- We dissect specimens containing formaldehyde in our high school biology classes. We were wondering if there are certain disposal rules/laws in place for formaldehyde containing specimens?
Based on DES research, some formaldehyde solutions may exhibit the hazardous waste characteristics of ignitability and corrosivity; however, it is unlikely that specimens originally placed in formaldehyde and then transferred to a container containing propylene glycol will be found to exhibit a characteristic of hazardous waste. To determine if the specimens exhibit such characteristics, you will need to have the specimen tested . If the testing reveals that the specimens do not display the hazardous characteristics, you can treat is as a solid waste. You will want to contact your solid waste transporter, to ensure that they will accept the waste. If your transporter does not accept the waste, or testing reveals your waste is hazardous, you can contact DES for a list of hazardous transporters that will accept your waste, or call Special Investigations at (603) 271-3899.
