Wow, who writes this stuff?
I think "low input” means “low energy input” technologies. They are trying to develop more efficient ways to separate biomass components by studying how particle size, shape and density affect the separation process.
This quote “A UT survey showed similar concepts cutting across a range of separating actions. Pneumatic, gravity, and imaging exhibit the greatest potential." seems to say that they have noticed some common characteristics (which is a good thing) between the various separation technologies with the three listed showing greatest promise.
It seems to me that all this may refer not so much to the study of the KDS, but more to the study of the product from the KDS. Remember that this was the hold up at AP - what to do with the dry product. I think this quote confirms that “...Improved physical separation of biomass concentrates higher value components, returns unused plant components to soil, decreases bulk for wet separation processes, decreases drying energy, and improves transportation and use of a voluminous, chemically diverse feedstock...” That's what seems to interest them.
