The glass container industry USES about 20 percent of the broken glass in its manufacturing process to facilitate melting and mixing with materials such as sand, limestone and other materials.75% of broken glass comes from the production of glass containers and 25% from the capacity after consumption.
The following problems should be noted when recycling waste glass packaging bottles (or broken glass) for raw materials of glass products.
(1) Fine selection and removal of impurities
Impurities, such as metal and ceramics, must be removed from glass container recyclers because glass container manufacturers need to use highly purified materials.For example, in broken glass there are metal caps and other oxides that may form to interfere with furnace operations;Ceramics and other foreign substances form defects in container production.
(2) Color selection
Recycling colors is also an issue.Because colored glass is not used in the manufacture of colorless flint glass, and only 10% green or flint glass is allowed in the production of amber glass, the broken glass after consumption must be colored manually or by machine.Broken glass can only be used to produce light green glass containers if it is not directly used for color selection.
