GENERAL
SUBJECT
:
Copper
in
Wastewater
Discharges
from
the
Printing
and
Publishing
Industry
TOPICS
DISCUSSED
AND
ACTION
TAKEN
I
called
Ms.
Janet
Schmidt
to
discuss
the
sources
of
copper
in
printing
and
publishing
wastewater
discharges.
Quebecor
World
Buffalo
Inc.
is
one
of
the
top
5
copper
dischargers
based
on
information
from
the
TRI
database.

Ms.
Schmidt
explained
that
copper
in
wastewater
discharges
comes
mainly
from
the
copper
plating
operation
in
the
gravure
printing
process.
Rinsing
and
polishing
after
plating
releases
copper
into
the
wastewater.
She
added
that
other
sources
of
copper
releases
include
copper
in
printing
inks
(
especially
blue
and
green
pigments)
which
goes
to
sludge,
and
recycled
copper
plated
printing
cylinders,
where
copper
is
removed
and
is
sent
for
recovery.
She
also
informed
me
that
concentrations
of
copper
in
the
wastewater
are
estimated
through
back
calculation
based
on
the
amount
of
copper
in
the
filter
cake
and
the
efficiency
of
the
pretreatment
system.

Ms.
Schmidt
estimated
wastewater
discharges
to
be
approximately
175
pounds
per
year,
based
on
2003
TRI
data.

Quebecor
Buffalo
performs
rotogravure,
flexographic
and
lithographic
offset
printing.
