Care for future Careful future
• No place for deposit of waste in the cities
• Use own yourself principle
• Segregation at source of having multi bin system
• Develop pits at in-situ place and help Decompose
• Develop habit of reducing waste ,
![Page 15: Recovery and Reuse of Landfill Waste Plastics](https://reader030.vdocument.in/reader030/viewer/2022012507/61837955b1c6503bb7298330/html5/thumbnails/15.jpg)

Dumping in Future
• Step 1: Primary segregation
• Step 2: Secondary dumping
Houses:
Pit inside the house to collect and help
decomposition
Community hall:
Provision for disposal at there own place
(PIT)
Multi story building :
Centre place to collect waste’
Municipal corporation :
• Collected and help reuse
• No dumping in any space
( Space Not available )

Waste Prevention
1. Reduce weight, toxicity & use of energy
2. Produce durable materials
Green Design
Better management :
• Remanufacturing
• Recyclable
• Reusing
• Compounding
• Scientific Disposal
Reduce, Reuse, Recycle
