摘要：
A non-solvent chemical approach has been developed to pulper de-ink old newsprint (ONP) and some magazine grades. A washing step is required, but the de-inking takes place at operating process temperatures and pH conditions. This eliminates disadvantages presented by conventional treatments. The treatment is applicable to secondary fibre mills as replacement for higher grade fibre or for partial replacement of virgin fibre in newsprint.
