Technology makes our lives better, but…

we have a bit of a problem
![Page 4: Final Thesis Presentation For Dell](https://reader038.fdocuments.net/reader038/viewer/2022103017/55648814d8b42a361d8b5045/html5/thumbnails/4.jpg)
Computers are disposed of becausea) have become outdatedb) failure of internal electronic component
Computes are disposable…3-5 year service life
![Page 5: Final Thesis Presentation For Dell](https://reader038.fdocuments.net/reader038/viewer/2022103017/55648814d8b42a361d8b5045/html5/thumbnails/5.jpg)
Approx. 500 million waste computers in the U.S
Internal components contain toxic heavy metals, such as mercury, cadmium, and lead.
Computer cases are majority of physical waste
Current casing makes dismantling for recycling difficult

How do we make a more sustainable solution ?

How do we break a computer down
to its basic elements ?

Plastic components1. Takes little to no wear
2. Recyclable Polystyrene
3. What designers are designing

Metal components1. Little to no wear
2. Majority of computer body
3. Recyclable steel

Electronics1. Limiting lifespan factor “out
dated”
2. Toxic components
3. MUST be disposed of properly

Design Statement
Make a sustainable computer that:
Reduces total number of materials, parts & manufacturing operations
Uses easily renewable materials & low impact manufacturing processes
Easily dismantled, recycled & allows for reuse of parts
How are we going to do it?

Components are not “mentally tied” to a particular computer and are separate, thus can be used on other machines
Maximize component & computer life separately
