NASA’s LunaRecycle Challenge is seeking practical ways to turn solid waste from future lunar missions into useful materials. Launched in September 2024, the NASA Centennial Challenge offers up to $3 million across two phases—not a single $3 million prize—to teams developing physical recycling systems and digital models.
The competition focuses on non-biological waste such as packaging, plastic films, foam, fabrics, clothing, metals and construction-related materials. As of August 16, 2026, NASA listed 16 Phase 2 finalists from 11 U.S. states, with final prototype demonstrations and judging scheduled for August 2026. The supplied official status information does not confirm a final winner.
Why lunar waste is an engineering problem
On Earth, waste can be transported to recycling facilities, landfills or incinerators. A lunar habitat will have none of those options at comparable scale. Storage volume, electricity, equipment mass, maintenance and astronaut labor will all be limited.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
NASA estimates that a four-person crew could generate more than 2,100 kilograms (about 4,600 pounds) of single-use waste over 365 days. That is a modeled scenario, not a guaranteed Artemis figure. The estimate includes material such as food packaging, plastic films, foam packaging and clothing.
#1 Best Overall
Every kilogram launched or resupplied carries a transportation cost. Simply storing waste also consumes valuable habitat space. But recycling equipment creates its own burden: it adds mass, uses power, requires maintenance and may need sorting, cleaning or replacement parts. The central question is therefore not just whether a process can recycle material, but whether the recovered output is worth the resources needed to produce it.
What LunaRecycle is—and is not
LunaRecycle is a NASA Centennial Challenge administered through NASA’s Prizes, Challenges and Crowdsourcing Program, with the University of Alabama serving as NASA’s partner organization for administration.
Its target is solid, non-gaseous, non-biological and non-metabolic waste from longer-duration lunar operations. That can include:
- Food and other packaging
- Plastic films and foam
- Fabrics and discarded clothing
- Metals
- Operational and manufacturing waste
- Materials associated with habitat construction
It is not primarily a contest to remove Apollo hardware or orbital debris, and it is not a human biological-waste or “space toilet” competition. Those are separate problems.

What NASA wants teams to produce
NASA is looking beyond simple compaction. The desired systems should convert waste into useful feedstocks, multi-use materials, products or resources for exploration, manufacturing, science or habitat operations.
“Recycling” can cover several approaches, including direct reuse, mechanical processing, remanufacturing, material recovery or conversion into a different product. A system that only reduces trash volume may be useful, but a system that produces a reliable 3D-printing feedstock, repair material, tool, fixture, packaging component or structural product offers a clearer operational benefit.
The two technical tracks
Prototype Build
Teams in the Prototype Build track develop a physical recycling solution. Phase 1 required detailed designs, but hardware was not required for that submission. Phase 2 moved toward physical prototypes and demonstrations.

The Digital Twin track uses digital models and visualizations to represent how a recycling system operates and what it produces. A credible model can help examine throughput, material flows, energy demand, mass, integration and operating scenarios before a system is considered for a lunar environment.
A digital twin cannot fully demonstrate dust behavior, contamination, mechanical wear, thermal control or operator interaction. It complements physical testing rather than replacing it.
How the $3 million prize purse is divided
| Stage | Purpose | Maximum allocation |
|---|---|---|
| Phase 1 | Early prototype-build designs and preliminary digital twins | Up to $1 million |
| Phase 2 | Milestone development, physical prototypes, demonstrations and final judging | Up to $2 million |
| Total competition | All phases, tracks and awards | Up to $3 million |
The phrase “up to” matters. The $3 million is the maximum total purse distributed across phases and awards, not a guaranteed single payment to one team.
Timeline and current status

- February 2026: Phase 2 finalists were expected to be announced.
- August 2026: Final prototype demonstrations and judging were scheduled.
NASA reported that more than 1,200 people or teams registered for Phase 1 and nearly 200 submissions were evaluated. The agency announced 17 Phase 1 winning teams from five countries and nine U.S. states.

Phase 1 allowed international participation, while Phase 2 was limited to eligible U.S. individuals and teams, with eligibility tied to U.S. citizenship. Participants did not necessarily need to have entered Phase 1 to compete in Phase 2.
Rank #4
Because the relevant status snapshot is August 16, 2026, it is more accurate to describe LunaRecycle as being in or around its final judging period than to name a winner. A finalist or winner should not automatically be described as a NASA contractor, Artemis supplier or provider of flight-ready hardware.

Mixed and contaminated waste
Real waste is rarely a clean, uniform feedstock. Food residue, adhesives, coatings, fibers, composites and different plastics can reduce output quality or damage machinery. Teams must show whether their systems need extensive pre-sorting and who performs that work.
Energy and mass
Shredding, melting, heating, extrusion, separation and chemical processing can consume substantial power. A complex system may recover more material but be less attractive if its launch mass, energy demand or maintenance burden is too high. A simpler modular system may be more useful if it is robust and repairable.
Crew time
Astronaut labor is scarce. Frequent sorting, cleaning, calibration, jam removal or manual loading can make an otherwise effective machine impractical. The system must be designed around realistic crew schedules rather than laboratory convenience.
Best Value
Safety and containment
NASA has emphasized low hazards and safe operation. Relevant risks include toxic emissions, fire, volatile chemicals, dust, sharp fragments, high temperatures, pressure vessels and exposure to residues during maintenance. A strong design should explain how failures are contained and how the crew safely services the equipment.
Reliability and repair
A laboratory demonstration is not the same as years of operation in a lunar habitat. Important questions include whether wear parts are replaceable, whether the machine tolerates imperfect feedstock, what happens after a power interruption or jam, and whether it depends on consumables that must be shipped from Earth.
Useful output quality
“Turning trash into resources” is too vague without defining the resulting material’s properties and use. A proposal should specify whether its output can become a manufacturing feedstock, repair component, protective item, packaging material, tool or fixture—and how consistently it can meet those requirements.

The strongest LunaRecycle concept may not have the highest theoretical recovery rate. It will need to balance recovery against mass, energy, crew time, safety, reliability and output quality. It must also fit into the broader habitat workflow: collection, sorting, processing, storage, manufacturing and maintenance.
NASA has suggested that the research could inspire terrestrial recycling approaches, including smaller systems, reduced toxic outputs or improved efficiency. Those are potential spillover benefits, not proof that a lunar system will automatically be commercially competitive on Earth.
More broadly, LunaRecycle recognizes that sustainable lunar exploration requires more than extracting resources from the Moon. It also requires managing the materials humans bring with them. If future crews can convert discarded packaging, clothing, plastics and metals into useful manufacturing inputs without spending more mass, power and labor than the result is worth, waste becomes part of the lunar logistics solution rather than just another burden.
