The most common application for used tiresis as fuel for manufacturing plants. While it does count as recycling, the
process is problematic. Burning rubber releases harmful fumes that cause damage
to the atmosphere. So, it’s not the optimum use for old tires in landfill.
Cleaner, greener applications are taking a long time to catch up, but they are
becoming more widespread.
For instance, some tires are repurposed andturned into hot melt materials for sidewalks. The rubber is either reformed to
make Portland cement concrete or recycled asphalt pavements (also known as
RAPs). Intact tires (not shredded or mulched) are inserted into industrial
cement kilns. Inside, extreme temperatures cause near-instant vaporization.

recycling and disposal businesses rely heavily on networks and relationships
If you’re wondering why used tires aren’treshaped into new versions of the same form – as with paper and plastic – know
that it has been tried. Unfortunately, tires containing recycled rubber are
significantly less durable. As a result, they’re deemed low quality. These
products have a shorter life, a thinner tread and reduced traction. To ensure
road safety, no more than 5% of a new tire can be made out of recycled rubber.
On a smaller scale, rubber can be mulchedand used as a substitute for woodchip in flowerbeds. The pieces need to be cut
up very small, but they are surprisingly good at trapping moisture and fending
off weeds. It’s not uncommon to see recycled rubber in domestic gardens, public
parks and other green spaces.
