The invention comprises a process for remediation of soil comprising PFAS. The process comprises steps a)-d). In step a) sludge and a first gaseous stream are heated in a first spouting bed incinerator, thereby generating a raw material for a ceramic article and a first gaseous stream comprising a first flue gas, the first gaseous stream comprising the first flue gas having a temperature of at least 800 C. In step b) the first gaseous stream comprising the first flue gas is heat exchanged with a second gaseous stream in an air-to-air heat exchanger, thereby generating a second gaseous stream with a temperature of at least 500 C. In step c) the soil comprising PFAS is contacted with the second gaseous stream in a dryer, thereby evaporating the PFAS from the soil and generating clean soil and a second gaseous stream comprising PFAS. In step d) the second gaseous stream comprising PFAS is further heated to a temperature of at least 1000 C. in a second spouting bed incinerator, thereby generating a second gaseous stream comprising destructed PFAS.

Methods and systems for clean-up of hazardous spills are provided. In some aspects, there is provided a system for burning an water-oil emulsion that includes an enclosure configured to hold a water-oil emulsion; one or more conductive rods disposed throughout the enclosure, each rod of the one or more roads having a heater portion to be submerged in the water-oil emulsion and a collector portion to project above the water-oil emulsion, wherein the collector portion is longer than the heater portion; and a delivery system for supplying an water-oil emulsion to the enclosure, the delivery system is configured to maintain a constant level of the water-oil emulsion in the enclosure as the water-oil emulsion is burned. The enclosure may further include one or more adjustable air inlets.
