Abstract: Drain sleeve retention and release assembly embodiments having a pivotable bar rotatably attached to a water tank frame and a releasable attachment mechanism attached to the frame, wherein the releasable attachment mechanism is movable between a deployed position a retracted position, wherein a flexible drain sleeve is positionable between the pivotable bar and the top rail such that the flexible drain sleeve is releasably clamped between the pivotable bar and the frame when the releasable attachment mechanism is disposed in the deployed position.

Abstract: A recycling and waste management process receives municipal solid waste (MSW) with substantial organic content to form a self-sustaining Hydrothermal Mineralization (HTM) process based on Supercritical Water Oxidation (SCWO) to receive supercritical steam and carbon dioxide with potential for electrical generation before forming calcium carbonate suitable for concrete production. Hydrothermal mineralization (HTM) provides a rapid elimination of organic wastes while simultaneously producing a non-emissive and thermally stable cement additive to act as a carbon sink. Hydrothermal mineralization (HTM) provides a rapid disposal pathway for organic wastes, a green source of electricity and a final product that can be coupled with traditional and alternative cement productions to reduce carbon footprints of cement production.
