A Bioregenerative Life Support System Based on Near Term Technology Developments

Bioregenerative life support systems have the potential to reduce the need for resupply from Earth for extraterrestrial habitats. The proposed advanced life support system, developed by an international and interdisciplinary team, is an innovation combination of current and near term research and technologies. The system combines physico-chemical methods with algae, aquaculture and higher plants to purify wastes and provide consumables. A closed loop percentage of 90-95% percent is expected with additional supplies for dietary supplement and maintenance. The information gained from the development of the proposed artificial biosphere can also help to solve sustainability problems currently prevalent on Earth.
