Evaluation on isothermal pyrolysis characteristics of typical technical solid wastes

•Pyrolysis behavior of typical technical solid wastes was examined.•Co-pyrolysis index and products of PE, paper towel and textiles were evaluated.•There was certain interaction between the components during the co- pyrolysis.•More alkanes and olefin in the liquid product of the blend were identified.•The solid residues from the mixture pyrolysis were about 11.6 percent (wt.).
