    AKRON—Green business and economic practices, encompassing both manufacturing and recycling, are crucial to the continuing health and viability of the tire industry, speakers said at the International Tire Exhibition & Conference held in Akron Sept. 11-13.

    The world's population will reach 10 billion by 2058, said Rahinda Mukhopadhyay, director of the Hari Shankar Singhania Elastomer and Tyre Research Institute in Karnataka, India.

    Population growth will be especially intense in India, which will surpass China as the most populous country in the world, according to Mukhopadhyay.

    Along with population growth will come increased economic activity, but also wealth disparity, climate change, increasing societal polarization, rising cyber-dependency and an aging population, he said.

    Because of these factors, auto and tire manufacturers face the challenge of creating new green technologies and expanding the sustainable economy while remaining globally competitive, according to Mukhopadhyay.

    "The green economy means improving human well-being and social equity, while significantly reducing environmental risks and ecological scarcities," he said.

    Climate change already is having a profound impact on Asia, according to Mukhopadhyay. The risks include:

    • Increasing crop failure and lower crop production;
    • Increased risk of heat-related mortality;
    • Increased river, coastal and urban flooding, with increased risk of flood-related deaths, injuries and infrastructure damage;
    • Increased water shortages in arid regions; and
    • Increased risk of water- and vector-borne diseases.

    To reduce these risks, the world must adopt a green economy that turns away from fossil fuels and unbridled consumption toward a focus on saving resources rather than labor, Mukhopadhyay said.

    In terms of tires, this means the development of renewable, mineral-based and recycled raw materials, he said.

    "It is possible to produce a tire with more than a 95 percent non-crude oil base," Mukhopadhyay said. "However, the application range today is still limited."

    Moving toward a green economy in the tire industry, according to Mukhopadhyay, would include:

    • Moving from traditional carbon black to silica and a new generation of nano-fillers;
    • Moving from traditional synthetic rubber to natural rubber, bio-based SR and recycled materials;
    • Moving from polyester, nylon and steel tire cord to vegetable fiber, recycled rayon or thinner, ultra-high-tensile steel cord; and
    • Moving from petroleum-derived oils and chemicals to vegetable oils and substances compliant with the European Union's Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulations.

    A more sustainable vehicle fleet is also vital to achieving a green transportation economy, according to Mukhopadhyay. India is a good example, with a plan that all new vehicles sold within its borders must be 100 percent pure electric by 2047, the 100th anniversary of the nation's independence, he said.

    By 2030, 40 percent of new vehicle sales and all new vehicles for intra-city transport fleets must be pure EV, he said.

    "As vehicles are one of the main sources of air pollution responsible for poor urban air quality, suitable measures should be taken by all concerned to build a green, sustainable future," Mukhopadhyay said.

    The U.S. tire industry is well advanced in its efforts to achieve sustainability, according to John Sheerin, director of end-of-life tire programs for the U.S. Tire Manufacturers Association.

    USTMA members continue to prioritize research into the health and environmental impacts of the manufacturing and use of tires, Sheerin said. They also strive to advance the safety and performance of tires and to manage scrap tires as valuable, reusable materials, he said.

    "We recognize the need to increase the use of sustainable materials," he said. "We are increasing the use of micronized rubber powders, which closes the loop in tire manufacturing."

    USTMA members also are investigating the use of recycled carbon black from pyrolysis, orange and soybean oils instead of petroleum, bioisoprene instead of traditional synthetic rubbers and alternative sources of natural rubber such as guayule and dandelions, according to Sheerin.

    The recycling percentage for scrap tires actually dropped between 2013 and 2017, from 96 to 81 percent of tires generated, Sheerin said. A slight drop in markets plus the sheer increase in scrap tires generated in those years was a major reason for this, he said.

    Nevertheless, scrap tires represent one of the great success stories in recycling, according to Sheerin. "Only lead-acid batteries have a better recycling rate," he said. In one sense, scrap tires have a more impressive track record than lead-acid batteries, because scrap tires on their own have a negative economic value, he said.

    Tire-derived fuel remains the stalwart of scrap tire recycling, accounting for 43 percent of the 3.4 million tons of tires recycled in 2017, according to Sheerin.

    The Environmental Protection Agency has recognized the biogenic content in TDF, in both the greenhouse gas reporting rule from 2010 and the emissions from stationary source rules from both 2011 and 2014, he said.

    Ground rubber accounted for 25 percent of the scrap tire market in 2017, and civil engineering projects for another 8 percent, according to Sheerin. Some 16 percent of scrap tires were landfilled—the highest level in three or four years, because of a decline in the market—and the remaining 8 percent went to various markets, he said.

    "2017 was not a boom year for rubber-modified asphalt," Sheerin said. "But we expect this year to be better, because of new road construction."

    Reduction of scrap tire stockpiles is also a major success story, according to Sheerin. Since the USTMA began its scrap tire program in 1990, the number of stockpiled tires has plummeted 94 percent, to about 60 million from an estimated 1 billion, he said.

    But problem spots remain in several states, either because of bankruptcies among scrap tire processors or lapsed scrap tire abatement programs, Sheerin said.

    In South Carolina, for example, the state faces the cleanup of 800,000 stockpiled tires left by a processor that went bankrupt. The state was allocated $2.7 million for cleanup, Sheerin said.

    Among other states, Colorado has two or three massive tire monofills that the state is required to clean up by 2024, he said.

    "Texas has 17 million stockpiled tires that they know of, and I know of no plan to clean them up," he said. "The state needs a new program."

    Two states—Louisiana and West Virginia—claim to have no stockpiled scrap tires, according to Sheerin.

    "Louisiana has done the work and the cleanups," he said. "The number of stockpiled tires is probably not zero, but the state is very environmentally aware.

    "But West Virginia hasn't done the work," he said. "It hasn't even looked for stockpiles."
