3 Introduction In 2013 world population was about 7.2 billion and is projected to increase by 1 billion by the year Population growth and associated with increase in standard of living and urbanization levels will come with an ever-increase in Municipal Solid Waste (MSW) generation and energy demand. Current global MSW generation level is 1.3 billion tons/year, and is forecasted to reach about 2.2 billion tons/year in 2025.

4 Global Perspectives of Waste-to-Energy Waste to Energy (WTE), are being utilized globally as environmental protection measures and energy renewable source. WTE is a proven and efficient option to handle the MSW disposal challenges WTE also can contribute to global energy demand.

5 Global Perspectives of Waste-to-Energy. Global Current and Forecasted Value of WTE Market

6 Municipal Solid Waste Management in Saudi Arabia KSA population has increased from 7 million in 1975 to about 27 million in 2010 with an annual rate of 3.4%.

7 Municipalities are governing MSW management in Saudi Arabia. The current MSW practices in Saudi Arabia is to collect t and dump in landfills or dump sites. A few initiatives for MSW recycling are in place in the Eastern Province of Saudi Arabia. These initiatives are in small scale and their contributions are not well documented. KSA MSW wastes consists of 37% organic materials, 28.5% paper, 5.2% plastics, 8.3% mineral, 4.6% glass, 8% wood, 6.4% textile, and 2% others. Municipal Solid Waste Management in Saudi Arabia

8 In July 2013, the Saudi Cabinet approved new MSW management regulations. The new regulations aims to ensure the implementation of an integrated framework for MSW management in the country. In 2010, the government initiated the King Abdullah City of Atomic and Renewable Energy (KACARE). KACARE is proposing an impressive plan for renewable energy utilization that includes WTE facilities. The two decade plan includes production of up to 54 GW from nuclear and renewable energy sources. Municipal Solid Waste Management in Saudi Arabia

9 To assess the potential of WTE in KSA two scenarios were developed: – Mass Burn with Recycling. – Mass Burn. The Mass Burn scenario implies full utilization of MSW for WTE production. Mass Burn with Recycling assumes removal of all potentially recycled materials from the waste stream and utilizing the remaining MSW for WTE production. The potential electricity generation of the two scenarios were calculated based on: -MSW generation forecast up to the year MSW Compositions -Caloric values of each materials Potential of WTE in Saudi Arabia.

10 Mass Burn with Recycling Potential of WTE in Saudi Arabia

11 Mass Burn Potential Contribution of Waste-to- Energy in Saudi Arabia.

12 The Mass Burn with Recycling scenario result shows a potential to produce about 166 (MW) of electricity by the year This value forms about 0.14% of the 120 GW peak electricity demand in The figure shows the potential to produce about 2073 Megawatt (MW) of electricity from MSW by the year This value forms about 1.73% of the 120 GW peak electricity demand for that terminal year. The Mass Burn scenario can produce 12 times WTE electricity more than the Mass Burn with Recycling scenario. Potential Contribution of Waste-to- Energy in Saudi Arabia.

13 Environmental Values of WTE in Saudi Arabia The Environmental value of the two Scenarios were estimated based on EPA USA approach. Three Environmental criteria were considered -Energy saving -Net greenhouse gas emission reduction -Landfills area reductions The Environmental value for KSA and per city for the major six cities up to year 2032 will be forecasted.

15 Energy Reduction Forecast based on Mass Burn Scenario Environmental Values of WTE in Saudi Arabia

16 Materials Waste Composition % Mass Burn with Recycling (MTCE/ton of MSW) Mass Burn (MTCE/ton of MSW) Paper Plastic Glass Wood Textiles Organic Others Total (MTCE/ton) Net greenhouse gas reduction in MTCE per ton of material for the two scenarios Environmental Values of Waste-to- Energy Facilities in Saudi Arabia

17 Landfill Area Forecast Based on complete landfilling Environmental Values of WTE in Saudi Arabia

18 Landfill Area Saving Forecast Based on Mass Burn With Recycling Scenario Environmental Values of WTE in Saudi Arabia

19 Landfill Area Saving Forecast Based on Mass Burn Scenario Environmental Values of WTE in Saudi Arabia

20 Conclusion The results show WTE has great potential in the Kingdom. WTE can be a good contributor to electricity supply in the Kingdom. The Environmental Values are tremendous.
