Off gases from the leaching step are used to provide heat to the drying step. The drying step provides a product well suited to being turned into pellets for reuse.

A method is provided to fabricate a green desiccant wheel. A green recycled adsorbent material of aluminum hydroxide and alumina is extracted and used as a base material to be added to a 3-dimensional (3D) network skeleton of a foam support. Through sintering, surface is hardened with the material adsorbed to megapores uniformly distributed. Thus, an adsorbent material of porous ceramic having pores on surface is made. The area contacting with moist air is increased. The moisture-adsorbing capacity is improved. At last, the whole procedure is integrated to develop a high-efficiency green desiccant wheel. Thus, the reusable materials are kept at innate grade or upgraded for recycling and regenerating. New materials and products can be further fabricated. The present invention helps solving environmental problem of wastes. Life cycle of resource is lengthened. A sample of recycling economy is innovated. Industrial efficiency is effectively enhanced.

The treating method for a positive electrode for a non-aqueous electrolyte secondary battery is a treating method for a positive electrode for a non-aqueous electrolyte secondary battery which comprises a positive electrode having a foil containing Al and an active material which is a metal composite oxide, the method comprising: conducting a heating treatment for heating the positive electrode (heating step); melting the positive electrode using heat of reaction of the foil and the active material to obtain a molten material (melting step); and separating the molten material into a metal material containing a metal constituting the metal composite oxide and a slag (separating step). By subjecting the positive electrode to heating treatment, a reduction reaction of the positive electrode can be promoted at a low cost.
