    It's a 9 nation EU-financed project.
    Old tyres, which mostly are dumped into landscape, are turned into silicon carbide, which sells for 10,000$ a tonne.

    Also 6 KiloWatt energy are extracted by 1 Kilogram old tyres. Which is same energy efficiency as coal. 6 Kilowatt can power 2 flats of a building (the scientist in podcast explains).

    About 242 million tyres are discarded each year in USA.
    7% are recycled, 11% burned, 5% exported.
    Rest is filled into landscape.

    Silicon carbide's natural occurence is in interstellar stardust.
