Abstract:
1. A method of manufacturing an oil product sorbing and/or filtering material, comprising: adding a modifier to vulcanized rubber waste in a proportion of between approximately one and a half pounds to approximately two and a half pounds for each 100 pounds of vulcanized rubber waste, the modifier comprising a mixture in the following proportions by weight (i) a slightly water-soluble organic acid having a melting point of 70 degrees Centigrade or higher representing between approximately 70 percent and approximately 90 percent of the mixture, (ii) quinine group bases representing between approximately 9 and approximately 29 percent of the mixture and (iii) either a terpene or colophony, representing between approximately three quarters and approximately 1 and a quarter percent of the mixture, to obtain a mixture of rubber crumb and modifier, crushing the mixture of rubber waste and modifier to create crushed modified rubber particles, and converting the crushed modified rubber particles into porous agglomerations of modified rubber.
