I wish I could remember the name of the book but the general idea was about a company that "mined" the debris field and had an in orbit titanium recycling facility. Collection of small debris was done with massive spider silk sheets. The collector would closely match the direction and velocity of the debris field and scoop it up. The collected debris was then milled and cold welded to create new components.
All fiction of course, but I love the idea.
