Consideration of Technical Options
(Treatment and Disposal)
Options Merit Demerit
Landfill -Comparatively cheaperoption-Technically feasible
-No waste reduction
3R+Landfill -Comparatively cheaperoption-Technically feasible
-If no cooperation with wastegenerator, not enough wastereduction
3R+Incineration+Landfill
-Effective volume reductionof waste
-Expensive for initial cost andO&M cost
3R+Composting+Landfill
-Effective volume reductionof organic waste-Not expensive option
-Waste separation isnecessary and necessity ofmarket of compost

After Improvement- Reduction of odor- Reduction of rodents and birds- Prevent the leachate leakage
- Improvement of unloading andwaste spreading activities- Improvement of waste pickingactivities
Open dump site (e.g.Dandora dump site)
Image of Sanitary LandfillSite
Current issues- Odor problem- Rodents and birds- Leakage of leachate to water
course- Bad condition of inner andaccess roads- Bad condition of unloadingplace
Improvement- Cover soil- Liner systemand leachate
treatment facility-Improvement ofaccess andinner roads-Monitoring bywaste pickers
and landfillofficers
Improvement of Treatment and Disposal System
(Difference between dump site and sanitary landfil l site)
