Wastestream Identification Chart

Categorizing wastes can be a difficult task. This chart is intended to help you identify what wastes fall under which categories. It provides information on types of wastes commonly produced by veterinary facilities and sorts them into various regulatory categories. The chart also lists common examples of each waste category and shows the typical waste disposal methods employed.

Please note that this chart is based on federal waste definitions. State regulations may define wastes differently and therefore may affect disposal options.
