Abstract

Fremgangsmåte for behandling av av- fallspapir for resirkulering og gjenan- vendelse av avfallspapir, omfattende be- handling av avfallspapiret i en repulper med et overflateaktivt middel, fortrinns- vis i fravær av tradisjonelle repulper- kjemikalier, så som silikat, kaustikk og peroksyd. Det overflateaktive middel er fortrinnsvis en kopolymer av etylenoksyd og propylenoksyd, og anvendes i en konsen- trasjon som er tilstrekkelig til å danne sverteagglomerater som forblir i papiret som i hovedsak ikke-synlige agglomerater i stedet for å bli fjernet fra den resir- kulerte masse som ved tradisjonell avsver- ting av avfallspapir. Fremgangsmåten til- later eliminering av vanlige kjemikalier for gjendannelse av masse, og reduserer mengden av sverteslam som genereres under tilveiebringelse av akseptable lyshetsni- våer for den resirkulerte masse.
