2. Different methods of MSW management
• Composting…..
Indore method (aerobic),
Banglore method (anaerobic),
Vermi composting.
• Incineration,
• Pyrolysis (burning at oxygen free atmosphere),
• Sanitary landfill.
• Shredding and pulverization.
• Barging it into the sea.

3. Pyrolysis-
• Burning at oxygen free atmosphere
• Destructive distillation
• By-products-
1. A gas streams-hydrogen, methane, CO,CO2 etc.
2. A liquid fraction-tar/oil stream- acid, acetone
and methane.
3. A solid fraction-charcoal and other inert
materials.

4. Sanitary land filling
