Dow and Caltech's Resnick Institute Collaborate to Recognize Student Innovations in Sustainability

Caltech's 2015 SISCA Winning Projects Advance the Science of a Sustainable Route to Fixed Nitrogen for Fertilizer and Improve a Wastewater Treatment Technology for the Developing World

PASADENA, CA – December 17, 2015 – As the world is increasingly focused on reducing carbon emissions because of COP21, Caltech's Resnick Sustainability Institute has come together with The Dow Chemical Company to award a number of exceptional young scientists and engineers the Sustainable Innovation Student Challenge Award (SISCA) for outstanding student achievement in sustainability innovation. Caltech graduate students in chemistry Trevor J. Del Castillo and Niklas B. Thompson were awarded the 2015 Grand Prize for work aimed at facilitating a sustainable route to nitrogen fixation – an essential and energy-intensive process done on a massive scale to produce fertilizer. Cody Finke, a graduate student, and Justin Jasper, a postdoctoral scholar, are this year's runners up for progress in developing a wastewater treatment technology that delivers a high quality of water within the constraints of the developing world.

“The SISCA program is designed to recognize and encourage students to take an interdisciplinary approach to innovate and address critical challenges in sustainability,” said Eunice Heath, Global Director, Sustainable Products Marketing and Strategy. “Dow is proud to collaborate with Caltech and other leading universities to help foster the next generation of leaders, who will help solve global sustainability challenges by working outside their own areas of expertise.”

By focusing on advanced research in nitrogen fixation, the Grand Prize Winning team of Castillo and Thompson are creating greater understanding of how to make this reaction occur under mild conditions, taking inspiration from biological enzymes that fix nitrogen. Their work helps to lay the scientific foundation that will be needed to achieve a sustainable source of fertilizer for global food production. The team's research has led to robust improvement in the performance of an earth-abundant iron catalyst that fixes nitrogen to ammonia at low temperature and pressure. Coupled with an artificial photosynthesis device, the team envisions creating modular, affordable, onsite fertilizer production.

The runners up have enhanced a solar powered, electrochemical wastewater treatment system by incorporating a low-pressure (germicidal) UV lamp. The technology now rapidly disinfects and clarifies wastewater while removing nutrients and micronutrients, resulting in water that can be used for flushing, hand washing, as well as discharged for irrigation or ecosystem services.

According to Dr. Neil Fromer, Executive Director of the Resnick Sustainability Institute at Caltech, “These two teams have used some of the most sophisticated scientific approaches available to solve critical problems that are essential to the future of the planet.”

The Dow SISCA Award

In alignment with Dow's 2025 Sustainability Goals, the Sustainability Innovation Student Challenge Award (SISCA) program promotes forward thinking in social and environmental responsibility and acknowledges the energy, commitment and enthusiasm of the students and their university professors, sponsors and facilitators who support their sustainability innovations and efforts in continued excellence. Since its inception in 2009, the SISCA program has continued to expand and now engages students from 18 universities around the world. The spirit and power of global collaboration has sparked the development of long-lasting and impactful solutions.
