Abstract: The life cycle assessment of the mobile phone housing in Motorola
(China) Electronics Ltd. was carried out, in which materials flows and
environmental emissions based on a basic production scheme were analyzed and
assessed. In the manufacturing stage, such primary processes as polycarbonate
molding and surface painting are included, whereas different surface finishing
technologies like normal painting, electroplate, IMD and VDM etc. were
assessed. The results showed that housing decoration plays a significant role
within the housing life cycle. The most significant environmental impact from
housing production is the photochemical ozone formation potential.Environmental
impacts of different decoration techniques varied widely, for example, the
electroplating technique is more environmentally friendly than VDM. VDM
consumes much more energy and raw material. In addition, the results of two
altemative scenarios of dematerialization showed that material flow analysis
and assessment is very important and valuable in selecting an environmentally
friendly process.
