Over the past five years or so there has been growing public awareness and increasing attention being paid to how society might move towards a Circular Economy. Organizations like the Ellen MacArthur Foundation have been at the center of this movement and have been advocating in a variety of areas, most notably thinking through Society’s unsustainable use of plastics and how to address what is now seen as a global blight of plastics in the oceans. If one begins to think deeply about the technical and economic issues surrounding any move towards a circular economy, it is readily apparent that there are a large number of major technical, behavioral, cultural, and economic hurdles to overcome. It is also apparent that looking at product development from a systems thinking, life cycle, and green and sustainable chemistry perspective can be very powerful, and this combination of analytical methodologies may help chemists and engineers to address many fundamental impediments to closing the loop.

 

That’s why this year’s 23rd Annual Green Chemistry and Engineering Conference/9th International Conference on Green and Sustainable Chemistry is devoted to how green chemistry and engineering are instrumental in moving towards Closing the Loop. With 42 different sessions, the Conference will be covering a wide array of topics that are relevant to Closing the Loop. There are, of course big challenges to closing the loop, and a few of these are discussed in seven different sessions that cover a variety of plastics issues (degradability, oceans, etc.), critical elements, and access to medicines. Chemists and chemical engineers know the critical part that catalysis plays in making chemistry more sustainable, so it is fitting that there are four sessions touching on biocatalysis, earth abundant metal catalysis, catalysts for CO2 conversion, and catalysis that will enable the circular economy.

 

If the world needs to move towards a circular economy society will need to educate and train chemists and engineers to address the major unmet challenges of sustainability. There are five different sessions devoted to education, two of which are covering systems thinking. Systems thinking is a pivotal, fundamental skill scientists and engineers will need since closing the loop requires one to think across multiple systems and design chemicals, synthetic routes and processes in ways that minimize adverse systemic, life cycle impacts while maximizing sustainability outcomes.

 

Speaking of processes, there are six sessions related to different aspects of chemical processing. Process intensification and batch-to-continuous flow processes, especially in the batch chemical industry, are critically important avenues to decreasing the mass and energy intensity of chemical processing. An oft-forgotten consideration in green chemistry and engineering is large volume commodity manufacturing, and this year we are delighted to devote a session to how these industries can become more sustainable. Another usually forgotten unit operation in chemical processing responsible for 10- 15% of worldwide energy use is separations. A session will be exploring alternatives to distillation for organic solvent separations and separations of small molecules from dilute aqueous solutions.

 

The nature of chemical feedstocks needs to change if we are to close the loop, so there are four sessions related to alternative feedstocks. Clearly, we have a critical and continuously expanding need to use CO2 as a feedstock. Besides CO2, there is a need to see waste not as something to be burned or buried, but something that is a feedstock for chemical processes. In addition, we need to continue our evolution towards the use of biomass as a source of carbon and see the efficiency of bio-refineries rapidly increase to be equivalent to petrochemical feedstock conversion. These sessions will continue the discussion of these important areas of technical development.

 

Two other important conference session grouping are related to entrepreneurs and product development. Entrepreneurs are usually early adopters of new technologies and are responsible for commercializing many innovations deemed too risky by larger corporations. These sessions are intended to help entrepreneurs in start-ups to more efficiently commercialize their innovations. Product challenges, on the other hand, exist in companies both large and small. There are four sessions related to product challenges in textiles and electronics, with an additional session that breaks new ground with presentations on regenerative design in products. Finally, a product showcase will once again be part of the poster session and attendees will have the opportunity to see products that are being commercialized.

 

While there are many other sessions I’ve not described, I will end with three sessions related to the use of computers for toxicity prediction, in-silico design and artificial intelligence. In one way or another, all of us will be touched by the rapid development and implementation of AI/machine learning in discovery, process design and control, and product design. I am personally very excited to see these sessions as I strongly believe that chemistry is ripe for disruption through these technologies.

 

Regardless of which sessions you attend, I hope you are able to join us for what promises to be a most interesting and exciting conference!

Unless you have been off the grid over the last three months, it is clear the era of divided government is fully formed. With Democrats taking control of the House of Representatives and the GOP holding serve in the Senate, the prospects for legislative achievement may seem remote. However, the partisan nature of our current government hides the prospects for real progress on federal support of sustainable chemistry.

 

Let’s start with the obvious: The Democrats won 40+ seats in the November 2018 elections. With this victory comes total control of the House of Representatives. The Majority sets the rules and agenda, leaving the minority party a few procedural paths to complain, but no prospect for changing legislation. In the Senate, the minority Democrats can delay, shape, and occasionally block legislation, but ultimately, Senate Majority Leader Mitch McConnell (R-KY) determines the floor agenda, meaning consensus is necessary for action. Of course, ultimately the President must sign any legislation.

