The Importance of Recycling Used Tires

The recycling of used tires has emerged as a crucial environmental and economic issue in modern society.
Every year, millions of discarded auto and motorcycle tires accumulate, presenting a significant disposal challenge as well as a unique opportunity for reuse.
When disposing of tires, strict regulations must be followed, as we will discuss.

Beyond disposal, old tires can be transformed into creative treasures, offering new life as furniture or various other objects.
Creativity is key to this process.

Why Recycle Tires?

Tire recycling is vital for both the environment and the economy.
According to Emissions Analytics, nearly two billion tires are produced annually, an unsustainable number without the proper recycling chain.
Here are key reasons to address unused tires:

Environmental Impact

If inadequately managed, used tires can release harmful substances such as zinc, benzene, and lead, polluting soil, water, and air.
Recycling tires reduces landfill waste and prevents hazardous fires, which can cause significant environmental damage.
Additionally, tire recycling helps lower CO2 emissions.
In the past decade, Ecopneus reports that 2.2 million tons of used tires have been collected in Italy alone, preventing 3.36 million tons of CO2 equivalents from entering the atmosphere.

Value of Raw Materials

Tires are composed of valuable materials that can be recovered and reused.
The rubber material is a high-quality polymer blend that retains its properties even after recycling, producing rubber, steel, and textile fibers for various industries.
In Italy, annual savings of 22.6 million liters of oil and 16,600 tons of strategic raw materials have been achieved through tire reconstruction.

How to Properly Dispose of Tires?

The management of used tires is governed by specific laws.
In Italy, Legislative Decree No.
82 of April 11, 2011, regulates disposal practices, enforcing strict rules for sustainable management.

Producers and importers must manage a quantity of used tires equivalent to those sold the previous year, promoting recycling and material recovery as part of their extended responsibility.

Specialized operators, such as mechanics, are required to collect and ensure the proper disposal of old tires when replacing them.
Since 2011, disposal costs have been paid by buyers as an additional charge during the purchase of new tires, usually around 3 euros per tire.
This fee varies by manufacturer and ensures that costs are covered at the point of sale, thereby deterring illegal disposal.

How Are Used Tires Recycled?

The recycling process involves several key steps to turn waste into precious resources, significantly reducing environmental impact:

Collection and Selection

The first step involves collecting used tires; Italian law mandates recycling for 95% of discarded tires.
Mechanics and repair shops are obligated to handle this collection.
Specialized centers welcome citizens to drop off their old tires.

Shredding

Shredding is central to tire recycling.
Tires are first reduced to smaller pieces using specialized machinery, progressing from coarse grinding to finer particles, ultimately producing granules or rubber powder.

Material Separation

During shredding, the tires’ materials—mainly rubber, steel, and textile fibers—are separated.
Steel is extracted using magnets for recycling, while textile fibers can serve various industrial purposes.
The outcome is granulated rubber ready for diverse applications.

Products from Recycling

The extensive recycling of used tires opens up various opportunities for innovative and sustainable products, with categories ranging from rubber flooring to urban furniture:

Rubber Pavements

Rubber pavements, known for their durability, are perfect for play areas, sports fields, and athletic tracks, enhancing safety and performance.

Modified Asphalt

Recycled rubber powder is added to traditional asphalt, creating resilient, quieter road surfaces that enhance urban living quality.

Urban Furniture

Recycled rubber finds its way into outdoor furniture like benches, flower boxes, and safety measures, proving that sustainable materials can elevate public spaces.

Creative Ideas for Home Reuse of Tires

Recycling does not just apply to industrial uses; various home projects can creatively repurpose auto tires:

From furniture like poufs and garden planters to outdoor seating and unique kitchen accessories, the possibilities are endless.

The Future of Tire Recycling

The tire recycling market is growing, projected to reach $46.9 billion by 2030.
Italy manages about 499,000 tons of used tires annually, demonstrating both progress and challenges, particularly in using rubber powder in asphalt.
