Microbial Inactivation by microwave radiation - Bertin medical Waste

Microbial Inactivation by microwave radiation

The microwave technology used by the Sterilwave is recommended by the WHO (World Health Organisation) and validated by numerous countries. It allows biomedical waste to be treated in complete safety without any need for pressurisation of the vessel, produces no liquid effluent and complies with environmental requirements.

The Sterilwave solution for disinfecting biomedical waste is based on microwave technology, which is the most eco-friendly method available. This technique allows microbial inactivation of biomedical waste in 30 to 35 minutes.

Unlike autoclaves, this process does not require pressurisation, and this minimises any risk of explosion due to poor maintenance and training of operators. All types of biomedical waste (solids, liquids, glass, sharps, blades, etc.) can be treated with the system, and the entire process is traceable. Besides the rapid and effective decontamination of biohazardous waste to an inactivation level greater than 8log10 (sterilisation level), the Sterilwave also converts biomedical waste into dry, inert material and reduces its weight by more than 25% and its volume by 80%. This resulting material is similar to municipal waste and can also be used as secondary fuel with a high energy output.

The best alternative to autoclave and incineration solutions – detailed comparison:

AUTOCLAVE INCINERATION STERILWAVE
Technology Temperature under pressure over 130 °C Require a steam-powered generator Incineration on specific location. Require special carrier (expensive) Based on microwave technology, simple and efficient (heating at 100°-110°C) More efficient than Autoclave technology ( confirmed by OMS)
Pressure / authorization Risk in case of error

Working under pressure (several bars of saturated steam);
Specific authorization to work under pressure;
Require many maintenance tasks;
High risk in case of human error

NC Ambient pressure Safe to operate and maintain Limited Risk in case of Human error
Integrated grinding system Slow shredding <20 mm output size No Yes by rotate blade: 1500 RPM <10mm output size
Disinfection efficiency from 5 log to 8 log10 (depending the brand model) Complete destruction Over 8 log10 more than 6 log 10 for virus
Output Waste after treatment Volume reduction up to 80%;
Wet waste;
