“Meet the need of the present generation without
affecting the ability of future generations to meet
theirs.”, according to the Brundtland Report (1987)
E-waste is defined by the European Community (2003)
as an "electrical or electronic equipment that has been
Given as the main causes of the e-waste, the
obsolescences are divided in two:
Though subjects related to environmental
degradation are highly discussed nowadays, e-
waste isn't discussed yet as it should be, if
compared to its power to cause damages.

• Electronic equipments recycling.
Instead of buying a new computer, you change
some parts of it for a new one. It is, therefore, a
Most software advance as obsolescence, that is,
each version requires more powerful computers.
On the other hand, free software have a greater
concern with less advanced hardware. What makes
it functional in more modest computers.
"Solving the E-Waste Problem" - Joint effort
between manufacturers of computer equipment and
telecommunications companies. Aims to create
global standards for the recycling of electronic
scrap, increase the life of electronic products and
develop markets for their reuse.
Eletronical equipments recycling
Encouraging recycling mechanical, chemical and
energy resources, since about 94% of materials
used in eletronical equipments are recoverable.
As an example of implementation of this measure,
we have a project in the Universidade de São Paulo
called: "Projeto de Cadeia de Transformação de Lixo
We conclude that there are alternatives that
attempt to minimize the situation today, but we did
not find a definitive solution. As the prospects for
the future can be exciting, the commitment to this
issue tends to grow.
