A significant rise in global temperature at the end of the century is estimated to be 2.4 °C, which necessitates action. The growth of energy needs urges scholars/researchers to think about developing suitable solutions. The key goal is to achieve zero-net emissions by 2050 in accordance with the goals outlined in the Paris Agreement (Climate Accords). To accomplish this, it is vital to have a strong strategy that initially includes high emissions reduction goals and addresses the challenges of global warming on our planet. Therefore, by 2050, the global energy strategy aims to eliminate emissions from the energy industry to zero. It is worth noting that most energy of the energy consumed comes from transport, power generation, industry, and buildings. The use of renewable technology is a method that is widely recommended to eliminate such challenges. Solar energy has two main technologies: solar photovoltaic (PV) and concentrating solar power (CSP), which have great potential in fulfilling energy needs. This work provides insight into solar energy technology’s role in global decarbonisation and towards net-zero emissions by 2050 through wide deployment and energy yield. The perspectives of solar energy technologies can save the environment by reducing emissions and energy supply, lowering energy bills, and creating job opportunities. Hence, investment in solar energy and other clean energy technologies will substantially achieve sustainable development in the coming decades; as forecasted, solar energy will have great installation capacity worldwide.</p></div>","PeriodicalId":100598,"journal":{"name":"Green Technologies and Sustainability","volume":"2 3","pages":"Article 100107"},"PeriodicalIF":0.0,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949736124000344/pdfft?md5=271130d8918f834bbaf4b4fe8f2bf956&pid=1-s2.0-S2949736124000344-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141397098","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}

With those different alternatives, comparison and the selection of a better-performing material or a building system using diverse perspectives becomes important. Literature shows its complexity in adopting social and cultural dimensions in decision-making that adversely impacted on most desirable material selections in tropical underdeveloped countries as well as indigenous communities. This study proposed an eco-design-based material selection approach that considers the individual and holistic perspective of diverse eco-design indicators such as economic, ecological, social, and cultural. Several sub-themes are identified under each theme and are verified through expert surveys. The identified sub-themes are verified and compared Pairwise through expert surveys and using the Analytical Hierarchy Process leads to proposing weights for each theme and sub-theme and developing an eco-design-based material selection framework. Accordingly, saving energy (10.7%), reducing the overexploitation of natural resources (9.1%), reducing energy emissions (7.9%), and reducing construction (7.3%), as well as operational cost (7.6%), are the parameters that create a greater impact on the selection of sustainable material with the aid of eco-design. Overall, the ecological theme creates the highest impact of around 46% and the cultural theme contributes to a lower percentage of around 5% while the economic and social themes impact considerably 30% and 19% respectively. Furthermore, the developed framework is tested in a case study by comparing an emerging walling material, Cement Stabilized Earth Blocks with conventional materials such as Burnt Clay Bricks and Cement Sand Blocks. Technique for Order Preference by Similarities to Ideal Solution was carried out to compare and rank the respective walling materials under different scenarios. Accordingly, Cement Stabilized Earth Blocks is concluded to be the best alternative when analyzed in the eco-design concept. The proposed framework could be highly beneficial for industry practitioners in tropical underdeveloped countries and indigenous communities in choosing community-preferred, affordable, and environmentally-friendly construction materials.</p></div>","PeriodicalId":100598,"journal":{"name":"Green Technologies and Sustainability","volume":"2 3","pages":"Article 100103"},"PeriodicalIF":0.0,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949736124000307/pdfft?md5=9fecdb1664eec4d36d7a0c6f2de98ef6&pid=1-s2.0-S2949736124000307-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141037869","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 air-sensitive nature of the catalyst requires <em>in-situ</em> impregnation of the porous support material with the liquid phase components (Rh-precursor, ligand, stabiliser) entailing the use of large quantities of an organic solvent. Environment, health, and safety (EHS) as well as regulatory aspects prompt the search for an alternative to dichloromethane (DCM), which was used as standard solvent for lab-scale studies. To obtain alternatives to DCM, the replacement solvent methyl <em>tert</em>-butyl ether (MTBE) and <em>in-silico</em> screening of more than 5000 solvent candidates has been performed covering boiling points and solubility predictions by COSMO-RS as well as carcinogenicity- and mutagenicity predictions by quantitative structure–activity relationship (QSAR) models. The final list of solvent candidates contained unsaturated compounds (alkenes, alkynes) in addition to ether- and ester-functionalized​ solvents, which are typically recommended as DCM replacements. Sufficiently high solubilities of ligand and stabiliser to prepare the desired SLP catalyst were experimentally determined in the following solvents: methyl propionate (MP), dimethoxymethane (DMM), MTBE, tetrahydrofuran (THF) and DCM for benchmarking, and a monolithic SLP catalyst prepared with MTBE demonstrated to perform equally well in the HyFo reaction of 1-butene as the benchmark catalyst prepared using DCM solvent.

The inadequacy of robust waste management systems and limited resources poses significant challenges for many emerging economies, including Bangladesh, resulting in environmental contamination. Despite numerous academic studies on sustainable waste management, there is a noticeable gap in the literature concerning identifying, evaluating, and modeling critical risks associated with adopting sustainable municipal waste management systems, particularly in emerging economies like Bangladesh. This study, therefore, aims to fill this gap by identifying, categorizing, and assessing the crucial risks in implementing sustainable municipal waste management systems. Through an extensive review of existing literature and validation with expert feedback, this study employs a fuzzy synthetic evaluation method-based framework to prioritize the identified risks. The study calculates the probability of occurrence and degree of impact values to provide decision-makers with insights into the severity of different risk categories, aiding in case-by-case attention. Scores assigned on a 1 to 5 scale range from 2.59 to 4.14 for the various risk categories. Notably, “Industrial challenges related” and “Community and infrastructure requirements related” emerge as the most significant risk categories among those analyzed. This study contributes to the existing literature by employing fuzzy synthetic evaluation, a methodology rarely used to determine critical risks in municipal waste management.
