The Case for Green Chemistry: Integrating Sustainability into Cirricula and Campus

3,500

Published on

Today\'s Generation Next college students are more socially conscious and environmentally aware than
previous generations. Institutions are recognizing their voices and are being encouraged to "do the right thing" regarding environmental
stewardship. While many colleges and universities introduced green building practices into the planning, programming, design, construction
and operation of their campus facilities, we ask an obvious question; why not into the science curricula? Research and experience about the
overall costs and financial benefits of "green" buildings are changing the perception that sustainable design is more expensive. Facts have
consistently shown the benefits of healthier and comfortable environments through increased worker productivity and retention. Can
implementing a "green chemistry" or "green science" curriculum achieve similar results providing increased safety, lower operating cost and
greater flexibility of science lab spaces? Designing Northwestern University\'s new undergraduate Organic Chemistry laboratory required
careful attention to academic objectives, long term flexibility and operational efficiency while providing a safer, more collaborative hands-on
learning environment.

  1. 1. SCUP 42nd Annual International Conference and Idea Marketplace Shaping the Academic Landscape: Integrated Solutions July 8,2007 The Case for Green Chemistry: Integrating Sustainability into Curricula and Campus Presented by: Owen Priest, Director Undergraduate Organic Chemistry Laboratory Program Northwestern University David Hronek, LEED®AP Senior Laboratory Planner Daniel Niewoehner, LEED®AP Associate/Laboratory Planner CUH2A
  2. 2. agenda Sustainability and Chemistry’s Role Introduction to Green Chemistry Case Studies in Green Chemistry Green Chemistry and Academia Evolution of the Green Laboratory
  3. 3. introduction “Chemistry has an important role to play in achieving a sustainable civilization on earth.” Dr. Terry Collins, Professor of Chemistry Carnegie Mellon University
  4. 4. What is a Sustainable Civilization?
  5. 5. let’s consider this issue from several points of view … Global environmental and human health concerns. A stable economy that uses energy and resources efficiently. Social and political systems that lead to a just society
  6. 6. to understand chemistry’s role in sustainability, let’s focus on the first two points… The environment and human health. A stable economy that uses energy and resources efficiently.
  7. 7. in a sustainable civilization… Technologies used in production of needed goods are not harmful to the environment or human health. Renewable resources (such as plant- based substances or solar energy) are used rather than fossil fuels that will eventually run out.
  8. 8. in a sustainable civilization… At the end of their use, materials are recycled if not biodegradable (easily broken down into harmless substances in the environment).
  9. 9. in a sustainable civilization… Manufacturing processes are either designed to not to produce waste products – OR – Waste products are recycled or made biodegradable.
  10. 10. while progress has been made in achieving these goals, there is still a long way to go … Mountains of solid waste are piling up - particularly in industrialized nations. Air and water pollution continues to be problems in many places.
  11. 11. while progress has been made in achieving these goals, there is still a long way to go … Escalating energy consumption and the resulting depletion of fossil fuel resources threatens global economic stability. Global warming from increasing greenhouse gas (GHG) emissions could cause potentially catastrophic climate changes.
  12. 12. let’s look at two converging global events … US oil production peaked in the 1970’s. Since, we have exhausted 75% of all the known oil reserves in the US and are now on our way to consuming the remaining 25%. US peaked in natural gas production in 1973. In order to keep gas production steady in the US, thousands US Crude Oil Production more wells are drilled every Projection year. Very little remaining oil Source: Energy Information Administration, Department of Energy and gas reserves exist.
  13. 13. let’s look at two converging global events … Currently, global warming is at 0.7°C above pre-industrial levels. In order to avoid dangerous climate change, scientists tell us global warming must be kept under 2°C above pre- industrial levels. If we reach 3°C, potentially cause catastrophic climate change Earth’s Surface Temperature could occur.
  14. 14. buildings are the hidden culprit … US Energy Information Administration data illustrates buildings are responsible for almost half (48%) of all energy consumption and GHG emissions annually; globally the percentage is even greater. Seventy-six percent (76%) of all power plant-generated electricity is used just to operate buildings.
  15. 15. herein lies hope for change … Total US building stock equals approximately 300 billion square feet. In the US every year, we tear down approximately 1.75 billion square feet of buildings. Every year, we renovate approximately 5 billion square feet. Every year, we build new approximately 5 billion square feet. By the year 2035, approximately 75% of the built environment will be either new or renovated.
