In response to a growing societal mandate, land disposal of hazardous wastes is gradually being replaced by treatment technologies. This shift to “alternative technologies” is the result of the impacts of past land disposd practices on other environmental media (groundwater, surface water, and air). A prime motivation for pdopting alternatives to land disposal is to eliminate these cross-media ...

The Regional Ground Water Forum is a group of ground-water technical specialists, representing EPA's Regional Offices, organized to exchange up-to-date information related to groundwater remediation at hazardous waste sites. Proper site characterization has been identified by the EPA Regional Ground Water Forum as a major issue of concern for decision-makers at many hazardous waste sites. In or...

Hazardous waste management involves the collection, transportation, treatment and disposal of hazardous wastes. In this paper a new multiobjective location-routing model is proposed. Our model also includes some constraints, which were observed in the literature but were not incorporated into previous models. The aim of the proposed model is to answer the following questions: where to open trea...

The efficient large-scale recycling of plastic waste is of increasing interest from an ecological and economic point of view but it represents a goal that has yet to be achieved by the recycling industry. The W2Plastics project aims at a fundamental change of the present status of plastics recycling by creating a breakthrough technology for the recycling of polyolefin’s from complex wastes, i.e...

In this study, ferrochromium slag (FS) and electric-arc furnace dust (EAFD) samples were examined for their hazardous hexavalent chromium content mainly by X-ray photoelectron spectroscopy (XPS) analysis. According to the experimental results, magnesium-silicate constitutes main framework of both FS EAFD samples. Highly crystalline contains 3.11%Cr2O3 as spinel phases while constituent is much ...
