The Green Chemistry & Commerce Council Education Group is proud to announce the launch of the Safer Chemistry Training for Businesses. This free online curriculum is comprised of educational webinars, ranging from introductory to advanced, and supplemental reading materials. While the material has been developed with a business audience in mind, we hope that other groups, such as technical assistance providers and students, will also benefit from this foundation in green chemistry.

 

The Safer Chemistry Training was developed in response to our member companies' needs for education of their employees and supply chains in various aspects of green chemistry. It is a direct outcome of the GC3 Policy Statement on Green Chemistry Education, which calls on businesses and academic institutions to support and implement green chemistry training in order to fulfill societal and industrial needs.

 

The Safer Chemistry Training for Businesses is designed to be tailored to the specific needs of the learner’s job description and experience; the number of webinars watched and duration of training can be altered as needed.  For example, a purchaser trying to understand new corporate sustainability initiatives might only watch a few, whereas a chemist new to green chemistry might want to watch 5 or 6.

 

View the complete list of educational webinars here. Additional training webinars are planned and will be added to the Safer Chemistry Training in the coming months. Sign up for the GC3 newsletter to be notified of new additions. If you have questions or feedback, feel free to contact Saskia van Bergen.

BIOTECHNOLOGY ON THE RADAR

 

A few years ago, a report published by WWF concluded that industrial biotechnology has the potential to save the planet up to 2.5 billion tons on CO2 emissions per year - more than Germany’s total reported emissions in 1990 - and support building a sustainable future. Industrial biotechnology could help create a true 21st century green economy, as the WWF report states (1).

 

In 2013, industrial biotechnology became extremely visible on the political agenda with the EU Commission proposing a €3.8 billion Public Private Partnership (PPP) on Biobased Industries (2), in order to accelerate the commercialization of biobased products in Europe. The European Commission will invest €1 billion and industry €2.8 billion, from 2014 to 2020, to boost market uptake of new biobased products that are “made in Europe.”

 

The UN agrees that biotech is key to solving the world’s toughest human challenges. We have also seen China make biotechnology a priority in its recent five-year plan. Industrial biotechnology applications are widely used in everyday life by people all over the world – and have been for years. They help reduce the amount of time needed to bake fresh bread, help us to produce fuel from corn and waste materials and save heat in laundry washing. In this way, biotechnology helps to replace chemicals and it offers a way to produce more with less energy and fewer raw materials.

 

FEEDING AND FUELING THE WORLD

 

One of the companies delivering biotechnological solutions is Novozymes, the world’s biggest producer of industrial enzymes as well as microorganisms, and the solutions provided by Novozymes are very much focused on feeding and fueling the world. Feeding the world is critical and an area in which Novozymes is fully engaged. According to UN researchers, demand for agricultural output is projected to grow by at least 70% by 2050. For this reason, Novozymes has engaged in a strategic alliance with Monsanto.

 

Naturally occurring solutions such as microbials, plant extracts, beneficial insects and other organic material will allow farmers to improve crop health and productivity. The collaboration between the two companies plans to transform research and commercialization of environmentally friendly microbial products that will provide a new platform of solutions for growers around the world.

 

To do so, Novozymes is establishing a new RH&D center in North Carolina dedicated to its bioagriculture business. Scientists at the new site in North Carolina will research and develop beneficial microorganisms found in the soil. The resulting technology will focus on improved crop yield, fertility and pest control for growers around the world. The significant expansion of R&D resources will enable Novozymes’ scientists to pursue an increased number of, as well as improved, biological solutions for the ever-changing challenges facing global agriculture.

 

Biotech is also certainly helping to fuel the world. Using biological processes such as fermentation and harnessing biocatalysts such as enzymes, yeast and other microbes to produce biofuels, we can reduce the use of petroleum, water and energy and reduce waste. Right now, biomass conversion is emerging and the technology is consistently developing to make production of cellulosic ethanol more cost-efficient and commercially viable.

 

Novozymes has partnered with Beta Renewables to demonstrate 2G, or second generation, technology on a commercial scale. 2G technology uses fuels that are manufactured from various types of biomass, and the Crescentino plant in Italy has an annual production capacity of 40,000 metric tons. The plant uses wheat straw, rice straw and arundo donax, a high-yielding energy crop grown on marginal land.

