PVC misinformation
In the words of Kermit the frog
"It is not easy being green".
The environment is extremely
important, we have only one and
it is necessary for us to make
sure we do not harm it for
ourselves and our future
generations. Greenpeace is a
necessary voice in protecting
our environment, however it
would be more helpful it is was
a voice of reason. One of
Greenpeace and other
environmental organisations
objectives is to ban PVC
products worldwide. The language
they use to convey their message
is often strong and emotive and
somewhat misleading. In this
article we will put forward the
arguments and counter arguments
given by greenpeace and other
organisations.
Greenpeace
Greenpeace have dubbed PVC as
the Poison Plastic. It is the
use of chlorine in PVC
manufacturing that has made
greenpeace give it this name. In
the words of greenpeace "God
created 91 chemical elements,
man more than a thousand and the
devil created one: chlorine."
Greenpeace and its allies argue
that chlorine and all
organochlorines (i.e., compounds
containing chlorine) threaten
wildlife and people. They see an
outright ban as the quickest and
most effective way to improve
environmental quality. Further,
they claim that a "chlorine-free
society" is achievable at modest
economic cost.

Arguments |
Counter- Arguments |
|
PVC is difficult to recycle,
resulting in much of it ending
up in landfills |
The Vinyl2010 recycling
initiative, undertaken
voluntarily by the PVC industry,
is to recycle 50% of
collectable, available PVC waste
from window profiles, pipes,
fittings and roofing membranes
in 2005, and 50% of flooring
waste in 2008

PVC releases remaining VCM (Vinylchloride
monomer) in food and water,
which can cause cancer. |
It turns out that water from
PVC-bottles gives (an
insignificant) 1.9% less cancer,
compared with water from glass
bottles in a mega-experiment.
|
|
PVC can cause infant cot death |
This was incorrect. Although the
exact cause of infant cot death
is not known one of the many
possible causes is the use of
mattresses which catch a lot of
dust. PVC and other plastic
layers prevent that. |
|
PVC can give irritations and
allergic reactions |
It turned out to be the
contrary: a lot of hospitals,
especially built for allergy
patients are using PVC as the
preferred building material,
because a lot of natural
materials like certain types of
wood and not well treated
natural rubber (latex) can give
severe allergic reactions. |
|
PVC softeners, like phthalates,
are linked to cancer and
estrogenic properties |
That may be the case, if you
give massive doses to rats - up
to an equivalent of 500 g/day
for an adult human - but after
hundreds of tests, not for
primates (apes and humans),
because differences in
metabolism. PVC, including
phthalates, is the only
thoroughly tested plastic which
is permitted for blood bags. In
fact, you ingest near 0.1 g of
phthalates per year by using
PVC, the toxic equivalent of
drinking 0.01 g of alcohol...
per year. |
|
Greenpeace is campaigning to
phase out PVC in favour of more
environmentally friendly
alternatives. |
In a study carried out by
National Centre for Business &
Ecology (NCBE) their conclusion
was
"The study team was unable to
find conclusive scientific
evidence linking the production,
use or disposal of PVC compounds
where best industry practice is
utilised to substantial harm to
human health. Likewise
conclusive evidence of serious
environmental harm resulting
from manufacture, use or
disposal undertaken to the
highest standards was not found,
although past and some current
production/disposal falls short
of those standards. Where there
is evidence of harm to human
health or the environment,
evidence that PVCs form a major
factor set against other
processes or products was not
found."
Their comment on the Greenpeace
web site information:
"One problem with the Greenpeace
literature, however, is its lack
of selectivity or of any
critical appraisal. All studies,
ranging the
methodologically-hopeless to
those of the highest quality are
all quoted as if they are
equivalent sources of damning
information on the PVC industry"
|

Governments and industry are
taking action to eliminate PVC. |
In the mid 90's In some European
towns, states and countries a
political ban was voted on the
use of PVC. Several European
towns and states, including
Berlin, Lengerich, The
Netherlands and Belgium are
withdrawing or softening earlier
decisions on banning PVC, after
thorough examination of the
scientific evidence, when
comparing PVC with other
materials on energy use, the use
of non-renewable resources, air-
and water pollution during
manufacturing, use, recycling
and deposit. In all cases PVC
was found to be one of the least
problematic materials.
In the Netherlands, PVC was
(voluntary) restricted for use
in packing, because of the fear
for more dioxins when burned in
incinerators. After thorough
research, this was found not to
be right and the restriction is
lifted now.
In Belgium there was an ecotax
voted on PVC bottles for mineral
water. After two years of
investigation, the scientific
analyses of PVC, PET and glass
bottles didn't give any reason
to exclude one of these
materials on environmental
grounds, so the ecotax is
withdrawn now.
A years long study by the German
Enquete-Kommission of the
Bundestag (the German
parliament) revealed, that there
was no reason to exchange PVC
for alternatives, '...an
exchange of PVC by other
materials is not recommended.
That gives the danger of a shift
of problems, even a possible
worse situation'. A lot of towns
and states in Germany are
reducing or omitting their
anti-PVC-statements now.
In Sweden there was a meeting
between industry, scientists,
politicians and Greenpeace about
the future of PVC. All
scientists present, including
those of the Swedish EPA,
refuted a ban on PVC. Only the
environmental minister stands
behind Greenpeace...
