ABSTRACT:
Due to ever-increasing waste production and ever-dwindling landfill space, alternatives to throwing away disposable diapers is needed. The present invention relates generally to a recycling process for reclaiming used paper and plastic materials. The process comprises a first step of shredding the used disposable diapers into small pieces, which facilitates the separation of the plastics from the pulp-like filler material. The shredded matter is then washed in a solution comprising water containing various ecologically-safe cleaning agents, as well as calcium chloride and salt to neutralize the acrelites in the pulp-like material. The shredded matter is then washed in a washer comprising a perforated cylindrical drum, which spins and forces the slurry through the perforations, while retaining the plastic material. The slurry-like material containing pulp is then dehydrated. The separate plastic and dehydrated pulp-like materials can then be sold for recycling.
