Description:
During this SBIR Phase I effort, TDA Research, Inc. (TDA) evaluated commercially available sprayable and pour polyurethane foams (including building insulation foams) to encapsulate contaminated materials, for example, materials contaminated by a chemical or biological attack or a disease outbreak. The project objective was to determine whether the encapsulated materials could then be transported and disposed of with greater safety to personnel and with simplified regulatory requirements, thus greatly reducing the time and cost of remediation. The effectiveness of this approach was measured by demonstrating performance that lowers the threat, and therefore the category that describes the waste. Tests demonstrated that the foam forms a continuous, mechanically robust barrier over irregular objects that can contain the vapor of a volatile liquid contaminant and prevent the leaching of a water-soluble contaminant.
