Materials from solid waste derived chars were activated at different temperatures and activation times to explore the influence of these parameters on the development of the surface area. It was possible to derive the influence of material and activation conditions on the final carbon surface area and the process was optimised to enhance the surface area development. Appropriate temperatures and soaking time maximised the porosity. However, the type of raw material restricted the activation conditions. Tyre crumb required higher temperatures, but was too reactive to allow lengthy soaking times as the development of macropores caused high mass loss. The development of activated
carbon from materials pyrolysed using the flaming pyrolyser was shown to be practicable. The best case of wood furniture
waste derived char developed a surface area (855 m2/g),which was 60% of that of commercially produced activated
carbons. The activation of tyre derived chars yielded an