 

For all the media coverage of the Green New Deal, the proposal is more idea than real legislation. From a legislative standpoint, we’ve already seen passage of a major federal lands bill, and there is strong desire to do bipartisan energy legislation, as well as possible infrastructure bills. Other energy/environment topics are likely to be small or partisan, with Democrats attempting to advance measures on climate change, renewable energy, and protecting the environment, while Senate Republicans focus on expanding drilling and mining on federal lands and cutting regulations.

 

One area that is showing promise, is possible bipartisan legislation to expand the federal role in promoting green and sustainable chemistry. Congressional activity in this realm is not new: Twice Congress has authorized, but not funded, a sustainable chemistry program at the National Science Foundation (NSF). A decade ago, the House of Representatives twice passed legislation creating a broad interagency federal program to support development of green chemistry at NSF, the Department of Energy, National Institute of Standards and Technology, and the Environmental Protection Agency.

 

What has changed is Senator Chris Coons (D-DE) and Senator Susan Collins (R-ME) are leading an effort in the Senate to invigorate green and sustainable chemistry in the federal government. In 2018, they introduced the Sustainable Chemistry Research and Development Act. The legislation seeks to create an interagency task force to coordinate research across federal agencies, while also promoting partnerships with the private sector, and increasing reporting to Congress to understand government efforts in this field. Coons and Collins will reintroduce the legislation in 2019, and the prospects are legislation in the House are good, where several members are discussing cosponsoring the bill.

 

With Democrats in control of the House, and a GOP Senate, we are likely in for plenty of tired shouting matches on cable news, but in the realm of green and sustainable chemistry, there is a real possibility of agreement. If you believe in the exciting research green chemistry can bring to the chemical enterprise, a Democrat Congress/Republican Senate might just be the catalyst for which we have been looking.

The ACS GCI Pharmaceutical Roundtable convened on October 9-10, 2018 at the Pfizer site in Groton, Connecticut for their fall meeting. With the vast majority of the 22 member companies represented in person, the meeting provided an opportunity for the various project teams to present updates on the numerous current initiatives on-going throughout the Roundtable ranging from the various grant programs, global outreach, green chemistry enabling tools as well as opportunities arising from engagement in new emerging pharma modalities.

 

The meeting’s opening remarks were delivered by Pfizer's Steve Brooks, Senior Vice President of EH&S, who has been the senior sponsor for the Pfizer Green Chemistry program for over 10 years. Steve spoke regarding the importance of linking product sustainability to green chemistry and how the program as a whole is embedded within the company’s business imperatives and cultural initiatives. From the Roundtable's perspective, the potential impacts to be realized from the relatively recent ignition grants were highlighted by a presentation within the meeting from Professor Jeff Byers, Boston College, who spoke on the emergence of iron as a viable alternative to the precious metal palladium in mediating carbon-carbon bond formations, which are prevalent throughout the industry. In addition, Greg Whiteker, Fellow at Dow AgroSciences, provided an overview of the chemistry within their crop protection portfolio highlighting the synergy between agrochemicals and pharma in the application of green chemistry principles in process development. Finally, the emergence of continuous manufacturing within the pharmaceutical industry and the paradigm shift this represents in terms of strategy and logistics was stressed by Lynne Handanyan, Vice President of Medicinal Sciences at Pfizer, who presented on the rapidly progressing initiatives on-going within Pfizer to address this challenge.

Coupled to the meeting on October 11, 2018 the ACS GCI Pharmaceutical Roundtable Flow Chemistry Team organized a standalone symposium focused on “Recent Innovations in Flow Chemistry and Continuous Manufacturing.” Despite both the specialty chemical and pharmaceutical industry’s traditional reliance on batch processes, there is a growing realization that continuous processes provide advantages from both a logistical and sustainability perspective. This meeting sought to bring together leading practitioners in flow chemistry from both academia and industry to speak on the latest emerging developments aimed at overcoming the technical hurdles involved in translating a process from batch to a continuous mode.

 

Scientists from both industry and local academic institutes filled the Pfizer lecture hall, and after a brief welcome from Juan Colberg and Paul Richardson from the Pfizer organizing committee, Lynne Handanyan gave the introductory remarks, stressing both the importance of realization that the implementation of flow-based processes can have significant advantages, as well as reiterating Pfizer’s commitment to this synthesis technology throughout chemical development.

 

These remarks lead into the first talk from Professor Richard Bourne, University of Leeds, UK, on the use of “Self-Optimizing Reactors for Rapid Sustainable Process Development,” which emphasized the need for an interdisciplinary approach at the interface between chemistry and chemical engineering in order to develop automated flow systems combining online analysis, feedback control as well as evolutionary algorithms to provide both process and understanding and enable optimization. Drawing on a series of examples including the optimization of the final step of the EGFR inhibitor, AZD9291, Richard was able to demonstrate how a flow system was able to automatically work through a series of experiments in a manner resembling a DoE to reach the optimal process conditions whilst evading the pitfall of identifying local maxima.

