A method of zero discharge of papermaking liquids. Pulp composed of recycled fibers is initially purified to remove impurities, and the purified pulp is washed to remove soluble solids and chemicals, and the pulp is washed to make paper. Impurities are separated from the liquid residue after the purification operation, especially flotation purification. The liquid discharged from the purification section is evaporated to generate steam or water vapor and the residue is evaporated. The evaporation residue contains suspended solids removed from the liquid residue. The residue is sent to the mechanical dewatering section to reduce the water content, and the dewatered material can be used to fill or dispose of the material. The condensate from the evaporator can be used together with make-up water in the papermaking process. The water recovery in the papermaking process is the cycle of the washing operation. The water recovery of the washing slurry is reused in the pulp purification and pulping operations to achieve the liquid Zero emissions operation.
