Furfural From Sunflower Husks
DESCRIPTION/FEATURES: Based on prior work, two cases were developed (see Beyond Combustion: Additional Value for the Sunflower Husks).
OUTCOME: Depending on the configuration (with or without electricity generation) and location, before tax IRRs are around 30% with a payback period below 4 years.
STATUS QUO: Pellet prices have declined (low coal prices) and furfural production combines with other uses of the lignocellulose is a very attractive alternative.
When we first looked at sunflower husks as a feedstock for furfural production in 2002, the oil mill paid for the husks to be removed. Some mills use (up top 50% of) their husks as boiler fuel. Husks are also pelletised and traded (globally).