  16. 16. herein lies hope for change … By implementing innovative sustainable design strategies, generating on-site renewable power and/or purchasing (20% maximum) renewable energy and/or certified renewable energy credits we can slow the growth rate of GHG emissions and reverse it to keep global warming under 1°C above today’s levels.
  17. 17. How can Chemistry help us to achieve a Sustainable Civilization?
  18. 18. first, let’s consider chemistry’s benefits… The chemical industry produces many products that improve our lives and upon which we depend.
  19. 19. benefits of the chemical industry … Antibiotics and other medicines Fertilizers, pesticides Plastics Nylon, rayon, polyester, and other synthetic materials Gasoline and other fuels Water purification
  20. 20. benefits of the chemical industry … Although the positive contributions of chemistry and the chemical industry are many, some pollution problems have also resulted. many of these problems can now be solved...
  21. 21. some well publicized incidents over the past few decades… The Cuyahoga River in Cleveland, Ohio became so polluted with chemicals it caught fire in 1969, focusing attention on other US environmental problems and helped pass the Clean Water Act in 1972 A plant accident in Bhopal, India, released methyl isocyanate. Nearly 4,000 people died.
  22. 22. some well publicized incidents over the past few decades… In 1978, some 25 years after Hooker Chemical Company stopped using New York’s Love Canal to dump 21,000 tons of hazardous waste, more than 900 families were forced to leave their homes so that the site could be cleaned
  23. 23. some well publicized incidents over the past few decades… From 1956 to 1962, approximately 10,000 children were born with severe malformations because their mothers had taken thalidomide during pregnancy as a sleep aid and to combat morning sickness.
  24. 24. many countries have enacted laws and ratified international treaties reducing pollution levels ... Montreal Protocol to Protect the Ozone Layer Global Treaty on Persistent Organic Pollutants Rio Declaration on Environment and Development
  25. 25. the pollution prevention act of 1990 This was the U.S. environmental law stating that the first choice for preventing pollution is to design industrial processes that do not lead to waste production. This is the approach of Green Chemistry.
  26. 26. Why is Green Chemistry important in a Sustainable Civilization?
  27. 27. green chemistry works toward sustainability by ... Making chemical products that do not harm either our health or the environment ... Using industrial processes that reduce or eliminate hazardous chemicals, and Designing more efficient processes that minimize the production of waste materials.
  28. 28. The 12 Principles of Green Chemistry 1. It is better to prevent waste than to treat or clean up waste after it is formed. 2. Synthetic methods should be designed to maximize the incorporation of all materials used in the process into the final product. 3. Wherever practicable, synthetic methodologies should be designed to use and generate substances that possess little or no toxicity to human health and the environment. 4. Chemical products should be designed to preserve efficacy of function while reducing toxicity.
  29. 29. The 12 Principles of Green Chemistry 5. The use of auxiliary substances (e.g. solvents, separation agents, etc.) should be made unnecessary whenever possible and, innocuous when used. 6. Energy requirements should recognized for their environmental and economic impacts and should be minimized. Synthetic methods should be conducted at ambient temperature and pressure. 7. A raw material feedstock should be renewable rather than depleting whenever technically and economically practical. 8. Unnecessary derivatization (blocking group, protection/deprotection, temporary modification of physical/ chemical processes) should be avoided whenever possible.
  30. 30. The 12 Principles of Green Chemistry 9. Catalytic reagents (as selective as possible) are superior to stoichiometric reagents. 10. Chemical products should be designed so that at the end of their function they do not persist in the environment and break down into innocuous degradation products. 11. Analytical methodologies need to be further developed to allow for real-time in-process monitoring and control prior to the formation of hazardous substances. 12. Substances and the form of a substance used in a chemical process should chosen so as to minimize the potential for chemical accidents, including releases, explosions, and fires.
  31. 31. What is a Green Synthesis? H3C CH3 COOH CH3 Ibuprofen The Boots company of England patented a synthesis in the 1960s. Has been the method of choice for many years.
