Tunisia faces severe groundwater challenges, including overexploitation, salinization, and pollution from agricultural and industrial sources, exacerbated by climate change. Non-Point Source pollution has emerged as a critical environmental challenge, which led to a supply of residual pollutants and organic compounds (such as Bisphenol A) into soils and surface waters. Biochar has been shown to be a promising solution due to its low cost, and high adsorption efficiency. The aim of this study is to develop cost-effective and eco-friendly biomaterials from agricultural waste for the selective removal of BPA.
