| As BP struggles to contain the oil spill in the Gulf of Mexico, an Indian-origin scientist from Texas University has created a special cotton fabric that can clean up crude oil up to 40 times its weight and help in cleaning efforts.
Seshadri Ramkumar, Associate Professor of the Texas Tech Institute of Environmental and Human Health, has created a non-woven environment-friendly cotton carbon absorbent wipes, Fibertect.
"Cotton fibre contains 0.5 per cent wax, which enables it to soak up 40 times its weight," Ramkumar said.
"The chemistry of cotton makes it the ideal material for oil absorption with its waxiness, strength when wet, absorption capacity and ability to biodegrade," explained Professor Ramkumar, who described his discovery as "a blessing in an ironic situation."
"The synthetic booms soak up only a third of what cotton absorbs and are not biodegradable. You take those plastics and where do you put them? In landfills. They will stay put forever," he added.
"Add chemicals and it could absorb up to 70 times its weight," he said.
Through his research with nonwoven cotton, Ramkumar may have found an all-natural way to absorb oil from spills.
Rather than spending money and effort on containment structures and synthetic materials, he recommends utilizing cotton.
Ramkumar is surprised that why cotton had not been considered earlier, reported the A-J's Alyssa Dizon.
"We are the only ones...to my knowledge...focused on taking cotton to oil absorption using nonwoven technology," he said.
