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

Abstract

Summary 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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.

The Valorization of Wastes and Byproducts from Cruciferous Vegetables: A Review on the Potential Utilization of Cabbage, Cauliflower, and Broccoli Byproducts

“…As the biomass is heated to a high temperature, it undergoes thermal decomposition, and the biomass's complex organic molecules break down into simple compounds [42]. The pyrolysis of cabbage waste demonstrated potential in the production of bioenergy and bio-chemicals, resulting in the formation of 45% condensable compounds [59]. Pyrolytic products contain high-energy chemical compounds like toluene.…”

Spinel CoFe2O4 Nanoflakes: A Path to Enhance Energy Generation and Environmental Remediation Potential of Waste-Derived rGO

“…Waste from agricultural industry is increasingly attracting attention for the role it may play in environmental remediation and in reducing greenhouse gas emissions as the global communities move towards a cleaner world [ 1 , 2 , 3 ]. For material synthesis, biomass waste is a valuable source of carbon and trace minerals [ 4 , 5 , 6 ], where the micro- and nanostructure of the material may give rise to unusual material architectures without the need for complex templates or multi-step processes [ 7 , 8 , 9 , 10 , 11 , 12 ]. With an attractive combination of properties such as good conductivity, high surface area and chemical reactivity, these multipurpose materials can underpin sustainable circular economy by enabling new efficient nanomaterial-based devices [ 13 , 14 ] and functional coatings [ 15 , 16 , 17 ].…”

Sustainable coke-resistant Ca-Al nano-sized catalyst for cogenerating of H2 and high value liquid fuels via pyrolysis catalytic steam reforming reaction of the polystyrene-phenol mixture

“…Furthermore, due to the equilibrium between the attenuation of the reforming and WGS processes and the augmentation of the cracking reactions, catalyst deactivation has no appreciable impact on the CO yield in the reforming of the volatiles produced at 500 °C. stretching vibration of ester groups 79 and C−F stretching of fluoro compound, while transmittance peaks at 1219 cm −1 could be assigned to the -COH functional group of phenolic compounds 80 . The bands at 1358 cm −1 and 1427 cm −1 were assigned to the aromatic C=C absorption 81 and O−H bending vibration 82 , respectively.…”
