2. Vanillin production from lignin
2.1 Lignin depolymerization
The process of obtaining vanillin from lignin (lignin-to-vanillin) dates back to the early 1930s. Today, as mentioned above, only 15% of total vanillin production comes from lignin . More precisely, it comes from lignosulfonates, mainly from the Norwegian company Borregaard, which has been operating a lignin for vanillin plant in Sarpsborg, Norway, for over 50 years. For the past 20 years, they have been the only company...
