What benefit does freeze-drying provide for space station waste management?
Answer
It results in significantly less packaging and organic waste.
Space stations have very limited capacity for trash, and jettisoning waste into orbit is restricted. Furthermore, returning waste to Earth is rarely an option due to logistics. Because freeze-dried foods are condensed and compact, they require less packaging than canned or fresh alternatives. Additionally, by removing the water weight, there is less organic waste to manage after consumption. This reduction in volume and weight helps manage the limited disposal capacity of the station.
