Technology for treatment and secure landfill of hazardous soil and sediments contaminated by PAH, BTEX, TCE, PCE and Hydrocarbons. Signaterre simplifies the disposal of your projects by providing a treatment centre as well as a maximum security landfill on the same site. Treatable soils will be sent to the treatment centre at a competitive price. Non-treatable soils will be sent to a maximum security landfill. BIOVENTILATION: Control of airflow and moisture allows bacteria to decompose some organiccontaminants. CHEMICAL OXYDATION: Controlling the chemical composition of a soil, combined with the controlled application of oxidizing products, breaks down the carbon chains of certain contaminants. EXTRACTION: The passage of air through a soil can extract volatile contaminants. The air is then carboned filtered. SCREENING & GRANULOMETRIC SEGREGATION: Utilized to prepare the soil for a final treatement as required.
