Abstract

Corporate environmental disclosure has been increasing steadily as it is an essential factor for sustainable development. However, this factor seems to be insufficientl recognised within the Nigerian corporate world. The objective of this study is to assess the level of corporate sustainability disclosures in environmentally sensitive industries in Nigeria. This study is based on secondary data obtained from annual reports of firms listed on the Nigerian Exchange Group (NGX). Data used were collected from 45 sampled companies listed under 6 environmentally sensitive sectors for the 2021 financial year. Content analysis was applied to measure the level of environmental disclosures. The Environmental Disclosure Index (EDI) was prepared based on the Global Reporting Initiative (GRI) Standards. This research used independent sample t-test, analysis of variance, and the Kruskal-Wallis test as techniques of analysis. There were statistically significant differences in firms’ disclosure levels based on environmental certifications. The agriculture industry made the highest environmental disclosure, whereas the companies in the natural resources industry disclosed the least. It was found that companies revealed maximum information on their energy and environmental compliance initiatives, while there was inadequate information in other areas of environmental disclosure, such as neko77 supplier environmental assessment, effluents and wastes, and materials. The study provides implications for the strict adoption of a systematic reporting framework, especially for environmentally sensitive firms, while offering insights to guide policymakers, regulatory bodies, industry associations, and businesses in Nigeria to promote transparency and responsible environmental reporting.

Abstract

Switching from conventional fossil fuel vehicles to electric vehicles (EVs) offers a promising way to reduce carbon emissions, especially if we also decarbonize our electricity sources. This study focuses on Dushanbe, the capital of Tajikistan, where EV adoption is still in its early stages. Understanding local perceptions is crucial for making informed decisions to promote the use of EVs. There has been used a qualitative approach, gathering data through questionnaires from a diverse group of Dushanbe residents. The analysis showed varied perceptions as older respondents were more likely to agree with EV adoption, and there were notable differences based on gender and education level. Women showed greater enthusiasm for EVs, and those with a Master’s degree were more likely to support the transition. Residents recommended increasing salaries, improving infrastructure, and providing government support to make the shift to EVs easier. This study highlights the importance of understanding local views in shaping policies for sustainable transportation in Dushanbe. Further research and targeted actions are needed to overcome challenges and encourage widespread EV adoption.

Abstract

The impact of crude oil contamination on the environment, especially on soil quality, has been a major concern in Nigeria and for regulatory bodies worldwide. This study focused on assessing the phytoremediation potential of two plant species T. spathecea and P.balfouriana, grown on crude oil-contaminated soils. The plant were cultivated in soils polluted with crude oil at concentrations of 0, 50, 100, 150 and 200 mL/kg. The research was laid out in a 5 x 5 factorial experiment with three replicates, in a completely randomized designed to give a total of 75 experimental units. The gas chromatographic flame ionization detector (GC-FID) was used in determining the total petroleum hydrocarbon (TPH), the atomic absorption spectrophotometer (AAS) was used to determine the heavy metals. The relevant analytical techniques of APHA and AOAC (2020) was used to determine the phytochemical contents of the plant species. The results of TPH analysis revealed that the concentration of TPH increased with the rising concentration of crude oil pollutant in the soil. TPH values were 1,120 mg/kg for P. balfouriana and 2,762.79 mg/kg for T. spathecea. Both plant species showed considerable growth despite increasing crude oil concentrations. The results of heavy metals phytoextraction indicated a trend of increasing metal concentrations with increasing crude oil pollution. Copper concentration ranged from 2.28 mg/kg in T. spathecea to 12.64 mg/kg in R. simplex. Iron uptake ranged from 11.36 mg/kg in P. balfouriana to 22.40 mg/kg T. spathcea. The uptake of manganese increased from 5.56 mg/kg in P. balfouriana to 10.56 gm/kg in T. spathecea, while cobalt concentration decreased from 0.08 mg/kg in T. spathecea to 0.04 mg/kg in P. balfouriana. The study highlights the potential of P. balfouriana and T. spathecea for phytoremediation in crude-contaminated soils and advocates for their use as effective tools for soil remediation.

Abstract

The increasing number of batik industries in Indonesia may lead to water pollution due to wastewater containing high levels of organic pollutants. This study evaluated advanced oxidation processes (AOPs) utilising H2O2/UV to decolourise and remove organic contaminants (measured as chemical oxygen demand, COD) from batik wastewater. The study aims to compare the effectiveness of adding ferrous and persulfate as catalysts as catalyst in the H2O2/UV process, specifically evaluating the H2O2/Fe2+/UV and H2O2/S2O82-/UV processes. The results indicated that all treatment methods effectively decolourised and degraded COD in the batik wastewater. COD and colour removal achieved up to 96.51% and 78.70% for H2O2/UV, 97.20% and 83.53% for H2O2/Fe2+/UV, and 97.20% and 83.53% for H2O2/ S2O82-/UV, processes, respectively. Additionally, the use of persulfate as a catalyst accelerated the oxidation processes, reaching completion in 45 minutes compared to 60 minutes with the other catalyst.

