Impact/Purpose:
Bacillus anthracis (B. anthracis) spores were released through the U.S. mail system in 2001, highlighting the need to develop efficacious methods of decontaminating and disposing of materials contaminated with biological agents. Incineration of building decontamination residue is a disposal option for such material, although the complete inactivation of bacterial spores via this technique is not a certainty. Tests revealed that under some circumstances, Geobacillus stearothermophilus (G. stearothermophilus; a surrogate for B. anthracis) spores embedded in building materials remained active after 35 min in a pilot-scale incinerator and survived with internal material bundle temperatures reaching over 500 °C. The results of the pilot-scale incinerator experiments are compared to model predictions to assess the accuracy of the model.
