Twenty-seventh Annual Green Chemistry & Engineering Conference

Toxicology in Chemistry Curriculum: Effective Interdisciplinary Examples

Symposium Organizers: Teresa McGrath, Chief Research Officer, Healthy Building Network and Lauren Heine, Director of Science & Data Integrity, ChemFORWARD

Training in toxicology and alternatives assessment should be incorporated into chemistry and engineering programs to equip students with the tools and knowledge to positively influence future product design or chemical development. This panel will share how chemical hazards-informed design can be integrated into classroom settings to train the future workforce. This panel discussion will bring together academic leaders to highlight how curricula can be used to increase student awareness of chemical hazards data and toxicology. Speakers will also share case studies featuring tradeoffs and decisions that must be made in the process of product design.

Participants will:

  • Learn how to screen chemicals for known hazards
  • Learn from professors who have successfully integrated an interdisciplinary curriculum that considers function, hazard, performance, and life cycle impacts to generate real world solutions to contemporary product design problems
  • Test their knowledge by choosing safer alternatives for a real world chemical synthesis problem and compare their answers to students’ conclusions
  • Walk away with curriculum examples they can incorporate into their classrooms

Data-Driven Insights and Collaboration for Further Adoption of Green and Sustainable Chemistry and Engineering Practices

Symposium Organizers: Stephen DeVito, Branch Chief, Data Analysis and Dissemination Branch, Data Gathering and Analysis Division, U.S. Environmental Protection Agency; Charlie Snyder, Environmental Protection Specialist, Data Analysis and Dissemination Branch, Data Gathering and Analysis Division, U.S. Environmental Protection Agency

Many industries are implementing product design practices that minimize negative environmental, economic, and societal impacts during the production, use, and decommissioning of products. There remains, however, profound and unrealized opportunities at the local, regional, and national level to identify, develop, and adopt these practices. These opportunities to advance sustainable production and circular economy are intrinsically cross-disciplinary. This session is intended to bring together experts from government, academia, industry and nonprofit organizations who can provide insight on success stories, barriers impeding implementation, and resources and strategies to further green/sustainable chemistry and engineering practices, and sustainable design and production of products.

The organizers encourage submission of abstracts for oral presentation in any of the following areas:

  1. Examples of successful substitution in products or green chemistry implementation in sectors, particularly through the use of analytical tools or data-driven approaches;
  2. Chemical selection strategies or tools that consider a variety of sustainable design goals (e.g., sustainable plastics work) and non-technical drivers and barriers in designing from a value chain perspective;
  3. Engineering challenges and barriers to designing products for sustainability or implementing green chemistry in manufacturing;
  4. Sustainable production practices within disadvantaged communities;
  5. Methods to amplify outreach about the above.

The session will conclude with a panel discussion focused on strategies (e.g., communication/feedback mechanisms/analytical tools) developed or needed to overcome value chain barriers and strategies for ensuring sustainable practices at each production stage. Speakers will also provide recommendations for how to systematically translate knowledge from academia to business; how to expand shared knowledge base; and how best practices could be more widely incorporated globally.

Application of Chemicals, Novel Chemistries, Synthetic Pathways and Processes that Enable a Circular, More Sustainable Economy

Symposium Organizers: Samy Ponnusamy, Fellow & Global Manager – Green Chemistry, MilliporeSigma and Srinivasan Ambatipati, Assistant Professor & Co-Ordinator of Chemical Engineering, McNeese State University

This session highlights the processes that are inspired by novel design strategies leading to successful application of technologies to enable a circular-sustainable economy. Case studies should illustrate how industry/academia/NGO have successfully implemented the novel design in chemistries, synthetic pathways and processes. This would enable a circular, more sustainable economy and the strategies that ultimately worked out for its end use to achieve its targeted goals. The examples should clearly describe the design and approaches taken, the challenges faced and how a solution for the challenge was achieved. Also, highlight the importance of implementing sustainability as a basic design criterion to successfully achieve a closed-loop economy.

The Role of Sustainable Thinking in New Chemical Reviews

Symposium Organizers: Richard Engler, Director of Chemistry, Bergeson & Campbell, P.C., and Ligia Duarte Botelho, Manager, Bergeson & Campbell, P.C.

A circular economy requires new thinking about what we make, what we make it from, and where it goes at the end of its useful life. An important but often overlooked aspect of new product development is an understanding of the regulatory framework and landscape that will govern the commercialization of the new product. The Toxic Substances Control Act (TSCA) regulates the manufacture, use, processing, and disposal of industrial chemicals. TSCA requires the U.S. Environmental Protection Agency (EPA) to review new chemicals and determine whether they would adversely impact human health or the environment. If EPA determines that a new chemical may pose a risk, EPA can either prohibit the use of the new chemical or require restrictions on the chemical to mitigate risks. Currently, EPA reviews and regulates new chemicals based solely on hazards, without regard to whether exposures are reasonably foreseen. EPA also does not consider sustainability benefits that may accrue by the introduction of a new chemical.

