We all know that the glass is recycled in the green binBut not all of us know why it is important to recycle glass. It is a material that can be recycled in its entirety, in addition to an unlimited number of times. Recycling glass helps reduce energy consumption, reduces waste, thereby reducing pollution and environmental problems and, also, the consumption of other raw materials. To go deeper, then in this Green Ecologist article, we will talk about why is it important to recycle glass.
It is important to recycle glass because with the simple gesture of recycling our glass bottles, and other pieces of this material, you can achieve:
Glass is a material that is present in bottles, glasses or light bulbs and is one of the most abundant components of garbage, both industrial and domestic.
The glass recycling process begins with its selective collection in the green container. Once this step is done, it is continued with its cleaning by treating it with chemical products, which manage to eliminate possible dirt, sand or grease. Then plastic, paper and other debris items are also removed. When the glass is clean, it is passed through sieves until it reaches the desired granulometry. Subsequently, all possible metal remains are removed by using magnets. The resultant of these processes is the calcin o crushed glass and prepared to be melted again. Finally, it is mixed 50% with sand, sodium hydroxide and limestone. Thus, it is obtained recycled glass and with the same properties as the one that is manufactured.
In the countries of the European Union a minimum recycling of 60% of glass is required, Spain exceeded that figure in 2007, but in countries such as Sweden, Switzerland or Belgium, the figures exceed 90%.
Ecoglass is the waste management system that promoted the green dot, in which glass manufacturers pay a tax that finances the recycling of packaging. In Spain, the glass recycling process consists of recovering the containers and transforming them into calcine in recycling plants (as we have already explained), however in countries like Germany it is possible to reuse containers without subjecting them to new manufacturing processes, but simply with washing them is enough.
Green containers that selectively collect glass, began to be installed in Spanish cities and towns during the 80s and today, they collect most of the glass. For example, between 2003 and 2007, around 10 kg of glass were collected per inhabitant to almost 15. According to the Ministry of the Environment, citizens are much more aware of the need to recycle glass. However, outside the home environment such as at work, on the street, at school or in universities, there is still much to do.
Furthermore, this material is highly reusable and can be recycled an unlimited number of times. For example, here we leave you simple ideas to reuse and recycle crystal and glass bottles.
