Chapter 2 - Green Engineering and Sustainable Design Aspects of Waste Management

The emission crisis in the iron and steel sector prompted the search for modern systems that contribute to reducing the resulting emissions to alleviate the growing concerns about global warming. This research evaluates four flue gas treatment systems in the iron and steel sector through a case study in Egypt. A comprehensive approach is presented through which experts can use linguistic terms and their corresponding spherical fuzzy numbers (SFNs) to express their views on identifying aspects and indicators that affect the sustainability of flue gas treatment systems. Also, determining the optimal system for dealing with emissions is a necessary task, which requires consideration of many aspects of sustainability, including economic, environmental, and technological aspects and their subindicators. This paper presents a new hybrid approach to multicriteria decision-making (MCDM) under a spherical fuzzy (SF) environment that takes into account several incompatible indicators. The SF-CRiteria Importance through Intercriteria Correlation (SF-CRITIC) has been used to assess and prioritize the main aspects and subindicators. The SF-COmbinative Distance-based ASsessment (SF-CODAS) has been applied to evaluate and rank the selected systems. A sensitivity analysis has been implemented to confirm the effectiveness of the recommended hybrid approach and the stability of its results by changing the weights of the indicators used. Also, a comparative analysis has been fulfilled with MARCOS and WASPAS methods under an SF environment to validate the proposed approach. The findings show that the environmental aspect is the highest evaluated with a weight of 0.431, followed by the technological aspect with a weight of 0.326, and they are the basis for enhancing the sustainability of low-emission systems in the iron and steel sector. Furthermore, the conclusions advise optimizing low-emission systems for sintering flue gas in the iron and steel sector to improve sustainability.

This paper first considers the underlying nuclear physics and then explores the potential application of that science to the propulsion of merchant ships. It then examines the options for the exploitation of nuclear technology and considers some of the engineering implications of deploying the technology. Consideration is then given to the application of nuclear propulsion to a series of ship types, including tankers, container ships and cruise vessels. In each case two sizes of ship are chosen, one of fairly conventional size and the other much larger.

An educational effort was undertaken at Georgia Southern University that sought to incorporate the three aspects of Sustainability, environment and technology into a single course. An effort was also made to tie these three seemingly diverse constituents into one coherent course at the introductory level. This paper seeks to present the results of that effort. Audio-visual media are the chosen field of instruction to facilitate knowledge transfer to students. Some of the aspects that receive attention include geology, business case for sustainability, recycling, disassembly and green manufacturing etc. The basic objective of this course is to bring together students from various educational backgrounds in one place and encourage critical and creative thinking using a systems approach. The course focuses on hands-on activities such as mini-design projects that challenge students to think creatively and make some aspect of any chosen system more sustainable.

It is great pleasure for me to welcome you to Kuala Lumpur, Malaysia for the Third IEEE Conference on Sustainable Utilization and Development in EngiNeering and Technology (IEEE STUDENT 2012). I would like to thank all of you for coming to the conference to participate and exchange ideas and advances in all aspects of sustainability and technology.

Engineered nanomaterials in microbial fuel cells – Recent developments, sustainability aspects, and future outlook

In recent times, sustainable development has been the primary focus of research and development in the pavement industry. In this respect, microsurfacing was viewed as sustainable pavement preservation and has emerged as a cost-effective pavement maintenance alternative for enhancing performance, increasing service life, and ensuring safety with minimal environmental impact. In this review, the impact of microsurfacing application on the economic, social, and environmental components were explored from the published literature. Studies show that with microsurfacing application, there was a 31 % savings in cost as compared with conventional hot-mix asphalt. Furthermore, a brief economic analysis was carried out, which confirmed microsurfacing as one of the most cost-effective preventative treatment with minimum equivalent uniform annual cost. However, the economic benefits of microsurfacing were dependent upon distress type and intensity, pavement age, climatic conditions, and traffic volume. In addition, the social benefits included enhanced skid resistance, reduced hydroplaning, better riding quality, and pleasing aesthetic appearance. Moreover, the main environmental benefits of microsurfacing, as reported by various researchers, included low energy consumption, reduced greenhouse gas emission, conservation of natural resources, and reduction in tire-pavement noise. Review also reported the strength, weakness, opportunities, and threats of microsurfacing application. Even with certain weakness and probable challenges, application of microsurfacing showed enormous potential for further improvement. Incorporation of recycled or waste materials, compaction prior to opening for traffic, and project-related specifications are some areas for further research. However, certain challenges, like insufficient fund allocation, implementation or performance issues, and production variability, had to be mitigated for smooth and rapid development. Thus, with encouraging results and a promising future, microsurfacing had excelled in both technological and sustainability aspects.

The quantitative and qualitative performance analysis of ChatGPT-3.0, a large language model, is carried out on three important and highly competitive examinations held in India: civil services examination (CSE, prelims), graduate aptitude test in engineering (GATE), and joint entrance examination (JEE). These examinations cover general knowledge, current affairs, history, geography, Indian polity, economics, mathematics, physics, chemistry, engineering, and technology aspects at the undergraduate and graduate levels. The Accuracy, Concordance, and Insight (ACI) criteria is used to analyze the performance of ChatGPT. ChatGPT passed CSE without much specialized training and reinforcement, however, underperformed in GATE and JEE. Overall, the average accuracy rate of ChatGPT is 48.71%, with a 44.45% concordance for all explanations. However, the concordance for accurate explanations is found to be 91.87% with a high level of insights given in the explanations. Moreover, the average accuracy of ChatGPT improves to 77.69% after training. The results suggest that large language models have great potential to assist with education technology and act as an instructor for the preparation of technical, aptitude and general studies topics for competitive examinations. Drawing insights from the findings of the current research, some limitations in the present study and possible future research directions are suggested.
