To your first point. Huan scent is not chemically or physically bonded to the activated carbon. On a molecular level activated carbon is basically millions of caves in which scent molecules get "lost" and as they proceed down the caves get "stuck" until the cave fills up. The drying process, and I am going to confirm the scientific name for this, heats the molucules causing them to move and work their way out of the caves. During the first ten minutes or so of a drying cycle with activated carbon in it, the activated carbon is adsorbing scent from the dryer. After this time the airflow and heat reach a point to where this scent being exhumed and exhausted out the vent. Yes, some stays in there and will be adsorbed by the garment again. This accounts for part of the 10-15% that stays in the garment.
Still on your first point, the reactivatiion process (using high heat etc.) gets rid of compounds that have bonded with the activated carbon. Again, this is taken into account for in the 10-15% number.
To your second point, activated carbon has been tested around the world for water filtration, chemical filtering, insoles, and an array of other scientific and commercial industries. These are industries that are completely independent of ours and their testing data shows that activated carbon can adsorb odor and molecules. The testing data shown in the graph is funded by us at a third party laboratory. We cannot show you that actual data as there is confidential information about other technologies in it, even other techologies in this very industry; but showing that data could hurt our partnerships in the long run. I am checking with our lawers to see if I can post the lab, as their may be confidentiality issues, don't count on it though.
However our tests were performed using the Headspace GCMS system to assay odorous compounds after equilibration with various textile substrates. We used an Agilent 6890A gas Chromatograph equipped with an Agilent 5973 Mass Selective Detector, a Leap Technologies Combi Pal Autosampler and a Phenomenex 30m x .53 mm ZB-5, um film column. A 22 mL headspace vials with Teflon-sealed septa. A human scent cocktail containing a mixture of trimethylamine, dimethyl sulfide, isobutyraldehyde, ethanol, isovaleric acid, and limonene. This kind beats non-regenerated suits in a field and boxes huh? javascript

Third point I think I addressed as we pay for some and some are independent, but Oaklahoma State has done a lot of testing on this subject as well as many other labs around the world.
Fourth point, the effect you are referring to is not compounded on top of each other. Like a sponge water molecule A,B,C go into a sponge. Wring out Molucule A & B and wipe up more molecules D,E. Wirng out again and molecules C & E are then wrung out leaving now only molecule D. After proper regeneration, 10-15% of total capacity will be filled up, leaving 85-90% to use.
Lastly, the "scientific" study you referred to before has a lot of holes. How old are the suits, how many washes, how were they reactivated, what type of footwear were the subjects wearing, where did they walk before getting into the boxes, did the ATV that took them to the box leave any scent, who lifted the box over the subjects head, were they wearing gloves, what did they touch before they lifetd the boxes. All of these things directly add scent to an area and were not accounted for in the "scientific" test.
