ELEMENTAL CHLORINE-FREE (ECF)

Pulp produced without using elemental chlorine for bleaching. This method significantly reduces the amount of harmful waste produced by the pulp bleaching process and prevents carcinogenic byproducts.

All French papers are produced ECF.

RECYCLED FIBER

Pulp fiber derived from recovered materials, other than mill broke, and incorporated in the fiber mix of a finished product.

POSTCONSUMER RECYCLED WASTER FIBER (PCW)

Pulp fiber that has been used by consumers (schools, offices, stores, residences) and subsequently diverted from the solid waste stream for re-use.

PRECONSUMER RECYCLED FIBER

Pulp fiber that has not met its intended end-use by a consumer and is collected for re-use in manufacturing. Preconsumer materials in papermaking include envelope clippings and trimming from the printing process. Preconsumer recycled fiber does not include mill broke.
