Our diapers are marked using TCF (Totally Chlorine Free) pulp which means that the bleaching process does not use chlorine or chlorine derivatives. It is a much safer process because it uses oxygen, peroxide, or ozone-based bleaching systems. These methods are safer than using chlorine because they do not generate dioxins. This is the safest bleaching method you'll find being used in diapers at this time.
Diapers that are marked using ECF (Elemental Chlorine Free) pulp means that elemental chlorine is not used. However, the pulp is bleached with chlorine dioxide, which is a chlorine derivative and itself is a hazardous substance. This process reduces dioxins, but it is believed that it doesn't fully eliminate them.
