Abstract

A response to the environment with synthetic leather. This study reconnoiters the potential of plant-based leather derivative from Solanum Lycopersicum (tomato), Agro-Barren, with a natural dyeing process using Ceratonia Siliqua (carob). A Box-Behnken design was used to optimize the effect of the processing (temperature, pressure, and time) on the mechanical, thermal, and morphological properties of the leather. The leather tensile strength, elongation break, and stiffness were considered complete standard mechanical testing (ASTM D38) and (ASTM D-790). Scanning Electron Microscopy (SEM) was used to assess the surface morphology, revealing an even and compressed structure with varied fiber alignment that contributes to its mechanical integrity. Additionally, thermal stability was evaluated via Thermogravimetric Analysis (TGA), indicating favorable heat resistance and properties compared to other plant-based alternatives. A comparative analysis with conventional synthetic and plant-based vegan leather, including those made from pineapple leaves and cork, established that the tomato-based leather exhibits similar or superior tensile properties and bio-degradability, with a lower environmental footprint. The novelty of this study proposes that tomato agro-waste, when processed under optimized environments, can serve as a visible and suitable sustainable alternative to traditional leather, with application in industries such as fashion products and outer cover material.
