The growing environmental impact of textile waste, fueled by the rapid rise in global fiber production, underscores urgent need for sustainable end-of-life solutions. This review explores cutting-edge pathways waste management, spotlighting innovations that reduce reliance on incineration and landfilling while driving material circularity. It highlights advancements collection, sorting, pretreatment technologies, as well both established emerging recycling methods. Smart collection systems utilizing tags sensors show great promise streamlining logistics automating pick-up routes transactions. For automated technologies like near-infrared hyperspectral imaging lead way accurate scalable separation. Automated disassembly techniques are effective at removing problematic elements, though other pretreatments, such color finish removal, still to be customized specific streams. Mechanical is ideal textiles with strong mechanical properties but has limitations, particularly blended fabrics, cannot repeated endlessly. Polymer recycling-through melting or dissolving polymers-produces higher-quality recycled materials comes high energy solvent demands. Chemical recycling, especially solvolysis pyrolysis, excels breaking down synthetic polymers polyester, potential yield virgin-quality monomers. Meanwhile, biological methods, their infancy, natural fibers cotton wool. When methods not viable, gasification can used convert into synthesis gas. concludes future hinges integrating sorting advancing solvent-based chemical technologies. These innovations, supported eco-design principles, progressive policies, industry collaboration, essential building a resilient, circular economy.

Production of transportation fuels via hydrotreating of scrap tires pyrolysis oil

Chemical Engineering Journal, Journal Year: 2023, Volume and Issue: 460, P. 141764 - 141764

Published: Feb. 8, 2023

The hydrotreating of scrap tires pyrolysis oil over commercial Ni-Mo/Al2O3 catalyst was researched for the best processing scheme allowing production high-quality alternative transportation fuels components gasoline, jet, diesel, and marine fuel. Despite initial high content olefins, aromatics, sulfur, nitrogen in oil, fuel obtained by redistillation after at 360 °C 10 MPa met majority standard specifications. Although octane number naphtha fraction lower, this can be used as a component gasoline pool directly or catalytic reforming. Kerosene utilized jet additional mild hydrotreatment blending with hydroprocessed esters fatty acids (HEFA) to decrease aromatics content. Diesel blended hydrotreated vegetable oils (HVO) fulfill density cetane index specification. bottom residue low-sulfur transportation.

Published: March 6, 2024

Pyrolysis is a promising way to reuse of waste tires. However, the carbon black generated in process often contaminated with various pyrolysis products. This study aims recycle low-quality recycled (rCB) from tire pyrolysis, addressing challenges posed by organic residues (up 5 wt% bituminous substances, 112.2 mg/kg PAH). causes agglomeration particles and decreases active specific surface area. Cavitational vortex milling (both wet dry) emerges as method valorize rCB, allowing for significant reduction concentration contaminants. novel allows generation hydrophilic hydrophobic pigments. In parallel experiments, rCB incorporated into solid biofuel enhance its calorific value. The addition 10 rCB) peat significantly elevates value 14.5 MJ/kg 21.0 MJ/kg. this improvement accompanied notable increases CO2 SO2 emissions. dual effect underscores necessity considering environmental consequences when utilizing supplement biofuels. findings provide valuable insights potential cavitational valorization highlight trade-offs associated enhancing properties through rCB.

Energy & Fuels, Journal Year: 2023, Volume and Issue: 37(13), P. 8836 - 8866

Published: June 20, 2023

Pyrolysis is perceived as the missing link between management of end-of-life tires (ELTs) and tire industry because it strikes directly in transition from a linear to circular economy model toward defossilization diverse economic sectors. Tire pyrolysis oil (TPO) one most valuable interesting fractions derived ELTs. It contains chemicals including, among others, benzene, toluene, ethylbenzene, xylene, well limonene, which are some building blocks petrochemical industry. Within framework, traditional practices such direct use TPO combustion systems seem exhibit low circularity degree. Instead, production secondary raw materials that can be reused for multiple purposes associated with getting special attention. Based on above, this work aims at reviewing different pathways currently explored scientific community produce various value-added products TPO. Due similarity its properties those petroleum streams, coprocessing using existing units conventional refineries exhibits massive potential. In manner, fine-tuned according hydrocarbons market requirements. As such, discussed advantages, recent progress, challenges implementation refinery distillation, fluid catalytic cracking (FCC), hydroprocessing, steam post-treatment. These processes seen path integrate current hydrocarbon/petrochemical market.
