Abstract

Purpose

The purposes of this study are to contribute to the limited green growth (GG) literature in emerging markets, to analyze GG from a financial economy perspective and to determine the contribution of financial development and innovation to GG in Brazil, Russian Federation, India, China and South Africa and Türkiye (BRICS-T). BRICS-T countries significantly impact the world population, international politics, energy resources and economy. In addition, BRICS-T countries are one of the leading countries in the world with their sustainability efforts. Investigating the GG model in these countries may contribute to structuring emerging economies around the principles of GG and advancing global green transformation efforts.

Design/methodology/approach

The authors applied panel data analysis from 2001 to 2019. GG is economic growth free from environmental depletion in the model. National income, personnel expenditure and foreign direct investments are macroeconomic variables. These variables measure economic development and promote economic and social progress, which is essential for GG. Capital accumulation and innovation are essential tools in GG transformation. Therefore, financial development and patent applications represent the moderating variables. The authors estimate the fixed effect model with Parks-Kmenta robust.

Findings

Empirical results show that national income growth and foreign direct investments positively affect GG. Personnel expenditure negatively affects GG. On the contrary, financial development and patent growth have little moderating role.

Originality/value

This study contributes to the literature on creating a GG model in emerging countries. The study is original in its model and sample.

The purpose of this study is to modify guar gum (GG) into guar gum acetate (GGA) and phthaloyl guar gum (PHGG) by transesterification and phthaloylation, respectively.

Abstract

Purpose

The purpose of this study is to modify guar gum (GG) into guar gum acetate (GGA) and phthaloyl guar gum (PHGG) by transesterification and phthaloylation, respectively.

Design/methodology/approach

GG has been modified into GGA through transesterification reaction between GG and vinyl acetate and PHGG through esterification reaction with phthalic anhydride. The modified GG was characterized by solubility test, Fourier-transform infra-red (FTIR) spectroscopy, proton nuclear magnetic resonance (1H NMR) spectroscopy, X-ray diffractometry (XRD) and thermogravimetric analysis. Swelling properties of GGA and PHGG hydrogels in water were evaluated.

Findings

These two types of modified GG have better solubility such as in dimethyl sulfoxide and N,N-dimethylformamide but no true organosolubility was achieved. The modifications were confirmed through FTIR with new absorption peaks at 1,733 cm−1 for GGA and 1,709 cm−1 for PHGG coupled with observed substitution peaks at 1.80 to 2.20 ppm and 7.40 to 7.90 ppm, respectively, from 1H NMR spectroscopies. XRD revealed both GGA and PHGG are less crystalline than native GG. GGA was found to be more thermally stable than native GG, whereas PHGG was slightly less thermally stable than native GG. The swelling property in distilled water for native GG, PHGG and GGA was 918.43 ± 46.62%, 537.04 ± 2.87% and 393.04 ± 13.42%, respectively.

Research limitations/implications

The GGA and PHGG hydrogels are expected to be useful for biomedical fields such as tissue engineering and drug-delivery.

Originality/value

Modifications of native GG into GGA using vinyl acetate and PHGG using phthalic anhydride are novel.

Abstract

Purpose

The purpose of this paper is to study the effect of acrylated guar gum (GG) compared with GG in acrylic emulsions with reference to its viscosity, film properties such as mechanical strength, weathering properties and clarity.

Design/methodology/approach

The acrylate derivatives were synthesised and characterised and then incorporated in acrylic emulsions and their rheology studied. Films were analysed for their clarity and mechanical properties. The films were then subjected to UV radiation and the influence of these additives on the weathering properties was studied.

Findings

The viscosity of acrylated GGs in emulsions was lower than that of GG in emulsion because of the increased hydrophobic nature and hence reduced water‐binding capacity. The mechanical properties of acrylated GGs were superior compared with GG due to increased compatibility of the additive with the polymer binder. This was further confirmed with increased clarity of the films. Acrylated GG was found to act as a protective additive with reference to UV degradation of the coatings.

Research limitations/implications

The performance of these additives was analysed on un‐pigmented coating formulations, which may not conform with pigmented coatings.

Practical implications

These biodegradable additives synthesised from renewable resources could be used to increase the mechanical strength as UV stabilisers and in some cases also as rheology modifiers.

Originality/value

The use of acrylated polysaccharides to increase mechanical and weathering properties allows the use of biodegradable, renewable resources as opposed to petroleum‐based compounds.

