“…There are two main components in the decomposition of polyethylene: char and aluminum. These results agree with the previous studies (Korkmaz et al 2009;Wu and Chang 2001). TGA results showed that weight loss of aluminum-polyethylene was over at the temperature of 500°C.…”

This work evaluates the use of aluminum contained in the aluminum-polyethylene films as anodic electrodes using the electrocoagulation technique to reduce the pollutant contents of industrial wastewater quickly and effectively. Thermal treatment at 500°C produces pure aluminum (according to TGA and SEM/EDS analysis) which is used to construct aluminum disks (applying 6 tons/cm 2 of pressure). Aluminum disks are used as cathodes and anodes in an electrochemical cell. The current density applied in the recovered Al electrodes was 12 mA cm -2 , and the maximum COD reduction of wastewater was 77 % at 25 min of treatment. The color and turbidity reductions are 87 and 90 %, respectively. The resulting sludge of wastewater treatment was thermally treated and a second aluminum recovery was reached; since the organic material present in the sludge was removed by the high temperature, the obtained aluminum was pure enough for its reuse. The use of aluminumpolyethylene films as electrodes in the electrocoagulation process contributes to the pollutant removal without the addition of chemical reagents or changing the pH, so it is both effective and environmentally friendly.

“…Previous studies suggested that panel products from waste cartons could be an alternative raw material in the laminate industry by using suitable adhesive due to its improved mechanical properties, increased water resistance, and high biological performance against decay fungi and insects (Murathan et al 2007;Ayrilmis et al 2008;Sen et al 2010;Hidalgo 2011). Thermal degradation characteristics and pyrolysis characteristics of TP waste were also studied (Kanturk Figen et al 2013;Wu and Chang 2001;Korkmaz et al 2009). …”

Degradation Behavior and Accelerated Weathering of Composite Boards Produced from Waste Tetra Pak® Packaging Materials

Manufacturing panels from Tetra Pak ® (TP) packaging material might be an alternative to conventional wood-based panels. This study evaluated some chemical and physical properties as well as biological, weathering, and fire performance of panels with and without zinc borate (ZnB) by using shredded TP packaging cartons. Such packaging material, a worldwide well-known multilayer beverage packaging system, is composed of cellulose, low-density polyethylene (LDPE), and aluminum (Al). Panels produced from waste TP packaging material were also examined by FT-IR to understand the fungal deterioration and extent of degradation after accelerated weathering. Before FT-IR investigations, panel specimens were ground under nitrogen atmosphere due to nonuniformity of the composite material. The FT-IR results showed that fungal degradation occurred in the natural polymer of the panel matrix. Although the natural polymer is mostly composed of cellulose, there were also small amounts of polyoses and lignin. It was seen that especially polyose and lignin bands in FT-IR spectra were affected more than cellulose bands by fungal attack. No changes were observed by the fungi in the plastic component (LDPE) of the matrix; however, LDPE seemed more sensitive to weathering than cellulose. Incorporation of ZnB at loading level of 1% (w/w) did not contribute fire performance of the panels when compared to control panel specimens, while a loading level of 10% improved fire performance considering test parameters such as mass loss, ignition time and peak heat release rate.

“…The existing technologies for separating aluminum and polyethylene include wet process (Cao, 2009;Han, 2007;Wang and Wang, 2005;Xie, 2002;Zhang et al, 2011) and dry process (Hans and Paul, 1995;Hyder and Tommy, 1995;Jorma et al, 2002;Parkinson, 2005;Wu and Chang, 2001). In recent studies, most attention has been paid to wet process separation technologies http://dx.doi.org/10.1016/j.wasman.2014.10.008 0956-053X/Ó 2014 Elsevier Ltd. All rights reserved.…”
