The content of lignin is also different for different species and ranges between 25-30% for soft plants and can be as high as 50% for ebony like hard species of plant. The major elemental components like carbon are up to 65%, for hydrogen, it is between 5-6%, and the rest are mostly oxygen [56]. The methoxylation of the compounds plays a very crucial role, and because of it, the composition varies [57]. At the temperature of around 128 °C, dry lignin begins to soften, but this also depends on the molecular weight and with the increase in molecular weight, the softening temperature is bound to increase [58]. The availability of lignin is quite high [59, 60]. It has got higher calorific value as compared to cellulose [61] and can be subsequently used for the production of bioplastics, additives etc. [62]. Several high valued components are produced from it [63–66].
