While many biorefineries have a significant focus on producing biofuels, it is possible to use the by-products from such biofuel production for making other valuable products.
For instance lignin, a by-product that gets separated from lignocellulosic biomass during its conversion to ethanol, can be used to make textile fibers. Other portions of biomass or their by-products could also be explored for textile fiber production.
Such valorization has twin benefits: enhances the overall profitability and economics of the biorefinery and enables sustainable disposal of a “waste” stream.
