Solid waste management is one of the major environmental concerns in the United States. Over 5 billion tons of non-hazardous solid waste materials are generated in USA each year. Of these, more than 270 million scrap-tires (approximately 3.6 million tons) are generated each year. In addition to this, about 300 million scrap-tires have been stockpiled. Several studies have been carried out to re...

2 Executive Summary The purpose of this paper is to familiarize the reader with the paving material asphalt-rubber (A-R) by providing historical perspective on its development and obstacles to its development. A-R has been a constant and stable market for crumb rubber producers in the United States most significantly within the vicinity of Arizona, California, and Florida. Agencies use A-R beca...

An investigation has been initiated to determine the effects of various atmospheres (6.9% 02iN2, 21 % 02iN2 (air), 30% 02iN2, 3% H2iN2 and pure N2) on the efficiency of gasifying or combusting rubber waste to produce synthesis gas or generate steam or power. This paper reports on the findings from a series of TGA experiments at various heating rates on styrene-butadiene copolymer (SBR), which i...

Tires represent a critical spare part in mines. There is a shortage of medium and large tires. In addition, with increased mining activities and the creation of new mines, the demand for tires has increased significantly. Thus, it is particularly important for mining engineers to identify tire characteristics and correctly manage the spare part inventory. Spare parts management is critical from...

INTRODUCTION Tire explosion injuries are rare, but they may result in a severe injury pattern. Case reports and statistics from injuries caused by exploded truck tires during servicing are established, but trauma from exploded small tires seems to be unknown. CASE PRESENTATION A 47-year-old german man inflated a wheelbarrow tire. The tire exploded during inflation and caused an open, multiple...

Several technologies established for tire utilization were reviewed in order to determine the best use of discarded tires. The technologies reviewed were retreading, reclaiming, splitting, combustion, pyrolysis, use in breakwaters, erosion control structures, reefs, pavements, general construction materials, etc. Based on the information collected, it was concluded that the use of discarded tir...

According to conventional wisdom, rapidly growing stocks of scrap tires on the U.S.–Mexico border pose a variety of health and environmental risks. This article assesses these risks in Paso del Norte, the border’s second-largest metropolis comprised principally of Ciudad Juárez, Chihuahua, and El Paso, Texas. We find that air pollution from tire pile fires poses the greatest threat. Scrap tires...
