Bacterial valorization of pulp and paper industry

2021-1-22  Black liquor is a byproduct of the Kraft pulping process used in the pulp and paper industry. In this process, pretreated wood is digested using sodium hydroxide (NaOH) and sodium sulfide (Na 2 S) at a pH range of 13–14, which creates brown stock and black liquor (Fallavollita et al. 1987; Naqvi et al. 2010). These streams go through a multistage screening and washing process.

In general, the softwoods (e.g., pines, firs, and spruces) yield long and strong fibers that impart strength to paper and are used for boxes and packaging. Hardwoods, on the other hand, generally have shorter fibers and therefore produce a weaker paper, but one that is smoother, more opaque, and better suited