 

The second speaker was Kevin Cole, Principal Research Scientist at Lilly, who presented on the “Environmental Aspects of Lilly’s Small Volume Continuous Manufacturing Platform,” highlighting two compounds—prexasertib and merestinib—from the company’s oncology portfolio. In the two cases studies, Kevin emphasized the advantages of employing a continuous-based approach specifically in terms of running hazardous chemistries, minimizing worker exposure to high potency compounds, energy savings and a reduced operating footprint. He also stressed the further challenges that need to be addressed such as avoiding the use of strong solvents (e.g., DMSO, etc.) as well as driving towards a reduced Process Mass Intensity (PMI).

 

Matt Bio, CEO and President of Snapdragon, gave a presentation entitled “One Process from Milligrams to Kilograms: Efficient Drug Substance Development Enabled by Continuous Manufacturing Technology.” A recurring theme throughout Matt’s presentation was the development of a customized reaction engineering approach in order to optimize the chemistry at the development stage, and thus allow seamless and efficient scale-up to be realized using scaled equipment. This was highlighted by solutions presented to chemistries that are often challenging to run in batch, such as photoredox and gas-liquid reactions—specifically here ozonolysis.

 

Directly prior to the lunch break, Professor Frank Gupton, Virginia Commonwealth University, spoke regarding “Increasing Access to Global Healthcare through Process Intensification: The Medicines for All Initiative.” This initiative takes a multifaceted approach to ensuring global access to life-saving medications considering the complete life cycle through synthetic-route design, environmental impact, as well as implementation of a commercial supply network. Within the synthesis portion, novel manufacturing platforms such as flow play a critical role, and Frank presented case studies including the development of a newer higher-yielding synthesis of the antiviral (HIV) nevirapine, work for which he (and Prof. Tyler McQuade) were recently recognized for with the 2018 Green Chemistry Challenge Academic Award.

Joel Hawkins, Senior Research Fellow at Pfizer, initiated the afternoon session proceedings with an overview on his teams work on “Flow Chemistry for Greener and More Efficient API Synthesis”. Highlights of the presentation included application of a trickle-bed meso-flow reactor allowing the selective hydrogenation of a series of pyridine-based substrates as well as the application of flow chemistry to the synthesis of a fluorocyclobutane-containing H3 antagonist. Seongho (Ryan) Oh, Vice President of R&D at Biotek, then provided an overview of the continuous processing based technology implemented within SK Biotek. The talk was split into three sections looking at continuous organic synthesis, continuous homogeneous and heterogeneous catalytic reactions and integrated continuous synthesis. As well as several highly impactful examples of running hazardous chemistries in flow, the presentation also demonstrated the advantages of running cryogenic chemistry under this paradigm with several lithiation-based chemistries developed and subsequently executed on metric-ton scale.

 

University of British Columbia's Professor Jason Hein’s talk, entitled “Continuous Preferential Crystallization as a Simple, Scalable Technique to Access Chiral Targets,” demonstrated how the manipulation of parallel solid-liquid equilibria in continuous flow could be utilized to resolve a mixture of enantiomers. This methodology was successfully applied to pharmaceuticals such as naproxen and omeprazole, and then extended to non-natural amino-acids such as 2-fluorophenylglycine. Jason then described how robotics and a feedback loop had been applied to this technology to ensure a continuous “self-correcting” system, and spoke about his laboratories further endeavors with the implementation of automation.

 

The final speaker of the day was Richard Robinson, Senior Investigator at Novartis, who spoke regarding “Batch to Flow Transfer via a Self-Optimizing Reaction Platform.” Richard initially described a slug-flow-based approach to reaction screening utilizing an oscillating-reactor, which could be easily adapted to evaluated photoredox-based transformation. Results from the screen could be coupled with a self-optimizing algorithm with the optimization and subsequent scale-up of an Ir/Ni-mediated decarboxylative arylation demonstrated in a commercial Vapourtec flow reactor. Several other examples were presented including a case study involving the successful manipulation of suspensions in flow with future needs in this area identified specifically surrounding the development of more complex algorithms capable of optimizing around non-continuous variables.

 

The symposium as a whole was a great success and served to highlight rapid advances in flow and continuous manufacturing from across both academia and industry. There is no doubt that this is an exciting time to be involved with the evolution of this technology, and the work presented emphasized that although there are still challenges ahead, these will be met with creative solutions from those involved in this field.

ACSI-Dehli-student-group.jpgThe ACS International Student Chapter at the University of Delhi in India has been actively involved in organizing several national and international conferences and workshops. Spreading the importance of and knowledge about green chemistry is the major and continued focus of the group. The activities and events planned by the chapter are aimed at bringing information to others about green chemistry and encouraging those in the academic world to adopt it into their lectures, laboratories and research. It is the sincere efforts of our Student Chapter Faculty Advisor & Coordinator of Green Chemistry Network Centre, University of Delhi, Prof. R. K. Sharma, who plays an indispensable role in popularizing green chemistry by organizing numerous chapter activities.

