Scrap material recovery and recycling companies are confronted with waste water that has a highly fluctuating flow rate and composition, containing pollutants, such as COD, nutrients and suspended solids; potentially toxic metals, polyaromatic hydrocarbons and poly chlorinated biphenyls can exceed the discharge limits. An analysis of the leaching behaviour of different scrap materials and scrap yard sweepings was performed at full-scale, pilot-scale and lab-scale in order to find possible preventive solutions for this waste water problem. The results of the leaching tests (with concentrations that frequently exceeded the regulatory limits) showed the importance of the material type (covered storage vs. open air storage) and the leachate characteristics. The particular versus dissolved fraction of specific contaminants was studied for the polluters. This confirms the (potential) applicability of sedimentation and filtration techniques for the treatment of the majority of the leachates, as such as the rainwater run-off as a whole.
