From the MTV interview:
Cleaning Supplies: "At [an early] point in the movie, [the Wolf] takes a gun off of a dead Predator, and so he has double shoulder cannons," Colin explained. "There's also a cleaner case where he stores all his new weapons. It has an implosion bomb that he uses for imploding the crashed ship to basically get rid of it. ... That's a new type of bomb he has."
Watch the trailer again. When you see the Predator running away from the ship, you see it collapsing into itself, hence implosion. He implodes the ship. It does not blow up.
