Abstract: A hygienic disposal device for sanitary waste includes a supporting structure frame for mounting one or more components, including an opening lid hingedly connected to a hopper equipped with spray nozzles for disinfectant solution and water spraying. A shredder is connected to the hopper for shredding the waste, followed by a mixing chamber for homogenously mixing shredded waste with water. Valves at the bottom of the mixing chamber separate cellulose and plastic waste. Two rotating drums dewater and dry the separated waste, while a dryer blows hot air for further drying. An outlet discharges separated water into municipal sewage lines.

Abstract: The present invention relates to a method for treatment of polyhydroxyalkanoate (PHA) containing post-consumer product, the method comprising contacting a post-consumer product with a polypeptide that can catalyze degradation of the PHA, the contact taking place at a temperature at least 45° C. In a specific embodiment, the poly peptide is a wild-type PHA depolymerase expressed by a thermophilic microorganism or a modified PHA depolymerase that includes one or more single-site mutations as compared to the wild-type PHA depolymerase. In another specific embodiment, the polypeptide comprising a modified poly hydroxy butyrate (PHB) depolymerase comprising one or more single-site mutations as compared to SEQ ID NO: 1, and the modified PHB depolymerase having an optimum temperature of at least 45° C. The present invention also relates to a host cell transformed to express a polypeptide that catalyzes degradation of a PHA, the polypeptide having an optimum temperature for the degradation reaction of at least 45° C., wherein the host cell is selected from an E. coli cell or a thermophilic microorganism.

Abstract: A method for separating a fraction of super-absorbent polymers (SAP) from post-consumer absorbent sanitary products, said post-consumer absorbent sanitary products further including at least one cellulose fraction and one plastic fraction. The method includes the steps of sterilizing the post-consumer absorbent sanitary products and treating said post-consumer absorbent sanitary products by immersion in a bath with an aqueous solution containing at least one oxidizing compound. The oxidizing compound is preferably selected from the group consisting of sodium persulfate, potassium persulfate, ammonium persulfate, potassium monopersulfate, and hydrogen peroxide; preferably hydrogen peroxide. The treatment by immersion allows cross-link cleavage and solubilizing of the SAP contained in said post-consumer absorbent sanitary products, and obtaining a suspension comprising i) a solid fraction and ii) a liquid fraction, wherein the liquid fraction comprises linear polyacrylate derived from the cross-link cleavage and solubilization of SAP.

Abstract: Provided is a used paper diaper processing apparatus in which a water absorption function of a superabsorbent polymer that absorbs water contained in excrement is lowered and water is removed by mixing the superabsorbent polymer and a chemical containing divalent metal ions in an outer tank, and in which weight is reduced by dehydration after an amount of water contained in a used paper diaper is lowered. In the apparatus, a lower portion of the outer tank can be opened and closed, so that weight reduction processing and a series of operations including taking-out are possible. Since an operator is not required to take out the used paper diaper after processing directly from the outer tank, it is possible to reduce work and hygiene burdens on the operator.
