A Trash Compactor is Going to the Space Station
Astronauts aboard the International Space Station (ISS) generate a significant amount of waste, requiring efficient and effective waste management systems to sustain long-duration missions. Recognizing this challenge, Sierra Space has secured a contract to develop an innovative Trash Compaction and Processing System (TCPS) for the ISS, set to be tested in 2026.
Why the Need for a Trash Compactor?
As humans venture further into space, particularly with missions to the Moon and Mars on the horizon, managing space waste becomes crucial. Traditional methods of dealing with trash, such as sending it back to Earth or disposing of it in the atmosphere, are no longer feasible as missions extend in duration. The TCPS aims to alleviate these concerns by:
- Reducing Waste Volume: The TCPS is designed to compact waste by up to 75%, facilitating easier storage.
- Recovering Resources: The system is capable of extracting water and other gases from waste materials for potential reclamation.
- Providing Radiation Shielding: Compacting waste into solid blocks may offer additional protection against cosmic radiation during long-duration missions.
System Overview: The TCPS
The TCPS will feature advanced technology to ensure efficient waste management in microgravity. It is a stand-alone system requiring only power, data, and air-cooling interfaces, making it relatively simple for astronauts to operate.
Components of the TCPS
| Component | Function |
|---|---|
| Waste Compactor | Compresses trash into solid tiles under heat and pressure. |
| Catalytic Oxidizer (CatOx) | Processes volatile organic compounds (VOCs) for safety. |
| Water Recovery Unit | Extracts water from wet waste for reclamation. |
| Control Interface | Facilitates operation by the astronauts. |
Importance for Future Missions
"Long-term space travel requires the efficient use of every ounce of material, where waste management becomes critical for survival and mission integrity." – Tom Vice, CEO of Sierra Space
Future missions beyond low Earth orbit necessitate innovations like the TCPS to handle waste sustainably. The research and development behind this system align with the broader objectives of humanity's presence in space and the ultimate goal of sustainable exploration.
Nasa & TCPS: Collaboration for the Future
NASA is actively involved in the development of the TCPS technology, as it reflects the agency's commitment to sustainability and efficient resource utilization in space missions. As of January 2024, Sierra Space completed the initial design phase and is moving ahead with fabricating the ground testing unit.

The Future of Space Waste Management
With successfully deployed systems like the TCPS, NASA and Sierra Space aim to usher in a new era of waste management in space, essential for planning long-duration exploration missions. The innovations developed through this contract can help sustain human life beyond Earth and encourage the exploration of Mars and beyond.
Potential Applications
- Crews on missions to the Moon or Mars can maintain efficient waste management practices.
- Reclaimed water can support life support systems and enhance resource sustainability in space habitats.
- Innovative compact waste methods can lead to new materials for radiation shielding.
