline and monitoring methodology applied to the

small-scale project activity:

1. Methane capture:

Approved Small Scale Methodology AMS III.H “Methane recovery in waste water treatment”,

Version 08, as of December 14

th

, 2007 is applied.

2. Renewable electricity generation:

Approved Small Scale Methodology AMS I.D “Renewable Energy Generation for the Grid”,

Version 13 as of December 14

th

, 2007 is applied. It refers to the “Tool to calculate the emission

factor for an electricity system” (Version 01).

B.2 Justification of the choice of the project category:

1. Methane capture:

The project activity fulfils the eligibility criteria of AMS III.H, as it complies with option (iv):

“Introduction of methane recovery and combustion to an existing anaerobic wastewater treatment

system such as anaerobic reactor, lagoon, septic tank or an on site industrial plant.

” The adaptation of

some of the existing lagoons as described in section A.4.3 has a similar purpose and effect as the

3

Aguan biogas recovery from Palm Oil Mill Effluent (POME) ponds and biogas / biomass utilisation at Exportadora del Atlántico, Aguan/Honduras.

(11)

construction of an anaerobic tank digester, as biogas emitted from the wastewater system will be

captured. In addition, resulting emission reductions are less than 60kt of CO2 per annum.

AMS III.H also specifies that a project activity can use a corresponding category under type I, if the

recovered methane is used for heat and or electricity generation. The latter is the case, and hence

AMS I.D will be applied in combination with the „Tool to calculate the emission factor for an electricity

system“.

2. Renewable electricity generation:

The project activity fulfils the eligibility criteria of AMS I.D, as a new renewable biomass plant will

supply electricity to and/or displace electricity from an electricity distribution system that is or would

have been supplied by at least one fossil fuel fired generating unit: the system will be connected to the

interconnected system of Honduras (managed by the national electricity provider ENEE) that is fed by

several fossil-fuel fired plants – also see Annex 3 of this document. In addition, the units added by the

CDM project activity are lower than 15 MW and are physically distinct from the existing units at the

project site.

B.3.

Description of the project boundary:

1. Methane capture:

AMS III.H specifies the project boundary as “the physical, geographical site where the wastewater and

sludge treatment takes place”. Included gases are CO2 and CH4. Emission sources are the untreated and

treated wastewater, final sludge, power consuming project activity facilities, the flare system, and treated

waste water effluent.

2. Renewable electricity generation:

AMS I.D specifies the project boundary as “

The physical, geographical site of the renewable energy

generation”. The i

ncluded gas is CO2. Emission sources are the technologies and/or fuels that would have

been used for power generation in the absence of the CDM project activity.

The project boundary is visualised in Figure 2.

(12)

Figure 2: Project boundaries of the planned CDM project activity.

B.4 .

Description of baseline and its development:

1. Methane capture (AMS III.H)

Honduran legislation does not require the capture of biogas from industrial waste water treatment

systems, nor is there any such legislation concerning the treatment of liquid or sludge by-products

produced through industrial activities. On the contrary, open lagoons have a low operational risk and are

the cheapest solution for the treatment of wastewater with regard to initial investments and operating

costs.

Since there is no applicable legislation for the capture of biogas, the baseline scenario can be identified

as continued operation of the existing wastewater treatment system – i.e. a situation in which methane

emissions from anaerobic processes are released to the atmosphere. The project activity will reduce

greenhouse gas emissions through the collection of biogas and thermal destruction of methane.

Project activity emissions consist of:

CO2 emissions on account of power used by the project activity facilities.

Methane emissions on account of inefficiency of the wastewater treatment and presence of

degradable organic carbon in treated wastewater;

Methane emissions from the decay of the final sludge generated by the treatment systems;

Methane fugitive emissions on account of inefficiencies in capture and flare systems;

Methane emissions resulting from dissolved methane in the treated wastewater effluent.

As no bottling of upgraded biogas occurs, these sections of AMS III.H do not apply and are neglected.

