Possibilities to Use Textile Cord Waste From Used Tires for Concrete

Abstract

Abstract. Trinitrotoluene (TNT), a commonly used explosive for military and industrial applications, can cause serious environmental pollution. 28-day laboratory pot experiment was carried out applying bioaugmentation using laboratory selected bacterial strains as inoculum, biostimulation with molasses and cabbage leaf extract, and phytoremediation using rye and blue fenugreek to study the effect of these treatments on TNT removal and changes in soil microbial community responsible for contaminant degradation. Chemical analyses revealed significant decreases in TNT concentrations, including reduction of some of the TNT to its amino derivates during the 28-day tests. The combination of bioaugmentation-biostimulation approach coupled with rye cultivation had the most profound effect on TNT degradation. Although plants enhanced the total microbial community abundance, blue fenugreek cultivation did not significantly affect the TNT degradation rate. The results from molecular analyses suggested the survival and elevation of the introduced bacterial strains throughout the experiment. Keywords: TNT, bioaugmentation, biostimulation, phytoremediation, microbial community.

Sound Absorption Properties Evaluation and Analysis of Recycled Tyre Textile Fibre Waste

“…The studies were conducted on use of RTTF in concrete [27], asphalt production [28], and polypropylene products [29] on mechanical properties improvement, however acoustic properties of RTTF are not tested yet. The reuse of RTTF is proposed within this paper.…”

Fabrication and performance evaluation of waste cotton and polyester fiber‐reinforced green composites for building and construction applications

“…There are plenty of applications where waste textiles can be utilized. Textile waste materials have applications in the production of ethanol, [4] glucose, [5] nanocellulose and cellulose nanocrystals (CNC), [6,7] microcrystalline cellulose, [8] biogas, [9] thermal and sound insulation materials, [10] concrete and bricks, [11] activated carbon, [12] dye absorbing nonwovens, [13] fibers, yarns and fabrics [14,15] paper making, [16,17] and polymer composites, [18] and so forth. The application of textile waste in the polymeric composite as reinforcement can make a difference compared to virgin materials.…”

Neapdorotų Padangų Tekstilės Pluošto Atliekų Garso Sugerties Tyrimai

“…Teigiama, kad pridedant nedidelius kiekius PTP atliekų į molinguosius ir smėlinguosius gruntus, įvairios mechaninės jėgos padidėja (Abbaspour et al, 2019;Narani et al, 2020;Zare et al, 2020); -Betono gamyboje. Atliekant tyrimus buvo nustatyta, kad PTP atliekos nepagerina mechaninių betono savybių, bet sumažina gaminio šiluminį laidumą (Malaiškienė et al, 2015;Baričević et al, 2018). -Asfalto gamyboje.…”
