## 2 Materials and Methods
### Methods  
The fishing gear delivered by SMEL has a service life exceeding 10 years. By spending a significant amount of time in saltwater, the surface of WFT and WFR is likely to accumulate a substantial amount of salt. This salt accumulation may negatively impact the mechanical performance of CM [33]. Manual cleaning is a laborious and sluggish process, while machine cleaning requires a significant amount of water and power. As an example, a typical 8 kg washing machine utilizes around 60 to 70 L of water and 0.1 to 0.3 kWh of power over a period of 3 h. In order to circumvent the laborious and resource-intensive approach, we have used a sustainable technique that harnesses natural elements such as rain and wind to cleanse these fishing tools. The WFT and WFR were exposed to rain and wind for a certain duration, and subsequent salinity tests were conducted to determine the salt content in them.  
The second step is to cut these fishing gears into fibers, keeping in mind the industrial point of view. This article has tried to define the protocol for efficiently cutting WFT and WFR into fibers at a large scale using a cutting machine (see Figure 3). This machine, featuring RES technology and a powerful 3 kW drive with high torque, is a high-performance cutting apparatus ideal for cutting soft, medium-hard, tough, elastic, fibrous, and heterogeneous materials. It offers variable speed control from 100 to 3000 RPM and a range of bottom sieves with aperture sizes from 0.25 to 20 mm, ensuring precise fiber size.  
The workability of controlled mortar (MC) and mortar incorporating WFT (MWFT) and WFR (MWFR) fibers was measured using a flow table following French standard NF EN 1015-3, (1999). Consistency is a parameter that quantifies the viscosity and moisture content of newly mixed mortar. It indicates the ability of the fresh mortar to deform under specific stress conditions. The flow value is determined by measuring the mean diameter of a test sample of fresh mortar deposited on a defined flow table disc using a defined mold and subjected to several vertical impacts by elevating the flow table and allowing it to fall freely through a given height.

The compressive strength (R\({}_{\rm C}\)) tests were conducted on 4 cm \(\times\) 4 cm cubical samples using a compression test apparatus (NF EN 196-1, 2016) that was equipped with a compression force sensor capable of applying a normal load up to 250 kN with an accuracy of \(\pm\)0.1% and at the rate of 2400 N/s. The determination of the uniaxial R\({}_{\rm C}\) of a specimen can be achieved by the maximal force value (F) per area of the specimen (A\({}_{\rm c}\)) according to Equation (1).  
\[\rm R_{c}=\frac{F}{A_{c}} \tag{1}\]  
The flexural strength (R\({}_{\rm f}\)) of mortar was determined by a three-point bending test (NF EN 196-1, 2016) with a machine capable of applying a load of up to 10 kN with a rate of loading 50 N/s. The R\({}_{\rm f}\), in N/mm\({}^{2}\), was calculated using the following formula:  
\[\rm R_{f}=\frac{3F\times 1}{2b\times d^{2}} \tag{2}\]  
where F is the maximum load applied to the specimen, in newtons (N); I is the distance between the support rollers, in millimeters (mm); b is the width of the specimen, in millimeters (mm); d is the depth of the specimen, in millimeters (mm).