(13)

2. Renewable electricity generation (AMS I.D)

The baseline scenario - both for on-site electricity consumption and electricity export to the grid - is that

the respective amount of electricity would have been generated by power plants connected to the national

electricity grid. Hence, the baseline is

the amount of electricity produced by the renewable generating unit

(MWh) multiplied by an emission coefficient (kg CO2e/MWh). This grid emissions factor is calculated in a

transparent and conservative manner as the combined margin as specified in the „Tool to calculate the

emission factor for an electricity system“.

Again, there is no legislation in Honduras that prescribes using renewable energy sources for electricity

generation

Data has been taken from the installations’ planning (technical feasibility study conducted by Biotech)

and production forecasts of the Palm Oil Mill (data provided by the project owner). Values for COD are

based on measurements (external lab-test); done in November 2006. As a conservative estimate, the

lowest measurement result has been taken as the basis for emission reduction calculations. - The

production of fresh fruit decreases over time due to the natural growth of the palm plants.

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:

Attachment A to Annex B of the simplified modalities and procedures for CDM small-scale project

activities specifies that a project activity would not have occurred anyway if it faces at least one of the

following barriers: investment barrier, technological barrier, barrier due to prevailing practice, or other

barriers. The project activity faces several barriers, which are summarised in the following paragraphs:

1) Investment barrier:

The financial implementation of the planned CDM project activity is a challenging task – both in terms

of the project’s economics and the financing of the installations.

4

There are some financial incentives for renewable electricity generation (specified in Decree 85-98, Incentives for the generation of renewable energy; Decree 267-98 for the use of renewable and natural resources to generate electricity; Decree 176-99 and Decree 267-98 from the Law of Renewable Incentives; Decree 103-2003 concerning

(14)

1a) Economic attractiveness of the investment:

Honduras suffers from weak local economy and local banks charge high interest rates. From January

2006 to February 2007, i.e. the period in which the initial feasibility study was conducted and the

investment decision was made, average interest rates for loans based in Lempiras ranged from 16.4% to

18.4 %, with an average of 17.4% (

www.bch.hn

). The maximum allowable interest rates during the same

period were even 27.6% to 33.7%

5

. Hence, any investment financed by bank loans needs to have an

IRR higher than at least 17.4%

(conservative estimate) in order to be economically attractive

to an investor. This does not even consider risks associated with a project activity.

Without considering revenues from sales, the project-IRR without considering revenues from

CER-sales is significantly below these levels. The IRR has been calculated for several scenarios:

a “standard scenario” with constant electricity prices,

a scenario in which electricity prices increase by 10%

a scenario in which prices for electricity decrease by 10%

The results of the calculations are summarised in the following table; detailed calculations and figures

are provided in Annex 5 and have been submitted to the DOE.

Scenario IRRProje ct [%]

Payback Period_{Projec t} [years]

Standard scenario (actual energy prices) 7.1 7.6

Increase of electricity prices by 10 % 9.5 6.6

Decrease of electricity prices by 10 % 4.6 8.9

The results clearly show that the return on investment for the project activity is not economically

attractive if no CERs can be generated and sold.

This situation changes when revenues from CER-sales are considered. Again, the project’s IRR has been

calculated for different scenarios. In the standard scenario, a constant CER-price of 15 US$/CER has

been assumed both for the period before 2012 and the period afterwards. This means an additional

income of 382,757 US$ per year (average of crediting period). As sensitivity analysis, a CER-price

increase and decrease of 20% has been assumed for all CERs generated after 2012 due to the current

price uncertainty. Results are summarised in the following table:

Scenario Name CER-Price IRRProje ct [%]

Payback Period_{Projec t} [years] Standard scenario -

Constant CER-prices post 2012 15 US$/CER 21.4 4

High price scenario -

Increase of CER-prices by 20% post 2012 22.4 4

Low price scenario -

Decrease of CER-prices by 20% post 2012 20.3 4.9

The results show that the CER-revenues make the project economically feasible.

