Recyclers of Used Vehicular Tires

Introduction

Used tires, because of their properties is the product not in principle suitable for burial. Tire contact with rainfall and groundwater leaching is accompanied by a number of toxic organic compounds, diphenylamine, dibutyl phthalate, phenanthrene, etc. All of these compounds into the soil. Decomposition of tires in the ground lasts for more than 100 years. Form tires and specific weight due to cavitation (the formation of voids) do not allow the regulated landfill compaction. Lack of control over waste burning, spontaneous combustion (e.g. due to lightning) lead to prolonged fires at landfills that are good for flammability (combustibility) tire difficult to put out. In 90 years this has led to devastating fires in landfills of tires in the United States and Canada, where only in Ontario during the month burned more than 12 million tires.

In the worn-out car tires because of their shape is going to rain water. Black tire leads to their intense heat under the influence of sunlight, which is stored in the rubber over time. Thus, the tire dump forms an ideal breeding of parasites, for example mosquitoes etc. Due to the fact that these insects can transmit disease, landfills are danger to human health. Adversely affect tire dumps and the landscape. Extensive dumping waste tires in the last decade leads to a shortage of available landfill space. In the event of a further continuation of dumping tire size for them will soon be exhausted. Create new burials can be allowed only in limited quantities or not at all allowed, primarily due to the increase of environmental consciousness.

Environmental aspects of waste pneumatic tires

British and Swedish experts conducted a study which found that the tires - a rather dangerous part of the car: the dust that arises as a result of tire wear can cause serious disease. For example, in Sweden alone is released to the atmosphere each year around 10 000 tons of rubber dust. In Los Angeles, every day is thrown around 5 tonnes (and this despite the fact that Los Angeles is considered environmentally friendly city). And just as in the whole world, the amounts of these emissions are more than 1 million tons. By simple calculations Swedish researchers found that every day an ordinary citizen of Sweden inhales 6 grams of rubber dust, and American.

Contact tire rainfall and ground water leaching followed by a number of toxic organic compounds: 1 - (3-methylphenyl) ethanone, azulene, benzothiazole, 2-methylbenzothiazole, N-(2,2-dimethylpropyl)-N-metilbenzamin, butylated hydroxytoluene , diethyl phthalate (has pronounced cumulative properties), 2 - (methylthio) benzothiazole, diphenylamine (class 3), dibutyl phthalate, phenanthrene (class 2-carcinogenic in mice). Furthermore, there is a group of organic substances which cannot be assumed in advance as in the various countries in creating automobile tires may be used various plasticizers, softeners, etc. substance. Non-toxic organic substances come across among them are extremely rare (Hundal, 2000).
