Insight into synergistic effects of biomass-polypropylene co-pyrolysis using representative biomass constituents.

The co-pyrolysis behavior of plastic (PP) with six biomass components (cellulose, hemicellulose, lignin, carbohydrate, lipid, protein) was studied by thermogravimetry. The overlap ratio (OR) and the difference in experimental and theoretical weight loss (ΔW) are defined. The results demonstrated that the interaction of lignin and PP was notable with the OR of 0.
