Objectif The Selserec process was developed to selectively separate the components of a laboratory produced wash water effluent stream into a filler rich fraction, a fibre rich fraction and a cellulosic fines rich fraction. Pilot scale trials achieved fibre and filler selectivity, but not cellulosic fines selectivity. Optimisation of the process is necessary to achieve all objectives on a large scale. In addition: Methodologies were developed for the ink release and ink redeposition testing, allowing chemicals to be identified to improve the deinking process - joint ownership SCA and Allied Colloids. Chemicals were identified which enhanced the standard deinking chemistry to achieve improved deinked fibre brightness - joint ownership SCA and Allied Colloids. A novel laboratory microflotation device was constructed, evaluated and used in project.Today's processing of returned paper into raw material for new paper production normally results in a large quantity of reject materials, which are simply discarded as waste, with the consequent handling costs.These rejected components contain paper fibres, fibre debris(e.g.fines) fillers, ink and foreign matter, much of which could be reused in paper production replacing bought in raw materials.Other are suitable for use in other industries.The paper and board industry currently lacks the techniques for a more exhaustive.separation either to increase the fibre yield or to recover these components, both of which are economically significant to paper recycling costs.This project is aimed at laboratory scale development of these better, more selective, techniques for separation of returned paper's various components, both in the main stream and the reject paths of the recovery process.The projects overall objectives can be prioritised as follows:1. To maximise fibre reclamation. 2. To separate and return other components back to new paper. 3. To separate other components for use as raw materials within non-paper industries.By reducing this waste by 30-50%, the estimated saving to the European Community is calculated as up to 35 MECU per year in reduced handling costs.Subsequent reuse of the separated components would save an estimated further 30 MECU in production costs.
