In this study, a tubular ceramic ultrafiltration membrane was synthesized using coal fly ash (CFA) along with fuller clay and a small quantity of inorganic precursors by extrusion method. The composition of membrane precursors was varied to prepare the ceramic membranes which were named as CM1, CM2 and CM3. Thermogravimetric analysis (TGA) confirmed high thermal stability nature of the membranes. The insignificant weight loss (<0.5%) of the membranes in a highly acidic and alkaline medium showed the high chemical resistance of the ceramic membranes. Mullite and Quartz was identified as significant phases of synthesized membranes via XRD analysis. The high negative charge of ceramic membranes was observed by Zeta potential analysis. Molecular weight cut‐off (MWCO) of CM1, CM2, and CM3 membranes were estimated as 59, 50.3 to 36.6 kDa, respectively. The proportion of fuller clay significantly influenced the membrane properties such as porosity, pore size, and hydraulic permeability. The pure water flux of the membranes was increased with increase of applied pressure from 69 to 345 kPa. The maximum water flux was obtained as 11.7 × 10−5 m3/m2 s at 345 kPa for CM1. The pore size and porosity of the membranes were decreased from 131 to 96 nm and 57.68% and 44.8% while increasing the fuller clay from 8% to 12% in the membrane (CM1 to CM3), respectively. The results obtained in this study demonstrate that the CM3 tubular ceramic membrane can be successfully used for various ultrafiltration applications.

“…The extractive industry generates large quantities of waste, such as ashes, sludges, and tailings, which can pose significant environmental risks if not managed properly. However, these waste materials often have the potential to be reused in different applications, such as construction materials, additives in ceramic products, fertilizers, and even in the production of new composite materials [7][8][9].…”

This article presents the development and characterization of environmentally friendly composites comprising polypropylene (PP) reinforced with Bahia Beige (BB) marble waste. The composites were prepared using different PP/BB weight ratios and analyzed for their chemical, physical, mechanical, microstructural, and thermal properties. X-ray fluorescence (XRF) analysis revealed the composition of BB, which exhibited a significant concentration of CaO, indicating the presence of calcite and other oxides. X-ray diffraction (XRD) analysis confirmed the presence of PP and identified calcite, dolomite, and quartz phases in the composites. Due to enhanced ceramic reinforcement, the composites displayed increased crystallinity with higher BB content. Fourier-transform infrared (FTIR) analysis demonstrated the interaction between PP and BB, with the bands corresponding to PP being replaced by bands related to BB as filler content increased. The density tests indicated a slight increase in composite density without deviating significantly from pure PP, which is advantageous for low-density applications. The hardness of the composites increased with filler content, while the impact resistance decreased notably. Scanning electron microscopy (SEM) images showed the good distribution of BB within the composites and the presence of ductile characteristics on the composite surface. The heat deflection temperature (HDT) results revealed that adding BB up to 40% by weight increased HDT, whereas a significant reduction occurred at a 50% BB content. These composites demonstrated favorable properties for engineering applications, offering a sustainable solution through utilizing natural waste resources and contributing to Brazilian sustainability efforts.
