RCRA was enacted in 1976 to address the growing problem of hazardous waste disposal. The law aims to protect human health and the environment by regulating the generation, transportation, treatment, storage, and disposal of hazardous waste.

Toxicity is not a characteristic of hazardous waste under RCRA. The four characteristics of hazardous waste under RCRA are ignitability, corrosivity, reactivity, and toxicity.

Waste characterization is the process of identifying and classifying hazardous waste. It involves conducting a series of tests and analyses to determine the physical and chemical properties of the waste, as well as its potential hazards to human health and the environment.

Material Safety Data Sheets (MSDSs) are not used to characterize hazardous waste. MSDSs provide information on the hazards of a chemical product, but they do not provide the data necessary to classify a waste as hazardous.

A hazardous waste manifest is used to track the movement of hazardous waste from its generation to its final disposal. It provides information on the generator, transporter, and destination of the waste, as well as the type and quantity of the waste.

Waste minimization is the process of reducing the amount of hazardous waste generated. It involves a variety of techniques, such as process changes, equipment modifications, and recycling.

Waste minimization does not increase the amount of hazardous waste generated. It reduces the amount of hazardous waste generated by reducing the amount of waste produced and by recycling and reusing materials.

Waste treatment is the process of treating hazardous waste to make it less hazardous. It involves a variety of techniques, such as chemical treatment, physical treatment, and biological treatment.

Landfilling is not a method of waste treatment. Landfilling is the process of disposing of waste by burying it in the ground. It does not treat the waste to make it less hazardous.

Waste storage is the process of storing hazardous waste before it is treated or disposed of. It involves storing the waste in a safe and secure manner to prevent leaks or spills.

Landfills are not used for the storage of hazardous waste. Hazardous waste must be stored in a secure container, in a well-ventilated area, and away from incompatible materials.

Waste disposal is the process of disposing of hazardous waste. It involves a variety of techniques, such as incineration, landfilling, and recycling.

Composting is not a method of waste disposal. Composting is the process of converting organic waste into a nutrient-rich soil amendment. It is not used to dispose of hazardous waste.

Waste management is the process of regulating the generation, transportation, treatment, storage, and disposal of hazardous waste. It involves a variety of activities, such as waste characterization, waste minimization, waste treatment, and waste disposal.

Waste management does not aim to increase the amount of waste generated. It aims to reduce the amount of waste generated and to promote the recycling and reuse of waste.
