Onyx Gas Capture and Flaring Project
BackgroundBackground
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

Onyx Gas Capture and Flaring Project
Project DescriptionProject 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

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)

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

AdditionalityAdditionality
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

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
