Abstract: Synthetic dyes, particularly azo dyes, pose significant environmental and health risks due to their persistence, toxicity, and potential carcinogenicity. Zinc oxide (ZnO) is a promising photocatalyst for wastewater remediation, but its wide bandgap and rapid charge recombination limit its practical efficacy. Furthermore, conventional doping methods often rely on hazardous chemical precursors, undermining the sustainability of... More

Abstract: This paper deals with carbon emissions reduction through building material selection in housing construction using Analytical Hierarchy Process (AHP) method. Drawing on the concept of Sustainable Development in the Environment (SDE), inadequate selection of building materials makes a significant contribution to carbon emissions. The achievability of the goal of SDE is in rethinking Locally Sourced... More

Abstract: Evaluating rock mass quality using three-dimensional (3D) point clouds is crucial for discontinuity extraction and is widely applied in various industrial sectors. However, the utilization of this method in geological surveys remains limited. Notable limitations of current research include the scarcity of validation using simple geometric shapes for discontinuity extraction methods, and the lack of... More

Abstract: Water quality is fundamental to water security, ecosystem integrity, and public health. This study assessed the impact of wastewater effluent on the Trichardspruit River, which receives effluent from two wastewater treatment works (WWTWs). Over a 12-month period, water samples were collected across six study sites (S1–S6) to evaluate physicochemical and microbiological parameters relative to national... More

Abstract: Urban Heat Islands (UHI) are a significant environmental challenge in rapidly urbanizing cities, exacerbated by climate change and urbanization. The UHI effect causes the high temperatures of urban regions, causing high energy consumption, health hazards, and degradation of the environment. Remote sensing technology has found it invaluable to monitor and control UHI because it has... More

Abstract: The circular economy is an innovative concept of both production and consumption. It can reduce wastage, preserve resources, and minimize environmental effects with the help of recycling, recovering resources, and extending the life of products. It works as a pathway to reduce environmental footprints by redesigning production-consumption systems. This review critically examines global circular economy strategies, policy... More
