Selected Waste Management References in ME

• Al-Hasa Environmental Study, Kingdom of Saudi Arabia (2010-2011)As one project component, COWI established baseline information about the current waste management system in Al-Hasa Municipality. COWI carried out a waste characterization survey and provided recommendations on how to upgrade the existing system , identified appropriate waste handling technologies and equipment etc.

• HSE Plan & Hazards Risk Assessment for Medical Waste Collection and Transportation, UAE (2010)For the Lebanese waste operator Averda, COWI carried out an Health, Safety and Environmental Plan covering medical waste collection and transportation. To identify health hazards, an risk assessment matrix and action plan on mitigation measures was developed.

• Electronic Waste Survey, UAE (2009)On behalf of a confidential electronics producer, COWI carried out an e-waste survey to map legislative waste treatment requirements, key stakeholders in the e-waste sector etc.

• Solid Waste Landfill - Environmental Impacts Assessment, Qatar (2008-ongoing) COWI is preparing an EIA for Mesaieed Industrial City's solid waste landfill is to handle 15,5003/month of industrial non-hazardous waste and 3,400 m3/month of domestic waste.

• Assessment of Landfill in Riyadh, Kingdom (2006)On behalf of Riyadh Municipality, COWI completed a landfill assessment with particular focus on landfill gas risks and potential utilisation of the gas.

• Strategic Framework for Private Sector Participation in Municipal Solid Waste Management, Jordan (2004-2005)COWI analysed and evaluated the existing situation of the private-sector participation in municipal solid waste services and identified weaknesses and gaps. In addition, COWI developed a detailed action plan for implementation of effective private-sector participation and organised training.

Treatment of waste – overview of options available

212010 An Introduction to Services & References

• Materials Recovery Facility (MRF)

• Biological Treatment (Composting/Anaerobic digestion)

• Mechanical Biological Treatment (MBT)

• Advanced Treatment (e.g. enzymatic degradation)

• Thermal Treatment

• Landfill


Thermal treatment– an overview


• Proven technologies

• Mass burning in grate boiler

• Circulating Fluidized Bed boiler

• Alternative methods

• Gasification

• Pyrolysis

• Co-combustion

• Coal fired power plants

• Cement Kilns

• Multifuel facilities


What does a modern WtE plant look like?



Energy balance for a WtE plant


(1) Gross electricity production 30 MW less in-house consumption 4 MW.

LHV 11 MJ/kg

Gross EL eff. 28%

Total eff. 88%


The use of energy recovered from thermal treatment – options available


• Electricity to the grid

• Absorption cooling

• Industrial process heat/steam

• Desalination of sea water

• Drying of sewage sludge or other substances

• Other purposes?


Why Waste-to-Energy as an integrated part of a sustainable waste management system?

An Introduction to Services & References

Materials recycling of all waste materials is not realistic (and physical possible)

Contribute to minimizing the CO2 production from the waste sector

Financial viable

Maximize diversion from landfilling – minimise landfill volume

Save fossil fuels (which are limited)

Enable synergies in between different treatment technologies


How much energy can be obtained from municipal waste?

• Average heat value of waste is app. 10.5 MJ/kg

• On average waste consists of app. 45% household waste and app. 55% industrial waste

• Thermal efficiency of new facilities app. 90%

• 1 ton of waste produces app. 0,7 MWh of electricity (~25%) and app. 2,0 MWh of district heating (~75%)

27


Energy from Waste in DenmarkSome highlights

• Plants owned by municipalities, inter-municipal companies or district heating/energy companies

• Extensive authority regulation of waste management and energy production

• Denmark the first European country to ban landfill of waste suitable for incineration

• App. 25% of the generated waste is incinerated, the rest recycled or landfilled(app. 7%) - Countries with much application of WtE are the most successful recyclers

• Lowest gate fee in European, due to efficient plants and high revenue stream from sale of heat and power

28


Energy from Waste in DenmarkSome highlights

• More than 100 years of experience with waste incineration in Denmark. First WtEplant 1904 at Frederiksberg, producing heat for the nearby hospital

• 30 MSW plants and 2 hazardous waste plants, treating some 3.5 mio. Tonnes per year

• Practically fully optimised energy efficiency
