“…The separation and classification of this multilayer packaging into elemental components is technically difficult; thus such kinds of material are mainly disposed of through incineration and in landfills without any material cycling, which may cause serious environmental pollution such as the contamination of soil and groundwater. Recently, several lab techniques have been developed for the recycling of APPW such as thermal treatment to recycle the energy and Al metal, , and mechanical or chemical technology to exfoliate and dissolve polymer from Al with the aid of chemical solvent and followed by materials recovery. , Although some potential value may be present in these methods, the risk of secondary pollution, high cost, troubles in treatment of the waste solvent, and lack of commercial value of incomplete separation outcomes are still problems for industrial-scale production. Therefore, there is still an urgent issue in developing environmentally benign technology for the production of value-added products from APPW.…”

Aluminum–plastic multilayer films have been widely used in the packaging industry, but the recycling of such a material is a great challenging task. Herein, we reported a facile route to produce value-added composites with high thermal conductivity and high electrical insulation from aluminum–plastic package waste (APPW) for the first time. Briefly, solid-state shear milling (S3M) technology was applied to prepare ultrafine APPW powder and exfoliate expandable graphite (EG) into graphite nanoplatelets (GNPs) with a lateral dimension of 1–5 μm which constructed the conductive network. For the blocking of electron transfer through the aluminum/GNPs network in composites, an in situ oxidation process was employed for aluminum flakes to form a nano-Al2O3 electronic insulation layer around the aluminum flakes, whereas phonons can transport through this barrier layer easily. As a result, the APPW/GNPs composites exhibit an excellent balance of thermal conductivity and electrical insulation, well above all reported data to date on graphite or graphene/polymer composites, with a thermal conductivity of 1.7 W/(m K) and electrical conductivity of 10–10 S/cm. Furthermore, enhanced mechanical strength and stiffness are achieved in APPW/GNPs composites. Such materials could have potential applications in the electronic industry and turn an environmental pollutant into a valuable resource.

“…Although aluminum is prone to oxidation under all conditions, the detected oxidation the of aluminum extracted from LAl in this research (Figure g–i) is comparatively lower in concentration at ∼15.05% (identified by the spectra for aluminum 74.44 eV and for oxygen at 531.75 and 530.13 eV). The atomic percentage of residual carbon is ∼67.31% (identified by the spectra at 284.5 and 285.3 eV).…”

Flexible laminated metals (LMs) made of multilayer polymers and metals are favorable for packaging materials due to their flexibility, low cost, durability, and resistance to corrosion and breaking. However, the complexities of recycling these multimaterials means they are usually deposited in a landfill and hazardous for the environment. This research explores thermal disengagement technology (TDT)an innovative and effective technique for recycling hazardous multilayer materials irrespective of their type and qualities. This process successfully extracted high-quality metals from the accrued metals and polymers. The surface oxidation of the recycled metals was low, and the loss of metal quantity was insignificant. A small amount of CO2 and a significant amount of fuel gases (H2 and CH4) were released during the process. This study also investigated the synthesis of biofuel during the thermal degradation of the laminated polymers. The emitted gas was analyzed with a gas chromatograph-mass spectrometer (GC-MC) and found to consist mainly of aromatic compounds. This research shows that TDT could be used to effectively and economically recycle any kind of market-available flexible metal–polymer multilayer material. This will improve its environmental sustainability by reducing landfill waste as well as the economic benefits of recovering valuable metals and fuel gases.