 

SUSTAINABLE SAVINGS ADD UP

 

Under these headlines, Novozymes supply enzymes for five major global industries: Household Care, Food & Beverages, Bioenergy, Agriculture & Feed, and Technical & Pharma. Use of enzymes in each industry will provide environmental benefits. Enzymes used in laundry can replace surfactants in the detergent and work to reduce the washing temperature is minimized. Life cycle assessment is used to compare the environmental impact of enzyme production with the avoided impacts obtained by surfactant saving and reduced electricity production for heating wash water.

 

At first sight, the use of enzymes in laundry is not something that one would believe would have significant environmental effects. Doing laundry is one of the activities that consumes the most energy in an ordinary household. By washing at 30°C rather than 60°C or 40°C, the CO2 savings potential in Europe and the U.S. is around 32 million tons – equivalent to emissions from 8 million cars. At the same time, enzymes have the potential to replace up to 50% of surfactants, while maintaining cost and washing performance. If all Europeans washed their clothes using cold water, it would be possible to close three large coal-fired power stations, reducing the continent’s CO2 emissions by 12 million tons a year.

 

BIOTECHNOLOGY TO COMBAT CLIMATE CHANGE

 

Many of these biosolutions come together and offer improved environmental performance for customers compared with conventional technologies. Not only does this result in higher-quality products at lower costs, it also enables our customers to reduce their CO2 emissions. Lower CO2 emissions help reduce the stress on our global climate and support the mitigation of climate change.

 

For 10 years, Novozymes has conducted peer-reviewed Life Cycle Assessment (LCA) studies to document the environmental impact of its biosolutions (3), and we develop specific claims together with our customers. We specifically advise our customers and partners on ways to reduce their CO2 emissions and leverage the positive impact on climate change that our products enable. We estimate that our customers avoided 60 million tons of CO2 emissions in 2014 by applying our products, the equivalent of taking approximately 25 million cars off the road. This is an increase of 8 million tons compared with 2013, and was driven primarily by increased sales and performance of our solutions for biofuels, household care and textiles. To give one example: In 2014, we conducted a comprehensive study (including an LCA and a consumer survey) to better understand and document how Novozymes’ patented biopolishing solutions can improve the quality of cotton clothing and extend its lifetime.

 

By using our biopolishing solutions, customers strengthen their brand and gain premium-pricing opportunities, fewer garments go to waste, and resource efficiency increases throughout the garment production chain. The study documents that our biopolishing solutions could potentially be applied in 40% of the world’s annual cotton production, and result in savings of approximately 24 million tons of CO2 emissions and 27 billion m3 of water. The study will be published in 2015.

 

SUSTAINABILITY IN THE DNA

 

Building on biotechnology, sustainability is an intrinsic part of the business for Novozymes. It is the nature of our technology and the technology comes from nature itself. Sustainability is fully integrated into Novozymes’ business and drives innovation for the company. In 2013, Novozymes was ranked as the most sustainable company in the Biotechnology Industry category of the Dow Jones Sustainability Index for the 12th time. At Novozymes, sustainability is a business driver on three levels; 1) To operate responsibly, 2) To grow our current business, and 3) To develop new business. Through working responsibly, we strive to live out what we believe in and constantly challenge ourselves to optimize our business practices and improve our sustainability impact.

 

SUSTAINABILITY NEEDS TO BE COST COMPETITIVE

 

The generally positive sustainability impact of Novozymes’ solutions helps to grow the current business; the solutions enable the customers to meet their sustainability agendas through optimizing their use of raw materials and energy. Customers like what is offered by biotechnology, however, enzymes used in detergent need to be cost-competitive and better performing than the chemicals they replace. “Consumers are really excited about low temperature detergents because that translates to immediate savings on their electricity bills,” Peder Holk Nielsen explained in an interview with Forbes (4). But he also explained that most consumers aren’t willing to pay for those savings. When you look at the positioning of products as renewable or having a lower footprint, the big companies share data that roughly suggests that a lot of consumers would never buy a product that has a green label because they are suspicious of its performance.

