As a rule of thumb, the scrap tire generation in industrialized countries is approximately one passenger car tire equivalent (9 kg) per population and year.

The tyre recycling industry has been created virtually due to government regulations enacted to address the environmental concerns about illegally dumped or stockpiled tires.

The pioneers were USA and Japan, The European model starts at 1994 in the Nordic countries.



In the early 1900s, the average recycled content of all rubber products was over 50%.

“Grinding and separation of scrap rubber of all kinds. Low rates. The largest company in the industry. Custom grinding. Specialty: hard rubber dust”

Cost of natural rubber = Cost of Silver (in weight)



Cheap oil imports, the more widespread use of synthetic rubber and the development of steel belted radial tires have led to a steady decline of rubber recycling. It became increasingly difficult to grind or slice old tires.

As of 1995, the traditional tire and rubber industry used only about 2% recycled material.

Technical developments in the past decade make it very likely that the use of recycled tire materials will increase significantly. Rubber recycling not only has a long past, but also a bright future.



Passenger car, lorry and off-the-road (“OTR”) tyres are products of complex engineering.

Tyres are made for their use on vehicles; they are not made as a recycling industry feedstock. Their composition makes them difficult to recycle.



COMPOSITION OF TYRES ON THE MARKET IN THE EUROPENA UNION (by weight)

Material Passenger cars Trucks/buses

Rubber / Elastomers 48% 45%

Carbon black 22% 22%

Metal 15% 25%

Textile 5% -

Zinc oxide 1% 2%

Sulphur 1% 1%

Additives 8% 5%



FOUR MATERIAL CATEGORIES

1. Natural and synthetic rubbers

± 40 - 48% Ratio of natural to synthetic rubber: ± 2 – 1 truck tyres; ±4 – 3 car tyres.

2. Carbon blacks and/or silica ± 22 - 27% A range of carbon blacks of varying sizes, structures and characteristics are used in different parts of the tyre.

3. Reinforcing materials ± 5 - 25%

Metals ± 15 - 25% ± 11 - 13%

In beads, belts and casing of a truck tyre. In casings and plies of a car tyre.

Textiles + 5% Textiles are used in car tyre casings.

4. Facilitators ± 8 - 0% Extender oils, waxes, and plasticizers aid processing;.



COMPOSITION OF TYRES ON THE MARKET IN THE EUROPEAN UNION (by weight)

Category Range Av.wt. Units/t

Passenger car tyres ± 7 – 9kg 8kg ± 125

Vans and light utility vehicles ± 8 – 11g

9kg ± 111

1. Tax System:

The manufacturer / importer is dependent on a government tax

The state is responsible for the operation of the old tire

2. Free Market System:

Each party in the chain is responsible for the fulfillment of the law

All parties shall cooperate in the preparation for the market prices

3. Producer Responsability:

The manufacturers / importers create a "contribution" in the

product sold and are responsible for the management of scrap

tires. Usually cares about an association that is organized by the

manufacturers: an integrated system



The three models in Europe



The tire manufacturers and / or importers are based on the integrated system

The amounts per tire may look like this (example from Norway):

- Truck tires: 5.60, - €

- Car tires: 0.90, - €

- Other than 35, - €



Tire manufacturers inEurope



Management of scrap tire recycling in each country:

Responsibilities of the integrated system

- Certify recyclers

- Distribution of used tires to recyclers (usually every two years for tenders)

- Collector of contributions with the tire manufacturers

- Control of inputs and outputs of waste tires in each country: everything produced or imported, must be 100% recyclable and can no longer be landfilled



1. Collection of used tires

Expiration of the recycling chain

2. Sorting of tires



3. Shredding and separation of rubber, steel and textile.

4. Fine grinding of the rubber tire and sale of various products produced.


Expiration of the recycling chain

The scrap tire industry is driven by regulation.

Timing of regulatory introduction dictates the current state of development.

USA and Japan have the more developed end product market, but Europe is rising quickly .

Russia and Australia seems to start on regulation programs, incipient industry.

South America, Asia and Africa are in developing stages

Profitability of the industry remains the most immediate concern.
