Biohazard Waste Treatment
Compact, Safe and Fast: a steam sterilizer specifically designed for total decontamination of hospital waste. Convert potentially infected or already infected waste into municipal waste.
The biological risk related to the management of infected and hazardous solid waste (BSL 2
÷ 4) generated by hospitals, healthcare centers, surgery clinics and BSL-rated labs can be successfully reduced to zero by means of the steam sterilization, the only thermal process capable to sterilize with a SAL of 10-6 (equivalent to a 6log bioburden reduction) any solid waste introduced inside the pressure vessel, Including bacteria and viruses.
Main features of our WaSter:
- Trituration (crushing) in vacuum
- Complete sterilization in saturated steam
- Significant reduction of waste volume
- Perfectly sealed and safe system
- Available as free-standing system and pass-through version
- Diverse customization options

Process for shredding and sterilizing waste
Thermal treatment and following decontamination take place in a perfectly sealed stainless steel vessel thus avoiding the risk of any cross-contamination.
The shredder is extremely robust and capable to significantly reduce the overall volume of the waste (which gets fragmented into very small pieces).
The shredded waste also facilitates the air removal during the application of the vacuum. This enhances the steam penetration and sterilization, avoiding any risk of residual biological contamination.
The sterilizer version with pass-through hatch (available as an alternative option to the single door vessel) allows a unidirectional pathway of the biological waste. This option is always advisable where full segregation of the loading side (“dirty” area) from the unloading side (“clean” area) is desired.

WaSter® offers four distinctive competitive advantages: (Show more)
- 80% reduction of the original solid waste volume leads to a significant reduction of the waste to be disposed
- Solid waste is completely dry, ensuring an easy and clean handling
- Location of the shredder in a sealed environment ensures safety throughout the treatment process
- The entire treatment cycle takes place inside a tightly sealed pressure vessel, thus preventing the emission of unpleasant smells.

Reliable process validation: (Show more)
Completing the validation process ensures that the design conditions are met soon after the installation. In particular, the following values are constantly checked during the sterilization cycle: pressure, temperature and the presence of non-condensable gases.
Monitoring those parameters not only guarantees the effectiveness of the sterilization process in compliance with the reference standard UNI EN ISO 17665-1:2006, but also a Sterility Assurance Level (SAL) of 10-6.

Environmental Impact: (Show more)
WaSter® was developed by applying an eco-project design, with the aim of preserving the environment in which we live. Based on the idea of producing a device with sustainable consumption to reduce the environmental impact, significant, measurable goals were set and also achieved, all of which enhance the performance of the WaSter® product line.
The vacuum is generated by an innovative vacuum pump that runs fully dry (no lubricants required) and is compatible with steam. The water consumption for vacuum generation is limited to the production of pure steam and the cooling of the discharge outlet.
1. Arrival of infected material
The infected material is collected, sealed in a transport trolley using special disposable plastic bags and placed in the area of the lifting platform. A special trolley is then loaded into the WaSter® to receive the shredded waste
2. Manual loading of infected material and cycle start
The transport trolley containing the infected material is lifted to the correct loading level via the integrated lifting platform. The waste is loaded manually: after loading, the chamber is hermetically sealed and the cycle begins.
3. Unloading of the sterilized material
The trolley containing the shredded and sterilized waste is unloaded from the clean side of the WaSter®
