The purpose of this study is to investigate the effects of resource use and environmental innovation on firms’ financial costs.

The sample consists of 2,588 firm-year observations from 647 companies collected from Thomson Reuters over a five-year period (year 2014 to year 2018). The authors analyze the data using panel-corrected standard errors, which corrects heteroskedasticity issues and contemporaneous error in the data. Further, the authors adopt cluster analysis based on the year and industry. The authors also adopt the generalized method of moments and two-stage least squares regression to check for endogeneity issues and validate the findings.

The findings generally indicate that resource use is negatively associated with firms’ cost of capital. Firms’ engagement with operational activities improves savings in the usage of resources, but environmental innovation is found to be positively associated with the cost of capital. This may be attributable to higher capital investment, stringent risk assessment and third-party assurance associated with firms’ environmental innovation.

The findings urge regulators, practitioners and stakeholders to engage in more dialogues to reduce the costs associated with environmental sustainability innovation. This may be in the form of new technologies, energy-saving products, waste recycling and green innovations. Government intervention via greater infrastructure, tax incentives and regulatory reform may support the growth of innovation in emerging market economies.

Efforts are needed to encourage a dynamic, innovative and entrepreneurial mindset among the people living in emerging countries. Also, government regulatory reform is imperative in encouraging innovations in the environmental, social and governance ecosystem.

The effect on society would be in the form of a new product innovation that creates better living standards and environments for the communities.

To the best of the authors’ knowledge, this is one of the few studies that focuses on the impact of firms’ resource use and environmental innovativeness and its implications on business financial costs in both emerging and developed markets.

Ensuring energy security and controlling the share of energy in climate change are the two main challenges of the energy sector in the path of a sustainable future. This study has designed the dynamic model of Iran’s electrical energy supply system based on the water-food-energy-climate change nexus in order to identify sustainable policies for the supply of electrical energy resources and adaptation to Iran’s climate change process.

For this purpose, first, the system dynamics model was designed with the participation of policymakers and the supply and demand data of water-food-energy resources and the trend of climate change and economic growth in Iran. After validation, the model is simulated in the 30-year horizon (2020–2050), and according to the results of the Monte Carlo sensitivity analysis, Iran’s electric energy supply policies are based on four strategies, including (1) Electric energy supply based on electric energy supply management from non-renewable sources, (2) Development of electrical energy supply based on management of energy supply from renewable sources, (3) Electrical energy supply based on electrical energy demand management and (4) Electrical energy supply based on adaptation to climate changes. By identifying and applying the policies of each strategy separately, the model was tested and the results were compared.

Based on the implementation of the combination of selected policies in the model, the following policies have been proposed: 16% development of nuclear power plants, 18% reduction in the ratio of production of gas power plants to the total production of non-renewable power plants, and an increase in the production of combined cycle power plants through conversion of gas to combined cycle, energy aggregation and development of heat recovery systems in industrial units by 32%, a decrease of 5% Energy transmission and distribution losses, per capita reduction of energy consumption from 0.926 to the global average of 0.182 (MW) per year, management of water demand in the food sector by increasing irrigation efficiency to about 85%, a 27% increase in the area of land under the irrigation network, and reducing losses Food amounting to the global average of 0.9 m tons per year.

The proposed model is an application of system dynamics in the field of policymaking to ensure the security of electrical energy resources, taking into account the water-food-energy-climate changes nexus. The model is a valuable tool for policymakers in planning the sustainable management of resources in the path of adapting to climate change.

The purpose of this paper is to clarify the conceptual confusion in the extant literature about organizational agility and explore its role in different relationships in the context of digital transformation.

An integrative review of the relevant literature on agility was conducted. The literature on organizational agility and other variables in recent quantitative research was also examined to explore its role in different relationships.

Organizational agility is the ability to quickly respond and proactively embrace unanticipated changes in dynamic environments through effective resource reconfiguration and rapid decision-making. The role of organizational agility in achieving digital transformation has not been addressed from a holistic conceptual perspective. This paper addresses that gap and proposes that organizational agility is the underlying mechanism for an organization to fully use and engage its workforce, operation and network in the process of digital transformation.

This research is an integrative review of the existing literature on the concept of agility and its relationships. The next phase of research needed for theory building will be the operationalization of constructs.

