<strong>Socio</strong>-<strong>economic</strong> <strong>assessment</strong> <strong>and</strong> <strong>feasibility</strong> <strong>study</strong>
on sustainable e-waste management in Ghana
August 2010
Business outputs
Try to quantify the enterprises’ monthly / annual production in absolute <strong>and</strong> monetary terms.
Example: The enterprise repairs approximately 800 mobile phones per month. They are sold to the
street vendors for $ 5–10 per piece, depending on the quality. The revenues from scrap mobile
phones are negligible <strong>and</strong> may sum up to $ 50 per month. On average 1000 waste mobile phones
are sold to scrap dealers per month.
Business inputs
Try to quantify the enterprises’ monthly / annual business inputs needed to generate the
described outputs. Focus on materials <strong>and</strong> running costs (no investments into machinery or
others)
Example: The enterprise purchases between 1500–2500 used <strong>and</strong> obsolete mobile phones per
month, which cost between $ 0.50 <strong>and</strong> 1.00 per piece, depending on the quality <strong>and</strong> condition.
Amongst these mobile phones are also many unrepairable devices, which are important sources of
spare parts. The enterprise uses approximately 2–3 mobile phones to produce a functioning one.
Besides mobile phones, there are little further materials needed: Solder, cleaning liquid, glue <strong>and</strong>
batteries, which are purchased on the local market. These additional costs sum up to less than 50$
per month.