 

STRATEGY ON SUSTAINABILITY

 

Nevertheless, even though end users don’t seem willing to pay for sustainable savings and that sustainability has somehow faded from the global agenda, Novozymes has made it an integral part of its business – and has done so for years. To emphasize this, in 2015 Novozymes presented a renewed strategy with the headline of: “Together we find biological answers to better the growing world – let’s rethink tomorrow”.

 

Novozymes’ renewed strategy is also very specific and has a number of sustainability targets:

 

  • REACH six billion people with our biological solutions
  • EDUCATE 1 million people about the potential of biology from 2015-2020
  • CATALYZE five global partnerships for change from 2015-2020
  • DELIVER 10 transformative innovations from 2015-2020
  • SAVE 100 million tons of CO2 by 2020

 

THE BIOBASED SOCIETY

 

To protect the world from the devastating effects of climate change all relevant technologies need to be put to use. Biotechnology is in use today and interest for the technology is increasing for good reasons. Today the world runs on fossil fuels; and we all know that this has high and long-term costs for our planet.

 

Biotechnology is a way to use renewable biomass as the most important raw material, enabling the production of the same products we get from oil today. A change from an oil-based economy to a biobased economy means a future where biorefineries replace oil refineries, and biological raw materials replace fossil fuels as the primary feedstock for materials, fuels and energy. The best news is that we have the technology ready here today – it is called biotechnology.

The word is out. Green chemistry has caught on, and the field has grown tremendously since it first emerged in the 1990s. The question now is where are we going with all this momentum?

 

On September 18, 2015, we took an important first step in the roadmapping project for green chemistry. We hosted a visioning workshop with a small group of participants deliberately selected for their diverse perspectives on green chemistry. This step will catalyze additional workshops, meetings and full drafting of the roadmap plan.

 

TIMG_0042.JPGhe workshop was marked by the group’s optimism, but also by their earnestness to create a high-quality, durable and effective plan. They were tasked with setting the vision for the roadmap: the elements of the vision, the role of the roadmap, how to best engage the community, and next steps in the project. All of this in the context of the remarkable progress that has been made in green chemistry already.

 

Perhaps the most difficult task, however, was suspending disbelief for the sake of aspiration: believing in a future of technologies, chemistries, and innovations that now seem impossible. The group looked at roadmaps from other communities as models that provided insight into how to build a successful roadmap for green chemistry.

 

Preliminary results from an ACS GCI survey of hundreds of chemistry educators were also discussed.  It generated conversation about the state of chemistry education. Although the workshop participants acknowledged that academic reform is typically a slow process, they imagined a future state in which academic and industry leaders have collaborated to develop a chemistry education with green chemistry fully integrated. Already, the survey responses have shown that most chemistry educators are including topics like chemical hazards and exposure in their teaching.

 

The workshop was dotted with broader hopes for green chemistry as well. For example, how green chemistry has the ability to eliminate a wide array of social injustices. Or, how it enables interdisciplinary approaches that lead to innovation. The practice of chemistry was discussed as something in evolution, becoming ever-more benign and evaluated through systems-thinking. As the meeting drew to a close, participants enthusiastically volunteered to take on responsibilities and to continue to work towards a shared vision.

 

With green chemistry, chemists and engineers can know that they are doing the best science, with the best ethics, for the best future.  We’ll need input from you, the community, as the roadmap progresses. Keep an eye out for updates and opportunities to contribute. We can’t wait to see where the path will take this community.

I’m currently writing this on a plane as I make my way to Illinois to speak at the Midwest Association of Chemistry Teachers at Liberal Arts Colleges (MACTLAC). I’m honored and excited to be asked to these kinds of events for several reasons. The first is, the data we’ve gathered suggests that teachers at these institutions are doing more than many other chemistry teachers to integrate green chemistry and engineering concepts into their curriculum. I think this is huge because at most R1 universities, teachers of chemistry are resistant and often antagonistic to the notion that teaching chemistry within a real-world context is important. The more I can do to encourage a change in how chemistry is taught, the more hope I have that society can and will change some of the less sustainable practices we take for granted as just “the way we do chemistry.” I often quip that if there isn’t an explosion, a fire, chemistry in a glove box, liberal quantities of liquid nitrogen, or a reaction at 1000+ C, then most chemists don’t think they’re doing real chemistry.

