There are several types of glass recycling: as casting flux, transformation, recycling, raw material recovery and reuse, etc.
Broken glass can be used as a flux for smelting cast steel and cast copper alloys to cover the molten metal to prevent oxidation.
Transformational utilization is a recycling method that needs to be developed urgently. In the future, there will be many new and value-added technologies for transformational utilization. After the pretreated cullet is processed into small glass granules, it can be used in the following ways:
(1) Using glass fragments as a combination of road surfaces, several years of tests in the United States and Canada have confirmed that using glass fragments as road fillers can reduce the accident of vehicle lateral slippage compared with other materials; the reflection of light is suitable; the road surface Good wear and tear; snow melts quickly, suitable for use in places with low temperatures.
(2) Mix the crushed glass with building materials to make building products such as building prefabricated parts and building bricks. Practice has proved that the dimensional accuracy and strength of products formed by pressure molding with organic substances as binders are high, and the production cost is low.
(3) The crushed glass is used to make building surface decorations, reflector materials, arts and crafts and clothing accessories, with beautiful visual effects.
(4) The mixture of glass and plastic waste and building materials can be made into synthetic building products, etc.
After pretreatment of the recovered glass, it is returned to the furnace to melt and manufacture glass containers, glass fibers, etc.
The recycled cullet is used as the added raw material for glass products, because adding cullet in an appropriate amount helps the glass to melt at a lower temperature.
The scope of reuse of packaging is mainly for low-value and large-volume commodity packaging glass bottles. Such as beer bottles, soda bottles, soy sauce bottles, vinegar bottles and some canned bottles.
