<p>Natural fabrics, such as jute fabrics, can be used as geotextiles, and are called jute geotextiles (JGTXs). Natural treatments using turmeric spent powder and soap nuts have been recognized for their surfactant properties. These natural alternatives are considered more effective and sustainable compared to chemical treatments, which often have higher toxicity. The primary objective of the present study was to develop a more durable and sustainable treatment for JGTXs using turmeric spent powder and soap nut. JGTXs were treated with chemical (chlorpyrifos) and natural agent (the combination of turmeric spent powder which is a biomass and soap nuts) to enhance their resistance against accelerated degradation. A wetting–drying test was designed to accelerate degradation. Untreated and treated JGTXs were subjected to alternate wetting–drying cycles of 10, 30, and 60 under different aqueous mediums in neutral (pH 7), acidic (pH 4), and alkaline (pH 11) media. The degradation was measured in terms of weight, thickness, tensile strength, and hole diameter. Naturally treated JGTXs subjected to alternate wetting–drying cycles under alkaline environmental conditions retained about 50% of their initial tensile strength after 60 cycles. In contrast, untreated JGTXs lost 86.42% of their initial tensile strength after the same number of cycles. Increasing the utilization of turmeric spent powder aligns with biorefinery and circular bioeconomy principles and contributes to the achievement of sustainable development goals.</p>
