The five factors of the Soil Profile - soil type, moisture content, contaminant type, contaminant level and clean-up criteria - all vary from project to project and will greatly effect the speed and the temperature of the KM-4. As a result, the Soil Profile must be careful assessed before estimating the operating costs of any site clean-up.

The cost of fuel is the largest single expense in a thermal remediation project. Often this is the difference in choosing between thermal desorption and landfilling.

A typical thermal desorbers uses 40 liters (11 US gallons) of fuel per ton to heat the soil, volatilize the hydrocarbons and soil moisture, and further heat the airstream to convert the hydrocarbons into water and carbon dioxide.

For the same throughput, the KM-4 uses 20 liters (5 US gallons) of fuel per ton.
The annual fuel saving based on 100K tons of throughput, is 2 million liters (520,000 US gallons).

Therefore, if the Enviro-Klean KM-4 design meets your remediation requirements, the fuel savings more than recover the capital cost of the equipment within just a few years.

And together with the KM-4`s portability and ease of operation, these fuel savings have the potential to create soil remediation opportunities that were formerly too large or costly to manage.