 

The second reason is that I get to talk about our educational roadmap initiative. For those who have not yet heard about this, I would invite you to have a look here. We are deeply indebted to our leadership team, Dr. Jim Hutchison, Professor of Chemistry at the University of Oregon, Dr. Mary Kirchoff, the ACS Director of Education, and Dr. Eric Beckman, Professor of Chemical Engineering at the University of Pittsburgh, and to our ACS GCI Program Manager, Jenny MacKellar, for shepherding this initiative over the past year. During September, the ACS GCI invited a group of leaders in green chemistry and green chemistry education to a visioning workshop that will be followed next June, 2016, by a larger workshop of green chemistry leaders and educators. The purpose of the second workshop is to build on the visioning workshop and develop a roadmap for green chemistry education.

 

There were several insights developed at the workshop that are worth mentioning. The first is that developing accepted learning objectives for green chemistry in all areas of chemistry curriculum will be enormously challenging. The second is that in order for the second workshop to be successful, it will be essential to build out some of the visions that were created as part of the workshop. These visions have to do with the practice of chemistry, the pull for chemists by industry, what students need to know, and how to move chemistry curriculum forward. Anyone who is part of the chemistry education sector, and those that have come through it, know exactly how hard it is going to be to move this roadmap forward. This is not to say that there hasn’t already been a lot of great work by some chemistry educators who have made great progress down the path of integrating green chemistry and sustainability concepts into their curriculum. There are, but I think that it is fair to say that this has not been done in a consistent or standardized manner.

 

I can’t emphasize enough how important and pivotal I think this initiative is to the future of the global chemistry enterprise. I hope all who are reading this recognize the magnitude of this challenge and I am equally hopeful you recognize that the ACS GCI, or those that are part of the workshops and working parties, will not be able to do this by themselves. This is a multi-year effort that will require the hard work of many dedicated people to be successful. We’ve just drawn the line in the sand, and we need every one of you to help us move the chemistry enterprise forward towards more sustainable practices.

 

It is possible to do this, but it won’t happen on its own, overnight. Thanks for doing your part to make this happen.

 

As always, please do let me know what you think.

The list of companies joining the race towards sustainable rubber is growing. From startups to global chemical manufacturers, there’s a widespread push to develop high quality rubber that isn’t sourced from petroleum. Fluctuating oil prices, growing pressure to be sustainable, and virtually no domestic means of producing natural rubber are all fueling the search for a reliable, long-term solution.

 

Natural rubber and synthetic rubber each have their pros and cons. For example, most of the world’s natural rubber comes from Hevea brasiliensis plants, often called rubber trees, in Southeast Asia. This means there’s little to no geographic diversity in where natural rubber is sourced. On the other hand, natural rubber offers unequaled properties such as its ability to reinforce tires under the pressure of trucks and airplanes (Tullo).  New technologies for producing rubber focus less on which type is “better” and more on how to make the production of durable rubber more sustainable, efficient and cost-effective.

 

Natural Rubber

 

11055-guayule-plants-pv.jpgAlternative plant sources of rubber are gaining traction, and a little desert shrub has garnered lot of press. On October 1st, the Bridgestone Corporation announced the first-ever tires made entirely from guayule-sourced rubber. The guayule plant is native to the southwestern United States and northwestern Mexico, and this renewable source is being grown commercially for its 5-10% natural rubber content (cis-1,4-polyisoprene) (Tullo).  The ability to grow the plant in the U.S. is significant; it offers a uniquely local solution to natural rubber.

 

The percentage of latex in guayule is low; moreover, much of the plant, and therefore the resources that go into growing the plant, becomes waste. Yulex Corporation, a small company in Arizona, hopes to change that. Yulex has an extensive guayule breeding program and plant genomics research facility, projects enabled in part by a $6.9 million U.S. Department of Agriculture Grant (Fikes). Their hope is to use these tools and advancements in biotech to improve the plant’s rubber yield, making the harvesting process more efficient and cost-effective (Metz).

