• Logistics, Reduction and Repurposing (LRR) Project 
Overview 
• TtSG overview 
2 
• Summary 
- Logistics Reduction and Repurposing (LRR) will utilize a cradle-to-grave 
approach to logistics to reduce total mission logistical up mass. 
- LRR will demonstrate efficient methods to repurpose hardware originally 
designed for other uses, reduce packaging volume, and using common 
system elements for multiple mission applications. 
• Minimize intrinsic logistics mass. 
• Direct logistics component repurposing for on-orbit outfitting. 
• Compact and process logistics to useful components and products. 
• Enable long term stable storage and disposal 
• Enable logistics sharing between vehicles in different mission phases 
• Goals: new capabilities and exploration affordability 
- Reuse and repurposing. will reduce initial up mass and volume because it will 
reduce the number of dedicated crew outfitting items. 
- Compacted/processed logistical material available for radiation shielding, 
water, or propellant. 
- Enable more hygienic crew environments through waste stabilization. 
- Increase habitable volume over mission duration through compaction. 
- Reduced mass will reduce vehicle cost.

TtSG Overview 
• What is it? 
- A series of space technology alternatives for converting trash and other 
waste materials from human spaceflight into high-value products that might 
include propellants, power system fuels or oxygen and water for life support. 
• Products: This activity investigates promising lower TRL technologies 
that process waste (trash & human waste) all the way to gases which 
can be reused, thus saving launch mass. 
• Methane, hydrogen and oxygen are all candidates for use in propulsion. 
Hydrogen and oxygen can also be reused for ECLSS. 
• Systems Engineering Analysis task will guide the testing and selection of 
these technologies, which will come primarily from SBIR and other past 
work.

• Why TtSG? 
Reduce volume of trash -Current 
human spaceflight missions either 
carry trash during the entire round-trip 
mission or discard trash inside a 
logistic module which is de-orbited into 
Earth's atmosphere for destruction. 
Produce something useful from a 
waste product 
• Challenges 
Miniaturization 
Operation with minimal human 
interaction 
Do not produce hazards 
Gas cleaning and purification 
KSC-OlPP-0726: Workers in the Space Station Processing 
Facility are removing contents from the Multi-Purpose 
Logistics Module (MPLM) Leonardo to begin removing the 
contents after STS-102. The MPLM brought back nearly a 
ton of trash and excess equipment from the Space Station. 6

TtSG· Overview· 
• Terrestrial waste conversion technologies are currently moving towards 
smaller systems that operate at the generation source of waste 
• TtSG ideally will accept all types of organic wastes, including microbial 
contaminated waste, without sorting
