Tires

The production and disposal of tires involve several complex processes and environmental considerations. Tires consist of various materials, including synthetic rubber, which contains oil and hydrocarbons, metals, and other substances that pose environmental hazards when extracted.

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
