NOTES:

  1. Individual results may vary.

  2. Chipper: approx. 400HP, Diesel fuel consumption: approx. 30 gal/hr. Diesel Fuel at $3.00/gal

  3. It is assumed that chips cannot be reasonably sold for beneficial re-use.

  4. Chipping process and chip handling produces large amounts of particulate matter (PM) in the form of wood dust that can cause serious illness in exposed workers.  Wood dust is a proven carcinogenic (cancer-causing). Chipping losses, mostly in form of wood dust, are approx. 2% or 2 tons in this example. Only 98 tons of wood chips are deposited into the landfill.

  5. Air Curtain Burner residual is 3 tons of ash, hauled by 1 truck, but is usually land-applied on site;  Chipper residual yields no weight reduction, but does provide significant volume reduction.  In this example, waste is hauled by at least 12 trucks, each carrying approximately 22 cubic yards or 5 – 6 tons.

  6. Direct hauling of land clearing wood waste to landfill will require approximately 25 trucks.

  7. The S-220 is a medium size above ground refractory walled firebox.  Larger and smaller models and trench burners are also available.  See www.airburners.com.
