Donjon has provided pollution control and abatement services since its inception, in conjunction with its marine salvage service. We have dramatically expanded our total capability by diversifying into handling, treatment, and disposal of hazardous material. With our sister companies, Clean Venture, Cycle Chem, and DEMS (Donjon Environmental Marine Services), we now provide "cradle to grave" services for materials generated by both land and water based salvage and related operations. Through our affiliation with Clean Venture and Cycle Chem, we operate a fully-permitted transfer-storage disposal facility (TSDF) and provide expert services in the areas of:

• 24-hour emergency petroleum spill response
• 24-hour Hazardous Materials Response and Disposal
• Tank testing and Cleaning
• Vacuum Truck Service
• Heat Exchanger and Line Cleaning
• Water Blasting to 10,000 psi
• Transformer Decommissioning and Scraping
• Ground Water Pollution Monitoring
• Site Well Drilling and Water Analysis
• Solvent Recycling
• Chemical Detoxification
• Site Decontamination
• Secure Land Burial

Our efforts to expand our range of casualty response services to the marine community have culminated in the creation of Donjon Environmental Marine Services, LLC (DEMS). DEMS is a USCG certified Oil Spill Response Organization (OSRO), for the inland, near-shore and open ocean environments for the U.S. East and Gulf Coasts.

The company was formed in 1995 with the goals of fulfilling the planning requirement placed on the tank-vessel and facilities industries, as well as providing a timely, professional, experienced and cost-efficient casualty response. DEMS response resource summary includes trained personnel; skimmers, boom, vessels and storage capacity to combat a worst discharge of pollution.
