The MR1 system
Autonomous microwave system for treating hazardous healthcare waste with EWC codes 18 01 01 and 18 01 03*
Microwave technology
Principle of operation
The method is an alternative to the widespread incinerator and autoclave methods. It treats the waste in a microwave field, which ensures optimal heating from the inside out – a result of the high-frequency oscillation of the particles.
The unit is designed for thermal disinfection of infectious wet and/or dry waste, liquids and more. Treatment uses high-frequency microwave energy once water is added.
The process disinfects effectively even closed and hollow forms, thanks to even heating of both their surface and their interior. After treatment, the residue has the characteristics of safe municipal waste.
Four steps
How it works
1. Collection
Waste is collected directly in the MR1 container, at the place where it is produced.
2. Loading
The container is placed in the chamber with no transfer or sorting.
3. Disinfection
Once water is added, microwave energy heats the waste evenly from the inside out. One cycle takes about 35 minutes.
4. Disposal
The residue has the characteristics of safe municipal waste, and the container is reused.
Applications
What the MR1 treats
The MR1 can treat:
- Used empty blood bags
- Drainage equipment
- Needles, syringes and other single-use instruments
- Single-use protective equipment and used dressings
- Haemodialysis consumables, culture media in Petri dishes
- Other
Benefits
Advantages
- Meets all the goals in the “Human medicine waste” section of the NWMP (National Waste Management Plan)
- Collection, transport and treatment that are safe for staff, with no additional handling (transfer and sorting before disinfection)
- Waste is disinfected where it is generated – no risk is passed on to the public sector
- Waste is disinfected together with its collection containers – no chemical disinfectants are needed for the containers
- Lower overall cost of managing hazardous healthcare waste
- Capacity can be upgraded when needed
- Technological compatibility with the future construction of plants for processing and recycling non-hazardous waste
Low management cost
Lower costs
Operating costs are reduced through:
No external steam supply
Reusable container
No transport costs
Because disinfection takes place inside the hospital.
No additional chemical agents or labour for disinfecting the containers
