AMTH- Biomedical Waste Management: An IoT- Based System for Biomedical Waste Management Including Ayurveda Hospitals

FIELD OF THE INVENTION

Our invention "AMTH- Biomedical Waste Management" is related to an IoT- Based System for Biomedical Waste Management Including Ayurveda Hospitals. A comprehensive medical waste management system for establishing and maintaining medical waste preparedness and cradle-to-grave medical waste asset management in non-emergency and emergency situations requiring medical waste assets and asset management, and methods for making and using same. A comprehensive medical waste management system for establishing and maintaining medical waste preparedness and cradle-to-grave medical waste asset management in non-emergency and emergency situations, where the system includes at least: a control subsystem, a are housing subsystem, a distribution subsystem, a tracking subsystem, a retrieval subsystem, and a disposal subsystem. The present invention also relates to methods for making aspects of the system, for implementing the system and for using the system.

BACKGROUND OF THE INVENTION

Medical waste, as generated in medical, veterinary, dental and laboratory facilities, includes a wide variety of materials and substances, including bandages, gloves, infusion bags, hypodermic needles, syringes, products of dialysis, testing vials, plastic bags, tubes, containers, blood, human and animal wastes. Medical waste must be disposed in a safe, expeditious and hazard-free manner. In large medical facilities, the medical waste is generally collected at a central location and treated by incineration or steam disinfection before disposal into a landfill. Such processes are not only costly, but may also be environment-unfriendly in pollution generated during treatment, their reliance upon transportation of the waste to an offsite treatment facility, and in the less- than-optimal use of environmental un-renewable resources.

Because of the different types of medical waste to be disposed, a number of devices have been developed which include shredders for shredding the medical waste in order to reduce the overall volume and to facilitate sterilization or disinfection. U.S. Patent Nos. 5,620,654 and 6,494,391, the entire content of both being incorporated herein by reference, relate to equipment having a footprint with sufficiently small dimensions facilitating installation in hospital departments or wards, laboratories or clinics for on-site treatment, disinfection, and localized disposal. Such systems relate particularly to a method and equipment for automatically grinding, sanitizing and neutralizing both acid and basic medical waste, and for disposing it after treatment.

The '654 Patent discloses equipment mounted in a tightly closable housing provided with charge and discharge openings. The housing contains a shredder for comminuting the inserted raw waste and for conveying the shredded material to a mixing vessel where it is diluted with water and thoroughly mixed. A container storing tubes filled with several kinds of sanitizing materials is configured to dispense the required number and kinds of tubes into the shredder in accordance with the pH value of the mixture. The pH level is communicated to a selective valve mechanism by a sensor attached to the vessel. The equipment further includes a pump for recirculating liquid from the vessel to the shredder, and a pump for draining fluid from the mixing vessel. A conveyor (25) conveys the sanitized waste out of the vessel and out of the housing. Electronic and control equipment is provided for operating the various components.

While the invention described in the '654 Patent has been incorporated in commercial settings, such apparatus is relatively large and costly, and therefore has been found to be more suitable for relatively large medical facilities, such as large-size and medium size hospitals. The '391 Patent improves upon the teachings of the '654 Patent by providing medical waste treatment equipment suitable to relatively small facilities, such as medical, dental, dialysis and veterinary clinics. To achieve this goal, such equipment includes a treatment vessel having an open top, pivotal within a housing, between a waste-loading position, a waste-treating position and a waste- removing position. In the waste-loading position, the open top of the treatment vessel is aligned with the housing inlet for receiving the waste. In the waste-treating position, the waste is shredded by a shredder unit disposed within the treatment vessel, and in the waste removing position, the open top of the vessel is aligned with the housing outlet for removing the shredded waste. The apparatus further may additionally include a compactor head for compacting the waste within the treatment vessel, a water feed line, and a disinfectant feed line, for feeding water and a disinfectant into the treatment vessel, and a mixer for mixing with the waste while it is being compacted and shredded.

