A water stream containing hardness minerals is subjected to a water treatment process using an alkali agent to precipitate the hardness minerals and to produce a softened water stream is used to create an integrated water treatment and flue gas desulfurization process. Thereafter, the softened, alkaline water stream is utilized in a scrubber to scrub a flue gas containing sulfur dioxide to produce a sulfur-lean flue gas. The invention may be applied to a steam-based bitumen recovery operation where bitumen, sour produced gas or other sulfur containing fuels are burned for producing steam for bitumen recovery. More specifically, the associated produced water from the bitumen recovery process may be softened for re-use and for utilization as a scrubbing agent for high-sulfur containing flue gas arising from the steam generators. The process provides an economically favorable process while minimizing waste disposal requirements.

An integrated cutting system for a waste disposal device comprising a waste storage receptacle and a film cutting and sealing device. A cartridge containing a continuous length of film is positioned over the receptacle. The integrated cutting system further includes an activation mechanism operatively configured to alternatively engage a cutting device or a film sealing device capable of twistably sealing the film of the cartridge when the film is dispensed from the cartridge. A selection mechanism is arranged to control the activation mechanism to either engage the cutting device while deactivating the film sealing device, or to engage the film sealing device while deactivating the cutting device. The cutting device comprises a blade positioned to sever the film from the cartridge.

The present invention is related to methods and systems for waste disposal and information distribution. A discard information processing apparatus comprises a discard unit including a processor, a scanner, the scanner configured to scan a code on items deposited in the discard unit, a network interface coupled to the processor and configured to communicate over a network, a database storing information related to the discard unit's contents, and a profile associated with a user of the discard unit. A remote processing system is coupled to the discard unit via the network, the remote processing system including instructions configured to receive information from the database, wherein the received information provides an indication as to when at least a first item is to be replenished, and to provide at least a portion of the received information to at least a first supplier so that the first supplier can predict inventory needs.

The invention discloses a waste disposal apparatus including a waste packet forming device integrated with a tool for cutting the packet, and a method for using the apparatus. The disclosed integrated twist-and-cut system provides an improvement over existing waste disposal systems by reducing steps in the disposal of waste material.

A method and apparatus for plasma waste disposal of hazardous waste material, where the hazardous material is volatilized under vacuum inside a containment chamber to produce a pre-processed gas as input to a plasma furnace including a plasma-forming region in which a plasma-forming magnetic field is produced. The pre-processed gas is passed at low pressure and without circumvention through the plasma-forming region and is directly energized to an inductively coupled plasma state such that hazardous waste reactants included in the pre-processed gas are completely dissociated in transit through the plasma-forming region. Preferably, the plasma-forming region is shaped as a vacuum annulus and is dimensioned such that there is no bypass by which hazardous waste reactants in the pre-processed gas can circumvent the plasma-forming region. The plasma furnace is powered by a high frequency power supply outputting power at a fundamental frequency. The power supply contains parasitic power dissipation mechanisms to prevent non-fundamental, parasitic frequencies from destabilizing the fundamental frequency output power. These power loss mechanisms use either distributed resistance or frequency-selective power-loss devices to prevent parasitic oscillations from instantaneously turning on the high frequency power oscillator at non-fundamental frequencies.

A waste disposal device comprises a container having a lid. An externally accessible actuation mechanism comprising a rack and a pinion is connected to the lid, and is operatively configured to interface with a foot pedal. When the actuation mechanism is actuated by pressing the foot pedal, the lid opens, while the rack skips over the pinion. When the foot pedal is released, the rack engages the pinion, which in turn closes the lid and spins a cartridge of the device one revolution.

A waste disposal device comprises a container having hamper. The hamper is insertable and removable through a movable door of the container.

A system and method for tracking supplies, particularly medical supplies, and specifically individual medical items, to the end of the product lifecycle to the point of utilizes. RFID tag technology is utilized. This has the advantage of enabling a system that requires less or no active intervention by the medical services delivery staff, such as nurses and doctors. Nonetheless, the system is applicable to other stand-off identification systems including taggant-based systems. The system provides for the monitoring of items, such as medical items, between the distribution center, facility stock rooms and inventory cabinets, and the procedure rooms in which the items are put into use. In one example, system and method associate stand-off, such as RFID, readers with waste-disposal or refuse containers and / or readers located near the point of usage, such as in or associated with the procedure rooms in order to monitor the endpoint of the product lifecycle. Thus, the knowledge of medical item disposal or disposal of the medical item's packaging is combined with one or more prior detections of the medical item, e.g., at acquisition and when moved to a different location such as storage, to generate a usage history for the item. In all or more cases, this knowledge is acquired with out human intervention by judicious location of readers at the distribution center and / or medical facility.

A waste disposal device including a cartridge movable by rollers. The waste disposal device comprises a rotation mechanism for rotating the rotatable cartridge. The cylindrically shaped waste disposal device has an inner wall. The rotatable cartridge comprises a cylindrical shape having an outside wall. The rotation mechanism comprising at least two opposingly aligned movable rollers extends between said inner wall of said waste disposal device and said outer wall of said rotatable cartridge. The rollers are engagingly configured to cause the cartridge to rotate upon activation of the rotation mechanism.

Disposable paper eating utensil enabling most of the utensil-constituent paper to be recycled. A blank composed of at least one thin ply laminated onto a thick ply is inserted between the core and cavity of a compression mold and molded into the utensil. The molding process clenches corrugations produced in the thin ply into corrugated portions of the thick ply, produced in the rising sidewall surfaces of the utensil, yielding a paper eating utensil of not readily separable two-ply construction. The eating utensil thus obtained can contain foodstuffs bearing liquid condiments, and after the utensil has been used the thin ply can be separated from the thick ply and disposed of as soiled waste, while the thick ply portion discarded as recyclable waste.
