“…Aluminum wastes, mainly, are disposed of in landfill sites, which may result in leaking of toxic metal ions into the ground water. Also, when aluminum waste comes in contact with water it emits poisonous gases as NH 3 , CH 4 , PH 3 , H 2 , and H 2 S [10,11]. The environmental effects of aluminum scrap from recycled aluminum should be minimized.…”

The worldwide recycled aluminum generation is increasing quickly thanks to the environmental considerations and continuous growing of use demands. Aluminum dross recycling, as the secondary aluminum process, has been always considered as a problematic issue in the world. The aim of this work is to propose a methodical and easy procedure for the proposed system selection as the MCDM problem. Here, an evaluation method, integrated FAHP, is presented to evaluate aluminum waste management systems. Therefore, we drive weights of each pair comparison matrix by the use of the goal programming (GP) model. The functional unit includes aluminum dross and aluminum scrap, which is defined as 1000 kilograms. The model is confirmed in the case of aluminum waste management in Arak. For the proposed integrated fuzzy AHP model, five alternatives are investigated. The results showed that, according to the selected attributes, the best waste management alternative is the one involving the primary aluminum ingot 99.5% including 200 kg and the secondary aluminum 98% (scrap) including 800 kg, and beneficiation activities are implemented, duplicate aluminum dross is recycled in the plant, and finally it is landfilled.

“…Direct applications as raw materials in the refractory brick [16] or in the production of inert filling for construction, road paving, mortar components, polymer composites, adsorbents, and mineral wood have been reported [17]. While other researchers have aimed to use them to manufacture other raw materials such as hydrogen gas [18], X-zeolites [19], aluminum sulfate (Al2(SO4)3.18H2O) [20] and alumina with different properties for many applications like catalysis [21,22], cement [23], biomaterials [24] and refractory [16].…”

In this study, a high valued product submicronic ?-alumina is successfully extracted from aluminum slags generated by the local aluminum industry. The extraction technique is based on the leaching of slags by H2SO4 followed by precipitation. The coarser aluminum-rich fractions of the slags are used in this study instead of the finer oxide-rich fractions that were commonly used in previous studies. The precipitation of the leached slags by NH4OH is controlled by zetameter in order to determine the optimal precipitation pH. Then, the obtained gel showing the higher precipitation rate and the finer particle size is calcined at 1200 ?C and characterized by XRF, XRD, FTIR, SEM, EDS and laser granulometry. Even without any pretreatment of slags, the XRF analysis reveals that a high purity and high extraction efficiency of 99.2% and 93.75% respectively can be achieved just at a leaching acid concentration of 15%. XRD spectrum shows that the produced alumina is a pure a-corundum, which is confirmed by FTIR spectrum showing only the Al-O bonds. The laser granulometry shows that the recovered powder exhibit a wide particle size distribution. It is between 50 nm and 20 ?m while the average particle size (d50) is about 400 nm. SEM observations reveal that the grains are in the form of submicronic whiskers. The above characteristics allow the obtained alumina powder in this study to be used in the usual applications of alumina such as refractory, ceramic fibers, abrasive, etc. The obtained powders may assume also applications as a thermally stable substitute for the commonly used transition alumina powders, which need further investigations in future studies.

“…[ 19 ] In one of these studies, Adeosun et al prepared PP/Al‐dross composites by adding Al‐dross into the PP phase by 2–50% wt. [ 20 ] The authors reported that the ultimate tensile strength of PP improved by 68% (at 15% wt. Al‐dross addition), and the impact resistance did not change considerably for the 15% wt.…”

In this study, different amounts of aluminum dross (Al‐dross) powders were incorporated into polyoxymethylene (POM) by the melt‐mixing method, and morphological, thermal, rheological, mechanical and dielectric properties of the obtained composite samples were investigated. So, it was aimed to develop value‐added products and create an alternative utilization method for industrial waste that poses environmental risk and does not have a useful application area. The morphological analyses performed by scanning electron microscopy (SEM) showed that the Al‐dross contained various inorganic components with different particle sizes such as Al2O3, NaCl. Moreover, no significant structural incompatibility between the POM and Al‐dross was observed. In contrast, the SEM analyses showed non‐coated filler particle surfaces, which were probably due to the breaking of NaCl particles during the extrusion process. In the differential scanning calorimetry (DSC) analysis, it was found that the effect of Al‐dross addition on the crystallization temperature, amount of crystalline structure in the polymer phase or crystallization rate was limited. The rheological analyses showed that the Al‐dross particles formed rheological percolated structures at an Al‐dross ratio of 20% wt. In the dynamic mechanic analysis (DMA), it was observed that the modulus of elasticity (E') increased by approximately 40% and creep strain decreased by approximately 50% by the addition of Al‐dross into the POM phase at the 40% in %wt. Finally, in the dielectric analyses carried out in the frequency range of 1–14 GHz by a vector network analyzer, it was concluded that incorporating Al‐dross at 40% caused an increase of 1.5 and 3 times in real and imaginary part of the complex permittivity.
