Abstract Global warming and depletion of non-renewable resources like fossil fuels, escalating the need for the development of environmentally acceptable and sustainable product by utilizing the naturally available renewable biomass. Prosopis juliflora (PJ), a highly ecological disruptive species was considered to a be a renewable biomass that was utilized in the production of biopolyol under four different liquefaction methods such as solvolytic, hydrothermal, phenol and microwave assisted liquefaction method. The wood and bark of Prosopis juliflora (biomass) were subjected to grinding, pretreatment and finally analysed using FTIR, TGA, DSC. After the liquefaction of both the biomass, the liquefied biopolyol was initially underwent solubility checking, identification of hydroxyl and acid number, measurement of initial pH value. Then to identify the functional group, structure, thermal properties of biopolyol, it was put through the characterisation like FTIR, NMR, TGA and DSC. This study highlights the importance of waste to resources approach by transforming an ecologically prevalent species into renewable chemical feedstocks, which supports green initiatives alongside industrial innovation.
Keywords Prosopis juliflora (PJ), lignocellulosic biomass, liquefaction, biopolyol, solvolytic, hydrothermal, phenol, microwave assisted, FTIR, TGA and DSC
