Vanillin derived from lignin liquefaction: a sustainability evaluation

Life cycle thinking case study for catalytic wet air oxidation of lignin in bamboo biomass for vanillin production

“…3 Conducting an LCA as part of a new process analysis has become more prevalent with the availability of LCA software and environmental databases. 4,5 The benefits of LCA are the identification and quantification of impacts of particular processes or compounds to the environment allowing for adjustment of the process as to be more environmentally by design. This is a change from previous modes whereby the processes were shown to work, scaled and then an effort was made to mitigate against environmental impact.…”

“…Quantification of more environmentally friendly vanillin production processes have been reported previously through LCA. Isola et al 4 reported a quantified method to lower environmental impact of alkali lignin depolymerisation with vanillin using MoO, Lao and CoO catalysts. Wongtanyawat et al 5 reported a quantified environmental impact of process design, including solvent selection, for the production of vanillin using LCSoft.…”

Vanillin-based thiol-ene systems as photoresins for optical 3D printing

“…Vanillin is currently one of the only biobased and aromatic compounds that are industrially available (Fache et al, 2015). Mostly it is obtained by extraction from the beans of vanilla orchid (Dong et al, 2014) or by chemical modification of lignin, which is the second most prevalent biopolymer (Isola et al, 2018). In the past years, vanillin and its derivatives have been used in polymer synthesis as their aromatic resins provide the high rigidity and thermal stability of resulting polymers Stanzione et al, 2012).…”

A kaleidoscopic look at vanillyl alcohol oxidase

“…[273], and a product of lignin pyrolysis [274,275]. Vanillin production from lignin or wood [276,277] could therefore profit from using VAO. Unfortunately, the reaction of VAO with p-creosol is severely hampered by the formation of a covalent adduct between pcreosol and VAO's FAD cofactor [45].…”
