Elemental chlorine-free (ECF)

ECF indicates paper made from either virgin or recycled fiber that is bleached using alternative chlorine compounds (such as chlorine dioxide) as a substitute for elemental chlorine. ECF bleaching reduces harmful byproducts, relative to elemental chlorine bleaching. The ECF process has been recognized by both the European Commission and the United States Environmental Protection Agency as “Best Available Technology.” According to the Alliance for Environmental Technology, more than 85 percentage of the world’s bleached chemical pulp makes use of ECF bleaching technologies.