 

Recently, the chapter has organized an International Conference on “Advancing Green Chemistry: Building a Sustainable Tomorrow” that aimed at initiating conversations on deep environmental issues by creating an interdisciplinary platform to share new information, advances and outlook in green chemistry to answer current and future prospects. The conference covered the crucial problems of our planet--the speakers in the conference presented the latest green initiatives in energy, environment and health based on their own experiences in either industry or academia to address the challenges and opportunities in green chemistry.

They provided strategies for designing, adapting and incorporating new green techniques in industries as well as in academia. The Conference promoted and developed the chemical sciences for the benefit of society and cost-effective solutions that can be implemented by local leaders and replicated in other areas of the world facing similar circumstances. Dr. David Constable, Science Director, ACS Green Chemistry Institute, participated and shared his views in the conference.

 

The chapter also believes that the concepts, strategies and practices of green chemistry can be best implemented by administering green chemistry courses in the curriculum. For this, a special workshop was organized by the chapter in which a large number of students and teachers from various colleges of University of Delhi participated with great enthusiasm. Through their interaction regarding teaching courses in Green Chemistry namely a skill enhancement course entitled “Green Methods in Chemistry” and also a discipline selective elective in Green Chemistry”, participants learnt about the new developments in this area and steps to further improve the way we perform our experiments so as to make chemistry labs safer and healthy for students. These improvements will spark creative seeds in the minds of young students and thus they will be motivated to opt for chemistry as a discipline.

 

Considering the importance of hands-on laboratory science, the chapter also organized an event in which the undergraduate students were given an opportunity to perform various green chemistry experiments. The event provided a platform to the students to broaden their outlook towards the recent trends in the field.

 

sharma.jpgThe chapter also supports its members to get involved with numerous scientific societies across the world and to share diverse ideas with students, teachers and researchers. We are highly indebted to ACS as it always provides numerous meaningful opportunities for the development of young chemical scientists through its scientific or career themed outreach programs such as ACS National Meetings. We were extremely fortunate to be awarded with 255th ACS National Meeting Travel Grant with which our faculty advisor Prof. R. K. Sharma, along with the Secretary of the chapter, Sriparna Dutta, gained cross-cultural experiences and learnt more about the society and its resources by attending the meeting at New Orleans. Prof. Sharma also delivered his talk on “Fabrication of magnetically retrievable metal nanocatalysts for organic transformations,” which was highly appreciated by all the attendees.

 

award.jpgOur chapter also keeps on participating in various international conferences being organized by the American Chemical Society. Prof. Sharma and his research scholar Dr. Manavi Yadav (Former President of ACS Student Chapter) participated in 21st Annual Green Chemistry & Engineering Conference on June 15, 2017 at Reston, VA, USA. The GC&E conference has been long recognized as world's best and one of the most important meetings in the field of green chemistry and engineering. It routinely attracts the world’s top scientific researchers, along with government and industry leaders. Our research work was recognized by American Chemical Society in the form of first prize in best student poster at the conference.

 

Our chapter is making a lot of efforts to motivate the younger generation towards sustainable development and green chemistry. In this direction, we are also planning to organize a conference for young researchers and students in collaboration with ACS Green Chemistry Institute. Prof. Sharma believes that the bright future of green chemistry lies in the hands of budding researchers. He often says, “the day when every individual become vigilant to incorporate green chemistry in daily practices, my dream of making the planet a better place to live in will come true!”.

It is hard to believe we are already approaching the end of February! Each year seems to pass more quickly than the last one and 2019 is shaping up to be a busy year for chemistry, thanks to the International Year of the Periodic Table of Chemical Elements (IYPT). The United Nations declared 2019 as the IYPT to commemorate the 150th anniversary of Dmitri Mendeleev’s discovery. ACS’ IYPT initiatives are designed to engage our members in sharing their passion for chemistry in order to enhance public appreciation for chemistry's role in everyday life and increase awareness of chemistry's contributions to a sustainable planet. ACS GCI will leverage IYPT to raise awareness about endangered elements and the role that green chemistry and engineering can play in preserving these precious and finite resources.

 

As always, a major activity of the ACS Green Chemistry Institute® is the Annual Green Chemistry & Engineering Conference, which will be held in conjunction with the 9th International Conference on Green and Sustainable Chemistry. We received over 500 abstracts for this joint meeting, which will be held in Reston, Virginia from June 11-13. More than 40 technical sessions, networking receptions, poster presentations, and exciting keynotes will focus on this year’s conference theme of “Closing the Loop” of the chemical life cycle. We are thrilled to be joined by keynote speakers Udit Batra, CEO of MilliporeSigma; Lee Cronin, Regis Professor at the University of Glasgow; and Dana Kralisch, CTO of JeNACell GmbH. Learn more about this year’s conference at www.gcande.org.

