Science Popularization | How to turn waste glass into treasure?

Various types of glass products play an important role in our lives, such as cups, bottles, lighting fixtures, screens for mobile phones and computers, which are highly durable, heat-resistant, and aesthetically pleasing.

What is the recycling process for waste glass? Does it turn waste into treasure and return to consumers again? Let's take a look together~

Note: Most glass products are recyclable, and recycled items should be kept clean and dry when placed to avoid contamination.

Waste glass recycling process

The glass on the market is mainly divided into colorless, green, and brown transparent glass. When delivering glass waste, be sure to handle it with care and pay attention to safety issues to avoid injuring yourself and garbage collectors. The recycled glass will be transported to professional glass processing manufacturers.

Because many sources of discarded glass come from beverage bottles, which may have packaging paper attached to them, aluminum strips wrapped around the bottle mouth, etc. The first step in garbage disposal is to remove impurities. After entering the factory, the first process is to repeatedly stir fry them with a forklift. Falling from the highest place and shattering.

This operation ensures that the fragments are relatively large, easy to concentrate, and also facilitates manual picking on the tracks, picking out packaging paper, aluminum strips, etc. that are about to fall off from the glass.

The glass here has different colors, and according to their different colors, they have different values and uses.

Use the transparency of glass and a spectroscopic analyzer to separate them. Highly crushed and made into glass sand, it has different uses. White glass sand can be directly melted and reused to make glass products and return to the market. Colored glass is mainly used as a filling material for building materials.

The Creativity of Recycling Waste Glass

——Foam fireproof bricks

Place candles on top of ordinary bricks and foam fireproof bricks made of glass sand, and then heat them under fire to test their heat transfer. After heating for a period of time, the candle on the ordinary brick slowly melted, while the candle on the fireproof brick remained unchanged. By comparing it with a thermometer, it can be seen more intuitively that the surface temperature of the ordinary brick reached 130 degrees. And the temperature of fireproof bricks is maintained within a comfortable range. Using this material to build a house is environmentally friendly, comfortable, and safe.
