We investigate engineering applications of recycled nylon fibers obtained from waste fishing nets, focusing our attention on the use of recycled nylon fibers as tensile reinforcement of cementitious mortars. We begin by characterizing the tensile behavior of both unconditioned and alkali-cured recycled nylon fibers obtained through manual cutting of waste fishing net filaments, with the aim of assessing the resistance of such materials to chemical attacks. Special attention is also given to evaluating the workability of fresh mortar and the possible impacts of contaminants released by waste fishing nets into the environment. Next, we deal with compression and bending tests on cementitious mortars reinforced with recycled nylon fibers, and establish comparisons with the experimental behavior of the unreinforced material and with results given in existing literature. In our analysis of different weight fractions and aspect ratios of the reinforcing fibers, we observe marked increases in the tensile strength (up to +35%) and toughness (up to 13 times greater) of the nylon reinforced mortar, as compared with the unreinforced material. The presented results emphasize the high environmental and mechanical potential of recycled nylon fibers for the reinforcement of sustainable cement mortars.

• Recycling of plastic solid waste: A state of art review and future applications (2017, background): “Similarly, recycled PET and nylon fibres showed to me most effective in the reinforcement of low-strength cement mortars than high-strength cement mortars [44,123].”
• On the reinforcement of cement mortars through 3D printed polymeric and metallic fibers (2016, background): “It is worth noting, however, that most of specimens analyzed in the present work exhibit flexural collapse under deflections lower than 5:5 d, which make it impossible to compute the toughness index I10 and the residual strength factor R5,10 [14,15] for such materials.”
