This study critically examines recent developments in key ship recycling nations, shedding light on both opportunities and challenges faced by this evolving industry. By delving into the socio-economic benefits and presenting a nuanced assessment of the current state of ship recycling, this research aims to bridge the gap between perceived risks and untapped potential. Furthermore, a strategic analysis using SWOT (Strengths, Weaknesses, Opportunities, Threats) methodology is employed to dissect the ship recycling landscape in South Asian countries. This analysis discerns the inherent strengths and opportunities that can be harnessed for sustainable growth, while also acknowledging and addressing the weaknesses and threats that demand careful consideration in the execution of ship recycling operations. This comprehensive exploration underscores the urgent need for a holistic understanding of the ship recycling industry, fostering dialogue and collaboration towards fostering responsible practices and maximizing the positive impact of ship recycling on both local economies and global sustainability goals.</p></div>","PeriodicalId":100598,"journal":{"name":"Green Technologies and Sustainability","volume":"2 2","pages":"Article 100064"},"PeriodicalIF":0.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S294973612300057X/pdfft?md5=eba301766e6df049c6a045643a563299&pid=1-s2.0-S294973612300057X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139193847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process takes a novel low-carbon methanol production method and reduces its emissions further by integrating a solar thermal energy (STE) system to provide for its electricity requirements. The authors investigate three different scenarios for the STE system, analysing the effects of solar irradiance design point, and the impact of thermal energy storage on system performance. Case-1 (15.57 MW) was designed for daytime operation and sized for the maximum annual solar irradiance, with Case-2 (24.91 MW) incorporating thermal energy storage to enable 24-hour operation. Case-3 (48.66 MW) also utilised thermal energy storage to enable 24-hour operation, but was sized for the minimum annual solar irradiance. The methanol process and the STE system were modelled in Aspen Plus and Aspen HYSYS, with the simulation data being used with mass and energy balances to conduct a techno-economic and greenhouse gas emissions assessment. The standalone methanol plant was estimated to emit 0.37 t CO<sub>2</sub>/t CH<sub>3</sub>OH, with the integration of the STE system reducing this to 0.29 (Case-1), 0.23 (Case-2), and 0.10 (Case-3), resulting in one of the lowest emitting traditional methanol production methods available. The cost of abatement of these remaining emissions through carbon capture and storage was also considered. The economic analysis found that the integrated processes in Case-1 and 2 were financially viable, resulting in a net present value of $247 million and $72 million respectively. The net present value was reduced to $185 and $21 million when considering the cost of carbon capture and storage.

Technological advancements combining traditional manufacturing processes with cutting-edge technologies may safeguard the textile industry’s supply chain. To establish stability in the value chain of the textiles sector in emerging nations, it is crucial to precisely identify the relevant barriers to combining advanced technologies with traditional textile practices. Consequently, this study aims to determine the significant barriers to merging technological advancements with conventional textile practices and assess their relationships using an integrated framework. To highlight, measure, and analyze the hierarchical interconnections of the barriers to integrating technical innovations in the textile industry in the context of an emerging economy, this study combines fuzzy theory, Pareto analysis, and total interpretive structural modeling (TISM). Following that, the Matriced’ Impacts Cruoses Multiplication Applique a Un Classement (MICMAC) analysis, clusters of barriers, depending on their levels of driving and dependence power, were developed. Based on the literature review and feedback from experts, a total of 19 barriers were discovered, and Pareto analysis was applied to analyze the major and trivial barriers. Based on that analysis, a myriad of evaluations is done for the top barriers (13- to be precise), and their interrelationships have been investigated using fuzzy TISM-fuzzy MICMAC. Lack of government support policies and insufficient incentives, heavy taxation &amp; inadequate capital investment have been identified as the most crucial barriers. The hierarchical model and study’s findings will assist leaders in the textile industry in applying key concepts in strategic planning and decision-making to successfully combine cutting-edge tools and technologies with traditional textile industry practices and ensure a sustainable global textile supply chain.</p></div>","PeriodicalId":100598,"journal":{"name":"Green Technologies and Sustainability","volume":"1 3","pages":"Article 100039"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49704786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