 

On the education front, we are excited that the Journal of Chemical Education has announced a call for papers for a special issue on “Reimagining Chemistry Education: Systems Thinking and Green and Sustainable Chemistry.” ACS GCI played a key leadership role in assembling the guest editorial team for this special issue as well as guiding the development of the call for papers, which is accessible at https://pubs.acs.org/doi/full/10.1021/acs.jchemed.8b00764. Submissions are being accepted through April 1.

 

The ACS GCI industry roundtables play a key role in advancing the implementation of green and sustainable chemistry and engineering across the pharmaceutical, chemical manufacturers, formulators, hydraulic fracturing, and biochemical technology sectors. In particular, the Pharmaceutical Roundtable grew to 28 member companies and awarded $175,000 in research grants in 2018. The Chemical Manufacturers Roundtable is finalizing its report on Alternative Separations, a project funded by the National Institute of Standards and Technology. And the Hydraulic Fracturing Roundtable met last month and has initiated a project to explore enzymatic degradation of biofilms to reduce biocide use in the hydraulic fracturing.

 

ACS GCI continues to identify ways in which green chemistry can address the UN Sustainable Development Goals (SDGs). We organized a symposium on this topic at last week’s meeting of the American Association for the Advancement of Science, which elicited a lively discussion at the intersection of green chemistry, systems thinking, education, and policy. We will focus increased attention throughout the year on ways in which ACS can contribute to the SDGs, and we welcome your input. Please feel free to contact us with your ideas and suggestions at gci@acs.org. Thank you!

The Undergraduate Student Chapter Awards Ceremony at the ACS National Meeting in Orlando is coming soon, and this year we will be congratulating 76 student chapters who have won the Green Chemistry Award! Included in this number are four International Chapters –newly eligible this year—who won: Federal University of Rio de Janeiro (Brazil), Universidad Icesi (Colombia), Universidad de Costa Rica, and the University of Delhi (India).

 

The Green Chemistry Award signifies that student chapters have successfully done at least three activities in the school year focused on green chemistry.

 

One of the most important aspects of this award is demonstrating that the chapter understands the difference between general sustainability, environmental chemistry, and green chemistry—three related but different concepts.

As the Georgia State University Student Chapter put it:

“In previous years, it was thought that green chemistry had the same definition as sustainability, and that green chemistry was just about reusing, recycling, and cleaning up. This year, it was learned that green chemistry is being conscious as chemists about the environmental impacts at every step of your work. Green chemistry calls for designing ways to prevent waste down to the molecular level. It is not using chemistry to clean up water and air pollution or waste that was already in an environment. It is about implementing greener methods and technology that does not create waste in the first place to be cleaned up.”

One way to get a firm start on the right track is by attending a relevant ACS webinar or Program-in-a-Box and using the green chemistry tie-in activities that ACS GCI has prepared. The upcoming February 26th Program-in-a-Box on the Periodic Table will include a green chemistry activity.@ Past events can also be used, including a dive into bioplastics and EPA’s Safer Choice Program.

 

Of course, there is no shortage of ideas for how chapters can go green—just look as a few examples from this year’s winners!

 

Students from Heidelberg University held a green lab contest were students wrote essays evaluating a reaction of their choice and how it could become a greener reaction using green chemistry design principles. The papers were judged by faculty with winning ideas to be considered for incorporation into labs next year.

 

Northeastern University students hosted a number of excellent speakers covering topics such as the importance of design for degradability, using flow chemistry to reduce waste and improve safety, and the challenges of degradability in modern polymers and how green chemistry could approach this problem.

 

Students at the University of Alabama at Birmingham created two trivia games—a green chemistry Jeopardy and Family Feud. Green chemistry trivia topics were divided into the areas of medicine, diseases, public policy, the environment, famous chemists and famous sites of ethical green chemistry issues.

 

The University of Detroit Mercy students taught a group of third graders about green chemistry using M&M’s to demonstrate atom economy. The importance of reducing waste was brought home when all the green M&M’s had to go in the “waste”—a beaker filled with water—and could not be eaten.

 

Wilkes University students made biodiesel and glycerin from waste oil produced by the campus cafeteria. The biodiesel was offered to the Wilke’s engineering department and the glycerin was later used to make soap in a general chemistry lab. The students learned about preventing pollution, producing biodegradable products and creating an energy efficient product.

 

If you are coming to Orlando, make sure to attend the CHED symposia Green Chemistry Student Chapters: Stories of Success to hear from a selection of ACS Student Chapters on their green chemistry initiatives. Co-organized by ACS GCI, the session will be held on Monday, April 1, 2019 from 8:30 a.m. to noon in the Convention Center, Room W311C.

