It's a bit dated now, but the RIPE report, ASN MIA, sounds like what

When I look at this more recently, the conclusion still seems to be
valid: we'll run out of 16 bit ASN's somewhere in 2011 to 2013. There
are a lot of unused ASN's out there. Recovering them will postpone the
problem by a few years but it won't solve it. The basic problem with
recovery is how to decide if an ASN is really no longer used/needed.
There is (still) no mechanism to do this.

Why not go after low lying fruit first? If an ASN was assigned years ago
and hasn't appeared in the RIB for the past year that ASN should be
reclaimed. Send warning emails to the registered contacts as well as to
the assigning LIR and after 3 months - just reclaim it.
