Questions

4. Introduction Plastic Film Consumption is Increasing
Plastic Material is Sustainable in Flexible Packaging
Plastic Film Consumption is Increasing
Plastic Film Waste is also Increasing
Plastic Film Waste is Concern for Environmental
- Thinness
- Life of plastic film
- Non-biodegradability : Longevity in environment
Plastic Film Waste Issues
Plastic Film Waste Sources

5. Need of the Work
76% of plastic film waste is unutilized and goes as resource waste
MSW and litter as major source of plastic film waste
Mixing of Thin Plastic and other content of MSW- Behavioral problem
Impaired Reverse Logistics : Issue of Segregating Mixed plastic film waste

6. Literature review Segregation of plastic film waste after collecting
The waste of Energy and time
Large volume is uncollected
Two-bin system: 2 bins, Cost, no provision to segregate at mind
Green supply chain efforts : Not truly integrated

7. Design of Instrument Design Considerations
Provision to segregate at source
Multiple Compartments
Mass / weight of bin
Material requirement and cost
Loading and unloading of waste
Labeling, safety, ETC.

12. Data Analysis and Results
Waste composition is matching with other studies except dust
Waste generation is less i.e. ranging from 140 gms to 420 gms
Instrument segregated household waste for 80 % attempts

13. Conclusion
Designed Instrument is capable of segregating household waste at source.
The methodology i.e. design for instrument is workable and leads to 80 % success rate.
Mixing of household waste into each other is avoided at source.
Segregated waste shall flow through reverse logistic streams and ultimately reach at recycling.
Littering will reduce.
