Innovations are required for electric vehicles (EVs) to be lighter and more energy efficient due to the range anxiety issue. This article introduces an intelligent control of an organic structure solar supercapacitor (OSSC) for EVs to meet electrical load demands with solar renewable energy. A carbon fibre-reinforced polymer, nano zinc oxide (ZnO), and copper oxide (CuO) fillers have been used in the development of OSSC prototypes. The organic solar cell, electrical circuits, converter, controller, circuit breaker switch, and batteries were all integrated for the modelling of OSSCs. A carbon fibre (CF)-reinforced CuO-doped polymer was utilised to improve the concentration of electrons. The negative electrodes of the CF were strengthened with nano ZnO epoxy to increase the mobility of electrons as an n-type semiconductor (energy band gap 3.2–3.4 eV) and subsequently increased to 3.5 eV by adding 6% π-carbon. The electrodes of the CF were strengthened with epoxy-filled nano-CuO as a p-type semiconductor to facilitate bore/positive charging. They improve the conductivity of the OSSC. The OSSC power storage was controlled by an adaptive neuro-fuzzy intelligent system controller to meet the load demand of EVs and auxiliary battery charging. Moreover, a fully charged OSSC (solar irradiance = 1000 W/m²) produced 561 W·h/m² to meet the vehicle load demand with 45 A of auxiliary battery charging current. Therefore, the OSSC can save 15% in energy efficiency and contribute to emission control. The integration of an OSSC with an EV battery can minimise the weight and capacity of the battery by 7.5% and 10%, respectively.

The rapid increase in the population, urbanization, increasing standard of living, indifference, and other factors can be used to explain the concerning rate of waste generation. Research suggests that most countries prefer to process and dispose of their waste via open dumping or landfilling due to its affordability and simple mechanism. However, leachate and landfill gas emissions present environmental risks associated with landfilling. To prevent landfilling’s detrimental impacts on the ecosystem, alternative methods of disposing of organic waste need to be investigated. An environmental impact analysis was undertaken utilizing the openLCA software to evaluate the ecological footprints of three distinct waste management strategies i.e., Landfilling, Composting, and composting using EP-50 assessing four key environmental indicators. Composting using EP-50 (EcoProbe 50) is a recent advancement towards waste management where organic waste is turned to compost artificially under high temperature and pressure along with constant mixing and churning of the waste for better nutrient value. The EP-50 composter, according to our research hypothesis, offers a greener option to conventional landfilling and composting. We evaluated the potential for global warming, acidification, eutrophication, and human toxicity of landfilling, conventional composting, and EP-50 composting utilizing Life Cycle Assessment (LCA). According to our findings, the EP-50 system minimizes the potential for global warming to around 420 kgCO2 eq in comparison to 1243 kgCO2 eq from conventional composting and 4653 kgCO2 eq for landfilling. In addition, EP-50 increases the amount of nutrients in the compost generated while reducing the effects of eutrophication and acidification by more than 15%. These results demonstrate EP-50 as a scalable and effective method for managing organic waste.

This study presents an integrated Life Cycle Sustainability Assessment (LCSA) of the Natural gas-to-methanol (NGTM) and methanol-to-gasoline (MTG) pathways using Aspen HYSYS process modeling, Environmental Life Cycle Assessment (LCA), Social Life Cycle Assessment (SLCA), and Life Cycle Costing (LCC). The results reveal significant variability in sustainability performance across process units. The DME and MTG Reactors Section generates the highest direct greenhouse gas (GHG) emissions at 0.86 million tons CO₂-eq, representing 54.9% of total global warming potential, while the Compression Section consumes 2717.5 TJ/year of energy, making it the dominant source of electricity-related indirect emissions. Distillation and Purification withdraws 31,100 Mm³/year of water—approximately 99% of total demand—yet delivers 86.6% of the overall economic surplus despite high operating costs. Social impacts concentrate in the Methanol Reactor Looping and DME and MTG Reactors Sections, with human health burdens of 305.79 and 804.22 DALYs, respectively, due to catalyst handling and high-pressure operations. Sensitivity results show that methanol purity rises from 0.9993 to 0.9994 with increasing methane content, while gasoline output decreases from 3780 to 3520 kg/h as natural gas flow increases. The findings provide process-level evidence to support sustainable development of natural gas-based fuel conversion industries, aligning with Qatar National Vision 2030 objectives for industrial diversification and lower-carbon energy systems.
