Computes are disposable… 3-5 year service life Computers are disposed of because a) have become outdated b) failure of internal electronic component
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 break a computer down to its basic elements ?
Plastic components Takes little to no wear Recyclable Polystyrene What designers are designing
Metal components Little to no wear Majority of computer body Recyclable steel
Electronics Limiting lifespan factor “out dated” Toxic components MUST be disposed of properly
Breakdown Everything else Case: 150+ parts 300+ manufacturing operations Internalized electronics:DVD R/RW drives wireless adaptors card readers additional storage Misc: Cables, connectors, labels, hardware 3 main components Desktop Computer Motherboard w/processor & memory Excess Hard drive Power supply
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?
Case Electronics Minimize Minimize Externalize Choose Choose Front end Number of case parts Number of Manufacturing operations Number of electronic parts Efficient engineered “off the shelf” components (integrated parts, laptop hard drive, USB/SATA connections) Single renewable & recyclable material Manufacturing operations w/low impact “Optional” components (added as needed: DVD R/RW, wireless)
Externalize optional components Middle Flexibility in usage Plug and play/easy to swap components User customization Components are not “mentally tied” to a particular computer and are separate, thus can be used on other machines Maximize component & computer life separately
Case Electronics Dismantle Minimize Minimize Recycle Recycle Externalize Back end Number of electronic parts discarded at a time 100% Opportunity to easily recycle components Simple Physical quantity of parts discarded reuse external components