  32. 32. Boots Synthesis Step 1 Step 2 O O H3 C H3C H3C COOEt H3C O CH3 CH3 CH3 CH3 CH3 CH3 COOEt AlCl3 NaOC2H5 O O H3 O + Step 3 Step 4 Step 5 H3 C H3 C OH H3C N O Ac2O NH2OH N CH3 C CH3 CH3 H H CH3 CH3 CH3 Step 6 H3O+, D H3 C CH3 COOH CH3 Ibuprofen
  33. 33. Boots Synthesis In the mid-eighties patent on ibuprofen was expiring. The Hoechst Celanese Corporation and the Boots Company agreed to a joint venture, resulting in the BHC Company.

  35. 35. green chemistry means ... Preventing pollution before it happens rather than cleaning up the mess later. Saving money by using less energy and fewer/safer chemicals, thus reducing the costs of pollution control, waste disposal, and space. Eliminating the hazard rather than just preventing exposure.
  36. 36. case studies in green chemistry Reducing lead pollution Putting out fires the green way Safer dry cleaning Buildings that clean themselves
  37. 37. lead pollution has been decreased by ... Replacing lead in paint with safe alternatives, and Replacing tetraethyl lead with less toxic additives (e.g., “lead-free” gasoline).
  38. 38. chemical foams to fight fires Millions of tons of chemical fire-fighting foams used worldwide have discharged toxic substances into the environment, contaminating water supplies and depleting the ozone layer.
  39. 39. putting out fires the “green” way A new foam called Pyrocool FEF has now been invented to put out fires effectively without producing the toxic substances found in other fire-fighting materials.
  40. 40. chemicals for dry cleaning Perchloroethylene (“perc”) is the solvent most widely used in dry cleaning clothing. Perc is suspected of causing cancer and its disposal can contaminate ground water.
  41. 41. a safer method of dry cleaning Liquid CO2 can be used as a safer solvent if a wetting agent is used with it to dissolve grease. This method is now used commercially by some dry cleaners.
  42. 42. buildings get dirty The soiling of a building facade becomes increasingly visible over time. On weather exposed sides, micro- organisms can find an ideal environment for colonization in the form of adequate moisture and nutrients from dirt deposits.
  43. 43. modeled on nature: the lotus effect The great peltate leaves of the Lotus flower (Nulembo nucifera) are extremely water repellent and self-cleaning. Water immediately forms droplets and rolls off a lotus leaf carrying away dirt particles on it, cleaning the surface perfectly. http://www.stocorp.com/allweb.nsf/lotusanpage 37
  44. 44. let the building clean itself! The silicon facade paint Lotusan combines water-repellent properties with a surface micro-structure based on the lotus leaf. The dirt is repelled by water droplets and facades stay dry and attractive. Resists the growth of mold, mildew and algae.
  45. 45. Where does the Transformation begin to a Sustainable Civilization?
  46. 46. green your curriculum while greening the campus ... Green chemistry achieves hazard reduction at all reaction scales, permitting macroscale experimentation using standard laboratory glassware. Green chemistry offers an opportunity to comprehensively upgrade the organic lab curriculum, replacing many classic but perhaps time-worn experiments.
  47. 47. green your curriculum while greening the campus ... Green chemistry provides a unique context for more detailed discussions of chemical hazards and the effects of chemicals on human health and the environment.
  48. 48. green chemistry works toward reducing the risk ... Green chemistry is the utilization of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture, and applications of chemical products. Risk = f(Hazard x Exposure)
  49. 49. green chemistry works by eliminating hazards ... Green Chemistry emphasizes eliminating the hazard rather than just preventing exposure. Control the hazard, no need to worry about the exposure! but is that smart?
  50. 50. green chemistry works to a sustainable future So when Risk = f(Hazard x Exposure) and... Exposure is Half of the Equation then... How do we limit exposure? green chemical experiments in laboratories !!!
  51. 51. going green on campus is more than buildings ... Develop a new course Incorporate green chemistry concepts into existing courses – Classroom – Laboratory experiments Research Extracurricular activities – Student Affiliates – Conferences/symposia – Summer schools
  52. 52. but going green has its image problems ... Pedagogical concerns and tradition Lack of educational materials Overcrowded curriculum Perceived lack of rigor Inertia – no champion
  53. 53. and its academic detractors ... “The curriculum will not train students to work with hazardous materials.”
