In March 2004 Katahdin Paper Co.'s uncoated groundwood paper mill in East Millinocket,Maine,became the first ongoing true-neutral deinking facility in the world using old newspapers (ONP) and old magazine grade (OMG) recovered paper furnishes.During the past year and a half of operations with the new true-neutral process,implemented in cooperation with its developer Kemira Chemicals Inc.,the mill has significantly reduced pulping and bleaching costs by completely eliminating the usage of several chemicals,while maintaining pulp quality,yield,and production.Switching to true-neutral has also improved deinking process stability compared with the alkaline process previously used at East Millinocket.
