“…This sketches opportunities for circular processing in space of inevitable fractions of crops. A report on phosphorus nutrient recovery has informed chemical processing opportunities for reuse of inedible crop fractions . Liquid formulations are ideal for encapsulating or dispersing hydrophobic substances, e.g., as nanoemulsions, and are therefore good hosts, e.g., for vitamin E or vitamin K. Hydrophilic micronutrients, e.g., vitamin B, can also be added to fortified food emulsions, such as energy drinks.…”

Future long-term human exploration of space will need a supply of resources for astronauts, including fresh food from space farms. This means it is necessary to identify combinations of crops that can be successfully grown together and which provide a balanced and palatable diet for astronauts. We used numerical optimization to identify such combinations, using macro-and micronutritional content as constraints, while optimizing water load needed for crop farming. The food constraints considered were based on the recommendations of the National Aeronautics and Space Administration (NASA), considering up to 36 nutrients and 102 crops. We evaluated 10 scenarios ("space dishes") for daily full-nutrient supply to one astronaut, with four scenarios being vegetarian (crops only) and six being omnivorous (crops and meat). Each scenario was analyzed for the capability of plant growth, including the required planting area and crop growth time and productivity; from the viewpoint of optimizing performance in space. As plants contain both edible and inedible parts and require fertilizer input, respective circularity assessments were made determining the waste generation, degree of recyclability, and overall mass processed, using three common metrics of the circular economy. The space dish identified as optimal was prepared as a salad, to allow judgment on the palatability, i.e., the "space food acceptance," by a small psychology test. These assessments are essential steps toward feasibility in long-term human space missions, for example, to Mars.

This research explores the potential of electric field enforcement in dielectric barrier discharge using specially designed pyramid‐shaped μ‐electrodes for a plasma‐assisted nitrogen fixation process. The obtained results are compared under varying conditions, including the presence and absence of titanium dioxide ( ), different oxygen concentrations in the nitrogen‐feeding gas, and residence time. The results demonstrate that the μ‐electrodes lead to an enhancement of nitrogen oxidation, which is further intensified by . The introduction of 60–70 % oxygen with nitrogen achieves the highest level of production. The synergistic effect of plasma and the catalytic effect of increase the rate of production by 20 %, resulting in a 23 % increase in energy yield. The introduction of leads to a sharp increase in production even at lower oxygen concentrations. The crucial role played by ultraviolet light‐induced electron‐hole pairs in is highlighted to promote nitrogen oxidation. Nevertheless, it is crucial to emphasize that prolonged residence times may cause the photocatalytic effect to generate alternative byproducts rather than , consequence of excessive oxidation that could prove counterproductive. These findings emphasize the potential of plasma‐assisted nitrogen fixation technology in reducing energy costs and meeting the growing demand for sustainable nitrogen‐based fertilizers.

“…In terms of finding more, we can look beyond the stars and find new places rich in P, such as lunar soil, which is rich in KREEP (K – potassium, REE – rare earth elements, and P – phosphorus), or can use recycling technology to recover P from biowaste, such as from roots. 7 The idea of using less includes using a P fertiliser that releases nutrient slowly or in a controlled manner. Solid P fertilisers, such as hydroxyapatite (HAp), where P is locked in a solid form and thus less soluble, have also attracted great attention recently, as they are advantageous in countering run-off or eutrophication.…”

Circular bioprocess for phosphorus nutrient recovery to grow lettuce in lunar space

Abstract: A looming global scarcity of the nutrient phosphorus (P) requires solutions to prevent losses via recycling and recovery. One approach is to address this practically in lunar space. Here we...
