145.3 thousand tons 2 of total asbestos consumed in 1985 for all product categories. Table 1 lists the total number of plants and the estimated gallons of coatings and cements produced in 1985. There are no importers of these products (ICF 1986). Asbestos containing roof coating and cement production was estimated to be 76 million gallons. At an average price of $2.49/gallon, this market is estimated to be worth $189.2 million (ICF 1986). C. Trends The number of asbestos-based roof coating and cement manufacturers declined steadily from 1981 until 1985. During those four years 13 companies (30 percent), formerly producing asbestos containing roofing compounds, either substituted asbestos with other materials or discontinued their operations. In 1986, 14 of the 31 companies remaining in 1985, accounting for more than 24 percent of 1985 output, ceased processing asbestos because of rising insurance premiums, customer pressure to remove asbestos, and the possibility of regulatory action (ICF 1986). D. Substitutes Asbestos is unique among known raw minerals because it is a chemically inert, durable mineral that can be processed into a fiber. By partially adsorbing the asphalt into which it is placed, the fiber becomes an integral component of the mixture without settling or floating. The addition of one pound of asbestos fiber per gallon of thinned asphalt (only 10 percent by weight) imparts a large degree of body and turns the liquid into a soft paste. Industry leaders indicate that they have been unable to find a substitute for asbestos that can simultaneously reproduce the numerous qualities of the 2 145.3 thousand tons of asbestos fiber is the ICF total. The Bureau of Mines (BOM) total is 172 thousand tons. Therefore, asbestos fiber used in roof coatings and cements (accounted for by ICF) will be 17 percent of the BOM total. -3-
