Rubber Recycling

Tire recycling or rubber recycling is the process of recycling vehicles' tires (or tyres) that are no longer suitable for use on vehicles due to wear or irreparable damage (such as punctures). These tires are among the largest and most problematic sources of waste, due to the large volume produced and their durability.

Rubber Imports of Qatar

Rubber consumption has been seen climbing as tire demand grows. According to a report from Southeast Asian research for LMC International, global rubber consumption will grow an average of 3.5 percent a year through 2018 as demand increases for replacement tires, supporting prices of the commodity.

Qatar, becoming the center point for many economic, industrial and development projects, has a remarkable increase of rubber imports in the previous years. Roughly more than 15 percent increase of rubber imports annually. The graph below shows the rubber imports of Qatar from 2005 up to 2010.

 

Solid waste disposal in Qatar

Qatar is generating a total of 28,000 tons of solid waste per day, of which only 3% is recycled, 4% incinerated while the remaining is disposed off into landfills. Solid waste generated has an average annual growth rate of 4.2%.

Qatar has a total land area of 11,571 square kilometers with a population of 2.051 Million in 2012. The annual population growth rate is 7%. On the account of high population growth rate, urbanization, industrial growth and economic expansion, the country is facing serious challenges on solid waste management. Qatar needs to set a solution and strategy on waste disposal in order to reduce the tons of wastes that are generated.

Used-tires disposal

The rise of rubber imports of Qatar added to the challenge on waste disposal. According to Qatar Statistics Authority (QSA), Qatar, on average, imports roughly 913,000 tires a year. Some 488,000 vehicles were registered in the country in 2009, and the QSA said its tire import figures were based on the assumption that two tires were brought into the country per registered vehicle. In 2010, for instance, over a million tires were imported - more than 70 percent of them for automobile cars weighing a massive 36, 140 tons.

According to the QSA, at least 1.9 million used-up tires are discarded as scrap every two to four years, with the virtual age of a tire being about three years. Tire imports have been rising to the extent that from a mere four percent between 2008 and 2009, the increase was more than four-fold (18 percent) between 2010 and 2011. With over a 100,000 new vehicles added to Qatar's roads each year, the imports are expected to maintain an upward trend in the years to come, say experts.
Tire Recycling in Qatar

Used tires are among the largest and problematic source of waste. They are not desired to be at the landfills due to their large volumes occupying wide space. Used tires are mostly not biodegradable and are difficult to compress. They contain components like lead, chrome, cadmium and different chemicals, waxes, oils, pigments, silicas & clays. This means that their threat to the environment is more severe. Ironically though, there isn't much focus on recycling used tires in Qatar, raising more threat to the environment.

FORMEX Tire-Recycling Method

The FORMEX-method uses the pyrolysis process to create carbon black, pyrolitic gas and fuel as new products. The innovative way is using liquid metal to control the process, totally separated from the environment. Depending on the technology variant employed, up to 99% of the material treated is recovered, with virtually no effluents escaping into the environment.

Ecological Aspects of the Method

The mixture of solids contains no toxic substances at levels far below the maximum concentrations permitted by the German Chemicals Act.

The concentration of toxic substances (dioxin, furans, organic tin molecules, etc.) in the pyrolysis oil is below detectable limits or below the permitted concentrations for materials and chemicals in general circulation.

The composition of the pyrolysis gas is such that combustion does not produce more dioxin, furans or polycyclic aromatic hydrocarbons
