Production of Sustainable Liquid Fuel From Waste Polymeric Materials via Thermal Pyrolysis

The widespread use of polymeric materials has become an environmental threat as they are durable and nonbiodegradable in nature, which is directly responsible for severe ecological consequences. Thermal pyrolysis offers a sustainable and efficient approach to converting these polymeric waste materials into liquid fuel, which is also referred to as pyrolysis oil (PO). In this study, a novel method was developed for producing oil from a composite of waste polymers that include vehicle tires, tubes, and medical waste. A fixed-bed stainless steel reactor is used to thermally breakdown the waste polymeric feedstock (300–750°C) in an inert environment. The PO was characterized by using Fourier transform infrared spectroscopy (FTIR), GC–MS spectroscopy, and 1H NMR to identify its chemical composition, which confirms the presence of long-chain hydrocarbons, both aliphatic and aromatic. The PO undergoes into further characterization for its physicochemical properties, which indicates that it meets petroleum standards and showing its promise as an alternative fuel. The kinetics of pyrolysis processes were investigated in a batch reactor, which indicating its potential for using in large industrial production. This research highlighted the potential of polymeric waste as a sustainable fuel that paves the way for alternative energy sources and minimizing the environment pollution

Combined effects of ternary oxides (Mg-Cu-O) and jute stick derived activated carbon for hydrogen storage in MgH2

The extensive and rising utilization of fossil fuels has had a substantial effect on irreversible global climate change. Therefore, it is imperative to increase the use of alternative energy sources to address this severe issue. Hydrogen is a highly promising energy source that can be stored via a variety of approaches. The current research enhances the H2 storage capacities of MgH2 by incorporating jute stick-derived activated carbon and a ternary oxide (Mg-Cu-O). Different composite nanomaterial samples were synthesized by ball milling and characterized using XRD, TGA, DTA, SEM, EDX, and FTIR. It was observed that both the ternary oxide and activated carbon exhibit a notable effect on H2 absorption and desorption processes. The inclusion of activated carbon increases the surface area, which contributes significantly to the increased adsorption capacity of the samples. On the other hand, the presence of MgCuO2 enhances the H2 desorption rate at lower temperatures. Therefore, the synergistic effects of jute stick-based activated carbon and MgCuO2 can provide highly robust H2 storage materials for alternative energy applications
