Bioenergy generation potential from cotton stalks - a review - Projects
Updated : October 2020
Cotton stalk plant residue left in the field is a major carrier of pests and hence needs to be properly disposed of. However, studies say that it contains various forms of energy which can be used through different technology processes such as thermochemical and biochemical. This review article provides details on the same.
It discusses the characteristics of cotton stalks for energy potential compared with other energy crops. Key bioenergy conversion technologies suggested for cotton stalk to value include gasification, pyrolysis, hydrothermal carbonization, ethanol, biogas production and more. It also recommends new technologies for improved bioenergy recovery such as integrating anaerobic digestion and pyrolysis.
It concludes that pyrolysis, hydrothermal processes and anaerobic digestion could be potential avenues for sustainable cotton stalk to value conversion, however, more studies are needed to explore its potential for effective cotton waste utilization.
