Sacré-Davey worked with Sonic Environmental to scale up their PCB destruction process. Sonic’s novel process recovered PCB’s from contaminated soil using mining technologies. Sacré-Davey floated contaminates from the soil into a liquor, allowing clean soil to be returned. The subsequent PCB-containing liquor was destroyed using Sonic’s proprietary Sono Process. Sacré-Davey provided all engineering, project management, and start-up services.
