New Method for Cleaning Up Land-Based Oil Spills Shows Promise


 
May 22, 2015 – Researchers at Hebrew University of Jerusalem have developed a product that oxidizes soil polluted by oil and other contaminants. According to an article appearing in the May 22, 2015 edition of Haaretz, one of Israel’s leading daily newspapers, the product, known as NHS+ reagent, was developed at the Casali Institute of Applied Chemistry. The product can be used at the site of a spill and within a few hours turns oil in the soil into carbon dioxide and water. Its inventors, Professor Yoel Sasson and Dr. Uri Stoin, refer to it as a hydrocarbon destructor that works on oil or solvent spills.
The technology went from the laboratory at Hebrew University to Yissum Research and Development, a technology transfer company the university set up in 1964. Yissum handles more than 8,900 patents, 2,500 inventions and has licensed 800 different products and processes globally. This has spawned 90 different companies which generate more than $2 billion U.S. in annual sales. The range of technologies coming out of Hebrew University that Yissum has commercialized cover agriculture and food, chemistry and materials science, clean up and environmental technologies, computer science and engineering, life sciences, biotechnology, veterinary and animal sciences.
In the case of  NHS+ reagent, it has been sold to the Man Oil Group, a Swiss company. In December 2014 they conducted a desert pilot at an Israeli landfill site containing contaminated soils. The process of application took approximately two hours and within a few hours after the reagent had converted 80 to 90% of the hydrocarbon contaminants to carbon dioxide and water.  MORE
