Thermochemical conversion of cabbage waste to bioenergy and bio-chemicals production

This study sheds light upon how the decomposition of cabbage waste (CW) is brought to make it capable of providing bioenergy along with bio-chemicals. The CW is evaporated through three steps, and at the same time, non-condensable products (NH3, CO2, CH4, CO, SO2 and NO) and condensable products like (H2O, CH3CH2OH, CH3COOH, C(sic)C, C6H5OH and HCOOH) are yielded. The products that have gone through the pyrolysis process comprise 45% condensable products. Thermogravimetry-Fourier transform infrared (TG-FTIR) analysis shows that lower temperature can be more effective for condensable products formation from CW as compared to higher temperature. Pyrolysis gas chromatography (Py/GC-MS) confirms presence of the high energy and value-added chemical compounds such as toluene, benzene and phenols among pyrolytic products. According to initial reports, liquid pyrolytic products produce more than 70% energy. All these results demonstrate that CW could be promising source of bioenergy and valuable bio-chemicals production via pyrolysis.
