Flow of presentation Introduction – 2 Min. Need of the work - 1 Min. Literature review - 2 Min. Design of Instrument - 3 Min. Design of experiment – 2 Min. Data collected and analysis- 2 Min. Results – 1 Min. Conclusion – 1 Min. Summary- 1 Min. Questions
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
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
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
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.
Table01. Composition of Household Waste Household Waste Composition Table01. Composition of Household Waste Sr. No. Type of waste Composition % Composition % 01 Vegetable/food waste 30 07 Metals, 3 02 Dust, 29 08 Wood, 03 Paper 15 09 Coal 2 04 Plastic 10 Ash 1 05 Glass 11 Brick/pottery 06 Clothe Design Requirement: Per Capita Waste Generation = 0.5 Kg / day Average Family Size = 06 persons Fluctuation = 1 Kg No. of Compartments = 11 reduced to 05 + 03 Individual waste volume
Designed Instrument
Validation of Instrument Design of Experiment # Selection of user = based on willingness # Sample Size = 01 # No of Samples = 25 # Uncertainty in measurement = 10 gms # Frequency of Data collection = Morning daily 2. Constraints # Cost of project # Willingness of user
Data Collected Table02. Collected Data Day Waste Composition in grams Total Remarks Food Paper Plastic Dust Others Textile Glass Scrap 1 250 100 20 10 370 Segregated 2 200 60 280 3 50 290 4 220 260 5 300 400 6 140 7 150 190 8 - 30 Not-segregated 9 240 40 360 340 11 230 12 350 13 160 14 15 16 420 17 18 170 90 19 180 270 21 210 80 320 22 23 24 25
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
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.
