There is a proposal into the EU to add to the RoHS legislation by restricting
all halogenated flame retardants. You can find that proposal here. This
proposal has the support of a number of consumer electronics companies
such as Apple. Here are a couple of Pros and Cons for implementing these
additional restrictions into RoHS:
PROS
· Dramatically simplifies the testing and detection. It is simple to test for Cl
and Br, but much more difficult to determine which halogenated compound
that halogen came from. When restricting only 3-4 halogenated
compounds, one would have to run the simple Cl/Br test and, if Cl or Br
appeared, run costly tests to be certain they didn't come from one of the
restricted compounds.
· Puts all electronics on an even playing field. These companies are often using
"green" marketing to promote their company and/or certain products. There
is no clear way to identify whether on mp3 player is more "green" than
another. It is all on how they spin their "green" efforts. By having legislation,
all companies will be required to take the same actions (at least relative to
the restricted items).
CONS
· There are only a few halogenated compounds that have actually been tested and
determined to have some health or environmental risk. Therefore, a total ban
would restrict materials that pose no risks. Companies like Apple have proven
that electronics can be manufactured without any halogens today. However,
as the technology advances and changes there may be needs or technological
advantages to using certain halogenated compounds but if the law is in place it
will be extremely difficult to change.
· The proposed regulation states to ban all halogenated flame retardants. Exactly
what is a halogenated flame retardant? If there are 10,000 halogenated
compounds, how do we determine which ones are a flame retardant and which
ones are not? Without spelling out specific compounds, individuals will be left
to assess whether or not their halogenated compound could be considered a
flame retardant. This is a particular challenge for solder pastes and fluxes
where halogenated compounds are used but are not intended as a flame
retardant. Would those be banned?
Restricting materials unnecessarily will limit innovation and possibly restrict the
advancement of technology. There is a very delicate balance between protecting
the environment and preventing technology. There are no easy answers.
