MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202541115068 A) filed by Nandha Engineering College, Erode, Tamil Nadu, on Nov. 21, 2025, for 'a portable straw system that uses biodegradable bamboo and incorporates microfiltration for electricity- free drinking water purification.'
Inventor(s) include P Shanmugam; T Sathish; T Nithish Kannan; S Dheenadhayalan; D Rigan; D Peer Mohamed; and M Idhikash.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "Access to safe drinking water continues to be a critical global challenge, particularly in rural communities, disaster-affected regions, and off-grid environments where conventional water purification systems are either inaccessible or unaffordable. Many available purification methods require electricity, chemical treatment, or established infrastructure, making them unsuitable for field-based and emergency use. Portable filtration straws exist, but they are commonly made from plastic materials that are non-biodegradable, costly to replace, and contribute to long-term environmental waste. Therefore, there is a need for a sustainable, low-cost, and user- friendly water purification alternative that can be used instantly at the point of consumption. This project introduces a bamboo-cased portable microfiltration straw designed to purify contaminated water simply through suction. The internal microfiltration membrane removes particulate impurities and harmful microorganisms, allowing users to drink safely from natural or untreated water sources. The bamboo casing serves as a fully biodegradable and renewable structural housing, replacing plastic components while offering natural strength, antibacterial properties, and local availability. The device requires no electricity, chemicals, or maintenance, making it suitable for daily use in rural households as well as for travelers, trekkers, military personnel, and disaster relief operations. The proposed system combines traditional eco-friendly materials with modem filtration technology, providing a practical, efficient, and environmentally responsible solution to drinking water challenges. By enabling decentralized and sustainable water purification, this innovation helps support public health, environmental conservation, and community resilience, while contributing to global goals of clean water access and reduced plastic waste."
