“Super Sponge” Polymer to Mop Up Oil Spills Created

Something for certain communities to think about using when they inevitably suffer effects of an oil spill, as there are still way too many oil pipelines around the world. It really is stupid for them to still exist at such scale — in the U.S., Keystone XL unfortunately was approved, and in Canada Trudeau keeps campaigning for the oil pipelines, disillusioning a lot of Canadians in the process.

Oil spills could be soaked up by a new floating substance that combines waste from the petroleum industry and cooking oil, according to new research led by South Australia’s Flinders University.

The new polymer, made from sulphur and canola cooking oil, acted like a sponge to remove crude oil and diesel from seawater, according to a new study published in the Advanced Sustainable Systems journal. The polymer can be squeezed to remove the oil and then reused.

The lead researcher, Dr Justin Chalker, said it had the potential to be a cheap and sustainable recovery tool in areas affected by oil spills.

“We anticipate that when we get to economies of scale we will be able to compete in price with other materials that are used to soak up oil,” said Chalker, senior lecturer in synthetic chemistry at Flinders University.

“Our goal is for this to be used globally. It is inexpensive, and we have an eye for it to be used in parts of the world such as the Amazon Basin in Ecuador and the Niger Delta that don’t have access to solutions to oil spills.”

The International Tanker Owners Pollution Federation says about 7,000 tonnes of crude oil were spilt into oceans last year.

The Flinders University research is just six months ago but Chalker said the new polymer had the potential to be less expensive and more sustainable than current clean-up tools such as polypropylene fibres and polyurethane foam.