 

Guayule isn’t the only plant that’s being bred for rubber production. At the Fraunhofer-Gesellschaft, dandelions are being investigated for their natural latex output, but they aren’t expected to provide the world’s supply of rubber by themselves. Like hydroelectric, geothermal and other sources are combined to provide renewable energy, dandelions could play one part in sustainably meeting the world’s growing demand for rubber.

 

Synthetic Rubber

 

Even with a wider variety of natural sources, there is still a need for synthetic rubber which is used in a range of products from shoes to medical equipment. Perhaps the most exciting development in synthetic rubber is the role biosynthesis might play in its production. A partnership between LanzaTech, a biotech firm, and a global polymer and fiber producer, INVISTA, could drastically change how synthetic rubber is made.

 

Butadiene is a key intermediate in the production of synthetic rubber and nylon. Rather than sourcing it from petroleum, this collaboration focuses on an innovative alternative: biotechnology that converts industrial waste gases like carbon monoxide into valuable butadiene. INVISTA and LanzaTech plan to commercialize this biosynthetic route to butadiene early next year. Not only does this technology enable renewable intermediates to synthetic rubber, it also creates value from what would otherwise be waste.

 

As with any industry, it’s exciting to see companies innovating to be more sustainable. With new tools, facilities and emergent biotech to develop alternative materials and renewable sources, rubber manufacture – a seemingly unlikely field – seems headed toward a much greener future.

Since the dawn of civilization, natural materials have been a fundamental part of human life and environment. However, in the 20th century, due to exploitation and high cost of natural resources, synthetic materials replaced natural materials. Recent advances in biotechnology and materials science have allowed the invention of eco-friendly materials that can be produced easily from sustainable resources in a broad array of useful applications including textile, cosmetic, and medicine. Proteins are key to the creation of many new, high strength materials.

 

Proteins have several advantages as natural materials: their chain length, sequence and stereochemistry can be easily controlled, (ii) the molecular structure of proteins is well defined (e.g., secondary, tertiary and quaternary structures), (iii) they provide a variety of functional chemistries for conjugation to other biomolecules or polymers, and (iv) they can be designed to obtain optimum physical properties. Proteins can be roughly divided into three classes (i.e., globular, membrane, and structural) according to their environmental conditions. Globular proteins are water soluble and provide a wide range of critical biological functions, for example, the enzymatic catalysis of chemical reactions. Membrane proteins, on the other hand, reside in hydrophobic environments and help signaling processes of cells. Structural fibrous proteins form highly hydrogen-bonded regular structures. Many fibrous proteins have been extensively studied such as elastins, collagens, silks, keratins, and resilins.

 

Squid have teeth-like structural protein inside their suckers, which serve for holding a diverse array of objects strongly. A book published by Williams a century ago in 1910 entitled ‘‘Anatomy of Squid’’ studied the squid arms and tentacles in detail but incorrectly claimed that the SRT is a chitin-like substance9. Four decades ago, Nixon and Dilly studied the SRT and published an article1 in 1977, correcting the earlier mistake, which concluded that SRT is a protein complex. Moreover, they demonstrated that SRT has submicron pores. Recently, mechanical and thermal properties of SRT have been studied to demonstrate that the porous structure is important for compliance under high forces2, and rubbery thermal transition provides strong under water adhesion3.

Picture1.png

 

SRT protein exhibits an unusual and reversible transition from a solid to a rubber4, and can be thermally shaped into any 3D geometry (e.g. fibers, colloids, and thin films). Using the tools of molecular biology, large-scale computation, and mechanics, it has been demonstrated that these proteins have excellent mechanical, structural, and optical properties, in wet and dry conditions that exceed most natural and synthetic polymers5. Figure 1 shows a recombinant SRT fiber that is flexible and strong. This protein is a perfect candidate in textiles as well as a myriad of other materials in high demand. These materials range from disposable medical garments to fabric scrims for composites to commodity clothing items for potential use in textile applications. The thermal recyclability of the SRT can be exploited by molding it into nanotube arrays or micron size colloids. SRT has also been adapted for use in the artificial reconstruction of a Manduca sexta wing6. Utilizing structural proteins to accurately imitate insect wing characteristics opens the door for next-generation biomimicry, specifically in the area of mimic flapping-winged animals. With their tunable flexibility (1-10^3 MPa) and ultra-high thermal expansion coefficient (>500 10^-6 °K-1) structural proteins are also ideal candidates for optical devices. For example, optical lenses made from SRT would have great interests due to its transparency, flexibility, biodegradability, biocompatibility and molecular level structural tunability that cannot be achieved by rigid inorganic materials4.

