Glass

The main component of glass is silicon dioxide (SiO2), which generally accounts for 70% or more. Other raw materials for glass production include “soda” (Na2CO3) or potassium alkali (K2CO3) and quick lime (CaO). These mineral raw materials are widely distributed around the world, with abundant reserves and very low prices. The chemical properties of glass are very stable, therefore when it is buried in landfills, it only takes up space without causing chemical changes or degradation, and does not release substances that are harmful to the environment. However, it will constantly occupy the landfill space.

Recyclable glass:

 

Drink glass bottles, such as wine bottles, soda bottles, juice bottles, etc.

Seasoning bottle

Other glass containers

 

 

Non-recyclable glass:

 

Tempered glass, such as cooking utensils, glass windows, crystals, etc.

Glass mixed with chemicals or impurities, such as mirrors, light bulbs, light pipes, light boxes, etc.

Perfume or cosmetic bottle

 

Recycle method:

 

Make sure to remove the beverage (or food / sauce) inside the bottles properly. Keep in mind four steps of cleaning and recycling glass bottles:

 

1. remove the bottle cap;

2. Empty the remaining content;

3. Simple cleaning;

4. Place gently and recycle.

Most of the currently recovered glass bottles are processed to produce environmentally friendly floor tiles after being processed in Hong Kong, or used as fillers for local reclamation or site formation works, or exported for recycling. In addition, there are many professionals who will use upcycle glass bottles to make glassware.
