Capitol Technology University’s TRAPSAT - recently merged into their CACTUS-1 dual-mission cubesat - will actually trap space debris for study rather than simply burning it up on re-entry.
The preliminary testing (done by high altitude balloon release I think?) has already attracted some attention simply by accidentally capturing high-altitude dust particles that surprised atmospheric scientists.
These trapsat pages are old, but the project is still alive and kicking.
