Abstract: An AHP is disclosed having a topsheet, a backsheet joined with the topsheet, an absorbent core, disposed between the topsheet and the backsheet, and a poly(acrylic acid)-based superabsorbent polymer (SAP), partly derived from recycled resources. The SAP exhibits defined Saline Flow Conductivity and Absorption Against Pressure values. Methods for making the aforementioned AHP are also disclosed.

Abstract: Used AHP or its components is converted into a stream comprising low molecular weight n-paraffins, iso-paraffins, naphthenes, olefins, and aromatics using an HTT reactor. These low molecular weight hydrocarbons produce ethylene, propylene, and other chemicals when fed into a steam cracker, which can be used to produce polyethylene, polypropylene, and SAP recycled components of the AHP or a fully recycled AHP.

Abstract: A method for purifying a contaminated reclaimed HDPE is provided. The method comprises obtaining the contaminated reclaimed HDPE, extracting it with a solvent to produce an extracted contaminated reclaimed HDPE, and then dissolving it in the solvent to produce a first suspension comprising dissolved HDPE and suspended contaminants. The first suspension is settled to produce a second suspension comprising dissolved HDPE and suspended remaining contaminants, and the second suspension is purified by contacting it with solid media to produce a third suspension comprising purer HDPE. Finally, the purer HDPE is separated from the third suspension and it has natural-like optical properties.
