Earlier last year I posted an idea for an alternative to a septic using plants in an enclosed box to biodegrade waste product.
I knew then that Earthship had something very similar and, in hindsight, I should have posted a link to the Earthship page outlining their "Exterior Botanical Cell" here:

That said, why isn't this idea more applied and developed?
It's basically a biosphere for waste management. The waste products in entirely controlled and contained with no contact with the surrounding environment through the whole process. It would seem to me the principle could be applied in varying degrees and scales to fit anyone's needs minus the emptying buckets.
I realize the bucket method is very efficient and inexpensive and what not, but, if one has the means, wouldn't a system that eliminates the bucket system be the ideal? (Also, the bucket system, in which the waste product is put in a
compost pile is not exactly sealed off from the surrounding environment, btw.)
