Circular Economy Pathways for Airport Climate Change Mitigation

Business Strategy and the Environment, EarlyView.
ABSTRACT Airport operators face growing climate‐change pressures; the circular economy offers pathways to reduce impacts and recover resources. We examine how airport operators apply the circular economy in practice. We use an exploratory qualitative multicase design based on practitioner‐generated documents (e.g., press releases and sustainability ...

A structural design comparison of metallic and composite aircraft pressure retaining doors [PDF]

, 2012
The pressure retaining door is obviously a sensible part of an aircraft, and the design criteria is much more critical than for the fuselage, so a problem caused by this critical criteria is the heavy weight of the door structure because it should be ...