Within the medical field, and especially in hospital environments, controlling the spread of potentially pathogenic organisms is an important concern. A number of studies have shown that the risk of infection due to the spread of disease organisms is a serious human health problem. Infections can be transferred by contact with surfaces upon which organisms can be deposited by handling by patients or hospital staff, or by airborne dispersion after a cough or sneeze. The risk of infection is further exacerbated by the confined space of typical hospitals, and by the fact that people in hospitals may have an impaired ability to resist infection due to their own health problems. In some cases as well, the infectious organisms are sometime resistant to commonly used antibiotics, so called super-bugs, and so remediation of the infection through medical intervention may be difficult, if not impossible. As a result, it is common practice in modern day medical setting to take appropriate measures to reduce the risk of infection. Such measures include "hand washing after contact with patients, frequent cleaning of floors, walls and furniture with disinfecting solutions, and the use of disposable products. The use of disposable plastic syringes, cutlery and beverage containers are but a few examples of products designed for single use in order to reduce the risk of spreading pathogens, and which through use become biomedical waste.

Biomedical waste also comprises such things as blood and blood products, tissues resected during surgery, as well as single use items used and discarded in the normal course of surgical procedures. It is well-recognized that contact with, human fluids such as blood is a significant risk factor in the spread of the human immunodeficiency virus (HIV) that causes the disease acquired immune deficiency syndrome (-AIDS).

It is well recognized that health hazards are posed by the handling and disposal of biomedical wastes, and that care must be exercised in handling such waste and in the disposal thereof. It is desirable and mandated in many jurisdictions that biomedical waste be processed, typically by incineration, to destroy pathogens. Incineration requires significant amounts of energy, and also releases potentially harmful combustion products into the atmosphere. Alternatively, chemical sterilizing solutions can also be used to destroy pathogens in biomedical waste. These chemicals, being themselves toxic, pose added risks to those whose responsibility it is to handle biomedical wastes, as well as a risk to the environment upon their disposal.

Ozone is also well known as having disinfecting properties, and is well "known as a sterilizing agent in certain applications. Ozone is considered very safe as evidenced by the approval of the U.S. Food & Drag Administration for use in treating food products. Ozone is a chemically active radical species of oxygen, commonly produced by ionization of either air or pure oxygen. Unlike conventional disinfecting chemicals, ozone does not form hazardous disinfectant by-products that are harmaful to the environment or are toxic to animals and humans. Once ozone has fully reacted with substances in water or air, excess gas decomposes quickly to normal oxygen and is reabsorbed into the atmosphere. Commercial ozone generators are available which economically produce significant amounts of ozone.

The use of ozone in the disposal of biomedical waste is disclosed in a number of prior art patents. United States Patent Numbers 5,078,965 and 5,116,574 to Pearson disclose grinding the waste and adding water to create a slurry over a fluidized bed, and then bubbling ozone up through the slurry. The systems disclosed in United States Patent Numbers 6,494,391 to Mosenson and 5,820,541 to Berlanga Barrera similarly add water to the ground waste, and add a disinfectant such as ozone, to the mixture. United States Patent Number 5,520,888 to Berndt uses a slush or slurry of waste and ice containing ozone to sterilize medical waste.

Largely for reasons of economy, present waste practices in hospitals and the like include segregation of waste into general waste and biomedical waste with the biomedical waste being processed as such, and the general waste being processed as ordinary garbage and taken to landfills and disposal sites with no treatment. Typically, biomedical waste must be packaged and transported according to strict regulations in order to move same from the source, such as a hospital or the like, to off-site processing.

Such segregation is subject to human error, and as well general waste is often in contact with biomedical waste prior to segregation. Further such segregation lengthens the time between creation of the biomedical waste and treatment thereof. Pathogens therefore have an extended time in which to multiply prior to treatment, thereby increasing the number of pathogens that the treatment process must inactivate. As well, waste management personnel are exposed to these pathogens during the common manual separation of biomedical waste from general waste.

