A system for treating infectious waste is provided that employs a medical waste handling and shredding sub-system that feeds partially processed waste to an oxidizer to eliminate potential airborne infectious waste prior to transforming the medical waste into useful co-products. Medical waste is transformed into value added products including hydrocarbon based gases, hydrocarbon-based liquids, carbonized material, and recovered precious metals and rare earth materials in a system having as its transformative element an anerobic, negative pressure, or carbonization system. With medical waste as a feedstock for the production of valuable products, an economically viable and environmentally more responsible alternative to traditional methods of medical waste treatment is realized.

The present invention relates to a method for gasification of carbon-containing materials including biohazard wastes, and more specifically, to a method for gasification of carbon-containing materials which allows an increase in carbon efficiency and a reduction in carbon dioxide emission, comprising the steps of: biohazard wastes grinding and sterilization, mix with carbon-containing materials for the gasification; and catalytic production of diesel fuel. A system having a movable platform including: material preparation block, gasification and catalytic of diesel fuel production reactors which are structurally and functionally integrated. In the practice of the process, a mixture of carbon-containing materials, a compressed air feed and process steam is fed to the gasifier to produce a synthesis gas. The synthesis gas is fed to the Fischer-Tropsch reactor where it is catalytically reacted to produce heavy hydrocarbons. The outlet from the Fischer-Tropsch reactor is separated into water, a low heating value tail gas, and the desired hydrocarbon liquid product. The water is pressurized and heated to generate process steam. The system further includes a plurality of heat exchangers that enable heat to be recovered from the outlet of the gasifier. The recovered heat is used to make the process steam as well as to preheat the hydrocarbon mix before it is fed to the gasifier and preheat the synthesis gas before it is fed to the Fischer-Tropsch reactor. The method of the present invention greatly increases carbon efficiency and reduces the generation of carbon dioxide.

Provided is a method for treating a used absorbent article, this method being hygienic and capable of recovering recyclable material with a high degree of safety. This method for treating a used absorbent article is characterized by including (a) an acidic electrolyzed water treatment step that treats the used absorbent article in a treatment tank that has acidic electrolyzed water serve as a treatment fluid. This method preferably further includes (b) an alkaline electrolyzed water treatment step that treats the used absorbent article in a treatment tank that has alkaline electrolyzed water as a treatment fluid.

The present disclosure is directed to a treatment system for medical and toxic waste. The system comprises two parts, a heterogeneous gasification system, in which syngas is produced from non-homogeneous waste, and a pyrolysis system, in which medical and hazardous waste are pyrolyzed using the syngas produced from the heterogeneous gasification system. The heterogeneous gasification system comprises a gasifier reactor having a reactor zone connected with an ash distillation zone, a re-fueling structure, an open-top water tank that wraps around the entire bottom section of the gasification system, and a gasification-agent supply module having a supply-end connected to the bottom of the gasifier reactor and a demand-end connected to the pyrolysis system. The pyrolysis system comprises a rotatable pyrolysis reactor having a horizontal and hollow cylindrical shape, a pyrolyzed-ash precipitator, which is connected to the pyrolysis reactor zone, and a condenser connected to the pyrolyzed-ash precipitator.

Exemplary compositions, methods, systems, and kits are disclosed that render excess pharmaceuticals safe by chemically transforming the active pharmaceutical ingredient into an environmentally benign and biologically inert form. The methods and kits have additional advantages of convenience, low cost, long shelf life, and ease of handling.

Improvements in a processing basket lining system for slide maker-stainer instrument. The utility liner is configured to sit on top of the processing baskets that are customarily occupied/filled with the processing reagents. The probe jackets are shaped to slip in and out without interfere with its capacity to dispense-drain reagents while submerged to the intended reagents in the processing baskets. The liners provide a surface between the processing baskets or probes and the reagents where debris can accumulate as a waste by-product of the process largely in quantities or simply just by the length of use time. The disposable utility lining system, processing basket and probe cover are disposable. The liners are preferably made of plastics. The material of choice is tested not to react with the processing reagent for a period of time, depending on the manufacturer's maintenance requirement.

Efficient and adequate disposal of medical infectious waste is proportional to the reduction of the spread of infectious diseases and the disease itself among humans. The essence of this invention is that infectious medical waste is in a timely, fast, efficient, simple, and environmentally friendly safely disposed of and turned into inert-municipal waste. Previous methods and devices for the disposal of infectious medical waste involved long-term procedures for the collection, sorting and storage of infectious medical waste, which increases the risk of secondary infections. This invention skips the process of collecting, sorting and storing medical infectious waste, and the entire process in the invention takes place in three unbreakable phases whose end product is municipal-inert waste. It is important to emphasize that with this invention, even the smallest amount of infectious medical waste will be disposed of immediately in an appropriate manner. And as a result, a maximum control over all medical infectious waste is achieved.

The present invention comprises a method of shredding treated medical waste, cleaning it of all traces of biological gunk, and sorting it into separate components for recycling. To clean biological gunk from materials, all materials must be first shredded into small parts to expose the interior. The cleaning is performed by submerging the gunk coated materials into a caustic solution that breaks down and dissolves the gunk off of the materials. The caustic solution may comprise sodium hydroxide, potassium hydroxide, or a similar chemical, which is highly effective in producing a corrosive chemical that can break down blood, bone marrow, urine, unused medication, food waste, organs, tissues and any other biologic materials. After all of the biological material is removed from the cleaned materials, they are sorted into component materials, such as plastics, metals, rubbers, glass, etc.

Systems and methods for rendering cannabis-related waste materials are provided. The method may include inserting a plurality of cannabis-related waste materials into, for example, a mobile rendering vehicle. The method may further include physically altering the cannabis-related waste materials such that the cannabis-related waste materials are unrecognizable and unusable. The insertion of the cannabis-related waste materials into the mobile rendering vehicle may be recorded and/or the physical alteration (e.g., pulverization) of the cannabis-related waste materials may be recorded via one or more cameras disposed on the mobile rendering vehicle to verify proper insertion and/or alteration of the cannabis-related waste materials.

The present invention addresses the problem of efficiently manufacturing a recycled pulp from a used sanitary article, said recycled pulp being reusable for sanitary articles and having an ash content and antibacterial properties both meeting the standards for sanitary articles. A method for manufacturing a recycled pulp reusable for sanitary articles by recovering a pulp fiber from a used sanitary article that contains the pulp fiber and a high water-absorbing polymer, said method comprising an ozone treatment step for immersing the used sanitary article or pulp fiber in an ozone-containing aqueous solution and thus disintegrating the high water-absorbing polymer contained in the used sanitary article or sticking to the pulp fiber, characterized in that the used sanitary article or pulp fiber is treated with a cationic antibacterial agent before, after or together with the ozone treatment step.
