Hazardous waste

Patent Pending Hazardous waste is waste that poses substantial or potential threats to public health or the environment.[1] In the United States, the treatment, storage, and disposal of hazardous waste is regulated under the Resource Conservation and Recovery Act (RCRA). Hazardous wastes are defined under RCRA in 40 CFR 261 where they are divided into two major categories: characteristic wastes and listed wastes.
