Is Green a Fad?
  • Economic Sustainability
  • Environmental Sustainability
  • Social Sustainability

Definition of Sustainability
  • Meeting the needs of today without compromising
    the ability of future generations to meet their
    needs.

The Brundtland Commission - 1983

Managing Risk
Historical focus
  • Risk ?(Hazard, Exposure)

8
Control Technologies
  • Gloves
  • Respirators
  • Self-contained breathing apparatus
  • Moon suits
  • Stack scrubbers
  • Waste water treatment

9
Perception of Environment
  • Protecting the environment
  • Costly
  • Restrictive
  • Environmentally friendly
  • expensive doesnt work well

12
Green Chemistry Definition
  • Green chemistry is the design of chemical
    products and processes to reduce or eliminate the
    use or generation of hazardous substances.

Green chemistry is cost-competitive(not pay
more, get less)
13
Green Chemistry and Sustainability
  • Creativity of chemists provides technology
    solutions for sustainability!

14
Green Chemistry Overview
  • Greener synthetic pathways
  • Greener solvents/reaction conditions
  • Designing greener chemicals
  • Inherently safer chemistry
  • Process analytical chemistry

15
Principles of Green Chemistry
  • Prevent waste
  • Maximize atom economy
  • Design less hazardous syntheses
  • Design safer chemical products
  • Use safer solvents and reaction conditions
  • Increase energy efficiency

16
Principles of Green Chemistry
  • Use renewable feedstocks
  • Avoid chemical derivatization
  • Use catalysts, not stoichiometric reagents
  • Design chemical products to degrade after use
  • Analyze in real time to prevent pollution
  • Minimize the potential for accidents

17
Green Good Chemistry
  • Green chemistry is just good chemistry.
  • Why do we need to call it green?
  • Chemists routinely accept hazard that is
    unacceptable outside the lab.
  • What happens in the lab affects everything
    downstream.

18
Why Use Hazardous Chemicals?
  • Dont know the hazard
  • Can handle the hazard
  • Speed/work well
  • Familiarity
  • Necessary to perform function
  • Thats the way weve always done it

19
Why Green Chemistry?
  • Reduce costs
  • Reduced need for capital investment
  • Reduce time to market
  • Encourage investors
  • Minimize unknown future liability
  • Enable new functionality

20
Green Really Means Business Source
Newsweek September 23, 2008 Environmental
concerns haveemerged as a dominant driver of
global corporations, marrying an old impulse to
be good stewards of the planet with an equally
ancient desire to make money. That marriage may
well eradicate the quaint distinction between
profit motive and public good, opening up a
brand-new world of business practices and
investment opportunities.
21
Presidential Green Chemistry Awards
  • High level recognition for outstanding green
    chemistry technologies.

Green Chemistry Peroxide synthesis
  • H2 O2 ?

Anthraquinone working solution reused at high
energy and capital cost.
23
Green Chemistry Peroxide synthesis
  • Bleaching in place of chlorine-based bleaches
  • Propylene oxide formation instead of chlorohydrin
  • H2 O2 ?

H2O2
  • Precise control of catalyst crystal size and
    morphology
  • High selectivity below H2 flammability limit

Battelle - Biobased Toners
  • Bioderived polyester, polyamide, and polyurethane
    resins and toners for office copiers and printers
  • Used soy oil and protein and corn carbohydrates
    as chemical feedstocks
  • Print quality maintained
  • Improved de-inking for recycling copy paper
  • Ink degrades and is easily removed
  • Higher quality recovered materials
  • LCA shows reduced energy and emitted carbon
    dioxide

Poly(lactic acid) from NatureWorks LLC
  • Manufacturing poly(lactic acid) (PLA) from
    renewable resources
  • corn or wheat agricultural waste in future
  • Uses 20-50 fewer fossil fuels than conventional
    plastics
  • The synthesis of PLA produces a high yield, does
    not require organic solvents, and creates no
    hazardous materials
  • PLA products can be recycled or composted
  • PLA resin can be made into fibers, nonwovens, and
    plastics for consumer goods such as
    clothing and food packaging

Green Chemistry Produces Results
  • The 67 Award-winning technologies prevent
  • The use or generation of 193 million pounds of
    hazardous substances, including feedstocks,
    solvents, and waste
  • The use of 21 billion gallons of water
  • The release of 57 million pounds of CO2

31
Green Chemistry Produces Results
  • Through 2006, all nominated technologies
  • Prevent the use or generation of 1 billion pounds
    of hazardous substances
  • Prevent the release of 350 million pounds of CO2
  • Save 21 billion gallons of water
  • Save 9 billion BTUs of energy

32
