Converting Pathogenic Biomedical Waste into Value-added Soil Additives and its Automation

CSIR-NIIST’s automated biomedical waste conversion technology offers a safe, non-incineration, and environmentally sustainable alternative for the management of pathogenic biomedical waste. The technology eliminates harmful emissions associated with conventional incineration, minimizes human intervention, and converts infectious waste into non-toxic, value-added soil additives while enabling direct recycling of disinfected laboratory disposables. By reducing transportation needs, occupational exposure, and environmental pollution, the solution addresses a critical national challenge in biomedical waste management and supports compliance with WHO-recommended innovative disposal protocols.

The technology is designed for on-site treatment of pathogenic biomedical waste generated in hospitals, laboratories, research institutions, and healthcare facilities. It can process infectious materials such as blood, urine, sputum, and laboratory disposables through an automated disinfection and immobilization process, rendering the waste non-hazardous. The treated output is odor-free, antimicrobial-neutralized, and suitable for conversion into soil-enhancing additives, while plastic laboratory disposables can be directly recycled. The system has undergone expert third-party validation, soil performance assessment, and first-stage field validation at AIIMS, New Delhi, demonstrating its applicability for large healthcare establishments.
