Textile manufacturing is one of the oldest technologies used by man. Brazil is one of the largest world producers in the textile sector, and is still an important producer of cotton fiber, producing an average of 9 billion pieces per year. An alternative to avoid inappropriate destination is recycling. Thus, this research investigated the technological feasibility for the conversion of textile waste, composed of cotton, viscose and linen fibers through the pyrolytic process. The pyrolysis was carried out in a cylindrical reactor without gas flow, at temperatures of 500 and 700°C and times of 30 and 60 minutes. The results revealed that, among the 137 types of textile composition distributed in 801 types of fabrics with different weight, color or weave, fabrics A (100% Cotton) and VLA (65% Viscose, 21% Linen, 14% Cotton) were those chosen for this research. The results of the generated biomass and by-products, revealed characteristics for use in the chemical and energy industry, since the higher calorific value was 2.214 Kcal/Kg, due to the low moisture and ash content, high volatile material content, low density and high content of C and H found in textile residues A (47.64%) and VLA (44.91%). The solid textile material was compared to bituminous coal in C, N and H levels and TOC content. Therefore, it is possible to conclude that the textile residues A and VLA presented favorable physicochemical characteristics not only for energy production, but also for use in other industrial sectors.
