Bioprospects of Tree Species in Bioremediation of Bauxite Residue
, 2023 Red mud or bauxite residue is a highly alkaline toxic by-product that is generated during the production of aluminum by Bayer’s process. Around 1.5 tons of bauxite residues are produced for generating 1 ton of alumina.

Austral Ecology, Volume 51, Issue 9, September 2026.ABSTRACT Tropical freshwater systems host diverse and functionally important zooplankton communities that are increasingly threatened by multiple stressors. Here, we assessed how land‐use disturbance, local environmental conditions and macrophyte structure influence zooplankton richness, abundance and composition in Amazonian ponds and streams.

Modelling hydrological performance of a bauxite residue profile for deposition management of a storage facility [PDF]
, 2020 Accurate scheduling of bauxite residue (red mud) deposition time is required in order to prevent the risk of storage facility failure. This study was conducted to precisely determine the hydraulic parameters of bauxite residue and investigate the ...

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.ABSTRACT Geopolymer binders have emerged as promising alternatives to calcium aluminate cement (CAC) for refractory castables, although their thermomechanical behavior during heating remains poorly understood. This work investigates high‐alumina refractory castables bonded with geopolymers produced from metakaolin (MK), calcined kaolin (CC), and an ...

The Impact of Russia–Ukraine War in Maritime Data
The World Economy, Volume 49, Issue 9, Page 1907-1923, September 2026.ABSTRACT This study analyses weekly port calls from 2019 to 2026 to evaluate the Russia–Ukraine war's impact on maritime trade. The data reveals clear structural shifts that Ukrainian traffic moved from high‐risk areas like Odesa to safer Danube River ports.

Replacement of Sand with Bauxite Mining Waste in Concrete Production
Journal of Materials and Engineering Structures, 2019 The use of natural sand as fine aggregate in concrete is becoming problematic due to scarcity and pressure on mining of the resource. Alternate sources such as the use of industrial waste as replacement of natural sand in concrete are gaining popularity ...
