Paving the Way for Lignin Valorisation: Recent Advances in Bioengineering, Biorefining and Catalysis

“…The process is maintained at this maximum temperature for 1-2 h, depending on the type of wood feedstock, the desired extent of delignification, and the exact digestion temperature. [202] Throughout the pulping process,i ti se ssential to ensure al iquor pH value > 10, to avoid re-deposition of lignin residues onto the remaining cellulosic fibres. [203] Thed egradation and dissolution of lignin fragments from Spruce wood into the cooking liquor, as afunction of time and programmed temperature,isdisplayed in Figure 4a.…”

Methanogenic Microorganisms in Industrial Wastewater Anaerobic Treatment

“…The toxicity of tannins to methanogens, which depends on the degree of polymerization, has been reported. Effluent dissolved compounds from alkaline peroxide bleaching (5-20 kg/t pulp) consist of carbohydrates (60%), acetic acid, formic acid and methanol (40%) [116]. Very important is the anaerobic reactor configuration.…”

Fate of Lignin in the Process of Aerobic Biological Treatment of Paper Mill Wastewater

“…External standard: Spruce lignin was isolated from a freshly cut spruce tree by means of the Organo-Solv extraction method [12].…”