5

(15)

1b) Financing of the installations:

Another challenge has been the financing of the installations via dept capital. Honduras’ currency, the

Lempira, bears a significant rate of devaluation against the USD: since the acquisition of Company's

Honduran subsidiary in 1989, the Lempira has continually devalued against the USD: from 2.0 Lempira

to the USD in 1989 to 13.03 Lempira to the USD at January 31, 1997

6

and to 18.9 by the end of 2006

7

.

Without CER-revenues, all income generated by the project will be in Lempira, while the installations

have to be paid in USD. Hence, the expected income in hard currency through CER-sales allows

Exportadora del Atlántico to hedge against the devaluation of the Lempira.

2) Barriers due to prevailing practice

Methane recovery

Methane recovery facilities are rarely found in Honduras. The predominant technology for wastewater

treatment is an open anaerobic lagoon system. Besides CDM revenues, there are almost no incentives for

companies to invest in a more expensive and complicated waste water treatment system with biogas

capture. There are three similar projects in Honduras, and all of them are also being developed as CDM

project activities:

EECOPALSA CDM – Project Number 492: biogas recovery and electricity generation from

Palm Oil Mill Effluent ponds. The technology provider for this CDM project activity is also

BIOTEC.

Cervecería Hondureña Methane Capture Project, located in San Pedro Sula – CDM Project

Number 896. A different technology (UASB tank digester) has been applied by the project.

Energeticos Jaremar – Biogas recovery from Palm Oil Mill Effluent (POME) ponds. The project

is currently in the validation phase; the global stakeholder consultation was conducted in summer

2007.

Renewable electricity generation from biogas

Honduras has undergone efforts to reduce its dependency on fossil fuels, which resulted in a number of

laws promoting the use of renewable through fiscal incentives

8

. However, the results of these initiatives

are very modest. The prevailing practice is electricity generation using fossil fuel. The use of fossil fuels

in Honduras even has increased in the past years, especially in energy generation sector, where fossil

fuels are responsible for over 61% of all electricity generation in the interconnected electricity grid

system. This trend is not expected to change as the expansion plans of the national electricity company

include investments in thermal generation capacity in the coming years.

Consequently and apart from the CDM initiatives mentioned above, there are no other digesters in

Honduras that recover biogas and take advantage of this, as part of any wastewater treatment system in

any other industrial context.

(16)

Conclusion of additionality assessment

The identified barriers clearly demonstrate that the project faces several barriers that prevent the

implementation of the project. Without the CDM-incentive, these barriers would lead to a continuation of

the existing system of open anaerobic lagoons. The expected revenues from CER-sales help to overcome

these barriers.

B.6.

Emission reductions:

B.6.1. Explanation of methodological choices:

1. Methane capture:

As mentioned above, the project activity falls under option

(iv) Introduction of methane recovery and combustion to an existing anaerobic wastewater treatment system such as anaerobic reactor, lagoon, septic tank or an on site industrial plant of AMS III.H.

Hence, emission reductions (ER) through

the avoidance of methane emissions from the existing waste

water treatment system are calculated as follows:

As no equipment will be transferred from another activity, and none of the existing equipment will be

transferred to another activity, leakage effects do not occur. Hence, Leakagey is set as zero.

Project activity emissions are calculated strictly in line with AMS III.H while considering the following items:

Emissions from dissolved methane in treated wastewater in year “y” are calculated as:

In doing so, the standard default values of AMS III.H are applied. As the depth of the existing lagoons is

more than 2 metres, a MCF of 1.0 is chosen in line with table

III.H.1. For CODy,ww,treated it is expected that

(17)

PE

y,s,final:

Emissions from anaerobic decay of the final sludge produced in the year “y” are neglected in

line with AMS III.H, because the final sludge is used for soil application (fertilizer).

Emissions from methane release in capture and flare systems are calculated as:

Where:

, and

Emissions from dissolved methane in treated wastewater are calculated as:

The baseline scenario is t

he existing anaerobic wastewater treatment system without methane recovery and combustion (option iv of AMS III.H), and hence baseline emissions are calculated as:

In line with AMS III.H,

baseline emissions are calculated as per the formulas provided for calculating the project emissions, with the exception that MCF lower values in Table III.H.1 are used.

