(US5100066-A)      Cellulose material is produced from waste by removing decomposable and non-decomposable contaminants during pre-comminution, magnetic separation, air classification and fractionation resulting in a light fraction of paper, textiles and plastics material. The light fraction is washed to remove organic substances and contacted with H2O at a temp. of 30 to 50 deg.C in a pulper to comminute and dissolve the paper to produce cellulose fibres. The pulper contents are passed through an underwater screen to separate cellulose films and ballast.    ADVANTAGE -   Improved product quality from more economic process.    (JP6212584-A)      In processing household, industrial or other waste, to recover cellulose material, by comminution, magnetic sepn, sifting and fractionation, the light fraction from the sifting, consisting of paper, textiles and synthetics, is passed to a washing zone, and the washed material is fed to a pulper; after the pulper, ballast material is removed by sieving, and the cellulose particles supended in water, which pass through the sieve, are fed either directly, or after removing water by pressing, to paper mfr, or the pressed cellulose particles are dried and recovered as powder.    ADVANTAGE -   The following can be recovered: metals for re-use; minerals for the building industry; CH4 gas; agricultural prods, fertilisers and carriers; solid fuels; energy, electrical and thermal; cellulose powder as carrier and additive; and paper pulp for prodn of paper and card. Hand-sorting is avoided, valuable materials are completely utilised, only a small amt (a max of 3% of ash) of material has to be deposited, the system is independent of the compsn of the waste and is not limited to a single market, and harmless agricultural prods can be obtd. @(5pp Dwg.No.0/1)    (JP95062316-B2)      In processing household, industrial or other waste, to recover cellulose material, by comminution, magnetic sepn, sifting and fractionation, the light fraction from the sifting, consisting of paper, textiles and synthetics, is passed to a washing zone, and the washed material is fed to a pulper; after the pulper, ballast material is removed by sieving, and the cellulose particles supended in water, which pass through the sieve, are fed either directly, or after removing water by pressing, to paper mfr, or the pressed cellulose particles are dried and recovered as powder.
