Indian scientists from CIPET, SRMCRI develop tech to safely dispose of biomedical & hospital waste

New Delhi: Researchers from Sri Ramachandra Medical College and Research Institute (SRMCRI), and Central Institute of Plastics Engineering & Technology (CIPET) Guindy, Chennai, have developed a series of technologies for the safe disposal and management of hospital waste. These include a technology to decontaminate used sharp items present in hospital waste, a sensor operated waste bin to absolve the necessity of waste disposing staff touching the bins, and specifications for universal sample collection containers which make the sample non-toxic when it is disposed as waste.

Professor Padma Srikanth, Dept. of Microbiology at SRMCRI, and K. Prakalathan from CIPET jointly developed these series of technologies, whose applications in a hospital can be a comprehensive hospital waste management solution.

These technologies, developed with the support of Waste Management Technologies (WMT) Program of the Department of Science & Technology (DST), Government of India, can be used in Primary Health Care Centres and Hospitals.

The sharp items disposal container is a non-manipulative device and stands out for its capability of onsite decontamination of used sharps. It has a unique provision for mutilation of sharps and chemical treatment at source, is in compliance with Biomedical Waste Management Rules 2016 and amendments of March 2018, and is ready for Technology Transfer.

The sensor in the sensor operated bin works for non-contact disposal of hazardous waste such that it is a non-touch technique. The bin will open automatically, and shut automatically after the bin is three fourths full, preventing spillover of waste. A prototype of the Sensor Operated Waste Bin which holds special features for automatic open and closure of lid for disposal of waste has been validated. It avoids overflow of medical wastes by inputting a specified filling limit and locks the lid, and intimates to clear waste every 24 hours.

The universal sample collection container whose specifications have been framed is of uniform size, shape, and material, unlike those currently available in the market. Generally sample collection containers are made up of inferior grade plastics. They are used for storing biomedical waste, and the plastics release several biotoxins dangerous for the environment when they are destroyed in autoclave machines.

Developing specifications for the plastic used in the container with a universal shape and material, and getting National Accreditation Board for Testing and Calibration Laboratories (NABL) approval will prevent environmental damage.

The technologies have been validated with analyses for Log 10 reduction of HIV, Hepatitis B, and Hepatitis C viruses using laboratory techniques of Reverse transcription polymerase chain reaction (RT-PCR) (Rotorgene).

Patents for these technologies for Hospital Waste Management have been filed and they have a huge market potential owing to the high demand for cost effective and non manipulative disposal of sharp items in hospitals and clinics.

The team is working to develop hundred sharp items disposal containers and sensor operated bins to be installed at local healthcare centres for further improvement, if required, and obtaining Bureau of Indian Standards (BIS) approval for making Indian standards for manufacturing of sample collection container with a universal shape, size and material under NABL and international guidelines.
