TIAX has developed a technology to meet EPA and homeland security needs for bio-agent decontamination in railway cars and other situations. It provides simultaneous encapsulation and killing of biological contaminants with the added capability for decontamination of chemical and radiological hazards. Current technologies are labor-intensive involving separate steps for site preparation, decontamination, wash-down, and waste disposal. TIAX’s technology combines tasks, reduces labor, and requires a smaller logistical response. The remediation process provides protection against worker exposure and environmental cross-contamination; and reduces hazardous waste disposal volumes versus typical liquid wash-down. TIAX’s past research shows essentially complete removal of hazards with a demonstrated 7-log kill of Bacillus atrophaeus. The technology may be used in response to hazardous material releases in buildings and transportation systems, including trains, buses and aircraft. According to an independent technology commercialization assessment, the technology is transferable to the Environmental Services Market (e.g., mold remediation and asbestos abatement) with a reported 2013 market approaching of $2.1B and the hazardous waste market of $25.9B in 2014. End users include hazmat companies for commercial remediation response and homeowners for smaller clean-up projects at hardware retailers. TIAX has received interest from manufacturers in adding this technology to their existing product lines.
