  • Waste paper treatment process
    Patent number: 5895556
    Abstract: A waste paper treatment process for the recycle and re-use of waste paper, which process comprises treating the waste paper, in a repulper, with a surfactant, in the absence of traditional repulper chemicals such as silicate, caustic and peroxide. The surfactant is preferably a copolymer of ethylene oxide and propylene oxide, and is used in a sufficient concentration to form ink agglomerates. The ink agglomerates are retained on the paper, rather than being removed as in waste paper deinking. The process permits the elimination of normal repulper chemicals, and reduces the amount of ink sludge generated, while providing acceptable brightness levels for the recycled pulp.
