System Overview
Stage I:
Infectious waste to be treated is loaded into the system, either
by a controlled feed belt or cart-dump batch system where it is
carried and dropped into a rotating multi-stage vertical shredding
mill or high performance shredder. The opening of the machine is
large enough to accommodate any standard size red-bag and the waste
does not need to be separated.
Stage II:
The maceration, volume reduction and disfigurement process begins
by means of a 3-stage impact mill or optional high performance-shredding
device. The material is shredded until it is rendered into a fine,
unrecognizable product, which is then moved by high volume airflow
or a screw conveyor into the mixing drum via a connecting material
tube.
Stage III:
The treatment chemical is sprayed onto the waste material as it
exits the maceration device and enters the rotating mixing drum.
This pressurized "kill tank" is where the full treatment and decontamination
take place. At the end of the mixing period, the drum is then pressurized
to insure complete disinfection of the waste material. The pressurization
stage of the system can also be upgraded to utilize steam as the
medium, and incorporate autoclave treatment into the system.
Stage IV:
At the end of the pressurization cycle, the drum rotation is reversed
and the sanitized waste material exits the drum onto the outlet
conveyor to be discharged from the system. It is now safe to put
into a dumpster or compactor for transport to the landfill.
The entire process is automatically controlled by the PLC for optimum
performance, and an integrated negative air system with final HEPA
filter insures air quality. The LFB 12-5 system operates on the
same principals in all models:
1) Delivery of waste to the maceration device.
2) Waste and chemical, weight accountability.
3) Maceration, size reduction and disfigurement.
4) Conveyance, chemical injection and mixing.
5) Safe containment and mix in the kill tank.
6) Enhanced disinfection and pressurization.
7) HEPA filtered negative air system.
8) PLC automated control.
9) Durable and maintenance friendly.

System Advantages
The LFB 12-5 combines
the highly effective combination of sodium hypochlorite and pressure
with a high-speed maceration device to render infectious wastes
unrecognizable and non-infectious.
* The system is fully automated, requiring only one person to operate.
* Processing capability up to 1,500 pounds per hour or more.
* No separation of sharps and path waste for expensive individual
pickup.
* System accepts ALL infectious waste (excluding chemotherapy).
* All medical waste is converted to ordinary waste and hauled at
general waste prices.
* All waste is 100% treated and is suitable for general landfill
disposal.
* All waste is rendered into unrecognizable granular debris to extensively
reduce contact incidents.
* Volume reduced by 90%.
* A full capacity load can easily be processed in less than one
hour, with the "automated batch mode" feature.
* Material can also be processed as it becomes available with the
"on-line mode" feature, which eliminates the need for pre-treatment
storage.
* Any interruption of service by any of the subsystems will halt
the process and alert the operator of the specific problem.
* The entire system operates under a negative airflow, and all air
is filtered through a HEPA final stage filter; assuring operator
and environmental safety.
* A sophisticated Electronic Control System insures proper chemical
to waste ratio, and maintains total system integrity.
* Fixed base and mobile systems available.
Not only will these features allow reduction of hauling and disposal
costs, but also create invaluable savings associated with liability
reduction, a safer workplace and a cleaner environment. Compared
to incineration, the LFB 12-5 technology is a much more efficient,
safer, and environmentally conscious alternative.
