Can a black and white photocopy be treated in some simple way so that the paper could be reused as scratch paper (not necessarily as copy paper)? Could some treatment cause the ink to fade enough to leave a blank or nearly blank piece of paper?

From the Wikipedia article about (photocopier toner)...

http://en.wikipedia.org/wiki/Toner

Quote
Most toner goes to printed pages, a large fraction of which are ultimately recycled in paper recovery and recycling operations. Removal of toner from the pulp is not easy, and toner formulations to ease this step have been reported.  Hydrolyzable, water-soluble, and caustic-soluble toner resins have been reported, but do not appear to enjoy wide-spread application. Recovery of waste toner with other inks and resins from paper recycling plants occurs as sludge, a low-value off-product.

It would be nice though to get the toner/ink directly off the paper, without having to mash it up and re-make the paper.
But I haven't heard of process to make that happen, after all the toner/ink is supposed to stay on the paper and not to fade too much i.e. in direct sunlight.

May I suggest a generous application of white correction fluid.
