Biodegradable BB Pellet

Abstract

The invention relates to a biodegradable BB pellet and preparation thereof.

1 . A biodegradable BB pellet comprising (a) a plant fiber material and (b) a binder.  
   
   
       2 . The pellet of  claim 1 , wherein the material is selected from the group consisting of vegetable food refuse, vegetable resin, vegetable fiber, wood flour, rice husk, rice straw, rice bran, wheat bran, sugar canes, bamboos, corn core and pulp.  
   
   
       3 . The pellet of  claim 1 , wherein the material is vegetable fiber.  
   
   
       4 . The pellet of  claim 1 , wherein the binder is starch or a biodegradable polymer.  
   
   
       5 . The pellet of  claim 4 , wherein the binder is starch.  
   
   
       6 . The pellet of  claim 1  further comprising a diluent selected from the group consisting of sodium sulfate, barium sulfate, calcium carbonate, potassium carbonate, cellulose, lactose, polylactic acid, polycaprolacton, polyhydroxybutyrate valerate and starch.  
   
   
       7 . The pellet of  claim 6 , wherein the diluent is calcium carbonate.  
   
   
       8 . The pellet of  claim 6 , wherein the diluent is polylactic acid or starch.  
   
   
       9 . The pellet of  claim 1  further comprising a lubricant selected from the group consisting of magnesium stearate and talc.  
   
   
       10 . The pellet of  claim 1 , wherein the plant fiber material and the binder is present at a weight ratio of the plant fiber material to the binder in the range of 100:1 to 1:100.  
   
   
       11 . The pellet of  claim 10 , wherein the weight ratio is in the range of 50:1 to 1:50.  
   
   
       12 . The pellet of  claim 6 , wherein the plant fiber material and the diluent is present at a weight ratio of the plant fiber material to the diluent in the range of 20:1 to 1:20.  
   
   
       13 . The pellet of  claim 12 , wherein the weight ratio is in the range of 5:1 to 1:5.  
   
   
       14 . A method of preparing a biodegradable BB tablet core comprising mixing a plant fiber material and a binder into a mixture, and allowing the mixture through granulation and molding.  
   
   
       15 . A method of preparing a biodegradable BB pellet comprising mixing a plant fiber material and a binder into a mixture, and allowing the mixture through granulation and molding.  
   
   
       16 . The method of  claim 15  further comprising allowing the mixture through coating and polishing.  
   
   
       17 . The method of  claim 15 , further comprising allowing the mixture through grinding and polishing.
