I envision a Pulp Mill as a versatile biorefinery plant. In recent years, research into its diverse usage capabilities has intensified, particularly focusing on lignin: should we continue burning it, or can we find a better use?
To cut to the chase, as recently published by Nature Magazine, lignin is an excellent candidate for producing Sustainable Aviation Fuel (SAF).
Research institutions like the National Renewable Energy Laboratory (NREL), MIT, and Washington State University have made significant strides in developing continuous processes for lignin conversion, achieving high yields of aromatic compounds suitable for SAF.
This work involves not only chemical engineering but also techno-economic and life cycle assessments to ensure sustainability and economic viability.
If a Recovery Boiler becomes redundant in the pulp production cycle, as lignin is diverted to other processes, the total investment required for greenfield pulp mills could be significantly reduced. Additionally, older mills with aging boilers might shift their processes instead of shutting down.
I wonder if you consider this scenario in your strategic plan.
