Poor waste management !
• Large increase in population & Economical development
Background : Solid waste Situation
• Limited financial resources
• Limited trained people & shortage of equipment

Objectives
7
• Monitor the emission potential from
municipal solid waste landfilled in Jordan .
• Simulate the influence of climate on the
emission potential of landfills located in
semi-arid areas.
• Recommend new design parameters and
operation mods for landfill in semi-arid
areas.

• Source separation is not easy to start nowadays in Jordan
• The current regulation stand against developing SWM
• Anaerobic digestion is a very efficient waste treament process
• It produces bioenergy (heat, electricity, fuel, gas)
• A great environmental biorefinery !
Conclusion:
