Sustainable Photovoltaics: Optimising Material Consumption, Cost and Environmental Performance Through Smart Sustainability Approaches for Crystalline Silicon Solar Photovoltaics

Solar RRL, Volume 10, Issue 11, 15 June 2026.
A sustainability framework shows that photovoltaics can simultaneously improve material security, reduce costs, and improve environmental performance. Updated learning curves reveal declining material intensity and emissions alongside rising energy return on investment, EROI (> 25).

An Evaluation of Revegetation Success on Bauxite Residue [PDF]

Restoration Ecology, 2009
AbstractThe current study was undertaken to evaluate the success of a revegetation program on three sites within the Bauxite Residue Disposal Area at the Aughinish Alumina Ltd. refinery. This was achieved by determining botanical diversity, substrate conditions, and plant uptake.

Alkali Recovery of Bauxite Residue by Calcification

Minerals, 2022
Bauxite residue (red mud) generated during alumina production is a highly alkaline solid waste. The red mud is mainly stored on land, but it can cause harm to the surrounding environment and human health. The transformation of red mud into soil is a feasible method for the large-scale disposal of red mud, but alkali removal is the key process that ...

Enhancing solidification in one-part geopolymer systems through alkali-thermal activation of bauxite residue and silica fume integration

Case Studies in Construction Materials
This work describes the synthesis of geopolymers, a family of amorphous alumino-silicates, employing Silica fume and bauxite waste as precursor materials in an alkali-activated polycondensation reaction and the investigation of their properties.

Sintering Behavior of Red Mud Compact [PDF]

, 2008
It is beyond doubt that activity of primary industries often yields substantial amounts of byproducts. The disposal in the original industrial site is favoured by economic reasons though traditional storage in nearby dumps can be impractical owing to the

Microbially generated ferruginous crusts: A potential biosignature of continental input in coastal settings

Sedimentology, Volume 73, Issue 4, Page 1225-1243, June 2026.
ABSTRACT Thin ferruginous sandy crusts are common on top of sandstone beds in the Early Permian post‐glacial deposits of the Paraná Basin in southern Brazil. These crusts usually preserve wrinkle structures, suggesting that they might be a product of microbial mediation.

Full Analysis of Sierra Leone Bauxite and Possibilities of Bauxite Residue Filtration

Journal of Siberian Federal University. Engineering & Technologies, 2016
Chemical analysis, classical or instrumental using ICP and the XRF spectrometry, offers complete information on elemental composition and major chemical constituents of bauxite and bauxite residues resulted from the Bayer process. The XRD diffractometric analysis provides information on quantitative mineralogical composition of these materials and it ...

Raman Spectroscopic Identification of Oxide Phases in a Corroded MgO–Steel Composite Anode Used in Aluminum Molten Salt Electrolysis

Advanced Engineering Materials, Volume 28, Issue 10, 20 May 2026.
Micro‐Raman spectroscopy is applied to characterize corrosion products in a recycled‐based MgO–316L steel composite anode after molten salt electrolysis. A depth‐dependent Fe–O/Fe–Al–O layer sequence of magnetite, hercynite, and an Al‐doped magnetite transition zone is identified.
