Tejaswini Patil: Scaling up through technology, teamwork, and consumer trust

Winning the Packaging Person of the Year award, Tejaswini Dhanaji Patil, a doctoral researcher at IIT, Roorkee, has developed biodegradable packaging materials from millets.

Q: What do you see as the biggest hurdle in adopting these sustainable, millet-based packaging solutions across the food industry, and how do you plan to overcome it?
Tejaswini Patil (TP):
The main challenge is recognition and scalability—balancing industry adoption, consumer perception, and cost. Millets are climate-resilient but underutilised; transforming them into functional packaging demands a steady raw material supply, economical processing, and compliance with food safety standards. My strategy is to work with industry entrepreneurs and farmer cooperatives to build a supply chain and to educate consumers and align millet packaging with India’s plastic-ban policies and global climate goals. My strategy blends politics, research, and public awareness to make millet-based packaging widely available, reasonably priced, and effective.

Q: Your millet-based drinking straws are a remarkable innovation. How do you envision these edible straws impacting consumer behaviour and the broader perception of sustainable packaging?
TP
: Millet-based edible straws are a behavioural push that makes sustainability noticeable, palpable, and pleasurable in day-to-day living than just a replacement for plastic. When people can eat a straw or watch it biodegrade, it turns sustainability into a personal act. On a larger scale, these straws can shift perceptions of packaging from “waste” to a meaningful part of the dining experience. They merge nutrition, culture, and climate-conscious living, making eco-friendly choices feel like an upgrade rather than a compromise.

Q: You emphasise collaboration with academics and industry to encourage the adoption of eco-friendly packaging. Can you share an example of a successful collaboration with practical applications?
TP
: A key academic collaboration was with Prof. Kirtiraj Gaikwad, whose guidance on crosslinking, mechanical strength, and water resistance transformed barnyard millet straws from a creative concept into a viable product. Working with his team of chemical engineering and food science students provided the experimental validation needed for future industry acceptance. 

Q: Your work supports various Sustainable Development Goals (SDGs). Which specific SDG does your research on millet-based packaging contribute?
TP:
Although my study supports several SDGs, SDG 12: Responsible Consumption and Production is the one it most strongly supports. Edible straws made from millet provide a safe, practical, and biodegradable substitute for single-use plastic straws, therefore addressing the urgent need to minimise their usage. At the same time, it encourages the use of underutilised climate-resilient crops like millets, supporting sustainable agricultural methods and resource-efficient production.

Q: With your research gaining both local and international recognition, how do you plan to scale up the production and achieve global impact, especially among GenZ and millennials?
TP:
Through a mix of technology and teamwork, I want to collaborate with startups and industry partners to set up pilot-scale manufacturing facilities that can reduce costs and make the films and straws profitable. I also intend to use industry-academia partnerships to modify these materials for various regional food systems. I see a great opportunity to present edible packaging as a lifestyle option for GenZ and millennials, who are very open to innovation and are very concerned about sustainability.

 

Tejaswini Patil: At a glance

One tech trick you wish to share? 

Using edible gums as natural binders and film-forming agents in conjunction with crosslinking agents like organic acids is a useful technological technique for the packaging sector. This method produces high-performance, environmentally friendly packaging free of artificial chemicals.

If you could time-travel inside a book?
I would enter the universe of George Washington Carver’s biography, Ek Hota Carver. This book, which my father gave me when I was ten years old, had a profound effect on me. It is exciting to read about Carver’s journey from being born at the end of American slavery, being an orphan at a young age, and becoming a well-known agronomist and educator.

One factory you visit that has wowed you? 
The Amul dairy plant in Gujarat — their large-scale integration of automation, quality control, and sustainability astounded me. It showed me that even eco-friendly technologies. 

One product you wish was designed better? 
The plastic cup and food container lids are one item I had seen that got me thinking about why it hasn’t been better developed. They produce a lot of plastic trash, are single-use, and cannot be recycled. Based on my research on millet-based edible packaging and biopolymers, I see a definite chance to create edible or biodegradable lids that preserve functionality while having a smaller environmental effect. 

How did you celebrate your win? 
When I won the Packaging Person Award, I immediately went to my PhD supervisor, who has played a big part in my accomplishment, to convey the news. His warm comments and support made the occasion even more wonderful, and later I celebrated with my family and close friends.
