    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 m2/g and can have a bulk density that is about 0.01 g/cm3 to about 0.8 g/cm3.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.

    Abstract: An adsorbent composition and method of cleaning the industrial waste water using the composite is described. The method for removing heavy metals from contaminated water is done by mixing contaminated water having a concentration of one or more heavy metals with an adsorbent composite comprising granules of a mixture of 50.363 wt % kaolin clay, a 4.477 wt % roasted date pits powder, a 5.54 wt % silica powder a 14.99 wt % magnesite powder and a 24.623 wt % water. After reacting the contaminated water and adsorbent composite together for a specific time the water is filtered and was found to contain reduced amount of heavy metals. The cleaned water can further be used for industrial cooling systems or watering gardens.