The invention provides, in a first embodiment, an apparatus for processing solid biomedical waste. The apparatus comprises a waste input container having an input opening in a top thereof and an output opening in a bottom thereof. An input door is operative to close and substantially seal the input opening, and an output door is operative to close and substantially seal the output opening. A shredder is mounted under the output opening and is operative to shred waste to a desired maximum size. A processing chamber is located under the shredder such that, when the output door is open, solid waste deposited in the waste input container passes through the output opening and through the shredder, and shredded waste drops into the processing chamber. A sealable discharge opening is provided in the processing chamber. An ozone gas source is connected to the processing chamber and is operative to direct ozone gas into the processing chamber, and an ozone indicator is operative to indicate a concentration of ozone gas present in an atmosphere inside the processing chamber.

The invention provides, in a second embodiment, a method for processing solid biomedical waste. The method comprises providing a shredder above a substantially sealed processing chamber; maintaining a selected concentration of ozone in an ozone rich atmosphere inside the processing chamber during shredding at a level sufficient to sterilize the biomedical waste; feeding waste into the shredder and operating the shredder to shred the waste to a desired maximum size, and allowing shredded waste to fall through the ozone rich atmosphere inside the processing chamber and keeping the waste in the processing chamber for a length of time sufficient to sterilize the biomedical waste at the selected concentration of ozone; and exhausting the ozone rich atmosphere from the processing chamber and removing sterilized waste.

The invention uses gaseous ozone in a simple system that does not require the use of slurries as in the prior art. A considerable level of automation can be provided by the inclusion of sensors and control mechanisms. The sensors operate to provide information about ozone levels in the processing chamber, or to indicate when the hopper is full or when the treatment process is complete and another batch of material can he safely added to the processing chamber.

The invention provides an apparatus that is relatively simple and easy to install and which is relatively inexpensive to operate, and allows for substantially automated and continuous treatment of biomedical waste. Biomedical waste treated with the apparatus will be essentially free from pathogens, and as such safe for disposal in municipal landfills and the like. The apparatus for practicing the method of the invention is simple and economical, such that same could be installed in a hospital or like source of biomedical waste and all waste could be processed therein. Chemicals and pharmaceuticals would still require separation; however, these wastes are not presently considered general waste suitable for conventional disposal in any event.

Implementation Flow Charts

Referring now to FIG. 6, a conceptual flow chart of the operations of the system, generally 600, is shown to include the step of receiving a request for deployment 602 from a medical response agency. Once the request for deployment is received, the system 600 receives site information 604 from the agency including number of sites, site locations, estimated size of deployment-number of people to be treated, and type of emergency or non-emergency situation. The system600 then distributes, from one or more warehousing facilities, sufficient waste management kits to each site to handle generated medical waste based on the deployment request in a distribution step 606.

As the emergency or non-emergency situation unfolds and medical waste is accumulated, the response team forwards containerized medical waste to the indicated disposal facility in a transportation step 608. In certain embodiments, the transportation step 608 includes contacting a courier such as the United States Postage Service, UPS, DHL, FedEx or the like to pick up and deliver the containerized medical waste to the indicated disposal facility. In other embodiments, the transportation step 608 includes dispatching specialized hazardous waste handlers to collect and transport the containerized medical waste of the indicated disposal facility. The system 600 also includes the step of receiving the containerized medical waste at the indicated disposal facility, in a receiving containerized medical waste step 610. The system 600 also includes the step of disposing of the containerized medical waste, in a disposal step 612, where the medical waste is disposed of according to guidelines for handling the specific type of medical waste.

Referring now to FIG. 7, a conceptual flow chart of the operations of the system, generally 700, is shown to include the step of receiving a request for deployment 702 from a medical response agency. Once the request for deployment is received, the system 700 receives site information 704 from the agency including number of sites, site locations, estimated size of deployment-number of people to be treated, and type of emergency or non-emergency situation. The system 700 also includes the step of processing the deployment request and site information at a central command and control facility, in a processing step 706, where the command and control center determines which warehousing facilities are required to respond to the request. The central command and control center then directs one or more warehousing facilities to distribute kits to each site sufficient to collect generated medical waste based on the site information in a distribution step 708.

