WILL THERE BE A MATERIALS CRISIS?

This paper which discusses the supply of 6 major construction materials (stone sand and gravel, cement, lime, iron and steel, and asphalt), also considers the annual requirements per U.S. citizen, production and consumption data estimates of resources, and factors affecting resource availability. Conclusions are drawn regarding the adequacy of supply and the ability to meet future demands. The new mineral materials required annyally is approximately 40,000 lb. (18 144 kg) per person. Minerals for use in construction and in energy constitute the major fraction of this requirement. Recycling of materials can significantly reduce these requiremnts. Artificial shortages of certain minerals are being created by exhaustion of accessible supplies and factors such as zoing, poor administration, and lack of investment protection. Five primary factors which influence the availability of resources are geology, energy, technology, economics, and law. Comments are made on how these factors may be controlled to minimize artificial shortages in the future. Good resource and environmental management is a prerequisite to an adequate supply of minerals for construction and other applications.
