Recycling some products only delays the landfill stage, since the material stemming from the recycling process has different features or is of worse quality. The end use changes and less recyclable objects are made which eventually end up in the landfill. In the case of glass, the material is recycled in the same production system (one container produces another) without any changes in its physical or chemical properties.
In its strictest sense, the circular economy means keeping the same resources within a continuous closed loop, avoiding the extraction of new virgin raw materials and the corresponding depletion of natural resources.
Consequently, glass containers are a magnificent example of a circular economy: glass is a material which, besides perfectly performing its function as a container, is also 100% recyclable an infinite number of times, without losing quality or quantity in the process. Thus, recycled glass can be put back into the production cycle it came from to replace the original raw materialsand be remade into a pure safe container to hold food and drink. In this way, it closes its circular trajectory and goes round and round again forever, saving energy and avoiding emissions.
Indeed, the magazine Nature has
recognized that glass recycling is like a hidden jewel that guarantees a carbonneutral future.
