Collect waste in a designated collection container Use a funnel with a 'screen insert' while collecting waste to remove tissue debris from waste Add the entire contents of one Formaway bottle to each gallon of aldehyde waste Secure lid on the collection container and agitate container to thoroughly mix solutions, make sure the agitation ultimately results in complete dissolution of Formaway Formalin Neutralizer Powder Allow the mixed solution to stand for 20 to 25 minutes for the reaction to be complete If required, test treated solution for any aldehyde residual prior to disposal (follow instructions for Formaway Formaldehyde Residual Screening Test Kit) Pour treated waste into sanitary sewer and rinse container with cold tap water, preparing it for reuse
