“Which one is more effective and efficient?” The AIIMS, New Delhi, India procured the Microwave Assisted Cold Sterilization (MACSTM) technology called OptiMaser® as an alternative to autoclave for their on-site biomedical waste treatment.
Study
ICMR Validates OptiMaser for Clinical Efficacy of 99.99% with >Log 7 sterilisation “It is a high level steriliser capable of disinfecting & ensuring >7 log reduction in Bio-medical Waste which inlcudes pathogenic bacteria, pores, yeast & fungi, viruses & Mycobacterium Tuberculosis”. Report No. SCTIMST/ICMR/SD/Req. No. 59 Dated 06.05.2022
“OptiMaser® 30 is a popular commercial microwave technology used for sterilisation of clinical biomedical waste. The study was conducted to evaluate the effectiveness of Microwave as an alternative method to autoclaving for sterilising large volumes of sputum with viable M. tuberculosis for safe disposal”.
“The main benefit of microwave energy is the direct delivery of energy to microwave-absorbing materials, which allows the volumetric heating of samples. Issues such as long heating periods, thermal gradients, and energy loss to the environment can be minimized”.
Report on TCID-50 by Dr. T.N. Dhole
“As reported in literature one-minute exposure of Microwave can significantly kill about ninety-five percent of the virus under experimental conditions”.
Recently in 2019 an article was published in In-forma Journal of Arab Health magazine entitled “New Horizons for Medical Waste treatment Technology”. The article compares existing autoclave and the new radiation-based microwave technologies for infection control in the healthcare facilities.
“Hospital linen which are soiled discharged of infectious patients, including those with HIV, hepatitis B, C, and other infectious agents. At least 8 log disinfection efficacy of representative bacteria, fungi, and spores were achieved via OptiMaser® treatment at 70°C with a hold time of 10 min”.
“It was reported that steam autoclave effectively treated the biomedical waste samples at 121 °C for 30 min and 121 °C for 45 min but at 121 °C for 15 min it showed ineffective sterilization. Microwave completely destroyed all forms of microorganisms and provides effective sterilization at temperature of 70 °C to 100 °C, frequency of 2450 MHz and cycle of 30 min”.
