What are the application scenarios for using industrial tire shredders in the circular economy?

 

Industrial tire shredders play a crucial role in the circular economy by transforming waste tires into reusable resources across various application scenarios. Here are some key areas where industrial tire shredders are applied:

 

1. Building materials and engineering applications

Rubber asphalt mixture:Shredded tire particles can be mixed with asphalt to improve the elasticity, wear resistance and noise reduction of the road surface, and are widely used in the paving of highways and high-grade roads.

 

Cushion and anti-skid materials:Rubber crumbs are used in sports venues (such as plastic tracks, football fields), sidewalks, gyms and other scenes to provide cushioning and anti-skid functions.

 

Rubber bricks and floors:Floors and bricks made of recycled rubber have sound insulation and wear resistance, and are suitable for industrial plants, public places and home decoration.

 

2. Rubber product recycling and industrial raw materials

Recycled rubber production:Shredded rubber particles can be processed into recycled rubber, which is used to manufacture tire retreading, sealing strips, brake pads, soles and other products, reducing the consumption of virgin rubber (80% of China's annual demand relies on imports).

 

Rubber powder application:Fine rubber powder (50-80 mesh) is used in industrial fields such as waterproof coils, coatings, and rubber tubes. The cost is only 1/4 of that of virgin rubber, and the market demand is strong.

 

Metal and fiber recycling:After sorting, the steel wire and nylon fiber in the tire can be used as spring steel raw materials or plastic product substrates to achieve full resource utilization.

 

3. Energy substitution and industrial fuel

Tire-derived fuel (TDF):Shredded tire fragments can be used as high calorific value fuel to replace coal in industrial combustion scenarios such as cement kilns and power plants. For example, in one case, 500,000 tons of coal can be replaced each year, significantly reducing carbon emissions.

 

Pyrolysis oil production:Tires are converted into fuel oil or carbon black through chemical processing for industrial energy supplementation.

 

4. Agriculture and public facility innovation

Water conservancy engineering materials:Waste tires are processed into irrigation pipes or flood control equipment, which have both corrosion resistance and low cost advantages.

Environmental protection facilities:Recycled rubber is made into public facilities such as trash cans and park fitness equipment, which have both durability and environmental protection properties.

 

5. Landfill reduction and pollution prevention and control

Volume reduction:The volume of shredded tires is reduced by 70%, significantly alleviating the space pressure of landfills.

 

Pollution prevention and control:Avoid soil and water pollution caused by open-air burning or random stacking, and reduce harmful gas emissions.

 

Industry drive and policy support

Policy incentives:China's "Catalogue of Comprehensive Utilization of Resources" clearly supports the recycling of waste tires, and enterprises can enjoy tax incentives. Regulations such as the EU "ELT Directive" also promote global market growth.

 

Economic advantages:The price of recycled rubber powder is only 1/4 of that of virgin rubber, and market demand continues to grow (the global annual scrap tires exceed 1.5 billion), forming a market scale of hundreds of billions.

 

Typical cases and future trends

China's Shengzhong tire shredder processes 50,000 tons of waste tires annually, which is equivalent to saving 16,000 tons of virgin rubber, with significant economic and environmental benefits.

 

Industrial tire shredders not only address environmental challenges like "black pollution" but also generate substantial economic value, crucial in the circular economy framework.
