Is broken waste glass recyclable

Pulished on Apr. 11, 2019

In recent years, with the rapid improvement of the level of modern technology, the old and traditional glass industry has been renewed, and various glass products with unique functions have been launched. These glasses not only have the traditional light transmission effect, but also play an irreplaceable role in some special occasions. If you want to know how to recycle the broken waste glass, you’ll know after reading this article.

1, Is broken waste glass recyclable?

The former glass container industry uses about 20% of the cullet in the manufacturing process to promote melting and mixing with raw materials such as sand, limestone and alkali. 75% of the broken glass comes from the production process of glass containers, and 25% comes from after consumption.

Disposal of waste glass bottles (or broken glass frit) for the recycling of raw materials for glass products, the following issues should be noted:

1.1 Accurate selection to remove impurities

Impurities such as metal and ceramics must be removed from the glass bottle. This is because glass container manufacturers need to use high-purity raw materials. For example, there are metal covers in broken glass that may form oxides that interfere with furnace operation; ceramics. And other foreign substances form defects in the production of containers.

1.2 Color selection

Recycling color is also a problem. Because colored glass can't be used in the manufacture of colorless flint glass, only 10% green or flint glass is allowed when producing amber glass. Therefore, the broken glass must be artificial after consumption. Or the machine chooses the color. If the broken glass is used directly without color making, it can only be used to produce light green glass containers.

2, What are the ways to reuse broken glass?

2.1 Unheated, Non-heating type utilization is also called mechanical type utilization. The specific method is to directly pulverize according to the use situation or firstly pre-treat the recovered worn glass by washing, sorting, drying, etc., and then pulverize them into small particles by mechanical means. Or grinding into small glass balls for use. The utilization methods are as follows:

2.11, Use of glass cullet as a combination of pavement, building brick, glass wool insulation and honeycomb structural material.

2.12, The pulverized glass is directly mixed with the components of the building materials to prepare the whole building prefabrication.

2.13 , The smashed container glass can also be used to make reflector materials and clothing accessories.

2.14, Used to decorate the surface of a building to give it a beautiful optical effect.

2.15, Can be directly ground into a variety of shapes, and then bonded into crafts or small decorations such as buttons, etc.

2.16, Mixture of glass and plastic waste can be molded into synthetic slate products.

2.17, Can be used to produce sewage pipes

2.2 Heated type, The heating type is made by mashing the waste glass, melting it with a high-temperature melting furnace, and then using the rapid drawing method to obtain the glass fiber. The glass fiber can be widely used for making asbestos tile, glass cylinder and various building materials.
