| Who is the PEWG?
The Propulsion Environmental Working Group (PEWG) is a group of industry and government leaders striving to insert clean, safe, and cost effective sustainment technology improvements in the propulsion community. The focus of the PEWG is to bring about changes in Government and Industry to address issues in Environmental Security with the goal of "The Ultimate Green Engine."
What is the Ultimate Green Engine?
The Ultimate "Green Engine" should be designed and built in such a way that the parts do not corrode or wear-out during the period the engine is used, its economic design life. There should be no toxic materials and/or components delivered with the engine. Subsequently, no HAZMATs are used and/or released during manufacturing, maintaining, or reworking the engine. Engine operation should have minimal environmental impacts from noise, and air emissions. Finally, the valuable components and/or materials are recovered when the use period ends.
