Preliminary tests have been performed to characterize the behavior of composite wastes that are representative of the types of wastes produced on current and previous space missions such as International Space Station, Space Shuttle, MIR and Skylab. ...Preliminary tests were conducted to characterize the volume reduction, bonding, encapsulation and plastic extrusion of the waste composite. The preliminary tests are designed to provide the data needed to design the first prototype Plastic Melt Waste Compactor.

This paper describes the results of tests conducted using the PMWC with a wet and dry waste composite that was representative of the waste types expected to be encountered on long duration human space exploration missions.

The current paper will present results on pyrolysis of various mixtures of plastic (polyethylene), food (composite of 40% assorted dried food, 30% flour, 10% milk powder, 7% egg powder, 4% potato powder, 3% gluten, 3% corn starch, 3% sugar), and paper (cellulose).
