Abstract Space agencies are developing Bioregenerative Life Support Systems (BLSS) in
view of upcoming long-term crewed space missions. Most of these BLSS plan to include …

The increasing global population, over the last few decades, brought about the rise in
synthetic fertiliser market prices along with explosive agricultural demand. Source …

In recent years, source-separated urine has garnered widespread recognition as a valuable
nutrient recovery resource. This paper summarizes urine components globally and related …

Bioreactors for space habitation systems have unique constraints. One type of reactor that
could meet these constraints are membrane aerated biological reactors (MABRs). The …

The pilot-scale partial nitrification-anaerobic ammonia oxidation (PN-Anammox) process for
landfill leachate treatment has been running stably for 2 years. The degradation …

Plant cultivation is a key aspect of future long-distance space missions, and the creation of
an efficient food system will not be possible without it. The production of fertilizer in space is …

The application of hydroponic cultivation fertilized with biologically nitrified synthetic urine
can produce nitrate-rich fertilizer for lettuce (Lactuca sativa var. capitata L.). The mounting …

Human urine is considered a major stream of nitrogen mass flow in domestic wastewater,
which is widely available and rich in valuable nutrient resources for hydroponic cultivation …

Partial nitrification (PN) has been successfully applied in treating wastewater with medium or
low concentrations of ammonia, whereas the treatment of high-concentration ammonia …

Poultry processing wastewater (PPW) is a nutrient-rich effluent with the potential for reuse in
crop irrigation. This study investigated transforming PPW into a hydroponic nutrient solution …
