Resourceful utilization of the enormous quantum of agrowastes generated via agricultural practices can be supportive in waste management, environmental upgradation, and subsequent material and energy recovery. In this regard, the present study aimed at highlighting waste banana (Musa balbisiana Colla) pseudostem (an agrowaste) as a potential bio-based feedstock with miscellaneous applications. The pseudostem was characterized by carbon, nitrogen, and hydrogen (CHN) analysis, thermogravimetric-differential thermal analysis (TGDTA), and Fourier transform infrared (FTIR) spectroscopy. Cellulose, hemicellulose, and lignin were estimated as a part of biochemical characterization. Total phenolic content, total flavonoid content, 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay, and ferric reducing antioxidant power (FRAP) were carried out as a part of antioxidant characterization. The waste banana pseudostem biomass (WBPB) was also tried successfully as a natural filler in polyvinyl chloride (PVC) polymer composite. Thermal properties and water uptake test of the WBPB polymer composite were accessed as a part of composite characterization. The pseudostem had calorific value (15.22 MJ/kg), high holocellulose (58.67%), high free radical scavenging potential (69.9%), and a low ash content (6.8%). Additionally, the WBPB polymer composite showed improved water resistance and thermostability. The study suggests feasibility of WBPB as a prospective bioenergy feedstock, primary antioxidant source, and reinforcing agent in polymer composites.
