Couldn't you have something which is a hollow tube, with a thread inside. You then have sufficiently strong disks with turning handles both on top and underneath, and a little screw out airhole with a threaded plug.. You then screw one of these into the tube, right down to the end to make a bottom, and start putting food scraps in. After you've put enough food in, you screw in another disk with the airhole unplugged. Once you've screwed it down enough, so that the food scraps are being compressed, you then screw in the air plug, sealing that section. You then add food scraps on top of that disk. The disks should be tight enough to seal in the food and smells. Once you've put in enough, you screw down a new disk in the same way. You continue adding food scraps and disks until the unit is full. You then put in the last disk on top, and turn it over, and screw out the very first disk. This reveals your oldest compost, which you can remove. Perhaps you'd remove one or two disks, then continue putting food scraps in what used to be the bottom, but is now the top. Once that's full up again, you flip it over, and take out the two oldest sections. I'm now assuming space for four sections in total. The item would have to be invertible, and have a removable lid for the open end which could fit on either end. Perhaps an external screw thread, and the lid would pop open and shut. Perhaps there would be a screw on (same thread) base as well. So you can invert the unit by unscrewing the lid and base, and screwing them on the other ends.
It would take more research to see what would happen to the sealed food, i.e. would gas be produced resulting in an explosion risk? But otherwise, this could be used for composting in a small flat. Perhaps there could be open and closeable air vents on the side so that it could be put outside with the vent open to compost further.
