Review of Second Working Group

Issues regarding solid waste management has

been identified

Technical options has been considered.

Preliminary future amount of solid waste has beenprojected.

• How to incorporate the solid waste management facilities in

the future land use plan• Necessary of technical options except final disposal

After Improvement

- Reduction of odor

- Reduction of rodents and birds

- Prevent the leachate leakage

- Improvement of unloading andwaste spreading activities

- Improvement of waste picking

activities

Open dump site (e.g.

Dandora dump site)

Image of Sanitary Landfill

Site

Current issues

- Odor problem

- Rodents and birds

- Leakage of leachate to water

course- Bad condition of inner and

access roads

- Bad condition of unloading

place

Improvement

- Cover soil

- Liner system

and leachate

treatment facility-Improvement of

access and

inner roads

-Monitoring by

waste pickers

and landfillofficers

Improvement of Treatment and Disposal System
