Newster’s Frictional Heat Treatment enables hospitals to process hazardous solid waste in a sustainable and cost-effective way. The patented technology employs the heat generated by the shredding action to sterilize the waste at the same time without POPs emission into the athmosphere according to the Stockholm Convention. The final residue is dry, sterile and finely ground.
As well as meeting the public demand for ecological solutions, it offers many other advantages, such as:
Frictional Heat Treatment Process
The treatment is carried out in a single depression chamber without risks to the environment and the operator. No chemicals are used. During the cycle, the temperature inside the chamber is accurately measured in real time by patented sensors. The duration of the exposure to heat and the cycle parameters are controlled by a PLC. During the cycle, the system automatically generates a printed report, which the operator attaches to the work sheet at the end of each cycle. Sterilization can be proven by microbiological analysis on the residue and by efficacy tests using biological indicators containing Geobaciullus Stearothermophilus spores with a concentration of 106.
STAGE 1: loading and starting
To begin the process, the operator loads the chamber with healthcare waste, closes the lid and presses the cycle start button. Inside the closed sterilization chamber, in negative pressure, a powerful rotor fitted with stainless steel blades finely shreds the waste by impact and friction.
STAGE 2: evaporation of liquids
As the material is roughly shredded, speed and temperature increase to 100°C, the evaporation phase starts. The temperature remains steady until all the humidity has evaporated.
STAGE 3: reach required sterilization temperature
When the humidity has been eliminated, the temperature starts to rise again reaching a peak of 150°C, as required for a complete sterilization according to STAATT Level IV. The finely ground waste is heated to its core and not only on the surface, for the time required to completely destroy microorganisms and bacteria.
STAGE 4: cooling
The waste is cooled by sprays of water until it reaches a temperature of 95°C necessary for discharge.
STAGE 5: unloading
The cycle is over and the treated waste is automatically unloaded. The sterile, finely ground, dry and unrecognizable residue is significantly reduced in weight and volume.
