The increasing concerns of environmental pollution and shortage of petroleum resources have fueled substantial research towards valorization of bio-based polymers. Lignin is the second most abundant renewable biopolymer on Earth and the largest natural source of aromatic monomers. Its industrial use has attracted considerable attention because of its advantages of high carbon content, low cost and bio-renewability.
Wood pulping and other biorefinery industries extract more than 50 million tonnes of lignin annually, but only ~2% is recovered for utilization in applications. However, it's use as a ‘green’ feedstock for fuels, chemicals, and materials is growing through the commercialization of extraction technologies coupled with transitioning towards biorefinery processes.
Lignin has mainly been produced as an industrial residue of pulp and paper factories (e.g. a by-product of the Kraft process), and the majority of the several millions tons of lignin produced annually are utilized as a low-cost fuel for power and heat generation. Due to continued greening (i.e. renewable feedstock) of the global economy, new applications are being commercialized. For example, lignin-based renewable functional fillers are used in different rubber applications as a sustainable alternative to carbon black and silica.
