Tires
Environmental Impacts of Tires
Manufacturing Tires
Tires contain a lot of metal which are very polluting to extract
Tires contain about 25% synthetic rubber which contains oil and other hydrocarbons that are harmful to environment when extracted
Disposing of Tires
Tires are left in landfills or burned
Burning tires creates a lot of pollution because the synthetic rubber they contain is primary oil/hydrocarbons
50% of tires are recycled
