Department of Civil Engineering , University of Engineering and Technology Peshawar, Peshawar, Pakistan.
For millennia mud has been utilized to make brick for the construction of both residential as well as architectural purposes. However, concerns regarding their vulnerability to different kinds of hazards due to their weak mechanical properties and durability have emerged. This study addressed the global challenge of developing sustainable and affordable construction materials, particularly in resource-constrained regions.

Red mud (RM), an iron oxide-rich solid waste, shows potential as a catalyst for selective catalytic reduction in denitrification processes. This study investigates the catalytic performance and mechanism of metal-modified RM in reducing NO from diesel vehicle exhaust. Acid-washed RM catalysts were impregnated with varying ratios of cerium (Ce) and zirconium (Zr).

With the expansion of the mining industry, environmental pollution from microelements (MP) and red mud (RM) has become a pressing issue. While bioremediation offers a cost-effective and sustainable solution, plant growth in these polluted environments remains difficult. is one of the few plants capable of surviving in RM-affected soils.

This study presents a novel FeO/C composite material synthesized from red mud through a process of magnetic roasting and separation. The research explores the impact of FeO/C dosages, sodium persulfate (PS) concentrations, and initial solution pH on the chemical oxygen demand (COD) removal efficiency using Acid Orange 7 as a model pollutant. Optimal conditions were identified as 3 g/L FeO/C, 20 mM PS, and an initial pH of 2, achieving a 94.

College of Materials Science and Engineering, Guilin University of Technology, Guilin 541004, China.
This study is the first to convert two waste materials, waste rice noodles (WRN) and red mud (RM), into a low-cost, high-value magnetic photocatalytic composite. WRN was processed via a hydrothermal method to produce a solution containing carbon quantum dots (CQDs). Simultaneously, RM was dissolved in acid to form a Fe ion-rich solution, which was subsequently mixed with the CQDs solution and underwent hydrothermal treatment.
