Chemists Must Place a Major Focus on
the Environmental Consequences of
Chemical Products and the Processes
by which these Products are Made.
We must consider our
chemical
ecological footprint.
GREEN CHEMISTRY
• Green Chemistry, or
sustainable/environmentally benign
chemistry is the design of chemical
products and processes that reduce of
eliminate the use and generation of
hazardous substances
• Minimize:
– waste
– energy use
– resource use (maximize efficiency)
• utilize renewable resources
GREEN CHEMISTRY
• "Green chemistry represents the pillars
that hold up our sustainable future. It is
imperative to teach the value of green
chemistry to tomorrow's chemists."
Daryle Busch, President ACS, June 26, 2000, “Color Me Green”
Chem. Eng. News 2000, 78 (28) 49-55.

ENVIRONMENTAL
CHEMISTRY
• Poster/Oral Presentation on one of the
PGCC Award Winning Proposals 1996
Cann, Michael C., J. Chem. Ed. 1999, 76 (12), 1639-1641.
REAL-WORLD CASES IN
GREEN CHEMISTRY
• ACS/EPA Green Chemistry Educational Materials
Development Project, 1998
• Compilation of materials on real-world green
chemistry (based on PGCC) in a format that can
be used for educational purposes
• Each case acts as an informational
resource for instructors to use in
greening their courses

MAINSTREAMING GREEN
CHEMISTRY
• Insertion of green chemistry into
mainstream chemistry courses
• Need faculty who teach these courses to
develop modules on green chemistry related
to topics already covered in their course
• Make it easy (lower E act ) for other
faculty to do the same;
place materials on the web

GREEN CHEMISTRY
MODULES FOR SPECIFIC
CHEMISTRY COURSES
• General -Surfactants for CO 2
• Organic -Atom economy
• Inorganic –Activators of hydrogen
peroxide for green oxidation
• Biochemistry –Confirm, Mach 2 and
Intrepid pesticides
• Advanced Organic –Elimination of
Chlorine in NAS
GREEN CHEMISTRY
MODULES FOR SPECIFIC
CHEMISTRY COURSES
• Polymer –Polyaspartic acid
• Industrial –Petretec polyester regeneration
• Environmental –Sea-nine antifoulant
• Chemical Toxicology –Confirm,
Mach 2, and Intrepid

Green Chemistry
–Environmental Chemistry
• Ozone hole and troposheric air pollution: carbon dioxide as a
replacement for CFCs and hydrocarbon blowing agents;
surfactants for carbon dioxide so that carbon dioxide can be
used to replace VOCs.
• Pesticides: readily biodegradable marine antifoulant as
replacement for tributyltin oxide; selective pesticides as
replacements for broad spectrum pesticides.
• Toxic organic chemicals (e.g. dioxins): activators of hydrogen
peroxide to replace chlorine bleaching agents.
• Polluted water and sewage treatment: biodegradable scale
inhibitors and dispersing agents as a replacement for
polyacrylate polymer.
• Solid waste, landfills and closed loop recycling: Petretec
process for conversion of PET back into its monomers and
reformation into virgin PET.
Environmental Chemistry
Baird & Cann
• Introduction to Green Chemistry –Atom
economy; synthesis of ibuprofen.
• Ozone –CO 2 as a blowing agent; Harpin as a
replacement for methyl bromide fumigant.
• Tropospheric pollutants –CO 2 surfactants.
• Greenhouse gases –scCO 2 in
photolithography.
• Energy/petroleum –biodegradable polymers
from renewable resources.
• Pesticides –selective pesticides; termite control/
reduced risk pesticides.
Environmental Chemistry
Baird & Cann
• Toxic organics –non-chlorine bleaching agents,
H 2 O 2 activators
• Water pollution/purification –enzymatic
preparation of cotton textiles; biodegradable
chelating agents
• Heavy metals –removal of lead from automobile
paint; removal of arsenic and cadmium from
pressure treated wood
• Solid waste –biodegradable antiscalant;
recylable carpeting
