Problem: The Air Force Research Laboratory (AFRL) uses parts fabricated from gallium arsenide for radar and communication systems. With the increasingly stringent waste disposal requirements, device and system, as well as production costs, could skyrocket. AFRL Materials and Manufacturing Directorate (ML) was interested in developing new methods for arsenic waste reduction to assure the continued availability of affordable parts for their military systems.
Solution: The University of Dayton Research Institute (UDRI) developed a system to detoxify gallium arsenide wastes. The UDRI system can separate the waste chemicals into their constituents that can be reused rather than discarded. However, the UDRI system needed to be tailored to be more convenient to the user. UDRI also needed larger samples of gallium arsenide wastes to verify performance of the chemicals in the system. Through this Cooperative Research and Development Agreement (CRADA), AFRL is able to supply needed industry contacts, as well as larger samples of gallium arsenide. AFRL also advises on the appropriateness of conceptual processes and identifies industrial systems where the proposed processes may have an impact.
