All greens in the kitchen - together, or not?

What is an ideal arrangement for the vegetables and fruit on the counter.
Just this morning (when I found the mouldy orange of my other question), I arranged the older and fresher vegs and fruit on a small wooden table, divided in baskets.
I remembered having seen on the net a recent design of racks that enhances the longevity of vegetables, using specific combinations of proximity and with an addition of sand (...?...) to one or two things.
I believe there is a way.. several ways to keep greens fresher for longer lengths of time in the kitchen.

Therefore: What should go next to what; and what shouldn’t?

P.S.
Does anyone know what design I’m talking about? I think it’s by a Korean designer.

Cheers!
