  • Tire Shredding: Alternatives to Landfills

    For many reasons, whole tires pose a major problem to landfills. The most obvious is the inefficient use of space. The actual rubber of a tire takes up only a small fraction of the space a tire occupies, and the rest of the space is wasted. A less obvious but far more serious problem is that tires may trap methane gasses when buried with other garbage in landfills. When this happens, the tires ...

    From cars and trucks to planes, tractors, and forklifts, tires are used for a wide variety of vehicles. And those tires don’t last forever.

  • How Tire Shredding Protects Wildlife

    One of the most revolutionary inventions in the history of mankind was the wheel, and the best upgrade to that invention was the rubber tire, which overcame the limitations of wooden or metal wheels and made it possible to have smooth rides at fast speeds. However, there is a significant drawback to using rubber tires: eventually, they get too worn out to be useful as tires anymore and have to ...

  • UNTHA – specialists in RDF and SRF shredding

    Prevention of waste at source is obviously the preferable scenario, but for as long as households continue to fill their bins with rubbish, for as long as companies dismiss the duty they have to reduce the waste they produce, and for as long as countries continue to burn fossil fuels for energy, nations must look at smarter ways to utilise their waste. Companies involved in the engineering and ...
