Ingesting <i>Lantana</i> leaves can lead to severe symptoms, including nausea and liver damage. <i>Lantana</i> pollen can exacerbate respiratory conditions like asthma. Effective management strategies are essential to mitigate these health risks. Pharmaceutical pollution is an emerging crisis in wastewater and even groundwater. This is exacerbated by the huge global consumption of pharmaceuticals. Converting <i>Lantana</i> into biochar offers a solution that was tested for removing acetaminophen (ACM) as a model pharmaceutical compound, addressing both environmental and health concerns. <i>Lantana</i> is globally ranked among the top 10 worst invasive species. In India, ∼132,000 km<sup>2</sup> of pasture lands and ∼303,607 km<sup>2</sup> of forest lands are colonized by <i>Lantana</i>, making it a reliable biochar feedstock. <i>Lantana</i> biochar (LB700) was produced through slow pyrolysis of dried <i>Lantana</i> at 700 °C (ramp rate = 7 °C/min) and subsequently employed for aqueous ACM sorption. LB700 was characterized by its Brunauer–Emmett–Teller (BET) surface area, morphology, functional groups, crystallinity, and elemental composition. Batch ACM sorption was performed to find the influence of pH, initial ACM concentration, LB700 dose, and temperature. Equilibrium sorption data were interpreted using Freundlich, Langmuir, Temkin, Toth, Redlich–Peterson, and Sips isotherm models, while kinetic data were analyzed using pseudo-first- and second-order rate equations. Maximum ACM adsorption (4.5 mg/g) occurred at pH 2 with 1.0 g/L of LB700 dose. ACM sorption drastically reduced after pH 8 due to electrostatic repulsion between deprotonated ACM and negatively charged LB700. Pseudo-second-order equation best-fitted with kinetic data (<i>R</i><sup>2</sup> = 0.91–0.97). A maximum Langmuir adsorption capacity of 13.2 mg/g was obtained at 40 °C. The spontaneity and endothermicity of the reaction were inferred from negative Δ<i>G</i>° (−19.73 to −24 kJ/mol) and positive Δ<i>H</i>° (20.82 kJ/mol) values, respectively. The π–π stacking, H-bonding, van der Waals interactions, and pore diffusions are the dominant interactions. This study ingeniously addresses two pressing issues, <i>Lantana</i> invasion and pharmaceutical wastewater management, by providing an alternative solution through large-scale conversion of <i>Lantana</i> into biochar for treating pharmaceutical wastewater. Moreover, by converting <i>Lantana</i> into biochar, it effectively mitigates the health effects associated with this invasive plant, ensuring the preservation of environmental health and safety.

The integration of AI tools in safety systems holds promise to revolutionize risk assessment and accident prevention across various industries. These advanced technologies can process vast amounts of data to identify potential hazards, predict incidents, and recommend preventive measures with an unprecedented speed.
