This materials flow study includes a description of lead supply and demand factors for the United States to illustrate the extent of lead
recycling and to identify recycling trends. Understanding the system of materials flow from source to ultimate disposition can assist in
improving the management of the use of natural resources in a manner that is compatible with sound environmental practices. The quantity
of lead recycled in 1998, as a percentage of apparent lead supply, was estimated to be about 63%, and recycling efficiency, to be 95%.
Of the total lead consumed in products for the U.S. market in 1998, an estimated 10% was consumed in products in which the lead was
not readily recyclable.
