Sunflower Husks and Furfural
Some years ago when we first investigated the use of sunflower husks, we found oil mills that paid for them to be taken away ..
.. and they used coal to generate the process steam. Since then, husks are often used to fuel the steam boilers. However, there is always an excess of husks. Some oil mills pelletise and export them. DalinYebo has done extensive work with sunflower husks as part of IFT's furfural process developments. We have found that sunflower husks are indeed a suitable feedstock for furfural production. It was used in one of the USSR biorefineries (hydrolysers) as feedstock to make furfural.
Once the furfural is extracted, the remaining lignocellulosic residue can either be pelletised or further processed, as it has many value-added uses.
Furfural production adds value to sunflower husks, beyond combustion. Although its pentosan content is lower than that of corncobs, it has many advantages: Generally it is available at a central location 24/7 for 365 days per year (oil mills have large seed storage), it is dry and handles beautifully.
