Literally, cannibalistic. «Cannibalize» might mean to take mechanical parts from a device in order to repair others, the way that «scavenge» describes the use of backpressure to reclaim unspent fuel in a four-stroke internal combustion motor. Anthropophagous, anthropophagy, anthropophaginian, anthropophagite, and anthropophagi all seem only used to describe humans eating the flesh of other humans.

Found in Harp­er Lee’s *Go Set a Watch­man*. I don’t want to go in to the con­text here, but I was almost sor­ry I looked this one up.
