Hexavalent chromium (Cr(VI)) is a carcinogenic pollutant commonly found in wastewater from tanning and electroplating industries. This study investigates the efficiency of raw Cordia africana sawdust as a biosorbent for Cr(VI) removal. Batch adsorption experiments were conducted by varying pH (3-8), contact time (10-120 min), and Cr(VI) concentration (21-47 mg/L) using Response Surface Methodology (RSM) with Box-Behnken design. Characterization was performed using FTIR, SEM, BET, pH, and PZC analysis before and aft [...]

This study investigated the use of new bioadsorbent the Hydroxyfluorapatite (Ca10(PO4)6OH1.75F0.25, HFA) to eliminate Alizarin Red S (ARS), a harmful water pollutant. Initial batch tests were conducted to evaluate the adsorption process, focusing on both kinetics and equilibrium behavior. Various kinetic models were applied such as: pseudo first-order, pseudo second order, the intraparticular diffuision model and external diffusion model. The modeling results proved that the pseudo-second-order model best matched t [...]

Mediterranean regions like West Mani, Greece, face escalating water scarcity exacerbated by climate variability and seasonal tourism peaks, straining the water-energy-food (WEF) nexus. Olive cultivation, central to the region’s economy and culture, generates substantial underutilized biomass residues that increase wildfire risk if left unmanaged. At the same time, water supply increasingly relies on energy-intensive desalination and pumping. This study addresses the gap in integrated, place-based WEF nexus applicat [...]

Sindh Province, Pakistan, is highly vulnerable to hydroclimatic extremes, necessitating a detailed understanding of its precipitation patterns for effective water management. This study assesses spatiotemporal precipitation dynamics across Sindh from 2001 to 2024 by integrating satellite-based CHIRPS data, in situ observations from the Climate Knowledge Portal (CKP), and CMIP6 climate model projections. Validation results show strong agreement between CHIRPS and ground data (R ≈ 0.87, d ≈ 0.93), confirming the sate [...]

Characterizing drought severity using GRACE and TerraClimate datasets is globally important because it enables consistent, large-scale monitoring of both surface and subsurface water availability across data-scarce regions. This integrated perspective supports improved drought assessment, climate change impact analysis, and informed water-resource management worldwide. The Ethiopian Rift Valley has experienced recurrent hydrological drought hazards, posing serious threats to water availability, agricultural product [...]

Buildings account for a significant portion of global energy consumption, estimated at 30-40%, and also contribute to greenhouse gas emissions. Energy consumption in a building is mainly thermal (natural gas) and electrical. This energy is usually used for heating water, cooking, illumination, ventilation and air conditioning, powering appliances, floor heating, and other activities. These activities were examined, and their substitution by solar-based energy sources was reviewed. To achieve this objective, an exte [...]

The rising concerns of soil erosion, organic waste generation and global warming have shown the need to address them through multifaceted methods that transcend conventional linear models of resource utilization. Circular economy is a regenerative model that is anchored on caring about waste valorisation, resource effectiveness and environmental fortitude. In this paradigm, biochar has been developed as a multifunctional compound capable of integrating waste management, soil rehabilitation, climate control and rene [...]

The development and utilization of pharmaceuticals, notably antiretrovirals (ARVs), have significantly enhanced both human quality of life and life expectancy. Nevertheless, the excretion of these compounds into aquatic environments, often exacerbated by inadequate sanitation infrastructure, poses considerable risks to biota. This investigation evaluated the environmental impact of 14 ARVs consumed within the municipality of Belo Horizonte (BH), Brazil. The assessment employed the Environmental Risk Assessment (ERA [...]

The rising pollution levels in congested urban areas pose a serious threat to human health. Many solutions have been proposed to control and reduce gas emissions from road traffic, with results that are not entirely satisfactory. The adoption of new techniques and methodologies for early detection of pollutant emissions may enable effective management and control of road traffic contamination. The proposed method introduces an interactive protocol that facilitates communication between the traffic control center an [...]
