The wooden railroad ties have a lifespan of approximately 50 years. When replaced, they need to be stored and destroyed very carefully because they are impregnated by creosote and polluted by the rail use. In combustion applications of this biomass, the pollutants, mainly polycyclic aromatic hydrocarbons and heavy metals are freed restricting the energetic valorization of crossties to incinerators equipped with suitable flue gas treatment. As an alternative, this paper presents the results of an...
