Abstract: 
The technology of recycling of polymer-coated paper waste is described. Physical and chemical properties of fibers obtained from wallpaper wastes and from their derivative compositions were investigated. A special crusher with primary and secondary grinding stages and with a section for separating paper fibers from polymer coating was designed. Industrial trials of cellulose obtained from wallpaper wastes for the asbestos cement sheets manufacturing were held. Its impact on the quality and physical and mechanical properties of sheets was shown. Methods of thermogravimetry, microscopy, and differential thermal, infrared spectral and chemical analysis were applied to investigate cellulose fibers derived from recycled wallpaper. Their properties were compared to the ordinary cellulose and polyvinylacetate fibers, which are used in the production of asbestos cement sheets.
