Turning back to the south we can see the doors of the shipping bays. There are 102 of them.
In the foreground below are recycling bins. Donaldson's recycles as much as it can, thereby cutting its disposal costs. Before it began aggressive recycling, it was filling a dumpster or two each week. Now it fills a dumpster in about six months.
About ten trucks a day depart for overseas destinations. The trucks travel to Chicago, where the containers are put on trains for either the West or East Coast, and from there to ships. My guide pointed out special packing material to keep the load secure for a boat trip that might not always be smooth.
At the very south end of the building recycling materials were being packed up for shipment out of the plant. Donaldson's sells metal to Rensselaer Iron and Metal--you can see one of their blue dumpsters below. They also have to dispose of damaged or outdated product, and this they give to a dealer that will shred it and sort it. I was surprised to learn that filters are like food--they have a sell-by date, which is usually about four years after manufacture.
