The recycling process consists of 5 stages, beginning with the collection of a used glass and ending up with the molding into new products. The first stage is glass production. First of all, the raw material such as sand, soda ash, limestone, and other chemicals are mixed. Then, the raw material is melted in a glass furnace with the temperature approximately 1500 ° C.
