Characterization of chars produced in the co-pyrolysis of different wastes: Decontamination study

摘要

The present work is devoted to the study of chars obtained in the co-pyrolysis of plastics, biomass and tyres wastes. The chars were extracted with several organic solvents in order to assess the more efficient in redicing the organic load of trhe chars and, therefore their toxicity. The ability of each selected extractant to remove toxic pollutants was evaluated by comparing the extracts yield and thoroughly characterizing the different crude extarcts obtained by combining chemical analysis and toxicity biossays. Also, the mineral composition of the treated and non treated chars was assessed. The results will allow to conclude which solvent should be used in the decontamination of the pyrolysis chars.
