ABSTRACT:
A device for collection and containment of spilled or leaked liquid hydrocarbons absorbs pollutants that come in contact. The absorbed material is solidified-within the pillow into a rubber-like mass. An impermeable layer-of material may be utilized in forming the bottom layer of the outer envelope of the device to retain accumulated hydrocarbons-within the pillow while further allowing the contaminants to disperse throughout the device for absorption and solidification. The impermeable layer prevents spilled or leaked hydrocarbons from contaminating the surface below the device. The consolidated mass is easily retrieved and handled for disposal. A variety of options may be utilized in disposing of the spent device, including recycling the rubber-like mass as a component of tar-like materials, such as asphalt. The solidified hydrocarbons will not leech when exposed to pressure limits used to determine landfill suitability.
