Companies producing a domestic glass bottle use cullet, with its mixing ratio representing 60% out of the glass manufacturing raw materials, while Ansung Glass Industrial Co., Ltd. takes up 86% in the mixing ratio of cullet, reducing the material cost of a product and the use of energy by bringing down the energy basic unit, performing our mission as a environmentally friendly company in order to build a clean society by activating the use of recyclable cullet.

The active use of cullet prevents the corrosion of a glass melting furnace, a main facility of glass industry, on refractories, also helping extend the lifetime of a melting furnace.
