“…The mechanical properties of GF can be significantly reduced after pyrolysis, but its thermal conductivity is comparable to commercial thermal insulation materials. 42 Moreover, the GF recovered from the pyrolysis of end-of-life WTBs is suitable for heat insulation and sound insulation materials. Therefore, the pyrolysis process can completely dispose of end-of-life WTBs, and has the advantages of capacity reduction and resource recovery.…”

“…Additionally, some environmentally preferred pyro-product processing options are not well established yet but could emerge as competitive options in the future. It is therefore considered crucial to develop cost-effective chemical segregation processes to make pyrolysis profitable [32]. To address these challenges, SSP-aligned scenarios were developed based on each potential option, post-processing, and application in 2030, 2040, and 2050 for each scenario.…”

“…However, the pyrolysis processing technology is yet to be tested on an industrial scale for WTB waste [28]. In the majority of the reviewed studies, fiber recycling is considered, but upcycling of higher-value products, e.g., fuel and chemicals, is scarcely investigated [32]. Pyrolysis is also considered a costly and energy-intensive process because of the high process temperatures applied [23].…”

This study presents a sustainable end-of-life (EoL) value chain scenario assessment framework for decommissioned wind turbine blades (WTBs) to address the challenge of increased volumes of WTBs reaching their EoL. Findings from the previous studies highlight that WTBs EoL scenarios and their upscaling are yet to be addressed environmentally and economically. The scenarios investigated herein are mechanical shredding, pyrolysis, and cement co-processing that can be industrially upscaled. Together with the industrial partners, end-of-life scenario value chains are identified, to assess their sustainability through material flow analysis (MFA), life cycle assessment (LCA), and techno-economic assessment (TEA). A prospective consequential LCA model is proposed for scenarios with different technology readiness levels (TRL) expected to be commercialized at different timeframes. IPCC’s Shared Socio-economic Pathways (SSPs) will be used to describe foreground and background systems in 2030, 2040, and 2050. More specifically, SSP1 (i.e., green road), SSP2 (i.e., middle road), and SSP5 (i.e., fossil-fueled development) will be employed and quantified based on integrated assessment models (IAM). Furthermore, environmental impacts, economic criteria, Social sustainability, and circularity cannot directly be compared to evaluate the scenarios. Thus, this research proposes multi-criteria decision-making (MCDM) method to evaluate the three end-of-life scenario value chains considering a prospective scheme and addressing the key challenges related to the assessment of emerging technologies. Furthermore, a full conceptual framework of the methodology is presented.

“…The potential impact on the environment is enormous: for example, waste from old fishing nets, wind turbine blades or conventional plastic waste can be converted to energy and high-value materials. [41][42][43] Herein, biomass or biowaste has also been considered as a feedstock. 44,45 However, even though some studies on the production of syngas or hydrogen from biomass or biogas have been conducted in the past, 6,[46][47][48][49][50][51] the usage of biogas under reaction conditions of thermocatalytic pyrolysis of methane remains mostly unexplored.…”