As the emergency or non-emergency situation unfolds and medical waste is accumulated, the response team forwards containerized medical waste to the indicated disposal facility via a transportation step 710. In certain embodiments, the transportation step 712 includes contacting a courier such as the United States Postage Service, UPS, DHL, FedEx or the like to pick up and deliver the containerized medical waste to the indicated disposal facility.

The system 700 also includes the step of disposing of the containerized medical waste, in a disposal step 714, where the medical waste is disposed of according to guidelines for handling the specific type of medical waste.

Mart Receiver Weight Sensor

A first improvement relates to proper loading of the receiver compartment 204 with appropriate medical waste to be treated and shredded. According to this aspect of the invention, the receiver compartment 204 will be outfitted with one, two or three types of integrated sensors: (i) an integrated pressure transducer or load cell module; (ii) an integrated metal detector; and/or (iii) a radiation detector.

The pressure transducer load cell module provides the system controller with information as to the weight of the medical waste which is placed into the system by the operator at the start of the cycle. The transducer itself may be located immediately below the receiver compartment 204 at 205; under the shredder 208 and motor 210 at 209; or under the entire main unit 102 at 103 so long as the change in weight due to the loaded contents may be accurately determined.

Weight determination offers significant advantages. First, the operator is proactively notified of accidental overload of machine prior to start of automatic cycle. If excessive waste is loaded, the machine will not start the initial cycle, and operators will be provided with an "overload" warning when they attempt to start the automatic cycle. The weight of each machine cycle is also stored in memory and printed by a system printer along with all other parametric data associated with each operational cycle.

The weight of the untreated medical waste is automatically communicated to the system controller to eliminate need for a side-car stand-alone weight scale in markets such as the United Kingdom and Mexico where users of on-site medical waste processors must record starting weight of the untreated medical waste. The weight determination also allows commercial treatment facilities and medical office building installations to track the weight of each machine cycle for immediate billing to specific waste generator clients by the weight of waste loads, and tracking and reporting of waste that was treated by the system for regulatory compliance. The weight determination also ensures that the system will not attempt to treat medical waste which exceeds the maximum weight upon which the system's microbiological efficacy had been validated.

Smart Receiver Metal Detector

The integrated metal detector module 207 provides the system controller with information regarding whether the untreated waste contains too large of a metal object, such as a non-shredable medical implant or surgical tool, which would trigger automatic shredder overload detection during the automatic cycle. This improvement is advantageous since untreated waste is often loaded in "red bags" that do not readily reveal their contents. This sensor system informs the operator prior to the start of the shredding phase of the system that the red bag which has been placed into the treatment vessel contains "too large" of a metal object which has been mistakenly disposed of into the red bag waste steam before they start the automatic cycle.

Smart Receiver Color Detector

As further option, the receiver compartment 204 may also contain an optical sensor 203 to detect the color of the loaded material. Such a feature would, for example, allow red bags of material while rejecting yellow or white containers as these signify dangerous chemicals that should not be added to the system due to certain regulatory restrictions on the treatment of waste which has been color coded by waste category.

Smart Receiver Radiation Detector

As further option, the receiver compartment 204 may also contain a radiation sensor 201 to detect the presence of waste containing radioactive materials, such as oncological waste. Such a feature would, for example, prevent the automatic treatment process from being started by the operator if certain dangerous waste materials that were not intended or approved by regulatory agencies for use in the system were inadvertently loaded into the system.

Smart Receiver Viewing Window

The smart receiver aspect of the invention would also include an integrated viewing window on the receiver compartment 204 and/or loading door 202 which allows both operators and technicians to view the inside of the waste receiver during the actual treatment process. In addition to careful monitoring of the treatment process, this aspect of the invention facilitates technical troubleshooting during machine manual operation, such as back-flush routines to clear a jammed shredder.

