    Ever wondered about the tyres that are no longer roadworthy after they are used? They are stockpiled, dumped in landfills, or just thrown away on roadsides. This linear product use approach results in a massive waste. Tyres, whether it is electric, solar powered, gasoline, or hydrogen fuelled vehicle, are indispensable components for the transportation industry. Scrap tyres have potential to harm local environments and negatively affect human health. The most common problems associated with waste tyres are open-air fires and the creation of breeding ground for rodents and mosquitoes. It’s bad but it’s a fact. According to The Freedonia Group Report it is estimated that the world demand for tyres is forecast to rise 4.7 percent per year through 2015 to 3.3 billion units. Approximately same amount of tyres are disposed of every year and almost 20% of them are illegally dumped in landfills, or just thrown away on roadsides. Is this the end of the story? No, these approaches can ultimately lead towards right environmental choices and would make good financial sense. Circular Economy The alternative to the growing waste concerns is to develop a circular economy, which goes much further than recycling, and there is a strong business case for development. Building recycling industries to recover, recycle and process the waste tyres – with the focus on the reduce and reuse principles, unemployed people can find gainful employment, SMEs can be developed and, the environmental disaster that waste tyres represent can be economically and effectively addressed. Analysis by McKinsey estimates that shifting in this direction of circular economy model could add $1-trillion to the global economy by 2025 and create 100 000 new jobs within the next five years. It’s worth it! Energy A normal used passenger car tyre weighs 7.2 kg; it contains at least 238 MJ of thermal energy, which can be useful in some dedicated facilities. In thermoelectric plants, tyres are fed into the hearth without any pre-treatment or slicing. This process is an economically viable alternative for used tyres that cannot be effectively re-treaded, generating a large amount of by-products. Each ton of input (as tyres) generates 287 kg of solid residue made of zinc oxide, ferrous slag and gypsum, each with a well-defined market. The use of old tyres as fuel has the advantage that it does not generate any waste beyond...
