Probably not. The “AS” in ASIC stands for “application-specific”, they are designed to be extremely good at just the one specific purpose that they were meant to be used for and if they’re good at anything else it’s sheer coincidence. In Bitcoin’s case that purpose is applying a particular pattern of SHA-256 hashing to a particular-sized blob of data. I doubt there are other applications for that particular sequence of steps.

ASICs likely get used in mining until they burn out, or until they’re supplanted by new designs that make them uneconomical to run in the face of competition, so they probably just get recycled.
