“…The output of mechanical recycling can be used, among other options, as fillers, reinforcements or as raw material to produce new plastic products or for the production of cement [34], which means that the output can be divided into two categories: utilization of materials and co-processing. Here, a distinction is made between whether the residual product, after being processed, is used for the creation of new products (utilization of materials) or as a substitute for new raw materials for the production of new material (co-processing) [35]. During the co-processing phase, it will be possible both to benefit from energy recovery and material recovery.…”

Wind energy has seen an increase of almost 500 GW of installed wind power over the past decade. Renewable energy technologies have, over the years, been striving to develop in relation to capacity and size and, simultaneously, though with less focus on, the consequences and challenges that arise when the products achieve end-of-life (EoL). The lack of knowledge and possibilities for the recycling of fiber composites and, thus, the handling of EoL wind turbine blades (WTBs) has created great environmental frustrations. At present, the frustrations surrounding the handling are based on the fact that the most commonly used disposal method is via landfills. No recycling or energy/material recovery is achieved here, making it the least advantageous solution seen from the European Waste Commission’s perspective. The purpose of this research was thus to investigate the current recycling methods and to categorize them based on the waste materials. The opportunities were compared based on processing capacity, price, environment and technology readiness level (TRL), which concluded that recycling through co-processing in the cement industry is the only economical option at present that, at the same time, has the capabilities to handle large amounts of waste materials.

“…Vladimirov and Bica explain the multiple benefits of the mechanical recycling of glass fiber composites [ 77 ], including the simple equipment needed, avoiding the use of solvents or high energy consumption, although the main drawback continues to be the lack of uniformity on the final product obtained, due to the different types of glass fiber composites available on the market. To overcome this, glass-fiber reinforced polymers can be recycled though pyrolysis performed in a fluidized bed, recovering around 50% of the initial glass fibers, to be reintroduced into a polymer matrix to obtain a new composite.…”

This paper assesses the aspects related to sustainability of polymer composites, focusing on the two main components of a composite, the matrix and the reinforcement/filler. Most studies analyzed deals with the assessment of the composite performance, but not much attention has been paid to the life cycle assessment (LCA), biodegradation or recyclability of these materials, even in those papers containing the terms “sustainable” (or its derivate words), “green” or “eco”. Many papers claim about the sustainable or renewable character of natural fiber composites, although, again, analysis about recyclability, biodegradation or carbon footprint determination of these materials have not been studied in detail. More studies focusing on the assessment of these composites are needed in order to clarify their potential environmental benefits when compared to other types of composites, which include compounds not obtained from biological resources. LCA methodology has only been applied to some case studies, finding enhanced environmental behavior for natural fiber composites when compared to synthetic ones, also showing the potential benefits of using recycled carbon or glass fibers. Biodegradable composites are considered of lesser interest to recyclable ones, as they allow for a higher profitability of the resources. Finally, it is interesting to highlight the enormous potential of waste as raw material for composite production, both for the matrix and the filler/reinforcement; these have two main benefits: no resources are used for their growth (in the case of biological materials), and fewer residues need to be disposed.

“…To recycle the FrP wastes, some recycling methods as chemical, mechanical, thermal, and comprehensive recovery [1][2][3][4] as well as filler in concrete and mortars [5][6][7][8] are developed. correia et al [9] claim that landfilling is the least preferable option and countries like Germany have already forbidden composite landfilling.…”

Accordingly with the principles of the circular economy, mixed plastic wastes can be recycled also by thermoforming, getting new non-oriented fibers composite materials. this study highlights the mechanical behavior of new composite material plates containing recycled glass fibers as reinforcing element and ABs-PMMA mixture as matrix, as well as an efficient way to convert a manufacturing process wastes in a product. the mechanical behavior of new composite material plates was evidenced by tensile, flexural and compression tests. in addition a surface morphology analysis was performed.
