WTK EcomaS 100 medical waste treatment system

Infectious risk hospital waste steriliser and shredder systrem

SCROLL

WTK EcomaS 100 enables hospitals to treat their solid infectious waste in a sustainable and cost- effective way: a revolutionary solution that shreds, sterilises and compacts infectious hospital waste, eliminating the need for storage, transport and incineration.

WTK EcomaS 100 allows the treatment of the following waste categories:

  • CER 18.01.01 / CER 18.02.01: sharps (unused sharps)
  • CER 18.01.03: waste that must be collected and disposed of using special precautions to prevent infection
  • CER 18.02.02: wastes whose collection and disposal is subject to special requirements in order to prevent infection

Technical specifications

The sterilisation treatment takes place inside the TRAMOGGY during the grinding phase.
No chemicals are used. WTK EcomaS 100 is equipped with an air heater that allows hot air into the TRAMOGGY. The temperature of the TRAMOGGY reaches 150 o . Once this temperature is reached, the TRAMOGGY is pressurised to 3 bar. This dual activity enables the sterilisation action of the waste, which is simultaneously shredded. Heat transfer occurs by convection.

The shredding of waste takes place by means of a dual process, within the same TRAMOGGY and sterilisation. An initial ‘coarse’ shredding takes place by means of a shredder with 2-axis cutting blades that is placed near the loading compartment. The shredded waste, by dropping down, passes into the lower compartment of the TRAMOGGY and arrives at the second ‘finer’ shredding stage, by means of a second hammershredder.

Before the shredded and sterilised waste is ejected from WTK EcomaS 100, it must necessarily be cooled. This is done by suctioning the processed waste from the TRAMOGGY to another STORAGE container. Suction is achieved by means of an air vacuum. Once the waste has reached the STORAGE container, it is continuously stirred by the movement of air in the form of a vortex. In this way, the temperature is reduced and hot, potentially unhealthy air is expelled by means of filtering treatment (activated carbon and Hepa).

Once the waste residue has cooled, it is ready to be ejected from WTK EcomaS 100 in the form of a small cylindrical solid. From the cooling container, the residue passes through an automatic press that creates a cylindrical solid with a diameter of approximately 8 cm.
The solid is then ejected from WTK EcomaS 100 and placed inside a special bag for disposal.
