Technology Evaluation

Supported the Alternate Technologies and Non-Stockpile Chemical Materiel Programs by evaluating technologies and processing solutions in a variety of areas including: munitions accessing, chemical agent destruction, energetics destruction, hydrolysate treatment, waste processing and agent decontamination. This included new technologies as well as improvements to existing technologies.

Over 100 technologies were identified and evaluated for chemical demilitarization applicability. The technologies were biological, chemical, electrochemical, thermal, mechanical, physical and radiological for assessing, accessing, destroying, monitoring, containing, decontamination and personnel protection. Total solutions and partial solutions were also evaluated.

Each technology was evaluated using a standard set of criteria that addressed process efficacy, process safety, environmental impacts, schedule and cost. Based on the criteria evaluations, a report was written that included conclusions and a path forward recommendation to the Government. All the Technology Evaluations were placed on a database for Government use. Eventually the Technology Evaluations were migrated to separate public and Army websites.
