 General framework |
|||
| In view of the continued growth of the number of motor vehicles in Tunisia and the ensuing huge quantities of used tires added to the pollution they generate, it has become necessary to consider the conversion of such wastes and their utilization as source of income. A technical-economic study on the implementation of a management system was carried out at the end of 2005. | |||
The quantities of used tires in 2005 are estimated at 25 000 tons and will exceed 2 500 000 units in 2025.
|
|||
| Regulatory framework |
|||
| Law no. 96-41 of 10 June 1996, on waste and its management and disposal control. | |||
| Recycling and conversion processes of used tires : |
|||
 Matter conversionCrushing tire waste with special machines; Getting granules of different sizes ; Different possible usages such as in sound-insulated walls, gym floors, civil engineering. |
|||
| Energy conversion Alternative fuel in view of the energy value of tire waste (from 7000 to 9000 kcal, 3 tons of tire equal 2 tons of fuel). |
|||
| Rechapage This technique serves to increase tire life. 12% of used tires (heavy vehicles) are treated through this technique. |
|||
|
|
|||
| Under the Technology Network to Reduce Industrial Air Emissions in the cement sector in Tunisia, and with GTZ assistance, Tunisian cement manufacturers were authorized to import shredded used tires to use as substitution fuel owing to their high energy value. |
5 companies were authorized to recycle used tires.