 

The ACS Student Chapter Awards Ceremony will take place on Sunday, March 31, 2019 at 7 p.m. in the Convention Center, Valencia Ballroom A.

Attending and presenting at a scientific conference is an important milestone and professional development opportunity for young researchers. To enable this experience for more early-career scientists, the ACS Green Chemistry Institute® (ACS GCI) administers three annual awards for students and postdoctoral scholars pursuing research incorporating green chemistry and engineering design principles. In total over the years, 95 scholars have benefited from these awards, representing a growing pool of young scientists and engineers who will be at the forefront of research as we tackle our planet’s most pressing sustainability challenges in years to come.

 

This year, seven awardees were selected from an impressive pool of applicants. The winners hail from seven different U.S. institutions: The University of South Carolina, Yale University, George Washington University, North Carolina State University, Gordon College, Florida Gulf Coast University and the University of Louisville/duPont Manual High School.

 

Thank you to our dedicated judging panels for volunteering their time to review the ever-growing number of applications and Congratulations to these outstanding researchers!

This technology eliminates chlorine in the production of polyvinyl chloride (used to make PVC pipes, etc.), along with a chlorine-free method of producing propylene oxide, commonly used to make lightweight polyurethane foams and a variety of other valuable products. The eShuttle™ process reduces the power consumption of manufacturing propylene oxide by 60% compared to the conventional process, saving 10 million tonnes of CO2 per year. The new process also eliminates asbestos and mercury and removes the potential for the creation of chlorination byproducts associated with the current chlor-alkali process.

8th IUPAC International Conference on Green Chemistry

 

I had the pleasure of participating in the 8th IUPAC International Conference on Green Chemistry in Bangkok, Thailand on September 9-14.  Professor Supawan Tantayanon organized the conference in collaboration with Professor Pietro Tundo, chair of IUPAC’s Interdivisional Committee on Green Chemistry for Sustainable Development. The conference attracted an international audience that shared research in tracks on green chemicals, polymers, and materials; green synthesis, manufacturing, and engineering processes; green fossil energy, biomass, and future fuels; and green chemistry education.  This is the first time this conference was held in Asia and it proved a wonderful venue for highlighting advances in and establishing collaborations on green chemistry research and education.

The 22nd Annual Green Chemistry & Engineering Conference in Portland, Oregon in June 2018 featured a new interactive workshop concept. Herein, we summarize key outcomes of the workshop titled Metrics - Advances and Limitations in Determining the Greenness of Drug Manufacturing, which was chaired by Frank Roschangar from Boehringer Ingelheim Pharmaceuticals, and featured five expert speakers from the ACS Green Chemistry Institute (GCI) and industry.  Each speaker presented their metrics-related topic in just 10 minutes, followed by the deployment of various idea-generating tools, namely SWOT (Strengths, Weaknesses, Opportunities, Threats), PPCO (Pluses, Potentials, Concerns, Overcome concerns; credit: Lisa Bodell, futurethink) and Assumption Reversal (credit: Lisa Bodell, futurethink), to stimulate interactive 15 minute discussions and suggestions for improvements on each topic.

David Constable from ACS GCI presented Green Chemistry Metrics – Yes, you need more than one!  He emphasized that researchers ought to apply a system-wide view of chemistry and adopt a multivariate metrics approach to each assessment so that the environmental impact is optimized across the lifecycle of the product. From the subsequent discussion emerged the idea of reaching broad agreement on strategies for using differentiated metrics to effectively drive desired improvements.

 

Austin Smith from Amgen introduced Inspiring process innovation via an improved green manufacturing metric: iGAL, a new benchmark for manufacturing process waste at each stage of the pipeline. In the interactive session, opportunities were identified such as collecting more data and applying the concept to the pharmaceutical supply chain.

 

Eric Simmons from Bristol-Myers Squibb offered his perspective on Non-mass based metrics: Assessing environmental, health and safety impacts of chemical processes that led to the development of a comprehensive Process Greenness Scorecard for small-molecule APIs.  One opportunity that came out of the discussion was how to build industry consensus around the weightings of the individual metrics.

 

Michael Kopach from Lilly discussed Metrics for medium-sized drugs: Polypeptides and Oligonucleotides and disclosed that green chemistry has found little application in the preparation of these medium-sized molecules.  The audience found this field to have significant potential for adopting or developing adequate metrics to stimulate green innovation.

 

Sandra Robaire from Merck elaborated on the Streamlined PMI-LCA (Process Mass Intensity – Life Cycle Assessment) Tool for Small Molecules, which was recently streamlined by the ACS GCI Pharmaceutical Roundtable as a more comprehensive tool when compared to mass-based metrics.  The ensuing interactive discussion revealed that collecting full LCA data on common reagents and crafting case studies from multiple companies may enhance the value and utilization of the tool. Overall, the sessions were highly participative and well received as such.  The output of each session was summarized by the chair and sent to the speakers for their consideration.  We are hopeful that several suggestions and ideas will have been followed up and results will be presented at the metrics workshop at the June 2019 Green Chemistry & Engineering conference in Reston, Virginia.