Abstract

Purpose

While sustainable growth extends the use of resources, it is crucial to explore green growth (GG) that ensures growth sustainability through the adoption of renewable energy. Thus, this study is motivated to investigate the influence of renewable energy on GG in 19 emerging countries spanning a decade and a half (2000–2020). This study aims to provide a quantitative examination of how renewable energy contributes to sustainable economic growth.

Design/methodology/approach

This study uses advanced dynamic common correlated effect techniques to assess the long-term effectiveness of renewable energy on GG. Additionally, it uses Dumitrescu and Hurlin causality tests to identify synchronicity between the respective variables.

Findings

The findings of this study reveal that the adoption and utilisation of renewable energy effectively promote GG in emerging economies. However, in contrast, the significantly greater negative influence of trade openness on GG compared to renewable energy highlights the inadequacy and limited impact of cleaner energy alone.

Originality/value

To the best of the authors’ knowledge, existing literature predominantly focuses on investigating the relationship between renewable energy and economic growth, with only a limited number of studies exploring the impact on GG. To the best of the authors’ knowledge, this study would be the first to analyse this relationship in these emerging countries. Furthermore, previous estimation frameworks used in prior studies often overlook the crucial factor of cross-sectional dependence (CSD) among countries. Therefore, this study addresses this issue using a contemporary econometric approach that deals not only with CSD but other biases, like endogeneity, autocorrelation, small sample bias, etc.

Abstract

Purpose

This study aims to investigation of the guar gum-manganese dioxide (GG/MnO2) nanocomposite (NC) synthesized using an environment-friendly method and the degradation of reactive yellow (RY 145) dye in the UV system.

Design/methodology/approach

Characterization of the GG/MnO2 NCs were conducted using field emission scanning electron microscopy, X-ray diffraction and Fourier-transform infrared spectroscopy. Experiments were conducted using a 1 L glass reactor coupled with Ultraviolet (UV-C) blue light bulb of wavelength 250 nm and power of 8 W.

Findings

The NC (2.25 g/L) displayed high RY 145 dye degradation (81%) with 10 mg/L of concentration at pH 3. The coefficient of determination (R2 0.99) also depicted that the model fits the experimental data. The analysis of variance (ANOVA) showed that the F-values of 464.75, 276.04 and 5.15 are related to the dose of GG/MnO2 NCs, initial concentration of RY 145 dye and solution pH, respectively.

Practical implications

The GG/MnO2 NCs followed by photo oxidation process (UV-process) could be used to degrade the RY 145 dye from synthetic wastewater.

Originality/value

There are two main innovations. One is that the novel process is performed successfully for RY 145 dye degradation. The other is that the optimized conditions are obtained by Box–Behnken design. Also, the effects of different variables on the RY 145 dye removal efficiency were investigated.

Abstract

Purpose

Guar Gum (GG) is used in Shale oil exploration. Excessive price increase in the Guar futures market had a spillover impact on Guar spot prices and affected Guar export from India as Shale oil producers started exploring alternate sources. In this paper, the role of excessive speculation in the futures market, and its adverse impact on the guar-based agri-business ecosystem have been empirically explored.

Design/methodology/approach

Volatility spillover dynamics between WTI crude oil and Guar futures have been explored using bivariate-Granger Causality, BEKK–GARCH models with Wavelet multi-resolution analysis. The wavelet-based models capture the multi-scale features of mean and volatility spillover to identify the effect of heterogenous investment behavior in the time and frequency domain.

Findings

The results provide evidence that excessive speculation in futures markets increases spot market volatility. The results also suggest that the excess presence of short-term investors can destabilize the futures market.

Research limitations/implications

The purpose of the commodity futures market is to support price discovery and risk management. However, speculative practices can destabilize these purposes leading to the failure of the business ecosystem.

Originality/value

The novelty of this paper is twofold. First, it explores the economic linkages between the spot and futures market and tests whether the presence of heterogeneous traders affects the economic linkages. Second, it models the impact of short-term speculative investment on the destabilization of the spot market.

Abstract

Purpose

The rising dominance of sustainable development (SD) and green growth (GG) in contemporary societies have become one of the foremost sources of contentions that most states face today in the developing world. It is often suggested that institutionalizing key policies of the SD and GG present a win-win situation. The purpose of this paper is to scrutinize and evaluate such a debate in the light of existing empirical evidence on SD, GG and economic development (ED). It seeks to answer the question “does the sustainability discourse fit in the modern socioeconomic needs of the developing nations or not.”

Design/methodology/approach

This paper adopts a qualitative research technique. It mainly relies on secondary sources of data. In aligning with key technical approach of qualitative research; the secondary sourced data were also subject to content and thematic analyses from which facts, and assumptions were derived to undertake the present study.

