Hazardous waste disposal refers to the process of safely managing and disposing of waste materials that pose a risk to human health or the environment. These materials can include chemicals, batteries, medical waste, and certain types of industrial byproducts. Proper disposal methods are essential to prevent contamination of soil, water, and air. To ensure safe disposal, hazardous waste is often treated, recycled, or incinerated at specialized facilities. Regulations, such as those set by the Environmental Protection Agency (EPA), guide the handling and disposal of these materials to minimize their impact on public health and the ecosystem.
