There is a growing demand for solid waste materials
Municipal corporations are responsible for collection and disposal of solid waste in cities
They do very little
Waste pickers collect all kinds of solid waste and help environment

15. Waste Recycling SC Different types of waste pickers Economically poor
Living conditions are poor
Most unhygienic conditions
Sometimes organized under some entrepreneurs
Do all segregation and sorting manually

16. Junk Dealers Buys materials from waste pickers Sells to wholesalers
Roadside shops
No taxes and registration
Extra cost in terms of Money to corrupted officials

17. Wholesalers Specialized in one or two category of materials
Sell to recyclers and manufacturers
Have associations
More organised

18. Recyclers Some are in formal sectors Many in unorganized sectors
Not all are eco-friend
Supply materials to organized sector manufacturers

19. How to make it more formal
Govt. role
Companies role
NGOs role