Last week I heard a word that I had never heard before. It was a term explaining a phenomenon that has skyrocketed in the last years. The word was uberization.

 

At the time, I could already guess the meaning behind the expression seeing as I knew about the company from which the term is derived, but when I got home I still wanted to look it up because it really rang true to a project that we are working on in my organization.

 

An explanation I found on the internet stated that the term refers to “the utilization of computing platforms in order to facilitate peer-to-peer transactions between clients and providers of a service, often bypassing the role of centrally planned corporations”.

 

Wait, had I accidentally clicked on something that sent me straight to the project description of Marketplace?

 

Let me back up a little bit.

 

I work for ChemSec, a non-profit organization working towards a future free from hazardous chemicals. We work closely with decision makers and companies, advocating progressive legislation and sustainable chemicals management.

 

Working closely with corporate chemicals management has made us aware of a problem that many companies have when it comes to phasing out hazardous chemicals in their products and supply chains. They do not know where to find safer alternatives, and oftentimes they do not even know what they are supposed to look for since information regarding these alternatives is not readily available to them.

 

At the same time, we saw all these small start-ups popping up with innovative technical processes and alternative materials that would be game-changers in the industry if they only had the opportunity to market them. We also knew about large chemical producers that already had safer alternatives in their portfolios but for various reasons did not actively promote them.

 

The solution was quite obvious to us. We needed to connect supply with demand.

 

“Let’s uberize it!”, someone… did not say in a meeting. But someone might as well have, because that is exactly what we are trying to do. We want to enable potential customers to be put into direct contact with potential providers of safer chemical alternatives, eliminating the role of the middle man.

 

So, we created Marketplace.

 

 

 

Marketplace is a meeting point where buyers and sellers of safer chemical alternatives can interact. The website is meant to be a hub, similar to eBay, Craigslist or… well, Uber. If you are looking for an alternative you post a request, if you have a safe alternative you advertise it. If you are unsure you can just scroll through all the ads, using filters for chemical functions, industry or a specific hazardous chemical that you are looking to substitute.

 

A year into its development cycle, a wide range of stakeholders already recognize the potential in Marketplace. Large retailer brands, big chemical producers and small start-ups are posting more and more advertisements and requests, and European legislators and green chemistry leaders in the U.S. use Marketplace to stay updated on the latest alternatives and industry trends.

 

Hopefully, this uberization of safer chemical alternatives will lead to a much swifter phaseout of toxic chemicals in products and supply chains, while at the same time promoting the production of safer chemical alternatives instead of the hazardous ones.

 

If it has worked for hospitality, transportation and random consumer goods, then why shouldn’t it work for chemicals as well?

Get ready to celebrate the periodic table! The U.N. has named 2019 the International Year of the Periodic Table (IYPT) in celebration of the 150th anniversary of the publication of Mendeleev’s groundbreaking Periodic Table of Chemical Elements. The International Union of Pure and Applied Chemistry (IUPAC) is coordinating worldwide and will be listing events on their IYPT site. The American Chemical Society also has a portal dedicated to all things #IYPT2019 from ACS including educational resources, events, contests and engagement campaigns.

 

The ACS Green Chemistry Institute is planning to help celebrate by continuing to raise awareness about the Endangered Elements and ways that we can improve elemental sustainability. We are also hoping to have IYPT programming at the 2019 GC&E/GSC Conference.

 

The ACS Committee on International Activities is sponsoring the IYPT Challenge Grant program. Grant applications are peer-reviewed, competitive and designed to assist ACS Technical Divisions, Local Sections, International Chapters and Committees with planning and efforts to develop projects, events, and resources to contribute to the scientific success of IYPT. Grants will be awarded for amounts between $1,000 and $2,000 USD. Grant applications will be accepted until September 15, 2018, at 5:00 pm EDT.

 

What are you going to do for #IYPT2019?

One of the new elements of the GC&E Conference this year was a morning dedicated to Interactive Discussions—a different session format aimed to engage participants in discussions and actively explore new approaches and tools. Feedback from participants was positive and these sessions offered a welcome change and a great opportunity to meet and talk to new people.

 

We will be recapping the session in two parts. Part II will be published in the August issue of The Nexus.

 

Building Green Businesses

The Building Green Businesses interactive session engaged participants in exploring strategies to translate green chemistry technologies into commercial applications. Participants developed a business model canvas addressing a green chemistry challenge in the textile sector. This approach required attendees to work in teams to consider a number of factors, including customer segments, value proposition, and key partners, in developing business models. Organizer Marty Mulvihill of Safer Made shared information on funding sources, talking with investors, and building a start-up team.

Implementation Strategies for Green Chemistry in Products – What are the Barriers, Opportunities, and Key Elements for Making Sustainable Consumer Goods?

