Description
Summary:Rapidly changing fashion trends have generated tremendous amounts of textile waste globally. Textile waste is composed of a variety of substances (natural, synthetic, organic, and inorganic fibers). The inhomogeneity and complex nature of textile waste makes recycling economically challenging. Pyrolysis is a thermochemical process that transforms waste feedstocks of an inhomogeneous and complex nature into value added products (i.e., waste upcycling). This article provides a systematic review of the currently available and investigated pyrolysis processes to upcycle textile waste (e.g., material and energy recovery). The challenges in the pyrolysis process of textile waste are discussed, and relevant future research needs are recommended. Despite these challenges, pyrolysis will be an effective end-of-life option for textile waste if continuous research and development activities are conducted. [Display omitted] •Types of pyrolysis processes and reactors for textile waste upcycling are compared.•Performance of pyrolytic conversion of textile waste to carbon materials is evaluated.•Performance of energy recovery from textile waste via pyrolysis is discussed.•Challenges and prospects for textile waste upcycling via pyrolysis are highlighted.
