| 摘要 |
A plurality of water- and oil-porous sacks (10) are partially filled with a number of generally tubular macroscopic bodies (300) of a polymer material that entraps oil, including preferably styrene-butadiene-styrene and ethylene propylene diene monomer. The bodies (300) can be generally cylindrical with an axial hole and a length greater than the diameter, so that when afloat in water, such as in sacks (10), the axial hole parallels to the water surface. The bodies (300) are preferably formed from granular material in a novel lowtemperature extrusion process that links substantially unmelted SBS granules (380) in an EPDM matrix (390). When so formed, the bodies (300) have numerous fissures (370) extending from the surfaces, yet retain structural integrity without flaking or crumbling. Novel sack structure, sack deployment, sack retrieval, and material disposition systems, including in situ burning, are also disclosed. |
