2
Table Of Contents Objectives Disassembly How it operates Solutions
Marketing Matrices
3
Objectives Shift focus from “disposable” to “reusable”
Create a more marketable product. Definition and need
4
Disassembly Stickers and film were easily removed
Camera is made mostly of plastic Two metal springs and circuit board are only pieces not made of plastic Plastic parts Non-plastic parts
5
How It Works Battery charges flash
Film is wound and spring loaded by manual winding Shutter button releases spring and shutter, also charge is released in a flash
6
Solution #1 Cameras will be collected Plastic is easily recycled
Melt used cases Reform into new cases Reduction in wasted plastic
7
Solution #2 Current Batteries contain more energy than necessary
AA Batteries contain 140 mAh Camera only requires a battery with 48.6 mAh Silver-Oxide batteries are smaller and more sustainable Silver Oxide Alkaline (New School) (Old School)
8
Circuit board on camera (above) and detached from camera (below)
Solution #3 Reuse circuitry Quality Control Test life of circuit board Requires most manual labor Most dramatic impact on e-waste Circuit board on camera (above) and detached from camera (below)
9
Marketing Smaller battery will allow case size to be reduced
Green sticker to represent new e-waste reduction methods Link to website for people to learn what is changed
10
Decision Matrix Recycle Plastic Smaller Battery Reuse Electronics Cost
Saves plastic costs, plastic is melted to mold anyway. + Same price (perhaps slightly more expensive). Net reduction in costs, make fewer boards. Sustainability Less plastic in landfills. Less volume, different material. Drastic reduction in circuit board waste. ++ Totals 2 3
11
Decision Matrix Weights Recycle Plastic Smaller Batteries
Reuse Electronics Cost 50% 7 5 Labor 10% 6 2 Sustainability 30% 8 9 Difficulty of Implementation Totals 100% 7.1 2.9 5.9
12
Conclusion Disposable cameras are unsustainable
Changes could save money and create less e-waste