Smart Shredder

The smart shredder is a sensor enabled monitor interfaced to the discharge valve 220. The sensor 223 installed in the region of the valve detects whether the shredded waste slurry has sufficient liquid content to ensure that it can flow freely through the system's waste recirculation system. If the sensor detects that the shredded waste slurry has a high solids content, the smart shredder will be commanded to stop shredding, and the slurry will be automatically diluted water and/or disinfectant until the sensor detects that the water-to-solid ratio of the waste approximates a 50:50 ratios to ensure smooth movement of the waste stream through the waste recirculation pump 222.

Smart Discharge

To ensure compliance with certain local sewer ordinances or regulations, software is used to ensure that specific amounts of fresh water are added to the liquid effluent which contains the disinfectant to ensure concentration control during its discharge into the sanitary drain. This aspect of the invention allows the operator to set up and define into the system's controller the required discharge performance of the machine based upon an easy to interpret software setting in parts per million (ppm). Once the required ppm setting for the discharge is entered into the system controller, the machine will discharge the diluted chemical disinfectant automatically to achieve this ppm discharge limit by automatically injecting into the discharge stream the required amount of cold water to dilute the effluent discharge to the ppm set point.

Smart Discharge Air Knife

To ensure that the product in the separator 104 is sufficiently dry, and to comply with certain regulatory limits for the level of free liquids in a solid waste stream, a further aspect of the invention includes a heated or non-heated air knife 230 disposed along the chute 232 of the separator 104 to remove free liquids from the shredded granular material that may otherwise remain due to surface tension. Such Removed Liquid Will Then Flow Back Down The Chute And Out Drain 228.

Communications Capabilities

In accordance with this aspect of the invention, the waste management system is in communication with a central station to send and/or receive compliance data, updates commands or other information. Figure 3A illustrates a stand-alone system in communication with a central station "A." Figure 3B illustrates a multisystem configuration with a partially wired communication link to a central station, and Figure 3C depicts a multi-system configuration with wireless connections to a central station. Although in these drawings communications and other features are represented in conjunction with a "junior" system 302 that is not equipped with a separator unit, the reader will appreciate that all of the capabilities described herein apply equally well to system 102 with separate separator unit 104.

In the configuration of Figure 3A, communication is mediated through computer 306, which may be a separate, conventional piece of equipment or integrated into the system 102 or 302. The configuration of Figure 3B includes an Ethernet hub or USB node 320 which again may communicate with central station "A" through computer 326. While the connections to the hub 320 are assumed to be hard-wired, the rest of the connection(s) may be wired or wireless. The environment of Figure 3C uses a wireless access point 330, whereby all network communications in this case are wireless. In all configurations it may be assumed that station "A" may be in communication with other systems, whether stand-alone or tandem wired/wireless implementations.

A preferred arrangement uses wireless, bidirectional links enabling constant communication with the central station or main office using, for example, a 12-channel cellular communication module. This capability allows the system to communicate in TE - real time with the central office and/or the user's biomedical technical department. The use of a cellular radio channel addresses the need for a hardwire connection to the equipment, and allows for mobile application and placement of equipment in facilities where hardwired installation and/or an Internet connection is problematic. Other communications equipment and protocols, including WiFi, may alternatively be implemented.

The networking allows communications, including information regarding the number of cycles attempted and completed by the equipment, automated billing for pay-per click applications, equipment inhibit by remote control for buy-here pay here equipment financing, automatic consumables re-ordering, equipment performance details and the maintenance status of each piece of equipment. The capability enables proactive dispatch of technicians to improve equipment availability, while providing reliable time stamping of equipment failure events for repair technician performance tracking. Up to 12 key elements of parametric data will be sent using the telecommunications network utilizing both SMS and email messaging, and/or GPRS data using radio packet protocol.

