An apparatus and method for endwise connecting subterranean barrier members is disclosed. The apparatus includes at least two barrier members with each barrier member extending between top and bottom edges. Further, each barrier member has a side first edge having a flange defining a first connector and an opposed second side edge having a channel defining a second connector. The channel is sized and shaped to receive the flange of an adjacent barrier member in slidable interconnection therein. The apparatus further include a first side panel shaped to lie against a first side of the barrier members, a second side panel shaped to lie against a second side of the barrier members and a bridging plate located between the first and second panel members so as to bridge a gap therebetween, wherein the gap has a width corresponding to a width of the first and second barrier members. The associated method is directed toward creating the apparatus.

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.

Methods and systems for inhibiting biodegradation of biodegradable organic material are provided. In particular, methods for the treatment and storage of organic material (e.g. waste, vegetation) in hypersaline environment, including mixing with oceanwater, concentration to hypersalinity and maintenance of carbonaceous organic waste in the hypersaline environment, rather than combustion or decay thereofare provided.

A machine for shredding inorganic waste is described, comprising: first loading means; a shredding chamber; second shredding means; third unloading means; fourth electronic control means; fifth means for limiting the resisting torque applied to the motor, in such a way as to avoid current absorption that exceeds the capacity of the power supply network, said fifth means comprising one or more mobile elementsand a plurality of blades. A method for operating the machine is also described.

A method of carbon and nitrogen sequestration includes excavating a ditch around a plot of land selected for use in carbon and nitrogen sequestration. Pumping out water filling the ditch from the ground water table. When material in the plot is dry, excavating material from the plot to a desired depth, and thereafter filling the excavated plot with organic material to sequester carbon and nitrogen in the organic material therein.

This disclosure relates to a method and a system for sequestering carbon-containing materials in underground wells. An example method includes: obtaining a material comprising a carbon-containing liquid; optionally testing the material for compatibility with an underground well; optionally adjusting a property of the material to improve the compatibility; and providing the material for injection into the underground well.

The present invention relates to a method for degrading and inactivating at least one xenobiotic, the at least one xenobiotic being present in an aqueous medium. The method comprises the steps of (a) grafting at least one enzyme onto a solid support, (b) incubating the solid support with the at least one enzyme into the aqueous medium and (c) measuring the evolution of the concentration of the at least one xenobiotic. The method is remarkable in that the at least one enzyme is New-Dehli metallo-β-lactamase 1, a laccase extracted from Pleurotus ostreatus and/or a β-lactamase extracted from Pseudomonas aeruginosa and in that the solid support is a moving bed carrier.

A polyethylene terephthalate purification apparatus comprises at least a reactor (4) which houses the plastic material to be purified, an opening connected to a vacuum pump, stirrers (16) to ensure the stirring of the plastic material inside of the reactor (4) and a heating mechanism comprising a microwave heating device to promote the excitation of the polar molecules.

Provided is a method that, when pulp fibers are recovered from used absorbent articles that have been put into collection bags, makes it possible to safely and sanitarily crush the used absorbent articles while suppressing costs. A method for recovering pulp fibers from used absorbent articles, the method comprising: a crushing step (S12) in which collection bags (A) in which used absorbent articles have been sealed are put into a container (65), the collection bags in the container are transferred to a crushing device (12) that communicates with the container, and, bag by bag, the crushing device crushes the used absorbent articles in the collections bags in a deactivating aqueous solution; and a separation step (S13) in which the pulp fibers, a highly water-absorbent polymer, and the deactivating aqueous solution are separated from the crushed product and deactivating aqueous solution obtained in the crushing step.

A method and system for training a machine learning model configured to perform characterization of components in a material stream with a plurality of unknown components. A training reward associated with each unknown component within the plurality of unknown components in the material stream is determined, based on which at least one unknown component is physically isolated from the material stream by means of a separator unit, wherein the separator unit is configured to move the selected unknown component to a separate accessible compartment. The isolated at least one unknown component is analyzed for determining the ground truth label thereof, wherein the determined ground truth is used for training an incremental version of the machine learning model.
