The development of mulch films from vegetable waste represents a sustainable alternative to the traditionally used polyethylene films that follow the principles of the circular economy. In this work we have films based on two different industrial vegetable waste, the orange peel (OP) and the spinach stalks (SS), by hydrolysis at different times (6, 16 and 24 h) and temperatures (30, 50, and 70 ° C ). The hydrolysis carried out at 30 ° C and 24 h led to the films with the best mechanical properties, while high temperatures (70 ° C) in combination with extended treatment times (16 and 24 h) led to materials with lower mechanical resistance and darker coloration. The characterization of the films by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), thermogravimetric analysis (TGA) and uniaxial tensile tests clarified their chemical structure and physico-chemical properties. In addition, the interaction of the materials with water was evaluated and significantly improved by adding a carnauba wax coating. Optical properties, micro and macronutrient content and biodegradability in the soil of selected bioplastics were also determined. The results showed that the proposed materials have rapid soil biodegradation, good weed prevention potential, and plant growth improvement through soil fertilization.
