Qualitative Features Of The Waste
A feature of used tire sis that although they are not included among the hazardous waste, their management is difficult so much from an environmental as from an economic point of view.
The large specific volume of the tires make them difficult to transport over great distances, thus making it unviable to recover them in processing units that are situated far away from the areas of their discarding.
Their compact structure impedes any procedure of mechanical processing, significantly increasing the production cost of the final processed products at recycling plants.
The recycling of used tires differs significantly from the recycling of other end of life materials in the sense that products of shredding or granulation of used tires cannot be used as raw materials for the construction – production of new tires except for very small to negligible quantities. The products of used tires processing, however, may become raw materials for the creation of various new products and in some cases replace other raw materials with similar or even better properties.
There is a limited market for these materials in Greece and the rest of Europe. Thus, it is very important to create and develop new markets for the products of processing so as not to create obstacles in the safe management of the waste, given that on the one hand its discarding in landfills has been forbidden since 2003, and on the other its storage for long periods in licensed areas of temporary storage carries risks.
Public works are an important market for many final and intermediate products of tire recycling; these could absorb large quantities of semi-processed (shredded tires) or even crumb or powdered used tires.