  54. 54. and institutional naysayer's ... “The curriculum will not teach students what they need to know for admission to graduate school or standardized examinations.”
  55. 55. green chemistry is ... Interdisciplinary – Biology – Economics – Engineering – Environmental science – Ethics Supportive of student interest in environmental issues Less hazardous by reducing lab waste Cost beneficial in terms of space, energy and operation Improving lab safety
  56. 56. however, perception is not reality Traditional* Green** Fundamentals of chemistry + + Practical lab procedures + + Green chemical concepts - + Process chemical concepts - + Waste generation/disposal - + Safety + + Realistic scale and apparatus +/- + State-of-the-art curriculum - + * Late 1800’s, periodically updated with new experiments ** New experiments, designed to illustrate key chemical and green issues
  57. 57. integrating green chemistry is easier than you think ... Replace rather than add course material Modernize curriculum using the latest green chemistry developments Ensure quality through thorough testing Provide a wide range of choices – one size does not fit all. Help others learn from your experience
  58. 58. but sometimes baby steps are needed first before running Host a green chemistry speaker Develop a green chemistry activity with a local school Organize a green chemistry poster session on campus Work with a local company on a green chemistry project Make a current lab experiment greener Design a green chemistry web page
  59. 59. a green chemistry curriculum benefits students by ... Teaching a methodology to rationally analyze/minimize hazards Empowering the use chemistry to solve environmental problems Changing the way chemicals, chemistry and chemists are viewed - quot;Know the hazards, not all chemicals are hazardous”.
  60. 60. a green chemistry curriculum benefits institutions by ... Better preparing graduates for challenges faced by chemistry-related industries Enhancing recruiting and retention efforts – faculty and students Creating opportunities to transform curriculum and facilities Positive public relations and educational atmosphere.
  61. 61. evolution of the green chemistry laboratory Let’s not just remodel the old space, let’s build a new space. A new type of space based on a new science pedagogy. A Green Teaching Space
  62. 62. the University of Oregon Green Chemistry Center Nation’s first Green Chemistry teaching lab established in 1999 (30 students) New Green Organic lab opens in 2001 (48 students)
  63. 63. green chemistry at northwestern university Organic Chemistry curriculum had not been revised in over 10 years. All experiments were conducted on a macro-scale. Lack of space limited student enrollment and class size. Existing majors and non-major labs were 20 years old and in poor condition.
  64. 64. green chemistry at northwestern university Mandate from the Dean tasked faculty to update and “green” the curriculum. A new “track” for majors was to be developed. Existing lab space to be renovated providing greater capacity, collaboration, safety, and energy savings. Green/Environmental Chemistry
  65. 65. tech “d” wing organic green chemistry lab Renovation of 7,000 nsf laboratory space on the 2nd floor of Technological Institute “D” Wing Increase number of student stations to maximize class enrollment Create a hands-on, collaborative learning environment for chemistry majors and non-majors.
  66. 66. tech “d” wing organic green chemistry lab Reduce energy costs and increase safety. Incorporate sustainable design principles Construction Budget / Schedule - $2 Million / 9 Months

  68. 68. tech “d” wing organic green chemistry lab computer rendering
  69. 69. “The layout of the labs has been very effective. Each section is small enough to allow for work with your Teaching Assistant, yet large enough to work carefully and efficiently.”
  70. 70. “I have worked in labs at 3 other universities (Columbia, Clark University in MA, and UMass-Medical School), and this one is by far and away the nicest! I love the whiteboards especially and the decoration on the walls – even though it’s minor, it contributes nicely to the overall ambience. Everything is so well-lit and organized extremely efficiently.”
  71. 71. “The safety showers are in easily accessible locations, even more so than in the general chemistry labs.” “The reagent and waste hoods are separate from the hoods used for working, which I feel is safer.”
  72. 72. tech “d” wing organic green chemistry lab Increased number of student stations from 43 to 75; maximizing class size and enrollment Number of fume hoods remained the same. Optimized air flow to support lab; from two (2) 50,000 CFM units to one (1) 50,000 CFM unit.
  73. 73. tech “d” wing organic green chemistry lab Occupied/unoccupied operational mode for student hoods and lighting controls for energy conservation. Use of sustainable materials and finishes. Construction Budget / Schedule – On time + on budget
