Abstract: In the present study, char and activated carbon (AC) materials were prepared from water bottles, recuperated from the waste collection point in Mourouj, Ben Arous, Tunisia, by using a rotative horizontal tubular furnace, on a lab/pilot scale and through chemicalandphysicalactivation. Different samples were characterized by N2 adsorption isotherms, SEM-EDX, XRD, EA as well as by the determinationofthepHzpc.TheefficiencyoftheACstoremove(2-methyl-4-chlorophenoxyacetic acid (MCPA)and2,4-dichlorophenoxyacetic acid (2,4-D)) herbicides from aqueous solutions was also investigated. Theresults demonstratedthatamaximumadsorptioncapacityof192mg·g−1,forMCPA, and290mg·g−1 for2,4-Dhadbeenattained.Theadsorptionkineticswasfittedtopseudofirst,second order and Elovich model, while the adsorption isotherms were fitted applying the Langmuir and Freundlich isotherm models. The potential use as solid fuel materials was evaluated using elemental analysis and numerical high calorific value (HCV). The experimental results were compared to the conventional solid fuels classified in the Van Krevelen graph. The essays performed showed that the HCVwasintherangeof10.2–11.9MJ/kg.