 

In this session led by John Frazier, Bob Buck and Scott Echols, participants were lead through a series of thought-provoking questions and engaged in conversations to identify barriers to implementing green chemistry and then brainstorm potential solutions. The top five barriers identified were 1) long development/scale time, 2) regulatory requirements, 3) cost/investment, 4) clear communication with supply chain, and 5) economy of scale vs. existing chemicals.

High-level routes to overcome these barriers included:

  • Predictive modeling to identify greener alternatives
  • Communicate clear expectations across regulators, brands, suppliers
  • Seek “Co-opitition” Opportunities (competitors collaborating)
  • Educate to create demand
  • Reduce risk through investment insurance model
  • Develop greener purchasing systems
  • Enable fail-fast R&D
  • Multi-disciplinary approach to green chemistry needs
  • Recognize green chemistry as innovation

 

Minimizing Ecotoxicity and Persistence in Chemicals and Materials

Is it possible to develop a “safe” diazo dye? The Minimizing Ecotoxicity interactive session allowed participants to examine the acute and chronic ecotoxicity of chemical and material safety by using predictive models.  During the session, the attendees were asked to select three candidate compounds to propose a safer aromatic amine alternative based on ecotoxicity and biodegradation data. By studying a list of Primary Aromatic Amines (PAAs), the acute and chronic ecotoxicity data associated with them, in addition to predicted data on biodegradation, the attendees were able to create a list and report out their safer selection. After participants identified their “safer” compounds, they learned about the different methods of ecotoxicity data collection and how it’s used in an integrated approach to identify chemicals safer to other species.

The Hancock Award provides national recognition and honor for outstanding student contributions to furthering the goals of green chemistry through research and/or studies.

 

Roberts' research is directed towards improving the production of biofuels by scaling catalytic nanoparticle fabrication. She is investigating earth-abundant catalysts composed of Ni and Ni2P.  Her research is also focused on transitioning and scaling the batch manufacturing of these nanoscale catalysts to a continuous flow droplet microreactor using an ionic liquid solvent in place of volatile organic solvents.

 

The Hancock Award is sponsored by the ACS Division of Environmental Chemistry and the National Institute of Standards & Technology.

My sincere thanks to all who attended and helped organize last month’s Green Chemistry & Engineering Conference in Portland, Oregon—what a fantastic meeting!  A total of 580 attendees shared research results, engaged in interactive discussions, and visited the poster session, exhibitors, and product showcase.  The keynote speakers – Joe DeSimone, Don Sadoway, and Julie Zimmerman – were exceptional, and the high-energy networking events provided attendees with opportunities to establish new collaborations across sectors.

 

I would like to extend a special thanks to our conference co-chairs, Julie Haack and Richard Blackburn, for organizing such a dynamic conference. Their vision in retaining the scientific core of the conference while introducing new features, such as the interactive sessions and product showcase, was key to the success of the conference. The incredible support of my ACS Green Chemistry Institute® colleagues – Christiana Briddell, Ashley Choi, David Constable, Jane Day, Matt Deinhardt, Dawn Holt, Jenny MacKellar, Isamir Martinez, and Stephanie Wahl – was essential in delivering an outstanding meeting experience. The conference also afforded us the opportunity to recognize Kent Voorhees for his dedicated service to ACS GCI during his 11 years on the Governing Board, including five years as Chair.

Planning for the 2019 joint 23rd Annual Green Chemistry & Engineering Conference and 9th International Green and Sustainable Chemistry Conference is well underway. The conference will be held in Reston, Virginia from June 11-13, 2019 under the leadership of conference co-chairs Joan Brennecke and Philip Jessop. The call for symposia is open through September 10 and I encourage you to submit your ideas. Submissions are welcome in all areas of green chemistry and engineering, particularly those that address the conference theme of “closing the loop” of the chemical life cycle.

 

While much of ACS GCI’s attention has been lately focused on the conference, work continues on other fronts, as evidenced by two recent publications. Jim Hutchison and Tom Holme, who are deeply involved in developing the Green Chemistry Education Roadmap, published an editorial in the April issue of the Journal of Chemical Education on “A Central Learning Outcome for the Central Science”.  The Central Learning Outcome articulated in this article is that “Chemicals have benefits and hazards, and these must be considered together.” Tony Noce, ACS GCI Advisory Board member and Chair of the ACS Committee on Environmental Improvement, authored a May 27 comment in Chemical & Engineering News that outlined how chemistry can help meet the UN Sustainable Development Goals.  He highlights chemistry’s essential role in meeting these ambitious goals.

 

Finally, I hope to see many of you at the ACS National Meeting in Boston next month. Symposia on green chemistry are featured in many of the technical divisions, including catalysis, chemical education, environmental, and organic.  Please stop by the GCI booth (#1418) in the exhibit hall – we look forward to welcoming you!
