An imperative for prolonged Space flight missions is the conservation
of resources. Extensive resupply could pose technological and logistic
al challenges for those responsible for the management and successful
completion of the mission. Therefore, the biological waste water recla
mation system (BWWR) which requires little or no expendable supplies a
nd the waste cellulose to edible mushroom conversion system (CMCS) whi
ch is conceived as a low energy crop waste recycling system are protot
ype instruments which have been conceived as solutions to the mission
resupply problem. Out tests, conducted with relatively crude devices b
ased on the original concepts, indicate that further research on the b
asic principles underlying the systems and refinement of the engineeri
ng designs will lead to hardware with the potential to satisfy the req
uirement for minimal re-supply while providing recycled water and edib
le mushrooms. (C) 1998 Elsevier Science Ltd. All rights reserved.
