“…The application of wet high intensity magnetic separation to remove As, Cu, Pb, and Zn from a sandy loam soil from a mining site was studied by Sierra et al (2014). Extraction of Cu from artificially contaminated sediments through the use of electro kinetic process driven by a galvanic cell (Yuan et al, 2009) was also reported.…”

During the last 40 years the existing solid waste handling system schemes have been developed and implemented including advanced systems for recovery and reuse. However, even though these recycling systems have not been always economically feasible during the entire period, recycling systems have been implemented thanks to the wide support from the citizens and their interest for source separation. There has been a feeling among citizens and even waste management companies that this is a sustainable and nature resources saving way to work. Today "the zero waste concept" is used more and more both in Sweden and other parts of the world discussing different ways of modern waste management in order to reduce the amount of waste for final disposal as much as possible close to zero. The existing challenges in the future include recovery of metals, nutrients, and other valuable constituents that have escaped from the anthropogenic circuits since the industrial. During the next 30 years more focus must be directed towards recovery of lost resources in ore mining waste, old landfills, in harbor and sea sediments, slag, ashes, sludge but also materials that are bound to urban constructions as residential, commercial and industrial infrastructures, water distribution networks, sewage systems and underground electric/electronic networks such as telephone etc. An overview regarding the recovery of mentioned materials and chemical compounds called "Beyond the zero waste concept" will be presented in this paper in order to raise concerns and awareness about the importance of establishing a new model of waste management schemes..

“…The low pH environment near the anode favors desorption of metallic contaminants (e.g., Cu and Pb) from the soil (Maini et al, 2000). The dissolved metallic ions are then reduced at the cathode (Yuan et al, 2009) to formed metal precipitates, which can be readily removed or even recovered.…”

“…Kaolin is a representative clay soil with a similar viscosity to sediment, and can thus be used as a simulated sediment (Yuan et al, 2009). A real top sediment sample was obtained using an Eijkelkamp core sampler from the center of the Veliki Backi canal (water depth ranging from 2.0 to 5.5 m).…”

In this work, the simultaneous application of bipolar electrodes and a longer cathodic compartment length without agents addition was used as an enhanced electrokinetic treatment of Ni-, Cd-, and Pb-contaminated sediment. Conventional and enhanced treatments were investigated and their efficacy assessed by comparing the residual metals content in the sediment with values given by Dutch standards. After conventional treatment removals of 20%, 19%, and 31% for Ni, Cd, and Pb were achieved, whereas the enhanced treatment achieved removal efficacies of 36% for Ni, 42% for Cd, and 43% for Pb. Results indicate that the simultaneous application of the techniques mentioned is effective for removing Ni and Pb whereas Cd was not removed to the desired level.Here we show that the addition of chemicals is not necessary to increase the efficacies of electrokinetic sediment treatments, so the simultaneous application of the techniques mentioned can be described as environmentally friendly.
