“…Several researchers have focused on the potential for extraction/removal of metals from ashes and slags generated in municipal solid waste incineration plants through different techniques including thermal and hydro-metallurgy (Kuboňová et al 2013), dry discharge of bottom ashes followed by a series of magnets and Eddy currents (Meylan and Spoerri. 2014;Morf et al 2013), fly ashes acid leaching (Meylan and Spoerri.…”

“…Solid waste that has been daily discarded by the society contains several important constituents, for example valuable metals such as zinc, copper, nickel, chromium and lead can be found everywhere. At the same time man are wasting huge volumes of important metal resources, scientific literature has recently highlighted the continuous depletion of natural stocks (including metals) resulting in higher prices in the metal market (Meylan and Spoerri, 2014). Not only the prices have become higher in the market, but also according to Boesch et al (2014) this trend of increasing natural resources prices is expected to be even more pronounced in the near future.…”

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 comprehensive scope of assessment methodologies such as life cycle assessment (LCA) is suitable for identifying environmental benefits, problem shifting and breakeven points, and criticality related to the management of MSWI BA. Several studies have applied LCAs to analyse specific aspects of MSWI BA valorisation as a support for the implementation of new sorting systems or utilisation options (Barberio et al, 2010;Birgisdóttir et al, 2007;Boesch et al, 2014;Margallo et al, 2014;Meylan and Spoerri, 2014;Muchova, 2010;Toller et al, 2009) or to compare waste management systems where incineration and MSWI BA management are included (Georgeson, 2006;Kuusiola et al, 2012). However, so far, critical aspects such as the influence of recovered metal quality have not been addressed in LCA studies, and often impacts related to pollutants released into the environment during BA utilisation have been disregarded.…”

“…Furthermore, during waste incineration, the heavy metals in waste cannot be destroyed. They then volatilize during incineration and condense later to form metal compounds and submicron metallic particles as the flue gas is cooled (Meylan and Spoerri 2014). The emission characteristics of heavy metals from waste incinerators are mainly affected by the concentration of metals in the waste feed and the operation conditions (Yang et al 2014).…”

The effects of sulfur compounds on the migration of a semi-volatile heavy metal (cadmium) during sludge incineration were investigated with two methods, i.e., experiments in a tubular furnace reactor and thermodynamic equilibrium calculations. The representative typical sludge with and without the addition of sulfur compounds was incinerated at 850 °C. The partitioning of Cd among the solid phase (bottom ash) and gas phase (fly ash and flue gas) was quantified. The results indicate that sulfur compounds in the elemental form and a reduced state could stabilize Cd in the form of CdS, aluminosilicate minerals, and polymetallic sulfides, whereas sulfur in the oxidized forms slightly increases Cd volatilization during incineration. For Cd solidification points, the inhibition effect on the volatilization of Cd is as follows: S > Na2SO4 > Na2S. Chemical equilibrium calculations indicate that sulfur binds with Cd and alters Cd speciation at low temperatures (<950 K). Furthermore, SiO2- and Al2O3-containing minerals can function as sorbents stabilizing Cd as condensed phase solids (CdSiO4 and CdAl2O4) according to the results of equilibrium calculations. These findings provide useful information for understanding the partitioning of Cd and thus facilitate the development of strategies to control Cd volatilization during sludge incineration.
