This invention describes a process for the depolymerization of lignin under mild oxidizing conditions, which does not produce highly acidic or basic waste-streams and is particularly useful for making aromatic aldehydes such as vanillin and syringaldehyde. Oxidative depolymerisation of lignin into low molar mass compounds that can be used in the chemical industry, as an alternative to chemicals derived from non-renewable feedstocks.
This technology is patented via PCT
The method was found successful for the defragmentation of KRAFT lignin and Lignosulphonate to form valuable low molar compounds. Innovus is looking for industrial partnerships to commercialize the method.
