Many plastics used in construction tend to have much longer lifespans (years to decades) so their recycleability, whilst it shouldn't be dismissed, is a less immediate concern. E.g., I'm adding PVC cable and pipe ducting in various areas of my house, and am using polycarbonate discs as spacers for shelf uprights on an uneven wall. Both will stay in situ at least until I move (which I have no plans to do at present).
