The proper thing to do would ship them to a paper recycling company.I mean, suppose a publishing company has a big goof up and accidentally prints a million extra copies of the latest Harlequin romance of the month book. Are you guys really going to be morally outraged ( at the idea of burning books... ignore environmental reasons here please) if they realize the most economical thing to do is ship off the extras to an incinerator and perform a mass burning?
