Collection, compaction and storage of solid waste for space missions

Area of Science:

• Space exploration
• Waste management systems
• Engineering

Background:

• Crew-generated trash volume increases significantly during extended manned space flights.
• Limited storage volume in spacecraft necessitates efficient trash management solutions.
• Effective trash management is critical for mission success and crew well-being.

Purpose of the Study:

• To address key considerations in space trash management for manned missions.
• To discuss design approaches for trash collection, compaction, and storage.
• To present the trash compactor design developed for the Space Station Freedom program.

Main Methods:

• Defining trash models, including generation rates and physical/chemical characteristics.
• Evaluating methods for trash collection, temporary stowage, and processing.
• Analyzing treatment methods for biochemical stabilization and volume reduction.
• Investigating storage solutions for processed trash.

Main Results:

• Focus on practical design approaches for trash collection, compaction, and storage.
• Details on a specific trash compactor design for Space Station Freedom.
• Identified critical factors for effective in-space waste management.

Conclusions:

• Efficient trash collection and volume reduction are vital for long-duration space missions.
• A comprehensive approach to trash management, from collection to storage, is required.
• The developed trash compactor design aims to address critical volume reduction needs for future space habitats.
