If one were to boil this whole process down, it is the system developed to produce the metal type that would prove to be the most innovative.

Soil Conservation. Soil conservation is a combination of all methods of management and land use that safeguard the soil against depletion or deterioration by natural or human-induced factors.
Land Farming involves spreading excavated contaminated soils in a thin layer on the ground surface and stimulating aerobic microbial activity within the soils through aeration and/or the addition of minerals, nutrients, and moisture. It is useful in treating aerobically degradable contaminants (EPA 1994).
