Specimens preserved in Carolina’s Perfect Solution can, in most cases, be disposed of in a school’s regular waste destined for a landfill or incinerator. The specimens are not classifiable as federal hazardous waste and do not represent a biohazard. However, you should check with your local solid waste authority (local governmental authority in charge of solid waste, local landfill, or waste disposal company if applicable) to ensure that this is an acceptable practice. If it is, we recommend that you double bag the specimens before placing them in your school’s regular waste.
