       18 . The resin composition of  claim 16 , wherein the ground waste has a particle size of 100 μm or less. 
   
   
       19 . The resin composition of  claim 16 , wherein the ground waste has a particle size of 25-80 μm. 
   
   
       20 . The resin composition of  claim 16 , wherein the ground waste has a particle size of 25-45 μm. 
   
   
       21 . The resin composition of  claim 16 , comprising 30% (per weight) or less of ground waste. 
   
   
       22 . The resin composition according to  claim 16 , comprising 21% (per weight) or less of ground waste. 
   
   
       23 . The resin composition of  claim 16 , wherein the ground waste originates from a material impregnated with a duroplast. 
   
   
       24 . The resin composition of  claim 16 , wherein the ground waste originates from a material impregnated with aminoplast or phenoplast. 
   
   
       25 . The resin composition of  claim 23 , wherein said duroplast is not fully cured. 
   
   
       26 . The resin composition of  claim 23 , wherein the duroplast exhibits a degree of condensation of 70% or less. 
   
   
       27 . The resin composition of  claim 23 , wherein the duroplast exhibits a degree of condensation of 20-40%. 
   
   
       28 . The resin composition of  claim 16 , comprising an amino resin. 
   
   
       29 . The resin composition of  claim 28 , wherein the amino resin is selected from the group consisting of melanin, urea resin, and a mixture thereof. 
   
   
       30 . A layered material, comprising a base material impregnated with a resin composition which is comprised of ground waste of resin impregnated material. 
   
   
       31 . The layered material of  claim 30 , wherein the base material is impregnated with a non-waste resin prior to being impregnated with the resin composition. 
   
   
       32 . The layered material of  claim 31 , wherein the base material is dried after being impregnated with the non-waste resin. 
   
   
       33 . The layered material of  claim 30 , wherein the base material is a paper with a paper weight of 40-120 g/m 2 . 
   
   
       34 . The layered material of  claim 30 , wherein the base material is a paper with a paper weight of 60-80 g/m 2 . 
   
   
       35 . A laminate, comprising:
 a layered material having a base material impregnated with a resin composition which is comprised of ground waste of resin impregnated material; and   a carrying layer,   wherein the layered material faces towards the carrying layer with a side being impregnated with the resin composition.   
   
   
       36 . A method of producing an impregnated layered material having a base material and a resin, said method comprising the step of impregnating the base material with a resin composition comprised of ground waste of resin impregnated material. 
   
   
       37 . The method of  claim 36 , further comprising the step of impregnating the layered material with a resin composition without ground waste of resin impregnated material (non-waste resin) prior to being impregnated with the resin composition. 
   
   
       38 . The method of  claim 37 , wherein the layered material is oriented towards the carrying layer with its side being impregnated with the resin corn position.
