In a significant stride towards sustainable agriculture and environmental protection, the Plasma Research Group and Water Quality Research Group at the Indian Institute of Technology (IIT) Tirupati showcased their advanced non-thermal plasma technology to Tirupati District Collector Dr. Venkateswar. The demonstration highlighted the technology’s potential to revolutionise agriculture, environmental protection, and industrial processing.
Led by Prof. Shihabudheen M. Maliyekkal and Dr. Reetesh Kumar Gangwar, the team presented scalable plasma systems designed for the decentralised production of nutrient-rich liquid fertilisers. This innovative technology converts atmospheric nitrogen into water-soluble nitrates and reactive species that are easily absorbed by crops. By offering a sustainable alternative to chemical fertilisers, it promises to reduce the agricultural sector’s reliance on imports and promote self-sufficiency.
One of the standout features of this technology is its biocidal properties. The plasma systems can neutralise pathogens, fungi, and food toxins without leaving harmful residues. This dual benefit—nutrient generation and green disinfection—supports plant health, enhances seed germination, and bolsters crop resilience, ultimately contributing to higher yields and better quality produce.
Operating at near-ambient temperatures, non-thermal plasma generates reactive oxygen and nitrogen species without the need for additional chemicals. This makes the technology particularly suitable for seed treatment and wastewater purification, all while maintaining energy efficiency. The system’s ability to function under mild conditions not only reduces operational costs but also minimises environmental impact, aligning with global sustainability goals.
Dr. Venkateswar, who witnessed the demonstration, expressed his admiration for the innovation, describing it as “very interesting.” He commended IIT Tirupati for its practical applications of plasma science, recognising the potential of this technology to bring about transformative changes in agriculture and environmental management.
The implications of this breakthrough are far-reaching. For farmers, the technology offers a cost-effective and eco-friendly solution to enhance crop productivity and ensure food safety. For policymakers, it presents an opportunity to promote sustainable agricultural practices and reduce the environmental footprint of the sector. Moreover, the decentralised nature of the plasma systems means that they can be deployed in various settings, from small-scale farms to large agricultural enterprises, making them accessible to a wide range of users.
As the world grapples with the challenges of climate change and food security, innovations like non-thermal plasma technology provide a beacon of hope. By harnessing the power of plasma science, researchers at IIT Tirupati are paving the way for a more sustainable and resilient future, one that balances the needs of agriculture, industry, and the environment.
