According to John Sheerin, director of waste tire recycling projects at the U.S. Tire. ers Association, tire derived fuels and rubber modified asphalt are key growth areas for tire disposal and recycling.
However, the market dominance of auxiliary fuels and rubber asphalt is not clear. The waste tire report issued on July 18, 2017 recorded the progress in the reduction and final use of waste tires in that year.
For example, in 2017, 81.4% of waste tyres produced in the United States reached the end-use market. Compared with 95% in 2013 and 87.9% in 2015, the utilization rate of used tires has been decreasing, mainly due to the increasing use of tire disposal & recycling. According to the report, in 2017, it grew by 4% to nearly 4.19 million tons. According to the report, auxiliary fuel is the largest scrap tire market in 2017, accounting for 43% of total tires. Sheerin said that economic factors have led to a decline in demand for auxiliary fuels, but they also have created hope for the future of the market.
As the demand of newspaper and magazine publishers declines, the demand for auxiliary fuels in the pulp and paper industry declines. In utilities, auxiliary fuels must compete with low-cost natural gas. On the other hand, the demand for auxiliary fuels in cement kilns is also growing steadily. "The demand in the construction market is very strong." "The cement industry uses more auxiliary fuels than ever before," Sheerin said.
In addition, rubber asphalt technology and changes within the state highway sector are helping the material gain recognition. For decades, rubber asphalt has gained a bad reputation as a result of the Intermodal Ground Transport Eicince Act of the early 1990s. For many years, most state highway departments have been reluctant to use rubber asphalt.
You should know that rubber asphalt is more durable and economical than traditional paving materials, but it is more vulnerable to be damaged. "The new face is seeing changes in technology, not saying,'We tried, but we didn't succeed'," Sheerin said.
In recent years, due to environmental problems, sports venue covers and sports venue fillers have attracted much attention, especially NBC News reports in 2014 and 2015, which link rubber debris on the sports venue with an increase in cancer incidence among young female athletes. However, according to Sheerin, these concerns seem to be dissipating.
