A preliminary test of Fibertect on the soiled beaches of Grand Isle, La., has proven it successful at picking up the oily paste washing ashore at beaches and marshes across the Gulf State region.

Seshadri Ramkumar, an associate professor of nonwoven technologies, said the Texas Tech-created nonwoven cotton absorbent wipe with activated carbon core makes it a perfect remediation tool for use by cleaning crews trying to remove the toxic material.

Not only did it clean up the rust-colored crude oil, but also it adsorbed toxic polycyclic aromatic hydrocarbon vapors reportedly sickening oil spill clean-up crew members.

Ramkumar said his latest research shows raw cotton-carbon Fibertect can absorb oil up to 15 times its weight. Unlike synthetic materials like polypropylene that are currently used in many oil containment booms, Fibertect is made from environmentally friendly raw cotton and carbon.

Amit Kapoor is president of First Line Technology, which distributes Fibertect commercially. Though the product has been tested in the lab with raw crude and motor oil, he said the company wanted to field-test the product.The product is manufactured by Hobbs Bonded Fibers, Waco, USA.

Earlier this week, he sent a sales representative, who also works as an independent contractor for BP, to one of the worst-hit areas.

Though Kapoor said he had seen Fibertect pick up similar material with a pasty consistency, such as petroleum jelly, the results shocked the sales representative sent to run the experiment.

Fibertect was approved for use as a sorbent by the U.S. Environmental Protection Agency, Ramkumar said.The product already has proven that it can also adsorb toxic fumes associated with chemical remediation, he said. Evaluation by Lawrence Livermore National Laboratory found that it can retain offgassing mustard vapors efficiently and does not shed loose particles.

Originally developed to protect the U.S. military from chemical and biological warfare agents, Fibertect contains a fibrous activated carbon center that is sandwiched between layers.

The top and bottom layers, made from raw cotton, can absorb oil while the center layer holds volatile compounds such as the polycyclic aromatic hydrocarbons, or blistering agents such as mustard vapors or other toxic chemicals.
