One recent example of industrial hyper growth has taken place in the recycling industry, led by the rapid expansion of the recycled paper market. Though many laws were enacted in the late 1980s to encourage (and in some cases require) the collection of waste paper for recycling, there were not, at that time, companies with sufficient capacity to recycle it all. Consequently the collected paper accumulated in storage, usually at the expense of the recycling companies, thereby adding to their overhead and squeezing their already thin profit margins.
Today a different situation exists. Fifty-seven new paper mills have been built since 1991, and of these, at least twenty-nine use recycled fiber. This surge in capacity has resulted in a concurrent rise in profits. The price per Ton of waste paper has quadrupled in the past year, as have the prices of corrugated cardboard and used newsprint. Trash haulers have benefited from these conditions by combining their trash hauling and recycling operations.
Recycling centers are connected both to the clients to whom they sell end-products and to those from whom they collect refuse; thus, the company gets paid twice for the same trash, once for hauling the waste and once for selling the usable material. Industry profits have increased more than tenfold during this period. As the industry has become more competitive, some haulers have chosen to rebate a portion of this money to their clients in the hopes of ensuring their loyalty.