 

                                       

 

We were able to cut a SRT sample in half and repair it by applying pressure and warm water as seen in the video above. SRT’s supramolecular chemistry provides self-assembly to achieve stiff self-healing morphology with soft/hard domain separation7. Segmented structure of the SRT protein shows soft segments with self-healing capability and hard beta-sheet segments that crosslink the structure. The ring teeth of squid was collected around the world -- in the Mediterranean, Atlantic, near Hawaii, Argentina and the Sea of Japan -- and it was found that proteins with self-healing properties are ubiquitous8. The underlying mechanism for self-healing is the protein’s ability to deform and soften in water above its rubbery temperature, while maintaining the hydrogen bonds reversibly7. Self-healing structural proteins provide not only high strength polymeric materials but also will help discovery of novel properties for clinical applications such as orthopedic devices for repair, and biodegradable gels for wound healing in the near future.

Beyond solving an obvious energy dilemma, curbing our societal need for petroleum will also require finding alternative materials for a sustainable future. When filling up at the gas pump or heating our homes with oil we often consider how we’re tapping into a dwindling supply of fossil fuels. We often forget, however, that many of the advanced materials in use today are sourced from the same feedstock. Manufactured items not made from metal, glass, wood, ceramics, wool or cotton most likely come from petroleum: plastic bottles, bags, panels, casings, countertops, fabrics and much, much more.

 

If feedstock sourcing were the only concern, economic drivers would steer the market toward biorenewable alternatives once their price dropped below that of extracting and processing crude oil. Unfortunately, the fate of our petroleum materials and fuels represents an equally daunting concern. The net increase in atmospheric CO2 as a result of burning fossil fuels contributes to global climate change, and the environmental persistence of many petroleum derived materials leads to widespread and long-lasting pollution. We could be faced with a future where even after we've stopped pumping oil, evidence of these practices remain in the form of an irreparably altered climate and undegraded plastic trash still circulating in the oceans or clogging landfills.

 

In an attempt at more sustainable products, researchers more and more turn to materials sourced from renewable feedstocks and that persist in the environment on a time scale no longer than their useful lifespan. Toward these goals biodegradable plastics from petroleum have been made, as have non-biodegradable, exceptionally durable plastics from biomass. As both a biodegradable and biomass-sourced polymer, the bioplastic polylactic acid (PLA) is gaining mainstream acceptance as a sustainable material. Significant synthetic effort still goes into PLA production: lactic acid must be generated and isolated from corn or potatoes before its derivatives can be polymerized to form PLA. Circumventing the need for such involved processing techniques, some useful polymers can be derived directly from biomass. By feeding sugars to the right microorganisms, we can encourage them to produce polyhydroxybutyrate (PHB), which we can then extract and use directly. Rather than having engineered microorganisms build polymers for us, we can source them from organisms that would have otherwise built the polymers anyway.

 

The biopolymer chitin, the structural component of marine crustacean shells, insect cuticle, and found in many other biological organisms, offers an excellent strength profile from a materials standpoint. A recent report from the Weiss Institute at Harvard demonstrated the generation of large-scale functional objects such as cups, clips, chess pieces, and egg cartons from chitosan, a derivative of chitin, by dissolving the polymer in 1% acetic acid/water and carefully controlling the evaporation of liquid. Adapting their laboratory procedure for use in K-12 outreach sessions, in collaboration with Beyond Benign we similarly dissolved both chitosan and chitin in vinegar, poured the solution into silicone ice cube trays (molds) and let the liquid evaporate by placing the molds on a seedling heating mat.

 

By engaging young students in sustainability-focused outreach, we hope to inspire the next generation of scientists to develop materials that are both sourced from biomass and fully biodegradable.

