Item Restricted A KPIs Framework for Minimizing Environmental Impacts from Chemical Manufacturing Processes: The Case of Saudi Arabia(Saudi Digital Library, 2025) الفارسي, علاء عبدالرحمن; Jagtap, SandeepThe goal of this study was to create a complete framework to make Saudi Arabia's chemical industry more environmentally friendly by focusing on emissions, pollutants, and resource use. A mixed research approach was utilized, encompassing a systematic literature review, surveys, and case studies. Statistical Package for the Social Sciences (SPSS) was used to investigate quantitative data, while Non-Versioned Information, Versatile Outcomes (NVIVO) was applied to look at qualitative data from interviews to make sure we had many different types of data. finding Key Performance Indicators (KPIs), measuring and analyzing them, judging performance, and making things better all the time. Results showed that there were big gaps in efforts to cut emissions, and that the average performance in resource use was below industry standards. The use of SPSS analysis showed that KPI performance was statistically different between organizations. NVIVO, on the other hand, helped find important qualitative insights about the problems that organizations face when trying to implement sustainable practices. The tiered rating system was used to rank organizations, and those that had emissions and energy use below the baseline were given specific plans to help them do better. The study found that chemical organizations could cut emissions by 15% and improve resource efficiency by 10% in just two years by using this framework. This would help them meet both regulatory and sustainability goals.21 0Item Restricted Development of a method to capture and quantify emissions from open burning of explosives(Cranfield University, 2024) Alqahtani, Waleed; Wardrop, Josh; Persico, Federica; Temple, TraceyThis thesis presents the development of a method for capturing and quantifying gaseous emissions resulting from the open burning of explosives. The environmental impact of military explosives disposal, particularly through open burning and detonation, necessitates improved emission monitoring techniques to mitigate pollution and health risks. Four commonly used explosives, RDX, TNT, NTO, and nitrocellulose, were selected for this study due to their widespread application in military and industrial settings. A bespoke gas collection system was designed to capture emissions from controlled open burning experiments, with Fourier Transform Infrared Spectroscopy (FTIR) employed for real-time gas analysis. The system was validated using inert materials such as cellulose and paraffin wax, ensuring the accuracy and reliability of the emission quantification process before analysing explosive samples. The FTIR analysis identified key emissions, including CO₂, CO, N₂O, H₂O, and NOx, which were quantified and compared to theoretical predictions based on the combustion of each explosive. The results revealed significant variations in emission profiles between different explosives, highlighting the environmental hazards posed by traditional disposal methods. The findings from this study underscore the importance of accurate emission capture and analysis to inform safer explosive disposal practices. This research contributes to a deeper understanding of the gaseous by-products of open burning, advocating for enhanced monitoring frameworks to reduce the ecological footprint of explosive ordnance disposal operations.31 0Item Restricted Development of a method to capture and quantify emissions from open burning of explosives(Cranfield University, 2024) Alqahtani, Waleed; Wardrop, Josh; Persico, Federica; Temple, TraceyThis thesis presents the development of a method for capturing and quantifying gaseous emissions resulting from the open burning of explosives.

This dissertation delves into the economic viability of blue hydrogen production in Saudi Arabia with the focus of the forecasting of production costs. By encompassing the evaluation of various hydrogen types, blue hydrogen applications, and an estimation of production costs according to historical feedstock prices. The literature review scrutinizes different hydrogen types with their economic feasibility in the context of blue hydrogen production. Consideration of cost competitiveness, environmental impact, and scalability lays the groundwork forward to insights. Furthermore, the examination of blue hydrogen's applications elucidates industries poised to benefit from future possible investments in this energy carrier, while also diving into potential challenges and opportunities. Employing a meticulous methodology, forecasting the production cost of Saudi blue hydrogen, placing particular emphasis on feedstock prices. By utilizing ARMA model to leverage forecasted natural gas prices, thereby shedding light on the relationship between feedstock costs and hydrogen production expenses. The results and recommendations have strategic insights and actionable suggestions. By comparing decisions made at the oil and gas industry, this dissertation positions itself at the intersection of industry growth stages. The findings offer suggestion for a transition from the emerging phase to the mature phase in early growth market, with an emphasis on cost-saving strategies and optimizing resource. A pivotal finding emerges in understanding the influence of natural gas prices on production costs of Saudi Aribia.
