Production of High-Hydrogen-Content Gas Via Thermochemical Conversion of Textile Waste

Short Introductive summary

The fast-fashion model has led to a sharp increase in global textile production and waste generation, creating a major environmental challenge. Conventional mechanical and chemical recycling methods are insufficient to handle the complex composition of textile residues, which often include blended fibers, dyes, and chemical additives. This study explores an alternative valorization strategy based on the thermochemical conversion of textile waste to produce a hydrogen-enriched synthesis gas (syngas) as a renewable energy carrier. The generated syngas is utilized to feed a Solid Oxide Fuel Cell (SOFC), enabling the direct conversion of hydrogen into electrical energy. The process optimization focuses on maximizing hydrogen yield, improving energy efficiency, and ensuring gas purity through sulfur removal. This approach demonstrates the potential to transform non-recyclable textile waste into valuable clean energy, aligning with circular economy principles and supporting the decarbonization of the textile sector.
