Mobiltelefon utformad med EcoDesign
Sammanfattning
The environmental demands are increasing when it comes to product development. EcoDesign is
about minimizing the environmental impact of a product, considering the entire life cycle of it,
without compromising other qualities like function or cost. In this master of science thesis a
mobile phone has been analysed with Ten Golden Rules in EcoDesign regarding production, use
and End of Life. Also a functional and an environmental profile were made. The goal was to
make a new concept phone, based on the previous analysis, which communicates userfriendliness
and sustainable development. A cursory investigation was made for choosing a
mobile phone to study. The model W890i from Sony Ericsson was chosen partly because it was
expecting to sell a lot during 2008.
Based on the environmental analysis it was clear that Sony Ericsson has a good chemical policy
comparing to their concurrent. A lot of metals are required for the electronics and the mining has
a big environmental impact. W890i is manufactured in China. There are problems moving the
manufacturing to development countries; the control of the processes is made more difficult and
there can often be a lack of resources and knowledge for dealing with the chemicals in a proper
way. The transportation from China could be more effective. The energy consumption in the user
phase is strongly dependent on the way the mobile phone is used. When it comes to energy
efficiency Sony Ericsson has been focusing on the chargers. A mobile phone is used
approximately for 18 months by the first user and the total life time is about 3.5 years. Only 18%
of the users change their phone because the old one is broken. The recycling of mobile phones
varies a lot both nationally and internationally, but the trend is going towards the industrial way.
The collecting of the phones is a big recycling issue today. W890 is not designed in a good way
for recycling.
Three different concepts were made, all based on different golden rules. They had focus on long
life, recycling and housekeeping. The concepts were presented to a panel of five people with
different expertises. Based on the workshop a final concept was chosen with focus on recycling
and energy efficiency.
A physical model was made in corporation with the company
Ergonomidesign. The model will
be used by Magnus Holmes in his master of science thesis to examine the customer value of
EcoDesign.
