it is the use of whole tires that has drawn Hoenig 's interest, as they can be "baled." Baling is a process in which a loose material, such as cotton or hay, is tightly bound together with wire or cord. The finished product is highly compact. Tires can be completed, too. In fact, there are a number of companies all over the U.S. that bale tires, and Hoenig 's notes that there is one company that actually produces a square tire bale, ideal for building.
