Orbital debris has long been of concern and several methods of dealing
with it have been proposed in recent years.
Larger objects can, for the most part, be avoided as they are tracked.
Some of them are spacecraft that reached the end of their operational
lives and could still be useful if they could be refurbished. That
could be a possible source of revenue for a salvage firm, provided
that those inactive spacecraft could be made safe prior to being
brought back. (One space shuttle mission showed this was possible.)
Others could be removed from orbit if they were put into, say, a
trajectory which would eventually cause them to re-enter and burn up.
Tasks like that could be something that a successor to the ATV might
be suited for. Perhaps such a spacecraft could be developed by a
private company with backing from a government space agency.
Smaller pieces, such as paint chips, won't be so easy to remove. I
remember reading of one proposal that deployed a fine-mesh net which
would catch them. Maybe an ATV successor might not be the best
spacecraft for that as precise maneuvering probably wouldn't be
