Abstract
An oil absorbing material is generally provided. The oil absorbing material can includes sorbent particles having an average aspect ratio of about 5 to about 500 and a mean average particle diameter of about 10 μm to about 1 millimeter. The oil absorbing material comprises polypropylene, polyethylene, inorganic filler particles, and absorbent core material. In one embodiment, the sorbent particles can have an average specific surface area of about 0.25 to about 5.0 m/g and can have a bulk density that is about 0.01 g/cmto about 0.8 g/cm. Processes of making the oil absorbing material are also provided via a solid-state shear pulverization recycling process transforming absorbent article waste into the oil absorbing material. The process can include pulverizing the absorbent article waste to form sorbent particles while cooling the absorbent article waste in an amount sufficient to maintain the absorbent article waste in a solid state.
