Description:
Many contaminants of concern at hazardous waste sites are difficult to treat because of their chemical and physical characteristics. Constituents which have low vapor pressure, low water solubility, and low potential for biodegradability are not candidates for many technologies. Metals are a prime example as are polychlorinated biphenyls (PCBs). The proposed technology is a cold mix asphalt emulsion process which is based upon a proprietary process successfully being used for the remediation of sites containing petroleum products. Not only will this process target mixed wastes of metals and organic compounds in soils, but this process also has the added benefit of being able to incorporate contaminated building rubble as part of the asphalt aggregate system. The materials thus produced can be used in various applications including road paving, parking lots, capping landfills, etc. Supplemental Keywords:Toxics, Water, Sustainable Industry/Business, Scientific Discipline, Waste, Remediation, Technology for Sustainable Environment, Chemistry, cleaner production/pollution prevention, Contaminated Sediments, Hazardous, New/Innovative technologies, National Recommended Water Quality, 33/50, Engineering, soils, treatment, paving products, Polychlorinated Biphenyls PCBs:, soil and groundwater remediation, contaminated waste sites, lead, cold mix asphalt emulsion process, hazardous waste sites, lead & lead compounds, hazardous waste disposal, metals, contaminated soil, hazardous waste, hazardous waste site, hazardous waste treatment, innovative technology, organic contaminants, soil, PCB
