Wood Preservative Receives 2002 Presidential Green Chemistry Challenge
(from August 13, 2002)
The U.S. Environmental
Protection Agency has presented Chemical Specialties, Inc. (CSI) the
2002 Presidential Green Chemistry Challenge Award for its environmentally
advanced wood preservative, ACQ Preserve®. CSI developed ACQ (alkaline
copper quaternary) as an arsenic-free replacement for CCA (chromated
Over the past few
years, scientists, environmentalists and regulators have raised concerns
regarding the risks arsenic poses to children who come into contact
with CCA-treated wood in playground equipment, picnic tables and decks.
The wood treatment industry has voluntarily agreed to phase out the
use of CCA for domestic uses over the next few years. The shift will
eliminate the use of 40 million pounds of arsenic and 64 million pounds
of hexavalent chromium each year.
Dr. Henry S. Cole,
president of Cole & Associates who acted as a consultant to CSI,
The phase out of CCA will virtually eliminate the
use of arsenic in the U.S. since 90 percent of the arsenic in this country
is used for CCA." Cole added, "CSI' development of ACQ is
a good example of how a company can reap commercial benefits by addressing
public concerns on the environment."
While ACQ does not
contain arsenic, environmentalists are concerned about its use as a
replacement to CCA. ACQ is a chemical preservative and there
has been limited testing for human health effects. The safest alternative
to CCA treated wood is naturally pest and rot resistant wood which has
been sustainably harvested, such as cedar or redwood.
