Abstract:Sludge from cardboard mill is most commonly landfi lled, but it could also be recycled on-site into production or reused in some other way. In this study the use of sludge from cardboard mill as stabilizing agent in the stabilization treatment of cadmium polluted sediment was examined. The effectiveness of treatment and long-term leaching behavior of cadmium was evaluated by determining the cumulative percentage of cadmium leached, diffusion coeffi cients (De) and by applying different leaching tests (semi-dynamic test, toxicity characteristic leaching procedure, waste extraction test). In order to simulate the "worst case" leaching conditions, the semi-dynamic leaching test was modifi ed using 0.014 M acetic acid (pH = 3.25) and humic acids solution (20 mg l -1 TOC) as leachants instead of deionized water. A diffusion-based model was used to elucidate the controlling leaching mechanisms. Applied treatment was effective in immobilizing cadmium irrespective of high availability in the untreated sample. The controlling leaching mechanism appeared to be diffusion, which indicates that a slow leaching of cadmium could be expected when the cardboard mill sludge as stabilization agent is applied.

“…The intensive use of waste water irrigation, sewage sludge, pesticide and emissions from vehicle exhausts, mining, smelting and the rapid development of industries without effective control has resulted in a large accumulation of heavy metals in soils [1][2][3][72][73][74][75][76]. Heavy metal pollution of soils is an increasingly urgent problem all over the world.…”

“…For example, paper mill sludge, an industrial by-product mainly composed of carbonates, silicates and organic matter, has lower intrinsic ecotoxicity than sewage sludge and was observed to be very efficient in decreasing dissolved concentrations of trace elements (Cu, Pb, Zn, Ni and Cd) and their uptake by plants [169][170][171].…”
