All landfills need to be degassed. Al Qusais landfill has developed from a dump site to a well managed landfill that is being becoming a source of pride rather than worry for Dubai and a showcase for the region. Working together towards a cleaner future. It is our responsibility to leave the Earth a better place for our children.

1. The Al Qusais Landfill
Harnessing Waste
Energy

2. Landfill Gas Projects – The Mission
Mission of GESS with the implementation of LFG projects in the region
 Supporting the Dubai integrated energy strategy of 2030 set out by the Supreme Council
of Energy and His Highness Sheikh Mohammed bin Rashid Al Maktoum which aims to
diversify energy sources and to preserve the environment.
 Al Qusais Project – Dubai UAE large scale registered CDM Generating Power
 Diversified is fuel mix
 Added a new energy source
 Reduced the need and use of diesel for daily operations
 Reduction of Green House gases of Over 400,000 tons of CO2 equivalent per year.
The Al Qusais CDM project alone is equivalent
to reducing the environmental impact of taking
over 80,000 cars off the roads.

3. What is a TYPICAL LANDFILL - Al Qusais
Landfills are living organisms. It
is the decomposition of the
organic portion of the waste
that produces landfill gas.

An untreated landfill has an adverse impact on the
environment, it is a hazard that is a primary cause of CH4
emissions globally and is a contributor to Global Warming.

4. MSW 35% Organic- Waste Generates LFG
Hotel and restaurant
waste, great gas
production
Household waste in plastic bags, usually
wet
Garden and park
waste,
decomposable
All of these waste streams have great gas
production potential
Industrial waste;
 Plastics
 Wood
 Metals
 Glass
 Building rubble
 Concrete blocks
No gas production
Landfill Gas (LFG) is typically composed of;
 Methane CH4 50 – 60 % vol.
 Carbon Dioxide CO2 35 – 45 % vol.
 Nitrogen N2 0 – 20 % vol.
 Oxygen O2 0 – 5% vol.
The 4 phases of LFG – Phase IV Methane production

5. Gas Collection Design and Engineering
 The Detailed engineering and the design of the gas collection
network that has over 25 km of pipes underground have
enabled us to optimize the potential.
 Al Qusais is an award winning site that has surpassed all
expectations.
 Phase 2 will be to extend the gas network and the
development of 20 Mw power from landfill gas and the
fulfillment of many years of hard work.

6. Dubai Municipality marks ‘green’ milestone with Al
Qusais Landfill now fully powered using landfill gas
• First time that landfill gas is converted to generate 1MW electricity in
the region; in line with Dubai Municipality’s vision to generate 20 MW of
power from landfill gas by 2020
• Fully registered with UN, the large-scale CDM project underlines Dubai’s
focus on sustainable development
• Initiative will reduce greenhouse gas (GHG) emissions equivalent to over
400,000 tons of carbon dioxide into the atmosphere
• Project development, design and construction by Green Energy Solutions
& Sustainability LLC with GE’s Jenbacher gas engine deployed on site to
generate power
What was a dump site, is now a well managed
environmental landfill that is a source of power and
pride.

7. Current Situation in the Region and why
we should do something!!
Landfilling is still an option here – Al Qusais receives over 6000 tons of waste per day.
In Europe and North America the existing landfills are a source of power as it should
be here as well. The European trends are moving away from landfilling.
The top methane sources are the decomposition of wastes in landfills. A new
emphasis on methane would require us to get smarter about capturing methane at
landfills, www.earthisland.org Earth Island Journal
 Statistics show that Methane from landfills is harmful (IPCC – intergovernmental panel on climate change)
 CDM and Kyoto Protocol fix the GWP – Global Warming Potential of Green House Gases
– CH4 Methane (landfill gas) has a GWP of 25
 We are able to reduce the impact that landfill gas has on the environment and generate
power, there are no excuses left.

8. Climate Change – The commitment from
the UAE
Climate Change – This phrase has been in the news on a daily basis. It is a doomsday message
that is being relayed by everyone from Political leaders to Religious Leaders.
During the last Conference of Parties (COP) 19 meeting on climate change, the UAE committed to
addressing climate change from an economic, social and environmental point of view
 Includes implementing commercial clean energy projects,
 making investments into clean technologies
 expanding development assistance my making clean energy accessible to all.
The UAE is meeting that challenge and the Al Qusais landfill gas to power project is a key
milestone as well as Solar Parks, Smart Cities applications and recycling initiatives from the
Dubai Municipality Waste Department.

9. Power Generation Potential: Landfill Gas
 As per the Technical specification of GE Jenbacher:
• 1 MW supply running at Al Qusais Site,
• Equipment code JGC 320 GS-B.L ,
• specific gas consumption is 590 Nm3 per 1058 KW generation.
• = 551.4 Nm3/MW of power generation.*
*This is how much gas you will need to produce 1 Mw of power (electricity)
Al Qusais is currently flaring 5,800 Nm3 per hour of Landfill gas. With this amount of
gas the power potential is 10 – 12 Mwh with the current gas collection system.

10. Economics: Landfill Gas Power Generation
• Power generation ( Installed capacity ) = 12 MW
• Annual operating hours @ 330 days = 7920 ~ 8000 hrs
• PLF (Plant Load Factor) = 90%
• Auxiliary consumption : 5%
• Net generation : 12*8000*90%*(100-5)%
82080 Mwh
This is equivalent to setting up a 60 MW solar power project at a fraction of the cost
The lowest hanging fruit on the renewable markets
Landfill gas is a power source that can provide sustainable renewable energy. It
is an important renewable energy source.

11. Comparison of Solar Power to Landfill
Power Generation
Solar Power LFG (Landfill Gas Power)
20Mw equivalent 28,000 Mwh 20Mw equivalent 142,560 Mwh
CO2 reduction 46,000 tons/yr CO2 reduction 835,000 tons/yr* including
CH4 destruction from flaring project
Investment 100,650,000 AED Investment 70,000,000 AED
Cost of Power = AED 3,594/Mwh 3.59
Kw
Cost of Power = AED 491/Mwh

Maintenance is lower Maintenance is higher
Year by year degradation is higher Year by year degradation is lower
Success rate is good Success rate is excellent
Renewable energy source Renewable energy source

12. So then why are there not any other
Landfill Gas Projects in this region??
Main reasons:
 Legislation
 No feed in tariff
 Waste management strategies
All of this has changed over the past two years and the time has come to recognize that
renewable energy and alternatives to fossil fuels is necessary and a global
responsibility.

13. Zero Wastefulness – Recycling Initiatives and Waste
management strategies to support sustainable
growth.
 Regionally there are initiatives to recycle, but recycling is in the early stages of
development, which means that there is an opportunity to maximize the existing
landfills and capture the energy that is stored in the high organic waste stream that
is harming our environment.
