This is an informative video demonstrating the Midwest Soil Remediation high capacity direct fired thermal desorption system; and contains footage of the system as it processes contaminated materials. Illustrations and animations further explain the inner workings of the equipment, while a narrative describes the capabilities and practical applications of the process.
There is very little nutritional value left when it is burnt, but most of the soil that is being burnt is clay, sand, rock. So there is not that much to start off with. At for the contaminates they enter a oxidizer (afterburner) which runs at about 1550F which will destroy 99% of hydrocarbons at that temperature. All that is produce is CO2 and water vapor. I know co2 is not the best but it is better then the contamination leaking into the ground water.

--It provides a clean, usable "process material", this is the point. This product is not soil it is a "process material"... might be very good to asphalt roads but it isn't soil anymore. They also could explain where the extracted organic contaminants are going to... to the lungs of the employees that work there... I guess. This might be very harsh working environment.

I believe to have read 1994 in the beginning titles... in fact this is a prehistoric concept of soil remediation. Forget it.

This is one expensive way to clean soil but I have to believe the hydrocarbons still escape into the atmosphere. Now after you have burned the soil and all existing nurtients are gone, what value does the soil have now? Why not wash the soil with microbes? It would be cheaper and much safer and your end product would be reusable healthy soil.
