Glass is a wonderful substance. It can be recycled over and over again. The good thing about glass recycling is that the glass retains its quality. Cullet, better known as domestic glass, is the most common glass. Imagine how many bottles of soda, juice and glass jars are used daily. If we were to simply throw them away, the environment would suffer greatly. It is therefore important that the culture of recycling be kept alive.

Advantages and Disadvantages of Glass Recycling. Some of them are listed below.
Advantages of Glass Recycling
- Recycling of Glass Saves Energy
Recycled glass melts at a lower temperature than its raw material components. The amount of energy required to make glass from scratch is 40% more than that needed to recycle it. If recycling is done on a large scale, maximum profit is achieved. Research has shown that recycling of a glass bottle can produce enough energy to light up a normal bulb for 4 hours.
- Recycling of Glass Reduces Industrial Pollution
The levels of pollutants that are released daily into the air around the world are very alarming. Recycled glass reduces the emissions of air and water pollution by around 20% and 40% respectfully. Reducing industrial pollution benefits not only the environment but also the entire ecosystem.
- Glass Recycling Pays
Some countries have capitalized on the financial gains that can be had from recycling glass. In America for instance, some states have recycling programs that offer cash incentives for most recycled glass products.
- Recycling of Glass Conserves Natural Resources
Recycling glass saves on the need to obtain more raw materials to make new glass. Industrialized nations with strong economies are aware that their economies grow more when monies do not have to be earmarked for tree planting or purchasing fossil fuels. By recycling glass, they save the natural resources that they already have.
- Recycling of Glass Conserves the Landscape
The aesthetic value of the environment is greatly improved through glass recycling. Many people tend to litter parks and parking lots with glass and another packaging. Due to the inorganic nature of glass, it will never decay. Recycling glass is very simple, and you can start the process by dropping the glass you have into recycling bins.
Disadvantages of Glass Recycling
- Not All Glass Can Be Recycled
Even though glass items can be recycled, there are a few exceptions. For example, glass from light bulbs and window panes cannot be recycled because they contain ceramics and other impurities that would contaminate the entire recycling process.
- Glass Recycling Creates Unemployment
It has been argued that glass bottle recycling has a significant impact on employment within the glass manufacturing industry. Millions of individuals who would have otherwise been gainfully employed providing manpower to create new glass items lose out on this opportunity as fewer people are needed to work in glass recycling plants.
- High Costs Associated With Glass Recycling
For glass to be properly recycled, it has to be separated by color. This process is quite labor intensive and rather complicated. Recycling in most countries is also done overseas due to a lack of proper facilities locally, making it very costly.
