Direct Mail — With a Conscience

The Elemental Chlorine Free (ECF) bleaching process uses chlorine dioxide rather than chlorine gas, reducing the amount of harmful dioxins that exit from the paper mill. Of the three types of bleaching methods, ECF is the most common.

Processed Chlorine Free (PCF) refers to papers that have been recycled and processed without the use of chlorine. The PCF bleaching process is more environmentally friendly than ECF.