Bi-directional control also allows signals from the central station to control the equipment's key functions such as system reset and system shut down, while allowing customers on pay-per-click equipment acquisition models to report on their daily use of equipment automatically. Bidirectional control features also allow for the equipment to be remotely disabled by the central station operator for equipment users who may have become delinquent in making monthly equipment use payments to the equipment owner; who do not use the approved decontaminating detergent; who use the equipment in an unapproved manner, and so forth.

"E-Regulatory" Compliance

For installations where waste treatment logs are to be maintained, all treatment data may be dispatched wirelessly to each client via the wireless communication system. Daily, weekly, monthly or annual treatment logs may be stored online at a server, and can be e-mailed to each client as a PDF or other appropriate file type, thereby replacing the need for printed paper treatment logs which are generated by the side-car stand alone printer. PC connectivity, as opposed to Internet connectivity, is also available, allowing the unit to send parametric and treatment logs directly to a connected PC in the facility for regulatory reporting.

Routine Preventive Maintenance Reminder Services

In cases where the equipment is covered by a service contract after the end of a warranty period, customers must perform certain routine preventive maintenance. The bi-directional wireless communication capability and interface to the equipment allows for service reminders to be sent to and from the equipment so that maintenance service can be acted upon in a timely manner at the deployed site. Once the equipment maintenance is performed, and a particular service reminder warning is turned off on the equipment, these notices are automatically sent back to the central office where the record of maintenance is maintained electronically to verify compliance with the contract, and to record maintenance for regulatory compliance in markets where service records must be recorded.

Treatment Chemical Compliance

The waste treatment process includes the equipment itself, along with certain registered proprietary chemicals (i.e., SterCid) for use exclusively in the waste treatment devices. In certain overseas markets, the laws of these countries allow for substitution of the disinfectant chemical used in the waste treatment equipment; albeit a violation of warranty and contractual agreements. The use of substitute chemicals in overseas markets is a violation of the approved use of the equipment and results in loss of revenues to the authorized supplier, as the monthly recurring revenue from disinfectant sales is lost. The use of substitute chemicals, either through accidental or intentional use, may also damage certain components of the treatment devices and result in unapproved use of the equipment in accordance with certain regulatory approvals and permits.

To prevent accidental or intentional chemical counterfeiting or usage, a Radio Frequency Identification Device (RFID) or computer-readable code is included with authorized treatment chemical containers. In Figure 3A, a larger container 312, which may feed either systems 102, 302 through a conduit such as line 315, includes an RFID tag 314 which is automatically detected by reader/controller 304. The container 316 may also include a machine-readable code such as a bar code 318 read by a wand 317 interfaced to reader/controller 304. The reader/controller 304 may automatically act upon an unauthorized chemical usage, preventing system operation, for example, and/or the reader/controller 304 may communicate the unauthorized usage to the central station via the communication link(s).

The tag or code may be molded into the cap of the disinfection bottle, or affixed to the outside of the cap of the bottle using a tamper-evident label which will be destroyed when the bottle cap is opened. The appropriate reader is integrated into the system controller, and the controller software requires that the equipment read a valid tag or code from the chemical cap or container in order for the waste treatment process to continue. In this way, use of a chemical substitute without a scanable tag or code will prevent the machine from operating; hence any attempt to use a counterfeit chemical will be prevented.

This ChemLocT" system, integrated into the system controller, ensures that only authentic SterCid disinfecting solutions are utilized in the treatment systems. System operation is blocked unless authentic disinfecting solution is utilized. The ChemLoc includes a unique tag (label) that can be automatically applied to each SterCid unit container at the time of container filling. This aspect of the invention may include a method for accumulation of all tag/label unique codes within a manufacturing (filling operations) batch and replication of this database to portable memory devices such as SanDisk non-volatile flash memory data cards that can be shipped to each customer site with the SterCid disinfecting solution containers. Figure 3 illustrates three different operational options using portable database cards. In Figure 3 A, the card database 310 interfaces directly to reader/controller 304, whereas in Figures 3B, 3C, the database interfaces to the network computer.

