Supply recycling system and valuable-metal recovering system

Abstract

A supply recycling system for recycling supply goods used in an office-automation equipment includes a toner refilling process including removing waste toner from a toner bottle retrieved from a market, and filling the toner bottle with new toner; and a steelmaking-dust molding process including blending the waste toner removed at the toner refilling process with steelmaking dust, and molding the steelmaking dust blended with the waste toner.

         3 . The supply recycling system according to  claim 1 , wherein 
 the steelmaking-dust blended with the waster toner is at least one of 
 a dust recovered from exhaust gas of a steel manufacturing process;  
 a scale recovered from a steel-annealing process or a steel-pickling process; and  
 an aluminum refuse formed from aluminum dross, aluminum ash, and aluminum slag generated at aluminum refining, and  
   the steelmaking-dust molding process further includes 
 placing the steelmaking dust molded into an electric furnace or a ladle refining furnace; and  
 recovering a metal contained in the steelmaking dust molded as a valuable metal.  
   
     
     
         4 . The supply recycling system according to  claim 3 , wherein 
 the toner refilling process further includes determining a necessary amount of the waste toner to be supplied to the steelmaking-dust molding process based on information on an amount of waster toner demanded at the steelmaking-dust molding process, and    the steelmaking-dust molding process further includes 
 determining a necessary amount of molding based on information on an amount of steelmaking-dust-molded product demanded from a steel manufacturer; and  
 supplying the steelmaking-dust-molded product to the steel manufacturer.  
   
     
     
         5 . The supply recycling system according to  claim 4 , wherein the toner refilling process further includes 
 setting a product code for the waste toner to be supplied to the steelmaking-dust molding process, and    setting, when sending the necessary amount of the waste toner to the steelmaking-dust molding process, a manufacturing code per shipped lot.    
     
     
         6 . The supply recycling system according to  claim 1 , wherein 
 The toner refilling process further includes determining a necessary amount of the toner bottle based on information on an amount of toner demanded from an office-automation-equipment manufacturer or an office-automation-equipment distributor; and    supplying the toner bottle refilled to the office-automation-equipment manufacturer or the office-automation-equipment distributor.    
     
     
         7 . The supply recycling system according to  claim 6 , wherein the toner refilling process further includes 
 setting a product code for the toner to be supplied to the office-automation-equipment manufacturer or the office-automation-equipment distributor; and    setting, when sending the necessary amount of the toner to the office-automation-equipment manufacturer or the office-automation-equipment distributor, a manufacturing code per shipped lot.    
     
     
         8 . The supply recycling system according to  claim 4 , wherein the information is transferred via communication.  
     
     
         9 . The supply recycling system according to  claim 6 , wherein the information is transferred via communication.  
     
     
         10 . The supply recycling system according to  claim 8 , wherein the communication is carried out via an Internet communication using an information processing device.  
     
     
         11 . The supply recycling system according to  claim 9 , wherein the communication is carried out via an Internet communication using an information processing device.  
     
     
         12 . The supply recycling system according to  claim 8 , wherein each of the toner refilling process and the steelmaking-dust molding process includes 
 a data storing unit that stores the information transmitted and received; and    an output unit that outputs the information.    
     
     
         13 . The supply recycling system according to  claim 9 , wherein each of the toner refilling process and the steelmaking-dust molding process includes 
 a data storing unit that stores the information transmitted and received; and    an output unit that outputs the information.    
     
     
         14 . The supply recycling system according to  claim 1 , wherein the toner bottle retrieved from the market is either of a used toner bottle inside the office-automation equipment and a toner bottle retrieved as used supply goods.  
     
     
         15 . The supply recycling system according to  claim 1 , wherein 
 the waste toner is color toner, and    the toner refilling process further includes separating respective colors of yellow, magenta, cyan, and black of the color toner.    
     
     
         16 . A valuable-metal recovering system for recovering a valuable metal contained in a steelmaking-dust-molded product from the steelmaking-dust-molded product, wherein 
 the steelmaking-dust-molded product is obtained by a supply recycling system for recycling supply goods used in an office-automation equipment, and    the supply recycling system includes 
 a toner refilling process including removing waste toner from a toner bottle retrieved from a market, and filling the toner bottle with new toner; and  
 a steelmaking-dust molding process including blending the waste toner removed at the toner refilling process with steelmaking dust, and molding the steelmaking dust blended with the waste toner.
