Sterilwave 250 - Bertin medical Waste


Sterilwave 250

With a waste treatment capacity of 50 kg per hour, the Sterilwave 250 allows medium-sized institutions to treat their biomedical waste, guaranteeing safety and traceability at greatly reduced operating costs.

The Sterilwave 250 was approved by the French Ministry of Health in 2014 and complies with the strictest environmental and bacteriological reduction standards. It allows institutions to treat up to 500L of biomedical waste per hour (50kg/hr*) in complete safety.

Its innovative concept uses rotating grinder blades to grind down all types of waste, including metallic objects. Biohzardous waste is sterilised using microwaves and converted into inert municipal waste, reducing its volume by more than 80% and its weight by 25%. Its environmental impact and operating costs are reduced while ensuring the safety of the operator. As it uses microwave technology, Sterilwave does not need a steam generator, so there is no risk from excess pressure and no liquid effluent is produced. Its compact size means waste can be treated immediately where it is produced. Its installation requires only 12m² of space and no additional infrastructure.

Process management

Full traceability

Full decontamination

Biohazardous waste is sterilised with microwaves (heat it up to 110°C for 20 minutes) and allows microbial inactivation of up to 8log10

Safe processing

Microwave sterilisation technology does not require pressurisation, and this removes any risk of explosion. Moreover, the microwaves are confined to the inside of the vessel to avoid operator exposure to radiation

No liquid effluent

The treatment process does not produce any steam or liquid effluent, which means no consumption of water and no need to include an effluent drainage system in its installation

No segregation

The Sterilwave is suitable for all types of biomedical waste (needles, glass, solids, liquids, etc.)

Easy maintenance

The equipment is built using robust technology. IP connection for diagnostics. Preventive maintenance plan/calendar with alarm

Reduces weight by 25% and volume by 80%

Biomedical waste is converted to inert waste similar to municipal waste. The dry ground-up waste can also be used as secondary fuel

With its automated grinding and microwave sterilisation process contained in a single vessel, the Sterilwave can produce bacterial inactivation (higher than 8log10) of biomedical waste in less than 30 minutes, in complete safety and without intermediate handling. Unlike autoclave technologies, our system does not require the vessel to be pressurised. The Sterilwave converts biomedical waste into dry waste which is inert and completely disinfected, reducing its weight by more than 25% and its volume by 80%. The end product is similar to municipal waste and can then be fed into standard urban waste systems.