Findings

The main verdict of the paper is that SD and GG discourses do not fit in the crucial socioeconomic needs of the underdeveloped nations. Endorsing SD and GG policies in emerging countries is essentially about restraining their economic prosperity. In fact, it is an anti-growth agenda in its essence. What makes it anti-growth is the core element of minimal use of critical natural capital to grow economically, which lies at the heart of entire SD and GG. What makes it hard for the emerging nations to comply with core elements of the sustainability is their capacity to comply with alternative growth pathways. Thus, limiting the growth process by promoting the agendas of SD is fundamentally about keeping deprived state/people poor.

Research limitations/implications

The work is exclusively limited to the author’s understanding of issues and key concerns of developing world concerning institutionalization of the SD and GG. The author’s comprehension may not fully reflect the foremost concerns of the emerging nations. Moreover, Just a single research approach was employed in this study. A further empirical investigation is required in this field for acknowledging and documenting all the key motives and perspectives of third-world states when endorsing SD and GG policies.

Originality/value

The paper sheds light on the political aspects of promoting the SD, and the long-lasting fact that the key concerns of sustainability pose challenges to the very existence poor states in the south. Most of them are highly exposed to socioeconomic shocks. They cannot afford to implement the policies of SD and GG as the majority of their citizens are living under poverty line. The only panacea they have to overcome the existing social deprivation is the massive ED. Furthermore, institutionalizing SD and GG may cause societal clashes in the poor states.

Abstract

The Pacific Island countries are culturally diverse, politically challenging, extremely vulnerable to climate change and natural disaster impacts, and financially heavily dependent on aid flows. This chapter examines barriers and opportunities for Green growth (GG) to flourish in a country with a practically non-existent real economy and which is currently under the threat of disappearance under water. It draws on a visiting experience and lessons from the literature and tries to investigate the role of innovation and entrepreneurship as poles of re-birth and local creativity. More particularly, I here discuss why a least developed country such as Kiribati might be the perfect location for dynamics of GG to get born and how, Kiribati, a country under threat and fear, can be transformed into a lighthouse of entrepreneurship which can give boost to the implementation of one of the most advanced energy technologies in the world. I also discuss how, ultimately, a “least developed economy” can secure scientific lessons, which are highly significant for the international knowledge society.

Abstract

Purpose

We examine collective responses to identity threats in organizations, conceptualizing these responses as identity contests in which members of opposing groups share an identity and strive to protect the social psychological rewards derived from that identity.

Methodology/approach

We present an argument for the importance of identity as a basis for motivation, suggesting that the desires to obtain and protect identity rewards underlie much behavior in organizations. We also present two case studies from which we derive further theoretical implications about identity contests as drivers of organizational change.

Findings

Our case studies show how organizational subgroups perceived identity threats arising from actual or proposed changes in policies and practices, mobilized to resist these threats, and negotiated further changes in organizational structure, policies, and practices.

Practical implications

Applying this analysis, social psychologists who study identity threats can see how responses to such threats are not solely individual and cognitive but sometimes collective and behavioral, leading to changes in organizations and in the surrounding culture.

Social implications

Our analysis of how identity contests arise and unfold can enrich understandings of how self-definition and mental well-being are shaped by organizational life.

Originality/value

By focusing on collective responses to identity threats, we offer a new way of seeing how intra-organizational identity struggles are implicated in social change.

Abstract

Purpose

The purpose of this paper is to evaluate the efficiency of acrylated guar gum (AGG) as an additive in alkyd resin for improved mechanical properties and to optimize the results of such an addition.

Design/methodology/approach

For studying the effect of AGG on coating properties, guar gum was modified to various degrees of esterification and various compositions of alkyd systems were made by incorporating different concentrations of AGG. The mechanical and solvent absorption of the unmodified and modified alkyd systems were characterized.

Findings

The incorporation of AGG into alkyd coating showed significant improvement of mechanical properties over the unmodified one. The modification caused an additional crosslink site through its unsaturation which led to increased crosslink density without phase separation of additive from the alkyd system which was confirmed by SEM scans.

Research limitations/implications

The reactive additive, AGG used in the present study was synthesised using acryloyl chloride. Besides, it could also be synthesised from methacryloyl chloride and the effect of methyl substitution on water and solvent absorption could be studied.

Practical implications

The method developed provided a simple and practical solution to improving the mechanical properties of alkyd coatings.

Originality/value

The method for enhancing mechanical properties of cured alkyd system was novel and could find numerous applications in surface coatings.