Abstract

This study was necessitated as a result of the frequent cases of diarrhoea observed among the students of the researcher. The researcher employed faecal indicator bacteria to assess the impact of the infiltration layer and seasonal variations on groundwater contamination from pit latrines in the municipalities where the students reside. The main experimental materials consisted of water samples collected from 15 randomly selected wells in the Tano Districts of Ghana. Total coliforms, faecal coliforms, and enterococci were used as faecal indicators. The Most Probable Number (MPN) method was employed to determine the presence of faecal indicators in the water samples. The results showed that enterococci and faecal coliforms were reliable indicators of human faecal contamination than total coliforms. The study revealed that coliform level (indicating pit latrine groundwater contamination) increased with greater pit depth and lower static water levels. Based on these findings, it is recommended that the future studies on human faecal contamination prioritize enterococci and faecal coliforms over total coliforms as indicators. To mitigate groundwater contamination from pit latrines, the equation EC = 0.12(PLD) – 0.09(SWL) + 2.37 can be applied to predict a safer infiltration layer between the bottom of pit latrines and the water table.

Abstract

Power transformers face significant aging issues, which threatens their reliability and service life. This research aims to develop an accurate method for predicting the remaining lifespan of transformers. Current studies highlight the inadequacy of existing approaches in determining transformer lifespan, which is affecred by the degradation of paper insulation through furan compounds and hotspot temperatures. This method adheres to the CIGRE D1 738 (2018) standard, which converts furan concentration into Degree of Polymerization (DPest) as an indicator of paper insulation condition. The methodology involves analyzing oil test data and operational temperature to estimate the remaining life of the transformer. This research not only aims to improve the accuracy of paper insulation assessments but also integrates sustainability principles. The goal is to optimize the use of existing transformers, reduce premature replacements, and conserve material and energy resources. By minimizing unexpected failures, this research contributes to reducing industrial waste and environmental impact. Furthermore, this approach aligns with practices that support economic and social sustainability. Extending the lifespan of critical devices can lower maintenance costs while ensuring a reliable and sustainable energy supply. The proposed method provides a comprehensive framework for predicting transformers longevity.

Abstract

In recent years, fabric waste has become an important sustainability issue that raises concerns and attracts attention from stakeholders in the fashion industries and the media. Over the past 15 years, the production and consumption of clothing have increased substantially, driven by the rise of demand for fashionable style and the proliferation of fast fashion. This study explores the fabric waste generated by the garment operators within the Kumasi metropolis. A qualitative research design, guided by a phenomenological approach was employed. Data were collected from six zones using purposive sampling technique to select respondents. Interviews and observations served as the primary data collection methods, and data were analysed thematically using NVIVO software. The findings reveal that the use of single-ply and bulk-ply cutting techniques in garments construction led to the generation of tons of fabric waste, particularly among small-scale garment producers. It is recommended that garment operators adopt effective strategies for reusing and responsibly disposing of fabric waste. Furthermore, the use of biodegradable fabrics is encouraged, as they have a lower environmental impact.

Abstract

Shoreline mapping plays an important role in sustainable coastal management, particularly in strategic areas such as the Kedungsepur Metropolitan Area. This study aims to analyzes shoreline changes and identifies their impact on coastal communities. Shoreline extraction was conducted using remote sensing data from Landsat satellite imagery, while the analysis of shoreline changes was performed using the Digital Shoreline Analysis System (DSAS) within a Geographic Information System (GIS) environment. The results reveal that shoreline changes – both erosion and accretion – occurred across Kendal Regency, Semarang City, and Demak Regency. The most severe coastal erosion was identified in Bedono Village (Demak Regency), while the highest accretion occurred in Pidodo Kulon Village (Kendal Regency). When analyzed by watershed units, the highest accretion was found in the Bodri Watershed, one of the priority areas for revitalization. These findings highlight the need for integrated policy approaches that connect coastal and watershed management to ensure long-term sustainability.

Abstract

In many parts of sub-Saharan Africa, grid-connected electricity is unreliable and frequently unavailable in rural locations. Alternative electricity-generation fossil-fuel sources are prohibitive. Solar energy photovoltaic systems have great potential in bridging the energy gap in electricity off-grid locations in sub-Saharan Africa and contribute to the region’s energy portfolio at utility and/or domestic levels. Most installed PV systems in sub-Saharan Africa have often not achieved their anticipated functionality and/or fail frequently. Take-up of PV systems consequently remains low, with long pay-back times. In this study, we have investigated the barriers and challenges associated with PV system operation and probable causes of failure of installed systems within the sub-Saharan Africa region from the perspective of technical stakeholders. We undertook a broad consultation of technicians (installers), engineers, project supervisors, and other technical stakeholders via questionnaires and interviews in a typical sub-Saharan African setting, namely Ghana. Our results show that component quality, cost, availability, and customer preferences are dominant factors considered by the technical stakeholders in component selection during the planning and execution of PV projects. The survey analysis revealed that inverters and batteries are components that account for the most malfunctioning and failures in installed PV systems, while PV panels account for the least. Low product quality, user errors, natural/environmental incidents, and poor sizing/installation errors are identified as key causes of components’ failure.
