Scientists at Ohio’s College of Wooster chemistry department have stumbled upon a way of cleaning the water ‘produced’ from oil and gas extraction.
As much as 800 billion gallons of water is ‘created’ this way each year, but is generally unusable because of its toxicity. Now, though, a development in nano-engineering means that tiny glass ‘sponges’, known as Osorb, can remove more than 99 percent of oil and grease from water, and more than 90 percent of the volatile compounds that can poison drinking water.
The material absorbs small organic toxins whilst repelling water, and can be reused over 100 times after the chemical nasties have been removed. See it at work here:
