Retail Hazardous Waste

Products that can no longer be used for their intended purpose are considered hazardous waste and must be disposed of properly.  For example, retail products that are returned, spent (light bulbs, batteries, etc.), spilled, empty (applicable pharmacy containers), damaged or leaking are considered hazardous waste.  The distinction between such products and others is to ensure that hazardous waste is separated from solid waste and are not thrown into the trash.

Universal Waste

Universal Waste is hazardous waste that is common among multiple types of operations.  Most businesses generate some form of Universal Waste.  Examples include batteries, electronic waste, fluorescent bulbs, aerosol and latex paints.  Management and disposal requirements for these types of waste are more lenient than typical hazardous waste.
