'super sponge' seen as absorbent next step in oil spill mitigation - oil spill absorbent materials
Engineers at the University of Calgary say they have come up with a new and effective new technology as they look globally for better ways to clean up oil spills.
This process uses a material that they call a "super sponge. "It's non-
Toxic and biodegradable at startup.
To prove this, Nashaat Nassar divides asphalt into two types
A glass container filled with water, then flick the switch.
The mixture is shaken and stirred.
Then, the chemical engineer and Associate Professor sprinkle a dark powder on it --
A compound of boron and nitrogen.

7 m federal refund for the North Gate pipeline project "they are drain.
So they don't like water.
They like oil, "said Nasser.
On a microscopic level, the material is very porous, a bit like a sponge, and saysNassar shows this by suspending the magnet wrapped on the foil on the oil and putting it
"With this material, we can minimize the spread of oil," he said . ".
There are also "sponges"
Production is toxic and cheap, Nassar said.
The innovation project is part of a new field of oil spill cleanup research.
Similar research in the United StatesS.
Scientists at the Argonne National Laboratory outside Chicago are working on another sponge solution.
They use specially treated polyurethane foam to absorb oil.
"You can pick it up and squeeze it like a kitchen sponge and the oil will come out," said laboratory scientist Seth Darling . ".
"We went there and it was very clear that you could pick up the oil slick deployed from the ship from the surface of the real world ocean.

Prompting many scientists to rethink clean-up technology.
"Everyone sees its disastrous impact on the environment and the monetary burden it has on companies and the local economy as a whole.
So, many researchers believe that there must be a better way to deal with this problem than outside.
Many people began to study the problem.
"Normally, oil spill cleanup involves slightly crossing and burning crude oil from the surface of the water, or breaking it down with a chemical cleaner.
But a scientific historian at King's College Halifax says the oil recovery rate is far from perfect.
"No one will question that our record is not very good," said Ian Stewart . ".
"It's a very, very complex, very challenging thing.
He said: "The size and location of the leak is also a factor in recovery.
Five to fifteen minutes per centimeter.
But it depends.
If you have the right technology at hand in a very calm, secluded bay, then you can restore more technology. It does vary.
The major leaks that have occurred in history usually occur where it is difficult to recover.
"But he warned that real-world testing of the new clean-up technology is another challenge.
When switching hands across mountains, cold water couples are not sure who will clean up the lingering oil spill "it's all promising.
As these researchers are going to tell you, the problem is that they are far from the operation.
"Back at the University of Calgary, the researchers recognized that lab presentations were one thing.
The open ocean is another.
"We have been working hard to find effective technologies that go beyond labs and try to find more realistic solutions to the problems facing the industry today," Nassar said . ".
The next step, he said, is to test the "super sponge" on a larger scale ".
