Chemical and ecotoxicological characterization of solid residues produced during the co-pyrolysis of plastics and pine biomass

Toxicity of char residues produced in the co-pyrolysis of different wastes

“…This treatment was performed to evaluate if DCM extraction is a technical viable option to decrease the hazard potential of the chars. It was previously demonstrated by Bernardo et al (2009) that DCM is able to extract a large range of volatiles from solid residues produced during the co-pyrolysis of plastics and biomass, decreasing their ecotoxicity and consequently their hazard potential.…”

“…The selection of heavy metals to be determined in the wastes was made based on a previous study (Bernardo et al, 2009), in which the content of metals in plastics and pine biomass used in pyrolysis assays were performed in a broad spectrum. Zinc, lead and copper were detected in these wastes in significant concentrations.…”

“…Table 2 shows the concentrations of two groups of selected organic compounds in both eluates. The 15 aromatic hydrocarbons and the 11 alkyl phenols were selected taking into account results from a previous work (Bernardo et al, 2009). In this previous work, the authors have studied the organic qualitative profile of eluates from chars obtained in the co-pyrolysis of plastics and pine biomass.…”

“…In particular, combined studies on the chemical and ecotoxicological properties of chars produced in co-pyrolysis were not identified. The authors have recently presented a work devoted to this subject (Bernardo et al, 2009), in which an ecotoxicological classification of this type of residues was made.…”

Bio-oils from biomass slow pyrolysis: A chemical and toxicological screening

“…A few studies provide information about the hazards posed by bio-oils obtained from biomass pyrolysis [8][9][10][11][12][13]. Data on the hazards of biomass co-pyrolysis products are reported by Bernardo and coworkers [14][15][16]. Material Safety Data Sheets have been also proposed for some bio-oils [8,17,18].…”
