Chemist Saurabh Chitnis Pioneers Greener Plastics Research

Research led by Saurabh Chitnis, a newly appointed Tier II Canada Research Chair in Inorganic Polymers and Materials at the University of Victoria (UVic), is set to transform the field of materials science. Chitnis aims to explore the potential of inorganic elements to create greener plastics, addressing some of the significant environmental challenges posed by conventional synthetic materials.

Uncovering the Potential of Inorganic Elements

The periodic table, a cornerstone of chemistry, contains over a hundred elements that remain largely unexplored. Chitnis highlights that while much of chemistry has focused on organic elements like carbon, oxygen, and hydrogen, there is a wealth of knowledge still to be discovered within the inorganic realm. “The other hundred-plus elements remain poorly understood, but offer incredible potential,” he notes.

The lab’s research focuses on understanding the structure and bonding of inorganic elements, seeking to integrate them into polymers and other materials to develop innovative products with enhanced properties. Chitnis explains that current synthetic materials—such as plastics and fabrics—primarily consist of carbon, which limits their performance and environmental sustainability.

Transforming Plastics with Nitrogen

One of the key projects in Chitnis’s lab involves substituting carbon with nitrogen in polymer formulations. Nitrogen is abundant, making up 78% of Earth’s atmosphere, and has the potential to create plastics that are not only more stable but also environmentally friendly. The ability to incorporate nitrogen into polymers could facilitate the development of materials that degrade more readily, thereby reducing waste and reliance on fossil fuels.

“Nitrogen-based plastics can also be fed to plants at the end of their life cycle, acting as a fertilizer as they slowly degrade, creating a circular economy,” Chitnis states.

This innovative approach could mark a significant step forward for industries seeking sustainable alternatives to traditional plastics. Chitnis’s commitment to advancing green technologies aligns with global efforts to achieve net-zero emissions.

The Importance of Fundamental Research

While Chitnis’s work has practical applications, his passion lies in the fundamental questions of inorganic chemistry. He emphasizes that the field is ripe for discovery, stating, “When you work in such a new area, it really democratizes science. Anyone can make a big discovery, because not that much is known and there’s so much waiting to be discovered.”

In addition to polymer research, Chitnis investigates new concepts in metal coordination chemistry aimed at enhancing the efficiency of chemical synthesis. His expertise spans phosphorus, nitrogen, and bismuth, the heaviest stable element, further contributing to the evolving landscape of materials science.

A Return to Roots at UVic

Chitnis began his journey at UVic in July 2025, returning to the institution where he completed his PhD in 2015. His academic career includes postdoctoral fellowships at the University of Bristol and the University of Toronto, and seven years as a professor at Dalhousie University. His notable achievements also include receiving the Alfred P. Sloan Foundation Fellowship.

Reflecting on his return, Chitnis expresses gratitude for the opportunity to collaborate with former mentors and colleagues. “UVic Chemistry is an inspiring place to be, with interdisciplinary research taking place at the highest level,” he says.

As Chitnis embarks on this promising research at UVic, his work is expected to contribute significantly to the understanding and development of materials that prioritize sustainability without compromising performance. This pioneering effort could pave the way for a new generation of plastics, fostering a more sustainable future.
