Newster ® is a patented technology for the treatment of potentially infectious solid hospital waste based on high thermal treatment, without burning. The residue obtained is sterilized, finely treated, dried and reduced in weight/volume.
 The treatment principle is tested, patented, certified and it is the most valid alternative currently availa­ble to traditional disposing methods like incineration.

How does Newster® work?

The mechanical energy produced by the electric motor is the heating system of the machine. The rotor grinds the waste down and supplies, via friction and impact, the kinetic energy. The energy produced induces the tempera­ture required for sterili­zation. (It is possible to feel the same kinetic force by rubbing and clapping your hands together). Thus, the Newster system does not need pressurised steam inside the cell to reach high enough temperatu­res. Everything is carried out in a single depres­sion cell thereby avoiding any risk to the environment and the operator. With the Newster system the wastes are finely shredded to permit uniform penetration of the heat, therefore the particles are heated to their core and not only to the outer surface; the temperature reaches 150°C, a level highly lethal for micro­organisms and bacteri­as, at the same time a computer controls the exposure period.

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 sized room.

It can be equipped with weighing and bin cleaning systems upon demand and a fee.

The connections required, except power supply, are very similar to the connec­tions required for a domestic washing machine; The technology is easy to use and can be conducted by an unskilled operator; the machines' downtime risk is minimum.

time. These three parameters together ensure a high level of sterilization.



The operator loads the cell with health care wastes, closes the lid and presses the start cycle button.

Initially (1) the rotor rotates slowly and grinds the material; the temperature increases.

When the material is shredded, the rotor increases speed and the temperature rises until the evaporation phase (2).  The temperature remains steady until the humidity has evaporated.

When this phase finishes, the temperature increases again to 150C (3). Then the mass of wastes is cooled by water until it reaches 95C (4). The cycle is now completed. The product, now sterile, is automatically unloaded (5) and the system is ready 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.

The use of on-site technologies allows a remarkable reduction of the facilities' costs for disposal, incre­ases the hygiene quality, improves the safety of the personnel, contributes to reducing produced waste quantity and also reduces the environmental impact to near zero in accordance with the trend of reduction of environmental emissions and risks arising from the transport of infectious waste.

During the cycle the thermal decomposition of proteins through reaction with water and the break-up of cell membranes processes occur simultaneously to ensure the effectiveness of the sterilization.


The running costs inclusive of energy consumption, mainte­nance, operating staff and consumables allows a significant reduction of the cost of disposal.
