    摘要: A process of phytoremediation is provided in which the above-ground surface is first amended with stabilizing additives which will react with and bind subsurface contaminants. As the contaminants are brought to the surface through the growth of phytoextracting plants, the plants' vegetation is left to die in situ. As the plant biomass decomposes, the soil contaminants brought to the surface react with and/or are bound by the soil amendments. The soil amendments may further be provided in the form of a geotextile barrier or mat having one or more additive layers present within the mat structure.

    摘要: A process and resulting product is provided in which a solid particulate, such as vulcanized crumb rubber, has the surface functional groups oxidized by ozonation using a nonpolar solvent. The ozonation process renders the treated crumb rubber more suitable for use in new rubber formulations. As a result, larger loading levels of the treated crumb rubber can be used in new rubber mixtures.
