20140284513 | Oil Reclamation Mixture - An oil reclamation mixture consisting of an activating compound, mechanical coagulant and co-factors. Oil spills and their resultant contamination of life is an ongoing threat that affects the entire bio-ecosystem (marine and terrestrial, alike) and to financial markets. By using a mixture of natural ingredients and chemical principles, the threats to ecosystems are mitigated. Traditionally Oil Dispersants have been used to spread out the contamination, however, in our mixture utilizes non-toxic off the shelf ingredients to provide a product that induces free oil floating on the surface of water to coagulate and form aggregate clumps for easy of skimming off the surface in a clean up operation. Because less toxic materials are used, inhabitants and marine life of the affected area are less impacted financially and physically. The oil can also be reclaimed and recycled out of the recovered materials that are skimmed. Because no toxic materials are used to lock up and coagulate the oil material, this process is seen as new and unique. | 09-25-2014 |