2. Renewable electricity generation:

With regard to the generation of electricity from biogas, emission reductions are calculated applying the approved small scale CDM baseline methodology AMS I.D. “Grid connected renewable electricity generation”. Emission reductions are calculated from the expected amount of displaced grid electricity, multiplied with the calculated emissions factor of the grid.

The latter has been calculated as Simple OM (generation weighted average), following the procedures in AMS I.D and the „Tool to calculate the emission factor for an electricity system“, based on generation data of the years 2004, 2005 and 2006. Data has been obtained from the national Electricity Provider ENEE, considering total generation excluding low cost/must run, including approved CDM projects, and including electricity imports. Details of the calculation and its outcome can be found in Annex 3.

B.6.3 Ex-ante calculation of emission reductions:

Emission reductions are calculated as the difference between baseline emissions and project emissions

strictly in line with the provisions and formula as defined in AMS III.H, AMS I.D, the „Tool to calculate

the emission factor for an electricity system“ and as explained in section B.6.1 of this document.

Details of calculation and annual results over the crediting period can be found in Annex 3. The

following tables summarise project activity emissions, baseline emissions, leakage and estimated

emission reductions for the individual components of the proposed CDM project activity.

It may be noted that the decrease of project emissions and baseline emissions over time is due to

decreased production in the Palm Oil Plant (due to decreased harvest from palms according to the natural

growth cycle) and responding increase of wastewater volumes.

B.7.2 Description of the monitoring plan:

Emission reductions will be determined by quantifying the amount of methane destroyed and the amount of electricity generated:

1. Methane capture:

According to para 26 of AMS III.H – which is relevant for baseline option iv) – “

the calculation of

emission reductions shall be based on the amount of methane recovered and fuelled or flared, that is

monitored ex-post. Also for these cases, the project emissions and leakage will be deducted from the

emission reductions calculated from the methane recovered and combusted, except where it can be

demonstrated that the technology implemented does not increase the amount of methane produced per

unit of COD removed, compared with the technology used in the baseline.

”

In fact, the project activity will not increase the amount of COD removed, because it will simply capture

the methane that is released from the wastewater, but it will not enforce the anaerobic processes (as for

example in a closed digester). Hence, project emissions regarding methane emissions from wastewater

and leakage do not have to be deducted from captured and fuelled/flared methane.

(26)

In summary, emission reductions are calculated as:

ERww,y = wCH4,y * BG_GENy + wCH4,y *

η

Flare * BG_Fl,y – EC_BGSy * CEF

All parameters are defined in section B.7.1.

2. Renewable electricity generation:

Emission reductions due to the replacement of grid supplied electricity will be determined by multiplying the net electricity generation of the biogas system with the grid emissions factor:

ERBG,y = EGy * CEF

All parameters are defined in sections B.7.1 and B.6.2. of this document.

Total emission reductions of the project activity will be determined ex-post by summing up emission

reductions from the two components:

ERProject, y = ERww, y + ERBG, y

A summary of measurement points of the monitoring plan is given in Figure 3.

Exportadora del Atlantico, the project owner, hired Biotec to operate the biogas plant. Biotech has got

the monitoring responsibilities for three years. During this period all data of process will be recorded by

a Scada system and stored on a hard disk with a redundant copy on a global database located in the main

office (Cali, Colombia). Biotec has developed a training school to provide training to its personnel.

Operators has been receiving training in biogas and generating system operation. Also, training in

instrumentation and monitoring system has been provided through Biotec experienced engineers.

The plant chief performs daily monitoring and control of operating procedures, data collection and daily

reports. In addition, the monitoring system can be displayed by Biotec experts anywhere (remote

supervision). Biotec performs internal audits each three months through experienced engineers coming

regularly from the main engineering office.

All data gathered and a description of measures that constitute the monitoring plan will be kept by the management for at least two years after the crediting period, permitting any future auditing of the values.

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 in section A.2 of this document, the operation of the new wastewater treatment system will

not impact the environment negatively, but will improve the quality of discharged water (COD-load and

other parameters, see section A.2).
