Current Status of Waste Tire Recycling
Massive Generation: The global production of waste tires is enormous, with China alone generating over 10 million tons annually.
Improved Recycling Rates: Developed countries have high recycling rates, such as over 95% in the EU, while China achieves around 60%-70%.
Policy Support: Governments worldwide are promoting recycling through legislation and policies, such as China's Law on the Prevention and Control of Environmental Pollution by Solid Waste.
Technological Advancements: Recycling technologies, including pyrolysis and shredding, are continuously improving, enhancing resource utilization efficiency.
Utilization Pathways for Waste Tires
Retreading: Extending tire lifespan through retreading to conserve resources.
Reclaimed Rubber Production: Processing waste tires into reclaimed rubber for manufacturing new tires and rubber products.
Pyrolysis Treatment: Extracting fuel oil, carbon black, and steel wire through pyrolysis for industrial and energy applications.
Shredding and Reuse: Crushing tires into rubber powder for use in running tracks, sports fields, and more.
Energy Recovery: Using waste tires as alternative fuel in cement plants and power plants.
Construction Materials: Producing rubber asphalt, soundproofing materials, and other building products.
Creative Reuse: Repurposing tires for art installations, furniture, and other innovative applications.
Conclusion
Waste tire recycling is steadily improving with the support of policies and technological advancements. Through retreading, reclaimed rubber production, pyrolysis, shredding, and other methods, waste tires are being transformed into valuable resources, reducing environmental pollution.
