Abstract
A life cycle thinking analysis (LCT) conducted on the production of vanillin via bamboo wet air oxidation compared to vanillin production from crude oil or kraft lignin.
Highlights
An increasing effort is devoted to find processes for the conversion of biomass and biomass-derived products into fuels and organic chemicals,[1] which is in part driven by the United Nations Sustainable Development Goal 12 (SDG 12) for Responsible Consumption and Production.[2]
Life cycle thinking (LCT) is an approach, similar to life cycle assessments (LCA), that is utilised to assess the green credentials of a process by considering various synthesis routes.[7,8]
A possible explanation for this is that at the highest alkaline levels, complete mineralization of the intermediates is taking place with the aldehydes being converted into CO2 and H2O when the available, more reactive lignin substrate has been exhausted and further oxidation becomes the dominant process
Summary
An increasing effort is devoted to find processes for the conversion of biomass and biomass-derived products into fuels and organic chemicals,[1] which is in part driven by the United Nations Sustainable Development Goal 12 (SDG 12) for Responsible Consumption and Production.[2]. CuSO4 and Fe2O3 are effective catalysts for reasonable overall bio-oil yields and report good selectivity to aldehydes, syringaldehyde.
