Why burn what you can reclaim?
Thermal Desorption uses heat to separate contaminants, elements, etc. from the soil through vaporization. Incineration uses heat to destroy these contaminants-along with any other valuable commodities within the feed stock. Most current thermal technologies are incineration based and simply burn off any hydrocarbon content in the waste matter. An incineration process has a number of serious drawbacks that include but are not limited to:
Failure to recover a valuable commodity
Production of greenhouse gas emissions
Resultant biologically dead soil product (often requiring costly disposal)
