• Michigan accumulates about 11 million used tires per year
• They are a public health, environmental and fire hazard
• 1000 chipped tires can be reused in a conventional septic system absorption field.
• 24 cu. yds of tires weighs 9.6 tons V stone at 33.6 tons
• Observations:
1. Tire chips contain carbon black which may be functioning as activated carbon, chemically absorbing trace amounts of organics in wastewater flow.
2. Tire chip metal shards may be chemically binding phosphorus preventing the release of phosphorus to ground water.
3. Tire chips exhibit insulation properties, keeping the bed/trench/wetland warmer than surrounding material, thereby enhancing microbial function.
