sunflower husk Sweden

...Sunflower husks are burned as fuel to power oil mills, but only half of the hulls can be used on-site for energy production. The remaining half have to be transported off-site to provide energy or for other purposes, such as composting, bedding material, or as a low-quality roughage for livestock. However, they are light in weight and bulk because of their low density, and are therefore costly and impractical to transport. For sunflower seed oil manufacturer or sunflower seed processors, how to deal with useless husk has become an annoying problem.
