In my area, (Seattle metro area) our county offers a catalog called the IMEX—or Industrial Materials Exchange. This catalog shows all kinds of items that might otherwise be landfilled. Extra paint, tile bits, buckets and containers, etc. I’ve used the IMEX to find items before—but you can also use it to offer items, much like freecycle on a large scale. With IMEX however, there are often nominal fees for the items.
