Bibhu Prasad Sahu’s life is dedicated to transforming rice husk waste into eco-friendly solutions, redefining waste management and inspiring a greener world.


Interviewer: Can you tell us about your journey from a para-teacher to an agripreneur? 

Bibhu Prasad Sahu: Certainly. About two decades ago, while most of my fellow villagers were engaged in paddy cultivation, I chose a different path. I ventured into rice milling, starting Haripriya Agro Industries in Paiksadhel village. The dream of owning a venture was compelling, and I followed my passion, stepping away from the conventional route.


Q: What inspired you to explore the potential of rice husk waste? 

A: The turning point was in 2016 when my rice mill started generating significant amounts of rice husk ash. Instead of disposing of it, I saw an opportunity to turn this waste into something valuable. It was a challenge that sparked my determination to find an innovative solution.


Q: Could you elaborate on how you transformed rice husk ash into thermal insulators? 

A: Absolutely. My team and I crafted ball-shaped thermal insulators from rice husk ash. These insulators found a practical application in steel production, primarily as thermal insulators in steel ladles and tundishes. The unique properties of rice husk ash, such as low thermal conductivity and a high melting point, make it ideal for this purpose.


Q: Did you face any obstacles during this journey of innovation? 

A: Indeed, challenges were part of the journey. In 2017, some locals raised concerns about the disposal of rice husk ash, citing air pollution concerns. This setback turned out to be a blessing in disguise. It forced me to think of alternative ways to utilize the ash, leading me to explore the creation of rice husk ash pellets.

Q: How did you overcome these obstacles and develop the pellet-making process? 

A: Overcoming these obstacles required collaboration and creative thinking. Drawing on the knowledge of local youths from the potters’ community and the expertise of engineers, we designed machines that could shape rice husk ash into pellets. This collaboration between traditional knowledge and modern innovation was the key to our success.


Q: Can you share the impact of your innovation on the steel industry? 

A: The impact was significant. The rice husk ash pellets we developed were not only eco-friendly but also cost-effective. They found applications in steel industries as thermal insulators, addressing the issues of non-uniform solidification during the casting process. The pellets burned uniformly and did not emit smoke, making them an ideal choice for the industry.


Q: How did you expand your reach beyond your local community? 

A: Recognition from the steel industry and various research organizations propelled our journey. We sent samples of our rice husk ash pellets to steel industries globally. The first breakthrough came when EZDK, Egypt’s first steel plant, invited us to demonstrate the use of our pellets in steel production. This opened doors to wider opportunities and recognition.


Q: What do you envision for the future of your venture? 

A: I see a future where sustainability is a cornerstone of industries worldwide. I believe that waste-to-energy solutions, like our rice husk ash pellets, can play a crucial role in creating a greener and more eco-friendly world. I aim to expand our reach to even more countries and industries, contributing to a more sustainable future.


A visionary with unwavering determination, Bibhu Prasad Sahu exemplifies the fusion of ingenuity and environmental responsibility in the pursuit of a brighter future.


Q: What advice do you have for aspiring entrepreneurs and innovators? 

A: My advice is to embrace challenges as opportunities for innovation. Don’t be afraid to think outside the box and collaborate with diverse groups of people. Traditional knowledge often holds invaluable insights that, when combined with modern expertise, can lead to groundbreaking solutions. Most importantly, never lose sight of the positive impact your innovation can have on the environment and society.


Q: What do you consider your greatest achievement in this journey? 

A: My greatest achievement is the dual impact we’ve achieved. Not only have we found a sustainable solution for rice husk waste, but we’ve also contributed to local employment. In an era of unemployment, being able to create job opportunities for the community is incredibly fulfilling. It’s a reminder that entrepreneurship isn’t just about profits; it’s about making a positive difference.


Q: How do you see your venture contributing to a more sustainable future? 

A: In a world grappling with pollution and environmental challenges, finding ways to convert waste into energy is a significant step toward sustainability. Our venture, by turning rice husk waste into valuable resources, contributes to reducing pollution, conserving energy, and creating a more eco-friendly industrial landscape. It’s a small yet significant stride in the direction of a greener future.


Bibhu Prasad Sahu’s journey from a para-teacher to a global agripreneur is a remarkable testament to innovation, determination, and sustainability. His creative approach to transforming rice husk waste into valuable thermal insulators has not only impacted the steel industry but also exemplifies the power of marrying traditional knowledge with modern innovation. As he continues to expand his venture’s reach, he leaves us with a powerful lesson: challenges can be the catalysts for positive change, and innovative thinking can shape a more sustainable world.
