Sounds like better definition of what he actually has is needed. Lots of variations since ours do not have any transfer trucks inside just one or two civilian pickups or cars. The buildings are small usually about 50ft sq or so. Once you unload the operators are pretty quick to compact and push it out to the container truck which is outside and adjacent to the perimeter of the building.
There are no HVAC systems in the unloading area, they have a small window unit in the small operator's office. These are used by county residents, no commercial/industrial use is permitted, they must take it to the landfill. Craig L.

They dump municipal trash, which is pushed onto conveyors that ultimately bring it through a wall to be compacted into bales. (Improved efficiency in the loading of the landfill, reduces flying garbage, and sets them up for the day that the landfill is full and they need to haul to another site. We required sprinkler protection within the return air ducts due to anticipated dust loading; protection throughout the tip floor and dump pit required some creativity, because there is no cut-n-dry answer just looking at NFPA 13. A large chunk of the garbage is paper and paper-related items such as box-board, etc. But there are some plastics inevitably mixed in. I looked at FM's guidelines for baled paper, as well as solid-piled plastics - since neither of these fit exactly, I deduced my own scheme. I believe we ended up with 0.3/3,000 using 11.2K sprinklers on 100 sq.ft. spacing. This should work well also for a fire involving one of the larger vehicles you'd see in the building (flat-bed tractor/trailer, garbage trucks, front-end loader-type equipment). This is one of those jobs where it was nice being on the engineering side of the fence, because I don't know how I would have bid it were I in contracting at the time.
