Dr. Jitendra Singh, the Union Minister for Science and Technology, recently launched the first experimental prototype of an automated biomedical waste conversion system at All India Institute of Medical Sciences (AIIMS). This innovative technology, developed by the National Institute for Interdisciplinary Science and Technology (CSIR-NIIST) in Thiruvananthapuram, is designed to disinfect pathogenic biomedical waste (such as blood, urine, sputum, and lab disposables) and convert it into soil enhancers.
Named “Sṛjanam,” the system offers a more efficient and environmentally friendly alternative to costly and energy-draining incinerators. It even helps eliminate the unpleasant odor of hazardous waste. The initial prototype can process up to 10 kg of biodegradable medical waste per day, with a total daily capacity of 400 kg. Once fully validated, this system will be scaled for widespread use, pending approval from relevant authorities.
During the commissioning event at AIIMS, Dr. Singh highlighted the growing challenge of biomedical waste in India. In 2021-22, the country generated 700 tonnes of biomedical waste daily, which increased to 743 tonnes per day the following year. Quoting WHO data, Dr. Singh pointed out that hospitals in India generate between 0.5 to 0.75 kg of pathogenic biomedical waste per bed daily, all of which is infectious and poses significant health risks to nursing staff.
Dr. Singh emphasized that the government’s decisions are driven by technology, which is transforming India into one of the world’s largest economic powers. He underlined the need for effective waste disposal systems to keep pace with the country’s rapid growth.
The event was attended by several dignitaries, including Tanmay Kumar, Secretary of MoEFCC, Dr. N Kalaiselvi, Secretary of DSIR & DG of CSI, Dr. Rajiv Bahl, Secretary of DHR & DG of ICMR, Dr. V K Paul, Member of NITI Aayog, Dr. M Srinivas, Director of AIIMS New Delhi, and Dr. C. Anandharamakrishnan, Director of CSIR-NIIST.
Dr. Kalaiselvi highlighted that this project is a part of the government’s “Waste to Wealth” mission. The technology converts 10 kg of biomedical waste into bio-manure within just 30 minutes without harming the environment (water, air, or soil).
Dr. Anandharamakrishnan concluded the event by stating, “Our technology offers a safer waste disposal solution for healthcare facilities, minimizing human intervention and reducing the risk of spills and exposure, while also preventing the spread of infectious microbes.”
