What material can Sterimelt process?
Sterimelt can process uncontaminated non woven (SMS) polypropylene wraps, drapes (in single or double ply), patient transfer sheets, disposable pillow cases, bouffant caps and headgear.
Sterimelt has been tested using Halyard Health (HYH), Clinipak and Westfield Medical clinical sterilisation wrap products and MIP UK patient transfer sheets (JC-100).
What about different colours?
The colours do not matter, and can be processed as a mixed batch.
How many wraps can be placed in Sterimelt?
It does depend on the size of the sheets, but as a guide between 120 and 150 large sheets at a time.
Some hospitals prefer to collect the sheets in plastic bags, Sterimelt will take between 6 and 8 full 30litre bags.
How does Sterimelt process the waste wraps?
Sterimelt uses thermal heater plates to densify and “re-engineer” the original manufacturing process. Sterimelt is well insulated and the outside casing is safe to touch, however, it may also feel warm to the touch.
Do the plastic wrap sheets burn?
No, Sterimelt uses carefully controlled heat to allow the plastic to melt into a solid block, in a safe and compliant manner.
Does the melting plastic give off an odour?
All plastic polymer gives off an unfamiliar poly-aromatic odour when heat is applied. Sterimelt uses a carefully selected filter system to absorb all bar the faintest trace of odour’s. The emissions have been tested independently and verified as less than normal particles found in the atmosphere daily.
How long does it take to process?
In June 2019 a new cooling system has been introduced to Sterimelt, getting the cycle time down to below 1 hour. Process cycles can be affected by the external ambient temperature too.
Will Sterimelt need constant supervision waiting for the process to complete?
No, once loaded, which takes less than a few minutes, the operator presses one button to start Sterimelt and is then free to carry on performing other duties. It would be similar to throwing the waste bags into a skip.
Where would the Sterimelt be located?
Sterimelt is designed for internal or external use. It needs to vent to atmosphere. It has an IP54 outdoor electrical rating and is constructed from Stainless Steel. Ideally Sterimelt should be sited in the waste compound of the customer or close to where the wraps are segregated.
What happens to the blocks?
The blocks are 100% polypropylene when processed and have commercial value, so can be used in the UK to make new products. They are inert, impervious to the elements or infestation and are odourless and sanitised. This means they can be safely stored outside on pallets, until a load is ready. This significantly reduces transport movements onto hospital sites. We have had the blocks independently analysed and confirmed sterile when they exit Sterimelt.
What happens if the Sterimelt breaks down?
Sterimelt is fitted with telemetry in order for our engineers to remotely access the machine for fault finding purposes or routine interrogation. Should we not be able to repair Sterimelt by remote access, then an engineer will be dispatched promptly, this is usually within 48 hours. The telemetry uses SIM card technology and is NOT connected to the customers digital network.
What would happen if some contaminated wrap was placed in the Sterimelt?
Nothing, the heat used to process is way in excess of Autoclave limits and therefore would sterilise anything that may be contaminated and accidently placed in Sterimelt.
What is the size of Sterimelt?
Sterimelt has a footprint of 2 square metres and stands 2 metres high. It weighs approx 450 kgs.
How much does it cost to run?
Sterimelt uses a 32 amp, 3 phase, 415V electrical supply. Running costs will depend on individual energy supplier tariffs,
but for an average business the running cost would be approximately £0.90p per hour.
If the customer had its own energy generation system or biomass type plant with CHP, costs could be as low as £0.10 per hour.
Can it process other types of plastic waste?
It can only process flexible non woven (SMS) polypropylene.
Will Sterimelt need any special Environmental Licence?
No. It can run under a normal waste operations licence or simple S2 exemption licence and
is covered in England and Wales by E.A. Position Statement 112.
How heavy are the blocks?
The blocks weigh approximately 20kg or lighter.
