Abstract

A solid particulate urea formaldehyde foam is used to treat biological waste materials commonly stored indoors with a slow continual release of formaldehyde in an amount that is toxic to microorganisms but does not cause harm to humans. Liquids are absorbed into the foam creating a solid disposable mass which may be disposable in a landfill. Waste odors are overcome.
