Background, aim, and scope A cradle-to-grave life cycle assessment (LCA) of a toy incorporating electric and electronic components is carried out following
the ISO 14044 standard, with the purpose of identifying the environmental hotspots and suggesting ecodesign measures to the
manufacturer.
Materials and methods The product under study is a teddy bear which sings songs and tells stories while moving its body, using conventional alkaline
batteries as a source of energy. This toy is designed by a Spanish company, but manufactured entirely in China, from where
it is exported to Europe, America, and Africa. The LCA study includes production of all components in China, maritime and
road distribution, use phase, and end-of-life. Life cycle impact assessment is focused on five standard impact categories
from the CML 2001 method.
Results The use phase is identified as potentially the most important life cycle stage, due to the impact of battery production. It
is responsible for 50% to 64% of the overall life cycle impact, depending on the impact category. Toy production is also an
important stage, with 28% to 34% of the total contribution. Maritime distribution also involves relevant contributions in
some impact categories. Based on the results of the study, a set of ecodesign measures were suggested to the manufacturer,
with most of them being judged as feasible, and applied in a new product.
Discussion Important data gaps were encountered during the study, especially concerning the use phase, due to lack of data on consumer
behavior, and background inventory data on alkaline battery production. A sensitivity analysis applied to the use phase showed
that the relative importance of this life cycle stage is strongly affected by the assumptions made in this work.
Conclusions The LCA study was found as a very helpful tool to define ecodesign measures for this product. Several measures suggested have
been actually implemented by the manufacturer in a similar product.
Recommendations and perspectives This case study, together with others, will help in the long run to define general ecodesign measures for the toy sector in
Catalonia.

Development of Junction Elements from Study of the Bionics 总被引:1,自引:0,他引:1
The applications of bionic methodology developed by the Laboratory of Design and Material Selection as basis in the creation of junction elements were demonstrated. These elements favor the application of Ecodesign in reference to the effec-tiveness of product dismount aiming the reduction of ambient impact in all its phases of use. The creation,the development and the confection of new junction elements were described,and case studies of new products developed specifically with this purpose were presented. 相似文献
