“…In developing countries, social sector development is not a priority area due to a lack of resources and policy preferences [103,104]. But owing to the sustainability assurance, the modern development strategies, which demand inclusive approaches, have started to advocate for a paradigm shift in this context [105]. As a result, many social engineering-based development programs and plans are launched aiming at offering social equities and inclusion [100,106].…”

Economic growth, social wellbeing, and infrastructure are strongly interrelated and jointly contribute to national development. Therefore, evaluation and selection of a road infrastructure project direly need a comprehensive sustainability assessment integrating holistic decision criteria. This study presents an elaborate life cycle sustainability-based project evaluation tool, comprising an assessment framework, an integration model, and a decision framework. In the first phase, a life cycle sustainability assessment (LCSA) framework for road infrastructure is established using mixed methods. In the second phase, interviews are conducted to obtain pairwise comparisons among impact categories and subjective reasoning of their priorities. Analytical hierarchy process (AHP) is adopted to develop the LCSA integration model. The minimum threshold limits of impact categories are evaluated and integrated into the proposed decision framework. Further, thematic and cross-sectional analyses are performed on the interview findings to rationalize the proposed decision framework. The findings include a detailed and customized project assessment framework, an integration model, and a decision framework for the assessment of different project alternatives. This study helps policy- and decision-makers in selecting the project alternative by maximizing sustainability in road infrastructure projects. Insights into environmental and social externalities and their quantitative interpretation throughout the life of the road are also achieved.

“…Due to the vast research performed with the aim to valorize slag, it is interesting to obtain a relationship between potential applications and slag clusters [18,19,29,30]. If this is performed for every possible application, a better valorization of each slag cluster can be obtained.…”

Classification of BOF Slag by Data Mining Techniques According to Chemical Composition

In the process of converting pig iron into steel, some co-products are generated—among which, basic oxygen furnace (BOF) slag is highlighted due to the great amount generated (about 126 kg of BOF slag per ton of steel grade). Great efforts have been made throughout the years toward finding an application to minimize the environmental impact and to increase sustainability while generating added value. Finding BOF slag valorization is difficult due to its heterogeneity, strength, and overall swallowing, which prevents its use in civil engineering projects. This work is focused on trying to resolve the heterogeneity issue. If many different types of steel are manufactured, then different types of slag could also be generated, and for each type of BOF slag, there is an adequate valorization option. Not all of the slag can be valorized, but it can be a tool for reducing the amount that must go to landfill and to minimize the environmental impact. An analysis by means of data mining techniques allows a classification of BOF slag to be obtained, and each one of these types has a better adjustment to certain valorization alternatives. In the plant used as an example of the application of these studies, eight different slag clusters were obtained, which were then linked to their different potential applications with the aim of increasing the amount valorized.

Social impact assessment (SIA) provides a methodology for defining, monitoring and employing measures to demonstrate the benefits and/or harms created for target communities through evidence of social outcomes and impacts. Although a recent increase in the number of applications is seen, SIA lacks consensus in its methodology, which increases ambiguity and complicates the generalization of any results obtained from individual studies. The objectives of this study are to investigate the methodology of SIA in order to define trends, state of the art, limitations, knowledge gaps, and to recommend future research directions. This study employs a systematic mapping to determine the methods available to perform SIA, and more importantly to identify a set of fundamental challenges faced by practitioners using SIA. Articles are searched through online databases, and are limited to the English language. A total of 81 articles published between 2009 and 2019 were selected, of which 49 included a case study application. A total of 12 fundamental challenges were identified, based upon the screened articles, which serve as a starting point for future research directions to further enhance the SIA methodology.
