Recycling Chemical Waste

For example, distillation bottoms from one process used as feedstock in another process constitutes the use or reuse of a material. Another example would be the use of a substance as a workable substitute for a commercial product (e.g., spent pickle liquor used as a sludge conditioner in wastewater treatment). "Use comprising disposal" refers to recycling that requires the direct application of wastes or products containing wastes to the soil, such as asphalt that contains waste from petroleum refining. A hazardous waste is burned for its value as fuel in a recycling process known as "burning for energy recovery" (either directly or when it is used to produce a fuel).
