The Newster® cycle process
The operator loads the cell with health care waste, closes the lid and presses the start cycle button.
1st Phase, Loading and starting: a powerful rotor, fitted with
stainless steel blades starts rotating slowly and grinds the material while the temperature increases. When the material is roughly shredded, speed increases and
temperature rises untill the evaporation phase starts.
2nd Phase, Evaporation of liquids: the temperature remains steady untill the humidity has evaporated.
3rd Phase, Achievement of required sterilization temperature: the temperature increases again to reach 150 °C, the exact degree in order to sterilise.
4th Phase, Cooling: the waste is cooled by brief sprays of water until it reaches 95 °C.
5th Phase, Unloading: the cycle is complete. The processed waste, now sterilised, is automatically unloaded. During the whole cycle the temperature of the
wastes is measured in real time and with great accuracy by patented sensors.
The product, by now sterile, is automatically unloaded (5) and it is time to run a new cycle. During the whole cycle the temperature of the wastes is measured in real time and with great accuracy by patented sensors. As the process proceeds the system automatically prints a report with essential parameters which the operator will attach to the work sheet at the end of each cycle.
How does Newster® work?
Newster is a frictional heat treatment technology. In a closed sterilisation chamber a powerful rotor fitted with blades treats the waste by impact and friction,
grinding it finely. The energy produced induces the temperature required for sterilisation. For this reason Newster process does not require pressure steam inside the
chamber to reach the temperature of 150 °C. The time of heat exposure and the cycle parameters are controlled by a PLC. During the cycle, the temperature inside the
chamber is accurately measured in real time by patented sensorsThe treatment process is carried out in a single depression chamber, thereby avoiding any risk for the environment or the operator. The Newster system finely shreds waste to allow a uniform penetration of the heat. The particles are heated to their core and not only on
the outer surface, for a time lapse long enough to destroy microorganisms and bacteria.No chemicals are used to achieve sterilisation of the waste. Sterilisationis proven by microbiological analyses on the residue and efficacy tests using biological indicator containing Geobaciullus Stearothermophilus ATCC 7953 spores with a concentration of Log6.
Easy to use, inexpensive and suitable for hospital needs
The equipment is tailored to the needs of the healthcare facility and can be installed on site in a small size room. It can be equipped with weighing and bin cleaning
systems. Electrical connections, water supply, and sewage collection are required. The technology is easy to use. An operator with basic skills and a two to four day training course provided by Newster can easily operate the unit. Training for the service and maintenance staff is also provided, reducing the machine’s downtime.
The running costs, inclusive of energy consumption, maintenance, operating staff and consumables, allow a significant reduction of the cost of waste disposal (in Italy between 50% and 70%).
