Indian Scientist Patents Device to Capture and Sort River Microplastics

A researcher from the University of Mumbai has secured an Indian design patent for a device that captures and sorts microplastics from rivers. Dr. Pandurang Yashwant Patil developed the technology, which targets particles smaller than five millimetres. The achievement highlights the university’s ongoing efforts to tackle environmental challenges.

The newly patented device, named the 'River Microplastic Capturing and Sorting Device', uses a multi-stage filtration system. It first separates organic waste from plastic before sorting the microplastics through a structured mechanism. This innovation is particularly important for the river ecosystems of Ratnagiri and the Konkan coast, where clean water is essential for biodiversity and local communities.

The Department of Environmental Science at the Ratnagiri Sub-campus has long focused on air and water quality research. Dr. Patil’s work builds on this foundation, offering a practical tool for river conservation. The patent represents the first official step towards manufacturing the device and applying the research in real-world settings.

Future plans include upgrading the system with solar power, smart sensors for automatic filter cleaning, and real-time monitoring. These enhancements aim to improve efficiency and adaptability. The University of Mumbai’s Vice-Chancellor, Pro-Vice-Chancellor, Principal, and Registrar have all congratulated Dr. Patil on this accomplishment. The patent strengthens the university’s reputation for developing scientific solutions to environmental issues. The device is expected to play a key role in protecting river ecosystems in Ratnagiri and the Konkan region. Manufacturing and further development will now move forward as the next phase of the project.
