Onyx Gas Capture and Flaring Project Alexandria, Egypt

Onyx Gas Capture and Flaring ProjectAlexandria, Egypt Amr Abdel-Aziz, Ph.D. Integral Consult, Egypt

Background Onyx Alexandria • Onyx Alexandria is owned by Veolia Environment • Veolia is Ranked 1st in Europe and 2nd worldwide in the field of solid waste collection and disposal • Operates in 33 countries with 68,000 employees

Background Contract • 18 district served with a total area of 7,200 km2 • 2,700 t/d to be collected, part composted and the remaining is landfilled • Biogas collection and leachate treatment systems should be installed • No biogas capture rate specified in the contract

Location of Landfills • Borg El Arab (All seasons except summer) • El Hammam (Summer season)

Project Description • A biogas collection system is installed • Collected biogas is utilized for leachate treatment • Onyx is not obliged to collect excess methane not needed for leachate treatment • Will install additional 3 flaring units of capacity 1,500 m3/h each to flare excess methane

Project Description Biogas Collection Leachate Collection Leachate Treatment

Baseline – AM0002 Applicability • Onyx is responsible for all aspects of the landfill • Contract awarded through a competitive bid • Onyx should collect the biogas (no specific quantity)  quantity used for leachate treatment is the baseline • No other landfill in Egypt collects and flares biogas • No generation of electricity using the captured landfill gas occurs (may be considered in the future)

CH4projected,y:Methane projected to be generated during a given year K: Decay rate Lo: m3 CH4 / t MSW Wastecontract,t:Waste projected to be lanfilled at year t Baseline - Application • First order decay model – IPCC guidelines

Baseline - Application Assumption of k • K depends on local conditions e.g. temp., moisture content of MSW, pH, and nutrients • IPCC guidelines  ranges from 0.005 to 0.4 per year • US EPA  0.1 for wet conditions • Moisture content in Alexandria waste is 60% • K assumed 0.05 for conservativeness

Baseline - Application Estimation of Lo MCF Methane correction factor assumed 1 DOC Degradable organic carbon assumed 0.19 (IPCC recommends 0.21 for Egypt) DOCf Fraction of organic carbon converted to landfill gas (assumed 0.77) F Fraction of CH4 in landfill gas (assumed 0.5)

Baseline - Application W06 W04 W03 W05

Baseline - Application Projected Methane Generated - BA

Baseline - Application Projected Methane Generated - HA

Baseline - Application Methane Needed for Leachate and 20% of Generated Methane - BA

Baseline - Application Methane Needed for Leachate and 20% of Generated Methane - HA

Baseline - Application Baseline Methane Emissions (m3)

Baseline - Application Baseline Methane Emissions (t CO2e)

Baseline - Adjustment Correct  CH4contract,y:Methane required to be flared each year as per contract FD: Fraction of methane collected in baseline CH4baselinr,y:Methane specified in contract adjusted by actual waste and actual % CH4 in LFG R: Fraction of CH4 in LFG Project Correct  FP: Fraction of methane collected in project CH4flared,y Actual methane flared during year y

Additionality Economic • The baseline emissions are based on the approval of the leachate treatment system • For other landfills, systems approved by the government are passive collection system (max. efficiency 20%) • No regulations for biogas collection -- only guidelines which does not mandate the use of specific technology • Additional flaring equipment  additional costs  No expected additional revenues  continue business as usual is most attractive course of action

Monitoring Methodology • Applicability • Project activities that reduce green house emissions through landfill gas capture and flaring • Baseline established by a public concession contract

Monitoring Methodology • Monitoring emissions from project activity • Measured • LFG (c) • % CH4 in LFG (c) • Temp. (c) • Pressure (c) • SW disposed (d) • Calculated • Amount of methane flaring for baseline (a) • Amount of methane collected in addition to baseline (a) • CO2e reduced (a) a annual, d daily, c continuous

Monitoring Methodology • Quality Control / Quality Assurance Procedures • Procedure for equipment calibration • Will be included in ISO 9000/14000 certification process

Crediting Period • Contract duration is 15 years • Started in October 2001 and ends in October 2016 • Project expected to start in June 2005 • 11 y 4 m will remain in contract duration • First crediting period is 7 years

Environmental Impacts • Flaring will also destroy compounds in the biogas such as VOCs • Negative impacts of methane: • Odour • Risk of explosion • Negative impacts of VOCs • Odour • Toxicity • Carcinogenic • Photochemical reactivity  O3 health effects and damage to crops and plants

Project Status • PDD: Final Draft • Financing Situation: Self Financed • DNA Approval: Preliminary approval • Project Implementation: Not yet

Bioreactor Landfills at Greater Cairo PIN

Project Description • Waste is actively degraded rather than decomposed slowly • Leachate will be recirculated and monitored • Gas generated will be collected and flared • A pilot project has been implemented at Waffa and Amal Landfill in Cairo and is currently under evaluation

Expected CERs • Crediting Period: 14 years. • Project Start Date: 2006 • Annual CERs Expected: 430,000 (average) • Total expected CERs: 6.5 M
