Non-Haz Waste

Clark Environmental, Inc. accepts difficult materials such as tank bottom sludges. Sludge is our specialty!

Home | Non-Haz Waste

Clark Environmental, Inc. owns and operates a FDEP permitted waste solidification facility processing non-hazardous solids, sludges, liquids, tars and gels in both drum and bulk quantities. Depending on the contaminates of the materials, it will either be processed through our Thermal Treatment Facility, disposed at an approved FDEP -Class I landfill, or processed through a FDEP permitted wastewater treatment facility. Clark Environmental, Inc. also handles spill cleanup absorbents (booms, pads, filters etc.) contaminated PPE, along with off-specification and unused product. Additionally, we handle empty drums and containers for recycling. Certificates of Acceptance, Treatment and Disposal are also available on request.
