Abstract

Avfallspapir, spesielt kontoravfall som omfatter laserpapir og/eller fotoko- pieringspapir, gjennomgår en avsverting ved massedannelse i nærvær av en vannløselig anionisk polymer ved en i hovedsak nøytral pH-verdi og deretter flotasjon i nærvær av et kationisk overflateaktivt middel.Waste paper, especially office waste comprising laser paper and / or photocopying paper, undergoes de-wetting by mass formation in the presence of a water-soluble anionic polymer at a substantially neutral pH and then flotation in the presence of a cationic surfactant.
