Global status of lignocellulosic biorefinery: Challenges and perspectives

The bioprocessing of lignocellulosic biomass to produce bio-based products under biorefinery setup is gaining global attention. The economic viability of this biorefinery would be inclined by the efficient bioconversion of all three major constituents of lignocellulosic biomass i.e. cellulose, hemicellulose, and lignin for value-added biochemicals and biofuels production. Although the lignocellulosic biorefinery setup has a clear value proposition, the commercial success at the industrial scale is still inadequate. This can be attributed mainly to irregular biomass supply chain, market uncertainties, and scale-up challenges. Global research efforts are underway by public and private sectors to get deeper market penetration. A comprehensive account of important factors, limitations, and propositions are worth consideration for the commercial success of lignocellulosic biorefineries. In this article, the importance of integration of lignocellulosic biorefineries with existing petrochemical refineries, the technical challenges of industrialization, SWOT analysis, and future directions have been reviewed.