The reader/controller system scans the disinfecting solution container tags/codes and authenticates the container as an authentic solution container through comparison of the tag (label) unique code to the SD data card internal database. The result of the comparison is communicated to a system controller comprised of either a personal computer (PC) or an industrial grade programmable logic controller (PLC) using the Internet or other form of connectivity. [0051] To prevent accidental or intentional chemical counterfeiting or usage, a software-only method is also supported. In the software-only embodiment of this feature, the use of an RFID tag is not used. In this software only embodiment, the control system of the equipment includes a large database of read-only multiple digit chemical identification numbers.

These numbers are produced by a random number generator using a certain algorithm that prevents the duplication of these security identification numbers. The database of randomly generated security identification codes is then used to print the same set of numbers onto the disinfectant container labels. The software system requires that the operator enter into the system controller a valid chemical/disinfectant identification number whenever the system requires additional disinfectant.

The system will not operate if the operator enters an invalid chemical identification number into the system controller. The software in the system is designed in such a manner that when an operator enters a chemical identification numbers into the system control keypad, the system control then compares the identification number that was entered by the operator, with the list of pre-registered valid, randomly generated chemical identification numbers. If a valid chemical identification number is entered by the operator, the system will delete this identification number from the system's database of valid identification numbers to prevent reuse of this number in the future. If an invalid chemical identification number is entered, the system will become inhibited; requiring an single use password to be entered by the operator to allow system operation.

While the equipment and method are primarily intended as a process-use specific embodiment and not as a stand-alone general purpose waste shredder/disinfector, special application specific software may be included with the equipment for other unique markets, including the following: Use by a medical waste hauler who collects waste generated by third party facilities and transports this collected waste to a central depot for processing.

Use by a whole blood collection unit operator, who must track each bag of "whole blood" units collected and then track precisely the date, time, and method of destruction of each blood unit which was determined to be unacceptable for redistribution into the global blood supply. [0055] - Use by a mobile-deployed unit, such as a device placed on a moving truck or shipboard naval/cruise ship unit, which requires that the equipment be automatically secured for movement and detection movement as part of the machine's automatic cycle. Use of the equipment in a "common area" of a facility such as a medical office building (MOB) where several users have access to the equipment for waste treatment; much like a photocopier, and use of the equipment by each user/operator must be identified, controlled, restricted, and even automatically recorded by the system to prevent unauthorized use, or the creation of automatic usage invoices, etc.

Enhanced Biodegrade Ability

At the present time, SterCid disinfectant is 94% biodegradable. To increase this value to 100%, additional formulation of liquid-based disinfectants can be used.. One such formulation is stabilized hydrogen peroxide (H 2 0 2 ). Another solution may be added J%02 is acetic acid, which improves the shelf life of the hydrogen peroxide based disinfectant but will also produce an acidic result. One of the problems with externally supplied H 2 0 2 , however, is that it rapidly breaks down and loses its effectiveness. As a further aspect of this invention, the system may include an onboard H 2 0 2 generator 230 utilizing various known or yet-to-be-developed techniques.

As one example, hydrogen peroxide may be generated using an electrochemical cell having a gas diffusion electrode as the cathode (electrode connected to the negative pole of the power supply) and a platinized titanium anode. The cathode and anode compartments are separated by a readily available cation- exchange membrane (i.e., Nafion@ 1 17). The anode compartment is fed with deionized water. Generation of oxygen is the anode reaction. Protons from the anode compartment are transferred across the cation-exchange membrane to the cathode compartment by electrostatic attraction towards the negatively charged electrode. The cathode compartment is fed with oxygen, and hydrogen peroxide is generated by the reduction of the oxygen. Water may also be generated in the cathode. A small amount of water is also transported across the membrane along with hydrated protons transported across the membrane. Generally, each proton is hydrated with 3-5 molecules. The output is hydrogen peroxide as a high-purity aqueous solution may be added to the SterCid disinfectant mixture or replace SterCid as desired.
