What sort of system do they use on a space station? I've seen sketches - it's small (has to be!) and does some recycling, though I don't know how much. But if you're not using it in a space station, why are you disposing of the solids? You should be using them as fertiliser to displace use of oil-based 'fertilisers'!

As far as I'm concerned the reason is that LinkedIn has several discussion groups related to biomimetics/biomimicry and these have taken over. I suggest that if you want to contribute to or observe some lively discussions, you should join LinkedIn and join the relevant groups. > > Julian Vincent >
