Many processes used in the manufacturing of textiles, apparel, and footwear are very chemically intensive. The ubiquity of these products combined with the large global footprint of this industry makes it a compelling area to highlight opportunities for systems thinking and designing for sustainable use. This session is designed to showcase new chemical technologies and strategies for reducing impact during the manufacture of textiles, apparel, and footwear, as well as new processes and new ways to design products with sustainability and end of life in mind.

This session will provide a forum for innovators in both industry and academia to come together and share ideas and challenges. Suggested topics to be addressed include (but are not limited to):

Greener Wet Chemical Processing:

• New dyes or dye processing technologies that can reduce water an energy use
• Design of more sustainable dye molecules (e.g. biobased or biodegradable dyes, dyes with reduced hazards profiles, etc.)
• More environmentally friendly functional finishes (e.g. non-fluorinated water repellants, biobased wicking finishes, metal-free antimicrobial finishes, etc.)
• Safer solvents and auxiliaries
• Tools to assess chemical hazards or environmental impact

Circularity:

• Mechanical and chemical recycling technologies for post-industrial and post-consumer textile, apparel, and footwear waste
• Technologies/strategies for handling complex mixtures of materials to enable recycling
• Material and chemical considerations to design consumer products for recycling at end of life

New Materials

• Novel fiber types, especially bioderived, biodegradable, or recyclable at end of life
• Strategies for addressing microfiber pollution (e.g. novel coatings, polymer additives, etc.)
• Safer, more sustainable adhesives

The Green Chemistry Challenge Awards are now in their 26th year and continue to recognize leading green chemistry innovations. With over 1800 nominations and 128 award winners, there is a compelling case to be made that innovations benefiting from the application of green chemistry and engineering have achieved sufficient commercial success to justify implementation in all chemical processing sectors. The goals of the panel are to describe the prestigious EPA Green Chemistry Challenge Awards, co-sponsored by the American Chemical Society, and showcase award winners from the current and past years. The winners will describe the innovative technology they were recognized for, share lessons learned from participation, and describe the benefits of being recognized by the Green Chemistry Challenge Awards Program.

The purpose of proposed symposium is to promote, fill the knowledge gap, and advance the current green chemistry research and development in the energy storage device. The emphasis to move away from the traditional coal-based production and toward cleaner forms of power generation has been a consensus among all nations. According to the International Renewable Energy Agency (IRENA), the renewable power delivered is up to 25 percent in 2020. With more renewable energy being produced from solar, hydroelectricity, wind power, biomass, tidal power, and geothermal energy, researchers realized there are needs to develop capable storage technology not only to store of excessive electric energy produced, but also to smooth out energy surge and reduce power grid fluctuation. From the traditional lead acid batteries to all vanadium redox flow battery, their application is mainly in the application of emergency power supply, power plant, and electric cars.

The symposium welcomes talk and discussion to fill the knowledge and practice gap current green chemistry research and development in the energy storage device. From cobalt-free lithium-ion battery to sodium-ion battery, from the modeling to experiment design, from the materials to electrolytes, this symposium is intended to bring the computational modeling, experimental design, and manufacturer of energy storage together to provide current state of energy storage device.

Diversity, Equity, Inclusion, and Respect (DEIR) are among the core values of the American Chemical Society. Over the last several decades, we have seen dramatic evidence that scientific advancement across all specializations is enhanced by welcoming and encouraging the creativity of a diverse population of researchers, teachers, and students. This is especially true in green chemistry and engineering, since greener innovation necessarily invokes broader concerns of sustainability and stewardship of the environment on a global scale. The need for placing explicit value on DEIR in science is underlined by initiatives such as the 17 United Nations Sustainable Development Goals (SDGs) which require synergy among the diverse communities of our planet while attempting to address large-scale challenges.

This fast-paced and engaging symposium will provide educators of all levels (K-12, undergraduate, and graduate) with the opportunity to share their innovations and initiatives for highlighting issues relevant to diversity, equity, inclusion, and respect (DEIR) while incorporating green chemistry and engineering content in lecture, laboratory, and outreach. Speakers whose curricular innovations explicitly focus on the value of DEIR through the inclusion of concepts relevant to green chemistry, thinking in systems, design for sustainable use, stewardship of the environment, and/or global initiatives such as the SDGs are welcome. Other representative topics of interest include the use of renewable feedstocks, greener synthetic methods, function-based design, intended use/end-of-life considerations, and leveraging diversity among faculty collaborators or within the student population (classroom or laboratory). Contributions of these methods to improving safety or understanding toxicology would also be welcome. Preference will be given to abstracts describing initiatives directly or indirectly relevant to highlighting DEIR. The rapid-fire session format will allow presenters seven minutes (with optional use of three minutes for content or questions) to engage the audience with a snapshot of their work and prompt audience participation.

Oligonucleotides are gaining traction as a new therapeutic modality with 12 products approved for use and many more following on. However, these compounds face significant sustainability issues, the chief of which is the large amount of waste generated during manufacture (4300 kg waste per kg of drug substance produced). Several new technologies are in development to address these issues such as solution phase chemistry, P(V) chemistry, solvent recovery, enzyme catalysed synthesis and alternative purification techniques to name but a few. The aim of this session is to highlight some of the recent developments in these areas and the potential benefits they bring to oligonucleotide sustainability. We invite abstracts on the topic of improving oligonucleotide sustainability from interested parties in academia and industry.
