Complete closure is probably impossible. The best pressure vessels still leak, and airlock ops lose mass. There will also need to maintain rotation in the face of various losses created by rotating the atmosphere. And, last but not least, it will be very difficult to recycle EVERYTHING. Heres an exercise: as you go about your day notice all the things you use and try to image recycling them.
