| Summary: | The increasing generation of waste wood (WW) and the demand for activated carbon (AC) in wastewater treatment highlight the need for sustainable alternatives. WW was converted into AC via one-step thermochemical activation using carbon dioxide, steam, or both in a fluidised-bed reactor. A Design of Experiments approach was applied to optimise temperature and residence time. The resulting ACs achieved surface areas up to 708 m2 g−1 and adsorption capacities of 254 mg g−1 for organic micropollutants. The process yielded favourable porosity and surface chemistry. It supports circular economy principles and offers a scalable route aligned with current environmental regulations. |