Organizations should strive to strategically develop both the reactivity and proactivity sides of organizational agility in achieving digital transformation that involves fundamental changes at different levels of the organization.

This paper explores the role of organizational agility in digital transformation through an integrative review of the relevant literature.

Sadaqah, a form of Islamic charity, was widely used to mitigate the adverse consequences of the COVID-19 pandemic on people’s socio-economic conditions and well-being. However, the extent to which Sadaqah served the intended purpose remains unclear. Therefore, this study aims to explore the perceived effects of Sadaqah on the situational poverty and well-being of tertiary education students in Malaysia during the pandemic. The findings of this study could provide valuable insights into whether and how Sadaqah can address situational poverty and well-being challenges during COVID-19-type emergencies.

This study surveyed students at three Islamic universities in Malaysia. A total of 288 complete and valid responses were collected and analysed. The study used the Kruskal Wallis test to examine the relationship between students’ socioeconomic status and their odds of receiving Sadaqah. The chi-square test was used to estimate Sadaqah’s perceived effect on students’ well-being. The repeated measure analysis of variance was used to examine the effect of Sadaqah on the situational poverty and well-being of the respondents.

The pandemic starkly magnified the situational poverty of students from underprivileged backgrounds and the well-being struggles of those from high-income households. Many students reported pandemic-induced financial and physical well-being issues, including difficulties meeting medical and food expenses. This underscores the pressing need for comprehensive support. However, the Sadaqah received by the students did not cover essential expenses such as rent, tuition and medical bills. This lack of comprehensive support could be a critical factor in Sadaqah’s limited impact on addressing situational poverty and enhancing the well-being of the students.

This study revealed Sadaqah’s limitations in addressing situational poverty during COVID-19-type emergencies and identified promising avenues for improvement. The findings underscore the need for a more comprehensive approach to Sadaqah, which could significantly enhance the well-being of its recipients. This insight could potentially inform policy and practice, inspiring hope for a more effective approach in the future.

As lubricating oils are used, their performance deteriorates and they become contaminated. The purpose of this paper is to investigate the lubrication performance of reclaimed 5 W-30 a fully synthetic used engine oil (UEO) with wear tests after refining it from a solvent-based extraction method using solvent (1-PrOH) and adsorbent materials such as cement, celite and deep eutectic solvent (DES).

The treated oil mixtures were prepared by blending engine oils with various adsorbent materials at 5% (w/w) in organic 1-PrOH solvent at a UEO: solvent ratio of 1:2 (w/w). The measurement of kinematic viscosity, density, the total acid number (TAN) and elemental analysis of oil samples was done by the ASTM standards D445/D446, D4052, D974 and D6595, respectively. Adsorbents and treated oil samples characterized by SEM-EDX, FTIR and UV analysis, respectively. Meanwhile, lubricating performance in tribological applications was evaluated through the wear test device using a rotating steel alloy 1.2379 cylinder and a stationary 1.2738 pin under 20, 40 and 80 kg load conditions. Worn surface analysis was done with SEM and 2.5D images.

It was found that when using the combination of cement and celite as an adsorbent in the reclamation of used engine oil demonstrated better lubricant properties. The properties of used engine oil were improved in the manner of kinematic viscosity of 32.55 from 68.49 mm²/s, VI (Viscosity index) value of 154 from 130, TAN of 3.18 from 4.35 (mgKOH/g) and Fe content of 11 from 32 mg/L. The anti-wear properties of used engine oil improved by at least 32% when 5% cement and 5% celite adsorbent materials were used together.

The paper is based on findings from a fully synthetic 5 W-30 A5 multi-grade engine lubrication oil collected after driving approximately 12.000 km.

The results are significant, as they suggest practical regeneration of used engine oil is achievable. Additionally, blending fresh oil with reclaimed used engine oil in a 1:1 ratio reduced wear loss by over 10% compared to fresh oil.

Reusing used engine oils can reduce their environmental impact and bring economic benefits.

This study showed that the properties of UEO can be enhanced using the solvent extraction-adsorption method. Furthermore, the study provided valuable insights into the metal concentrations in engine oil samples and their impact on lubrication performance. The order of the number of the grooves quantity and the possibility of the observed scuffing region trend relative to the samples was UEO > 5W-30 fresh oil > Treated oil sample with the adsorbent cement and celite together.
