MSW Technology for Energy Recovery
1) Mechanical and Biological Treatment (MBT) - Production of Refuse Derived Fuel (RDF) and Solid Recovered Fuel (SRF) - Anaerobic Digestion - Incineration - Gasification and Pyrolysis - Plasma arc gasification
2) Landfill - Landfill Gas Recovery

Mechanical Biological Treatment (MBT)
The average waste produced per population in Thailand is around 0.7-1.2 Kg/day and the average is around 0.8 Kg/day and will be increased as the per capital income growth in the future.
Segregation of MSW for Energy Recovery
The Solid (MSW) will be processed by mechanical equipment and manual to separate recycle materials such as plastics, papers, metals, non combustible and combustible materials and organic materials.
-Plastics, papers and metal will be recycled
-Non combustible materials will be land-filled
-Combustible materials will be used as energy sources
-Organic materials can be fermented by anaerobic digestion to produce biogas or aerobic digestion to produce fertilizer
The combustible materials can be processed to make RDF or SRF for selling as fuel to other industry such as cement plant, steel industrial plant or power plant or use in thermal treatment to produce power.
The heating values of RDF or SRF are ranging from 18 to 25 MJ/Kg
Comparison of Energy Production from MSW by Various Technologies
The pyrolysis and gasification for MSW technologies are proven and many plants recently have been installed more than the Incineration technology due to less complication to clean the flue gas, cheaper investment, higher efficiency in generating heat and power. The Plasma arc gasification technology still under pilot scale testing and not commercially proven.