Before arriving at Saint Francis University (SFU), many of our Chemistry Club members have never heard of green chemistry, but it doesn’t stay that way for long. Green chemistry is an integral part of the SFU lab culture. For the majority of the Chemistry Club members, our initial exposure to green chemistry was in our very first laboratory activity of general chemistry. Along with the safety introduction, the instructor outlined the Principles of Green Chemistryi  and we completed an activity using M&Ms to learn about E-factorii . Most of the SFU faculty also practices green chemistry principles in their own research labs. Their focus has been on using less toxic chemicals and producing less waste. While green chemistry was practiced in the laboratory, we, as a club, had a difficult time distinguishing green chemistry practices from sustainability.

 

At the 2015 ACS National Meeting in Denver, CO, we watched other Green Chemistry Student Chapters receive their awards, but we could only observe since we didn’t earn it that year. The club was upset, and we didn’t understand why we hadn’t received an award for green chemistry. Upon returning to campus and reviewing the Green Chemistry guidelines on the ACS website, we realized that our aim was off target; we had been focusing on sustainability activities and not green chemistryiii . While performing sustainability activities, such as checking the water quality of a local lake, are commendable community activities, they do not teach or train someone how to develop less wasteful methods in the chemistry laboratory.  In order to earn a Green Chemistry award, a chemistry club must ensure that the activity is directly connected to one of the 12 Principles of Green Chemistry or the Design Principles of Sustainable & Green Chemistry and Engineering. Green chemistry awards focus on lab practices and educational outreach on Green Chemistry principles while sustainability initiatives focus on activities such as environmental monitoring or road cleanups. Using the information from the ACS GCI, we were able to focus our chemistry club activities towards the Green Chemistry guidelines – and hopefully earn some Green Chemistry awards!

 

Dr. Rose Clark.jpgTo begin the academic year in the spirit of green chemistry, the faculty and students signed an online green labs pledge to uphold the principles of green chemistry in our labs and to do their very best in promoting green chemistryiv . We also completed a SFU department and school Green Chemistry Commitment. The Commitment was a document stating that the Saint Francis University Chemistry Department would follow the principles of green chemistry and ensure that each laboratory used green chemistry as much as possiblev . The agreement was signed by Dr. Rose Clark, the Chemistry Department Chair, and Dr. Charles MacVean, Dean of the School of Sciences.

 

Another major project that our student chapter has worked on is a green chemistry poster. The poster was created by the four chemistry club officers and enhanced by asking faculty where they apply green chemistry principles in their everyday activities and incorporating their comments.  Overall, our poster outlined the 12 Principles of Green Chemistry in a fun and creative format and included ways in which Saint Francis University upholds green chemistry principles. Our poster will be mounted outside the laboratories as a reminder of our pledge to green chemistry practices.

 

Our green chemistry practices at Saint Francis University are extremely beneficial to the SFU students, as they enable us to be better chemists. Green chemistry is guiding us to complete experiments with safer alternatives, eliminating unnecessary chemical waste and reducing our energy consumption. We are producing less waste and saving money. More than anything, green chemistry is teaching students at Saint Francis University to do more with less.

Light Inquiry: Molecules, Light, and Natural Dyes

 

Research Questions:

 

What procedure would be suitable for extracting β-carotene from carrots?  How can you determine how much β-carotene was extracted?

 

Learning Goals:

 

In this lab, you will design an experiment to extract β-carotene from carrots and determine the concentration of the resulting solution using visible spectroscopy and Beer’s Law. You will examine how changes in sample concentrations result in changes in absorbance and transmission. You will also be using a spectroscope to explore the interactions of light and matter.  This will help you to understand light, transmission, reflectance and absorbance on a more qualitative level using your own eyes as the detector.  This lab introduces you to spectroscopy and extraction. The solvents used are non-toxic making them Inherently Safer and allowing us to conduct the extraction using Safer Solvents. Additionally, the extracted β-carotene comes from Renewable Feedstocks.

 

See the attached documents for the lab activity and activity with teacher’s notes.

 

Take a picture of yourself and peers conducting this experiment during NCW and tweet @ACSGCI using #greenchemistry and #NationalChemistryWeek!
