“…When such practices are promoted, it is anticipated that the associated carbon footprint of the plastic products conversion will reduce. This is due to the reduction on the dependency on petrochemical based processes associated with virgin resin production and conversion to plastic articles [55,56]. This can result in an industrial scale operation that can treat such type of SW.…”

Polyolefin (PO) polymers constitute the majority of consumer plastic commodities. The reliance on such materials make it near imposable to avoid touching one in any given day. Therefore, the accumulation of plastic solid waste (PSW) in developed and developing societies alike requires immediate attention to manage and valorize this type of waste. In this work, PSW originating from real life sources and virgin linear low-density polyethylene (LLDPE) films were compounded in a mechanical recycling effort. The recycled blends constituted up to 100% (by weight) of the waste material. Accelerated weathering (aging) was conducted on the blends, reaching threshold limit of exposure to study the major changes occurring on the recycled blends. Thermogravimetry and differential scanning calorimetry (DSC) were used to determine their characteristics and applicability for future recycling using thermo-chemical treatment (TCT) methods. Analytical solution methods following the international committee of thermal analysis and calorimetry (ICTAC) were followed in conducting the measurements and kinetic calculations alike. A novel analytical mathematical solution model is also introduced to determine both the pre-exponential factor (Ao) and apparent activation energy (Ea) of the degradation reaction. The model proved to be a more accurate analysis tool, and the work in whole enabled the determination of future plans for using such waste components as a feedstock to thermal units.

“…Their enhanced surface-area-to-volume-ratio leads to a much-improved mass and heat transfer, in addition to, shorter residence time. Therefore, reactions which contain unstable intermediates are better suited to these type of reactors because of their stability and high degree of control 11 . These collective advantages of microreactors mean that they are greener and environmentally sustainable 12 .…”

“…Essentially, any carbon source can be used as the feedstock for the Fischer-Tropsch process to obtain alternative fuels. The Fischer-Tropsch process can produce a wide range of products which can then be upgraded to obtain the desired hydrocarbon fractions (Hafeez et al 2018). The Fischer-Tropsch reaction is highly exothermic with reaction temperatures ranging between 300 to 350 °C under high pressures using iron-, cobalt-and ruthenium-based heterogeneous catalysts (Guettel et al 2008).…”

“…On the other hand, cobalt tends to be more expensive than iron (Guettel et al 2008;Hafeez et al 2020). A more detailed account of the mentioned fuel production routes and technologies can be found in Hafeez et al (2018Hafeez et al ( , 2020.…”

Population growth has led to higher consumption of fossil fuel, and subsequently to a major increase of greenhouse gases emissions to the atmosphere, thus inducing global warming. Fossil fuel supplies are depleting, and the price of these fuels is increasing. Moreover, there are concerns about related emissions of toxic pollutants such as sulphur dioxide and aromatic hydrocarbons. Here, we review alternative fuel technologies. We focus on how membrane reactors improve the existing production processes of renewable fuels. Advantages and environmental benefits of membrane reactors are compared to the conventional techniques. Membrane reactors have been applied successfully to improve biodiesel, hydrogen and Fischer-Tropsch synthesis. Membranes help the conversion of products, whilst shifting the equilibrium of the reaction and reducing undesired by-products. Membrane reactors also overcome immiscibility issues that hinder conventional reactor processes. Overall, membrane reactors reduce cost and energy needed for the treatment of wastewater from fuel production.