This symposium will be a panel discussion that explores the “new chemicals bias,” as it is called, and how it continues to pose a barrier to market acceptance of novel chemistry and sustainable thinking. The session will also include discussions on possible policy changes that could eliminate or alleviate current regulatory challenges to chemical innovation. The session will help attendees understand the regulatory landscape of TSCA implementation and how and whether EPA might change its approach to reduce barriers to circular economy innovations. It will include company representatives, EPA scientists and invited speakers from non-governmental organizations. The moderator will introduce the topic, and then each panelist will give brief introductory remarks, followed by at least 30 minutes of practical discussion among the panelists, including a question and answer session to engage with the audience.

Closing the Loop: Combining Process Analytical Technology and Flow Chemistry for Self-Optimizing Systems

Symposium Organizers: Nick Uhlig, Senior Scientist – Chemical Development, Sage Therapeutics; John M. Wasylyk, Associate Scientific Director, Bristol Meyers Squibb; Michael J. Di Maso, Senior Scientist, Process Research & Development, Merck & Co.; Mark T. Zell, Scientific Fellow, Takeda

Co-Sponsor: ACS Green Chemistry Institute Pharmaceutical Roundtable

This session will focus on novel implementations of process analytical technology (PAT) with flow chemistry, and the application of such combination systems in chemical synthesis. Particular emphasis will be given to discussing applications involving automation, self-optimizing systems, and data-rich experimentation. The use of PAT in flow to enable self-optimizing systems and greater degrees of automation represents a powerful interface between computer science, engineering, and chemistry. Benefits of incorporating PAT into flow chemical processes include reduced offline or human-interface sampling, rapid and data-rich experimentation and optimization capabilities, and real-time monitoring and control of chemical processes at lab or production scale. These benefits have great potential to facilitate process intensification and greater efficiency in chemical processing via reductions in energy and material usage, smaller instrumentation footprints, improved process safety & control, and greater flexibility in scale. This session will feature a mix of invited and submitted abstracts from a diverse array of speakers of both industrial and academic backgrounds. The target audience includes anyone who has an interest in chemical engineering, flow chemistry, or computer science.

Sustainable Chemistries and Processes to Decarbonize Aviation Fuel

Symposium Organizers: Michael R. Thorson, Senior Chemical Engineer, Pacific Northwest National Laboratories; Karthikeyan Ramasamy, Senior Chemical Engineer, Pacific Northwest National Laboratories, and;  Zia Haq, Senior Analyst, Pacific Northwest National Laboratories

Demand for liquid aviation fuels is currently 3.6 EJ and is projected to double in the next 30 years. In ground-transportation, fuel use is expected to decline due to emerging technologies such as electrification, or due to engine efficiency improvements; no such opportunities exist in aviation due to the high energy density requirement; however, aviation fuels are expected to require liquid fuels for the foreseeable future. Thus, there is a need, and large opportunity, to discover and deploy pathways for sustainable aviation fuels (SAF). Jet fuel chemical composition specifications are unique from other fuel classes (e.g., gasoline and diesel) in that fuel quality is essential, with no heteroatoms, metal contaminants, alkenes, or trace water allowed. Further, there is a strong desire to displace the aromatic content to reduce sooting behavior and increase energy density. In the nearer term there are opportunities for aviation original engine manufacturers (OEMs) and airlines to reduce emissions of CO2, soot, sulfur, contrails, and NOx while also maintaining the other mandatory operation (safety) and performance metrics of the fuel.

This session will focus on the following gaps:

  1. Development of novel sustainable chemistries and/or process that utilize lower-cost waste carbon sources
  2. Understand the chemistry interactions to address knowledge gaps in structure-function relationships, blending behavior and decision optimization (i.e., identification of chemical structures and blends that optimize emissions reductions, thermal stability and energy content, while maintaining other key fuel requirements)
  3. The value conferred from these improved fuels is undefined
  4. Reduce costs associated with producing and/or deploying SAF

Using Computers to Deliver Green Chemistry: In Silico Techniques for Designing and Developing Chemical Reactions

Symposium Organizers: Jared Piper, Director of Process Chemistry, Chemical Research and Development, Pfizer, Inc., and Jason Stevens, Computer Aided Synthesis Lead, Chemical Research, Bristol-Myers Squibb

Co-Sponsor: ACS Green Chemistry Institute Pharmaceutical Roundtable

Many tools are being created that augment human decision making and focus on large sets of data to determine trends. These techniques have the potential to minimize the number of experiments to arrive at an ideal synthesis, hypothesis, or process. In addition, models and in silico techniques can probe hypothetical situations that could prove challenging to set-up in a laboratory due to cost or safety considerations. Presentations describing recent advances in computer-assisted chemistry methods will be discussed.

Chemical Methods for the Upcycling of Waste Plastics

Symposium Organizers: James Dorman, Associate Professor, LSU, and Francisco Hung, Associate Professor, Northeastern University

Over the past few years there have been significant advances in the breakdown of plastic waste into commercial materials without cracking/pyrolysis processing. This session will focus on the upcycling of waste plastics for the production of value-added products. Specifically, this session will focus on a comparison between traditional (thermal) and non-traditional (mechanical, electrochemical, electromagnetic, etc.) routes to depolymerize waste plastics. Additionally, this session will include theoretical aspects with highlight polymer degradation mechanisms and the polymer-catalyst dynamics.
