Per our joint development agreement with the Northrop Grumman Corporation, Cirque has exclusive rights to all markets – outside of the Federal Government sector – for its DGU technology. Rising costs of energy and waste disposal, as well as environmental regulation, position a wide variety of retail, manufacture, service and municipal business enterprises to potentially benefit from the Company’s commercial DGU systems.
