The Canadian edition of “Harry Potter and the Order of the Phoenix” — to be released later this month as the fifth book in J.K. Rowlings’ phenomenally popular series — has been printed on chlorine-free, 100 percent post-consumer recycled paper. With a first print run of 935,000 copies, this is by far the largest recycled printing in Canadian history. Rowlings endorsed the move with a note in the front of the Canadian edition and urged other publishers to follow the lead of Raincoast Books, her Canadian publisher. Nicole Rycroft of Markets Initiative, an environmental coalition in British Columbia, says 35 other major Canadian publishers are considering printing on recycled paper, as are publishers in Britain, Germany, and Italy. “It’s a good business decision,” Rycroft said, “they’re seeing the kind of positive publicity it can bring.” Recent books by Canadian authors Alice Munro and Margaret Atwood have also been printed on recycled stock.
