Free Used Tires
Even though we all love brown new tires on our cars, used tires are still valuable and marketable as ever, especially in developing countries where the business of second-hand tire is very lucrative. Tyre recycling is the process of recycling vehicles’ tires that are no longer suitable for use on vehicles due to wear or irreparable damage. These tires are among the largest and most problematic sources of waste, due to the large volume produced, their durability, and the fact they contain a number of components that are ecologically problematic. The same characteristics that make waste tires problematic, their cheap availability, bulk, and resilience, also make them attractive targets for recycling. Nonetheless more than half of used tires are simply burned for their fuel value. Although tires are usually burnt, not recycled, efforts are continuing to find value. Tires have also been cut up and used in garden beds as bark mulch to hold in the water and to prevent weeds from growing. Some green buildings, both private and public, have been made from old tires. Pyrolysis can be used to reprocess the tires into fuel gas, oils, solid residue, and low-grade carbon black, which cannot be used in tire manufacture. Recent developments in devulcanization promise to deal with substantial volumes, taking 40 mesh whole tire crumb and converting it into what is proposed to be value-added materials. This new generation in devulcanization technologies operates with very high productivity while maintaining a low energy footprint. The compounds produced from processed tire scrap can be blended with virgin rubber compounds, maintaining performance while substantially reducing the raw material cost. The substantial economies of scale and value addition now make it possible to make burning of tires entirely unnecessary. Used tires are still hot cakes in most developing countries, making it hard to get freely. But several companies are braking through, and offering free used tires to people who needed them. Simply browse through the links and follow the instructions on how to get them without spending a dime.
